Investing in the ADSs involves significant risks. You should carefully consider all of the information in this prospectus before making an investment in the ADSs. Below please find a summary of the principal risks we face, organized under relevant headings.

If we fail to increase student enrollments, our net revenues may decline, and we may not be able to maintain growth.

We generate revenue primarily from the tuition we collect from our students. It is critical for us to enroll prospective students in a cost-effective manner. Some of the factors, many of which are largely beyond our control, could prevent us from successfully increasing enrollments of new students in a cost-effective manner, or at all. These factors include, among other things, (i) reduced interest in the degrees, diplomas, professions or certifications for which our course offerings are designed; (ii) negative publicity or perceptions regarding us, or online education services in general; (iii) the emergence of alternative course delivery models; (iv) the inability of students to pay the tuition; (v) increasing market competition, particularly price reductions by competitors that we are unable or unwilling to match; and (vi) adverse changes in relevant government policies or general economic conditions. If one or more of these factors reduce market demand for our services, our student enrollments could be negatively affected or our costs associated with student acquisition and retention could increase, or both, any of which could materially affect our ability to grow our gross billings and netrevenues. These developments could also harm our brand and reputation, which would negatively impact our ability to expand our business.

~~We have grown rapidly and expect to continue to invest in our growth for the foreseeable future.~~ If we fail to manage ~~this~~our business growth effectively, the success of our business model will be compromised.

We have experienced rapid growth in gross billings and net revenues in recent years, primarily driven by our fast-growing student enrollments since our transition to an online course delivery model in 2014 which allows students to access our courses from anywhere connected to the internet. Our net revenues grew by 131.6% from RMB418.9 million in 2016 to RMB970.2 million in 2017 and further increased by 103.5% to RMB1,974.0 million (US$287.1 million) in 2018. Over the same periods, our gross billings grew by 221.4% to RMB2,381.8 million from RMB741.0 million and further increased by 35.0% to RMB3,214.4 million (US$467.5 million).

Our ~~rapid~~ growth strategy has placed, and will continue to place, a significant strain on our sales and marketing capacities, administrative and operating infrastructure, facilities and other resources. To maintain our growth, we need to continue to acquire more students, scale up our course offerings, increase our academic and administrative faculty, as well as strengthen our platforms and systems. We will also be required to refine our operational, financial and management controls and

reporting systems and procedures. If we fail to efficiently manage ~~this expansion of~~ our business expansion, our costs and expenses may increase more than we plan and we may not successfully attract a sufficient number of students and qualified academic and administrative faculty in a cost-effective manner, respond to competitive challenges, or otherwise execute our business plans. In addition, we may, as part of carrying out our growth strategies, adopt new initiatives to offer additional course packages and educational content and to implement new pricing models and strategies. We cannot assure you that these initiatives may achieve the anticipated results. These proposed changes may not be well received by our existing and prospective students, in which case their experience with our education services may suffer, which could damage our reputation and business prospect.

Our ability to effectively implement our strategies and manage ~~any significant growth of~~ our business growth will depend on a number of factors, including our ability to: (i) identify and effectively market our products and services in new markets with sufficient growth potential; (ii) develop and improve course offerings and educational contents to make them appealing to existing and prospective students, particularly working adult students; (iii) maintain and increase our student enrollments; (iv) effectively recruit, train and motivate a large number of new employees, including our faculty members and sales and marketing personnel; (v) successfully implement enhancements and improvements to the systems and platforms; (vi) continue to improve our operational, financial and management controls and efficiencies; (vii) protect and further develop our intellectual property rights; and (viii) make sound business decisions in light of the scrutiny associated with operating as a public company. These activities require significant capital expenditures and investment of valuable management and financial resources, and our growth will continue to place significant demands on our management. There are no guarantees that we will be able to effectively manage any future growth in an efficient, cost-effective and timely manner, or at all. Our growth in a relatively short period of time is not necessarily indicative of results that we may achieve in the future. If we do not effectively manage the growth of our business and operations, our reputation, results of operations and overall business and prospects could be negatively impacted.

Our net revenues were RMB1,974.0 million, RMB2,193.9 million and RMB2,203.8million (US$337.7 million), respectively, in 2018, 2019 and 2020. During the same periods, our gross billings were RMB3,214.4 million, RMB2,358.5 million and RMB2,350.4 million (US$360.2 million), respectively, and our new student enrollments were 526,014, 363,013and 434,240, respectively. Our new student enrollments increased in 2020, primarily due to the increase in professional skills and general interest courses catering to growing demands for diverse personal education. We are seeking to offer a broader range of courses, foster a more social and entertaining learning experience, and use cutting-edge technologies, particularly artificial intelligence, to improve students’ learning experience and outcomes. All of these endeavors involve risks and will require significant management, financial and human resources. We cannot assure you that they will achieve the anticipated results or that our gross billings and new student enrollments will not decline in the future due to the risks and uncertainties discussed in this “Item 3.D. Risk Factors.” If we are not able to achieve growth in our gross billings and new student enrollments effectively, or at all, our business and prospects may be materially and adversely affected.

We have a history of net losses and we may not achieve profitability in the future.

We had net losses of ~~RMB253.6~~RMB927.0 million, ~~RMB918.7~~RMB395.2 million and ~~RMB927.0~~RMB431.0 million (US$~~134.8~~66.1 million) in ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, respectively. We cannot assure you, however, that our net loss will be narrowed or that we will be able to generate net profits in the future.

We expect that our sales and marketing expenses will continue to increase as we invest in branding and sales and marketing efforts, including engaging additional sales and marketing personnel, whether employed by us or contracted by us through third-party service providers, investing in data analytics in the student counseling and sales process, and broadening our online marketing channels. In addition, we intend to continue to invest heavily for the foreseeable future in increasing our market share, improving the capacity of our technology infrastructure to better support an even larger student base and to offer additional courses and educationalcontent.

These efforts may be more costly than we expect and our net revenues may not increase sufficiently to offset these expenses. We may continue to take actions and make investments that do not generate optimal short-term financial results and may even result in increased operating losses in the short term with no assurance that we will eventually achieve our intended long-term benefits or profitability. These factors, among others set out in this “Item 3.D. Risk Factors,” may negatively affect our ability to achieve profitability in the near term, if atall.

If we are unable to conduct sales and marketing activities cost-effectively, our results of operations and financial condition may be materially and adversely affected.

We rely ~~heavily~~ on our sales and marketing efforts to increase student enrollments. Our sales and marketing expenses primarily include expenses incurred in relation to sales and marketing personnel and marketing spending. We incurred approximately ~~RMB503.6~~RMB2,152.8 million, ~~RMB1,351.8~~RMB1,792.3 million and ~~RMB2,152.8~~RMB2,123.6 million (US$~~313.1~~325.5 million), respectively, in sales and marketing expenses in ~~2016, 2017~~2018, 2019 and ~~2018. We expect our sales and marketing expenses to continue to increase in the future as we further expand our operations.~~2020.

Our sales and marketing activities may not be well received by the market and may not result in the levels of sales that we anticipate. We also may not be able to retain or engage a sufficient number of experienced sales and marketing personnel, or to train newly onboard sales and marketing personnel, which we believe is critical to implementing our sales and marketing strategies cost-effectively. Further, sales and marketing approaches and tools in China’s online education market are evolving rapidly. This requires us to continually enhance our sales and marketing approaches and experiment with new methods to keep pace with industry developments and student preferences. Moreover, our sales and marketing activities may be deemed to violate PRC laws and regulations, and we may be exposed to administrative penalties, such as paying fines or publishing explanatory notes to limit the adverse effects of our marketing efforts. If we are deemed guilty of significant infringements, we may be ordered to cease sales and marketing activities temporarily and our business license may be revoked. Failure to engage in sales and marketing activities in a compliant and cost-effective manner may reduce our market share, cause our revenues and gross billings to decline, negatively impact our profitability, and materially harm our business, financial condition and results of ~~operation.~~operations.

We may be adversely affected by any negative publicity concerning us and our business, shareholders, affiliates, directors, officers and employees and the industry in which we operate, regardless of its accuracy, that could harm our reputation and business.

Negative publicity about us and our business, shareholders, affiliates, directors, officers, and teachers and other employees, as well as the industry in which we operate, can harm our operations. We have been exposed to negative publicity concerning refund dispute and administrative penalty and alleged improper or misleading statement made in our sales and marketing activities in the past. Negative publicity concerning these parties could be related to a wide variety of matters, including, but are not limited to:

In addition to traditional media, there has been an increasing use of social media platforms and similar devices in China, including instant messaging applications, such as Weixin/WeChat, social media websites and other forms of internet-based communications that provide individuals with access to a broad audience of consumers and other interested persons. The availability of information on instant messaging applications and social media platforms is virtually immediate as is its impact without affording us an opportunity for redress or correction. The opportunity for dissemination of information, including inaccurate information, is seemingly limitless and readily available. Information concerning our company, shareholders, directors, officers and employees may be posted on such platforms at any time. The risks associated with any such negative publicity or incorrect information cannot be completely eliminated or mitigated and may materially harm our reputation, business, financial condition and results of operations.

We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.

~~Beijing~~Wuhan Shangde Online Education Technology Co., Ltd., or Wuhan Shangde, our wholly owned subsidiary, and Beijing Sunlands and ~~Tianjin Shangde Online Education Technology Co., Ltd., or Tianjin Shangde,~~a number of other VIEs, through which we operate our online education business, currently do not hold a private school operating permit, ~~for our online education services,~~ and we may be subject to risks of administrative sanctions due to our lack of such permit.

Pursuant to the Administrative Regulations on Educational Websites and Online and Distance Education Schools promulgated by the Ministry of Education of the PRC, or the MOE, on July 5, 2000, “educational websites and online education schools” that provide educational services in relation to higher education, elementary education, pre-school education, teaching education, occupational education, adult and other education and public educational information services, are subject to approval from competent education authorities, depending on the type of education service provided. In February 2016, the State Council issued a government decision which explicitly withdrew the above-mentioned approval requirement. See “Item 4. Information on the Company—4.B. Business Overview—Regulation— Regulations on Online and Distance Education.” On November 7, 2016, China’s National People’s Congress passed an amendment to the Promotion of Private Education Law, or the Amendment, which became effective on September 1, 2017. The Amendment applies different regulatory requirements to non-profit and for-profit private schools. ~~See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules.”~~

In December 2016, several PRC government agencies, including the MOE, the State Administration for Industry and Commerce which has now merged into the newly-established State Administration for Market Regulation, or the ~~SAIC,~~SAMR), and the Ministry of Human Resources and Social Welfare, jointly promulgated the Implementation Rules on the Supervision and Administration of For-profit Private Schools, or the Implementation Rules. Under the Implementation Rules, the establishment, division, merger or any other material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare and be registered with the competent local branch of ~~SAIC,~~SAMR, and a duly approved private school will be granted a private school operating permit. The Implementation Rules also provide that the provisions contained therein should be applicable to “for-profit private training institutions” in an analogous manner. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules.”

As of the date of this annual report, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to our lack of a private school operating permit for our online education services. In August 2018, the Ministry of Justice, or MOJ, published the draft amendment to the Regulations on the Implementation of the Law for Promoting Private Education of the PRC, or MOJ Draft, for public comment. According to the MOJ Draft, online diploma-awarding education service providers shall obtain a private school operating permit and we, as an online non-diploma-awarding training service provider, shall file with the department of education at the provincial level. The MOJ Draft further stipulates that the internet technology service platform that provides the training and educational activities shall review and register the identity information of institutions or individuals applying for access to the platform. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules.” As of the date of this annual report, the MOJ Draft is still pending final approval and has not come into effect. It is uncertain when and how the MOJ Draft would be signed into law and how local government would promulgate and implement rules related to the filing or licensing requirement applicable to online education service providers. In addition, we have made inquiries to the relevant education authorities and were informed that online education service providers were not required to obtain a private school operating permit for the provision of online education services, and that if such educational authorities were to require us to obtain a private school operating permit in the future, such authorities would not subject us to penalties for the provision of our services without obtaining a private school operating permit. Nonetheless, as advised by Tian Yuan Law Firm, our PRC legal counsel, the current PRC laws and regulations, including the Amendment and the Implementation Rules, remain unclear as to whether the requirement for a private school operating permit is applicable to an online education service provider. We cannot assure you that the PRC government will not in the future require us to obtain a private school operating ~~permit, given the lack of clear and consistent statutory interpretation regarding the implementation of the Amendment and the Implementation Rules and other relevant laws and regulations.~~permit. If the PRC government requires us to obtain a private school operating permit or introduces additional amendments and guidelines to expand the coverage of the Amendment to explicitly cover online education service providers, and if we fail to do so, we may be subject to fines up to five times the illegitimate gains generated from the provision of training services without a proper license, other administrative sanctions, such as being ordered to refund tuition payments to the students, or criminal liabilities, for our lack of a private school operating permit. In addition, uncertainties exist as new laws and regulations, including without limitation the for review draft of Implementation Rules of the Promotion of Private Education Law, or the draft Implementation Rules, published by the Ministry of Justice in August, 2018, may require online education service providers to obtain private school operating permit or make filing with its competent provincial department of education or department of human resources and social security. It is uncertain when the draft would be signed into law and whether the final version would have any substantial changes from the draft. If enacted as the draft, we may be unable to obtain the private school operating permit or complete the required filing in a prompt manner or incur additional costs in complying with relevant requirements, which may adversely affect our business, financial conditions and results of operations.

We may also be subject to regulatory requirements that are more stringent than the ones currently applicable to us, including those relating to sales and marketing, courses and educational content offerings, teachers’ qualification, as well as tuition fee rates and tuition refund policies, or laws and regulations that require us to obtain and maintain additional licenses and permits, and we may incur substantial expenses or alter or change our business to comply with theserequirements. For example, on November 28, 2019, Beijing Administration for Market Regulation published the draft of Administrative Measures on Supervision and Service of the Prepaid Consumption of Beijing and the draft of Administrative Rules on Prepaid Consumption of the Academic After-school Training Institutions of Beijing for public comment. According to such measures and rules, (i) if a consumer requests a refund before the courses start, the training institution shall offer a full refund within 15 business days upon the refund requirement, (ii) if a consumer requests a refund before the completion of half of the courses, the corresponding fee may be deducted by the training institution according to the proportion of the completed courses, and the remaining part shall be refunded in a lump sum within 15 business days, (iii) if a consumer requests a refund after the completion of half of the courses, the training institution may not refund any tuition fee, and (iv) any refund for installment credit consumption shall comply with applicable regulations. In addition, pursuant to the Interim Measures of Wuhan for the Administration of Private Training Institutions promulgated by Wuhan Municipal Government effective on March 15, 2018, private training institutions shall abide by the following provisions with respect of refund fees: (i) if a student requires a refund before the beginning of the course, the institution shall refund all the fees paid to it with deduction of the educational service fees and other fees actually incurred; (ii) if a student requires a refund after the beginning of the course, the institution shall refund the remaining part of the fees after deducting the corresponding proportion of the tuition fees, the fees for collection and management and the relevant taxes and fees in accordance with the proportion of the class hours completed; (iii) where an institution fails to fulfill the commitments with the student, and the student requires a refund, the institution shall refund all the fees paid by the student; and (iv) the institution shall complete the examination and verification within three working days upon the receipt of the refund requirement and shall refund to the student within 30 days. It is uncertain as to whether and how such measures and rules would be applicable to us, and whether any future laws and regulations with respect to the tuition refund requirements for online education service providers like us will be introduced. We have been exposed to refund dispute between us and our students in the past. We cannot assure you that if we are subject to more stringent refund regulatory requirements, we can adjust our refund policy to comply with these requirements on a timely manner, which may cause us more refund disputes with our students and may have a material and adverse effect on our business, operating results and financial condition.

Under the Amendment and the Implementation Rules, a material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare before it can be registered with the competent local branch of ~~SAIC.~~SAMR. If we were required to expand the authorized scope of our business license to cover our business of online education services, which shall be registered with the ~~SAIC,~~SAMR, to comply with applicable licensing requirements, we may not able to do so before we have obtained a private school operating permit. If any of the foregoing were to happen, our business operations may be disrupted, and our financial condition, results of operations and reputation may be materially and adversely affected.

Moreover, the MOE, jointly with certain other PRC government authorities, promulgated the Opinions on Guiding and Regulating the Orderly and Healthy Development of Educational Mobile Apps on August 10, 2019, or the Opinions on Educational Apps, which requires, among others, mobile apps that offer services for school teaching and management, student learning and student life, or home-school interactions, with school faculty, students or parents as the main users, and with education or learning as the main application scenarios, be filed with the competent provincial regulatory authorities for education before the end of 2019. In addition, on November 11, 2019, MOE issued the Administrative Measures on Filing of Educational Mobile Apps, which requires, among others, that filings of existing educational mobile apps shall be completed before January 30, 2020. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations on Online and Distance Education.” Our educational mobile apps Shangde Jigou and Shangde Zikao have been filed with competent regulatory authority as required under the Opinions on Educational Apps. However, as the Opinions on Educational Apps are relatively new and evolving, we cannot assure you that we are in full compliance with all relevant rules and will be able to complete or maintain such filing in relation with any of our new apps and comply with other regulatory requirements under the Opinions on Educational Apps in a timely manner, or at all. If we fail to promptly complete such filing and comply with other applicable regulatory requirements, we may be subject to fines, regulatory orders to suspend our operations or other regulatory and disciplinary sanctions.

In addition to the existing regulatory regime, it is uncertain whether and how the PRC government would promulgate additional laws and regulations regarding the online education industry, and there is no assurance that we can comply with any such newly promulgated laws and regulations in a timely manner, or at all. Our failure to fully comply with these existing and future laws and regulations may materially and adversely affect our business, financial condition and results of operations.

We face regulatory risks and uncertainties associated with our teachers’ lack of teaching licenses.

Pursuant to the Implementation Rules, the teachers employed by a for-profit private school shall obtain the teaching licenses or relevant professional skill qualifications required by PRC laws and regulations, although the definition or the scope of the “relevant professional skill qualifications” is not explicitly stated in the Implementation Rules. A substantial majority of our teachers currently do not hold teaching licenses.

As of the date of this annual report, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to the lack of teaching licenses. ~~As advised by Tian Yuan Law Firm, our PRC legal counsel, the~~The current PRC laws and regulations, including the Amendment and the Implementation Rules, remain unclear as to whether the ~~Implementation Rules is applicable to~~teachers of an online education service provider who provides non-diploma post-secondary and professional education like us ~~and accordingly, whether our teachers~~ are required to obtain and hold teaching licenses. We cannot assure you that the PRC government authorities will not take a contrary view. In the event that in the future our teachers are required by laws to obtain teaching licenses, we cannot assure you that they can meet the requirements for applying for teaching licenses. If our teachers are not able to apply for and obtain the teaching licenses on a timely basis, or at all, we may be ordered to rectify such noncompliance or subject to penalties under the then-effective PRC laws and regulations, in which case our business may be disrupted, and our financial condition, reputation and prospects would be materially and adverselyaffected.

We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs.

On December 20, 2007, the State Administration of Press Publication Radio Film and Television, or SAPPRFT, and the Ministry of Industry and Information Technology, or ~~the~~ MIIT, jointly promulgated the Administrative Provisions on Internet Audio Visual Program Services, or the Audio Visual Program Provisions, which became effective on January 31, 2008 and were amended on August 28, 2015. Among other things, the Audio Visual Program Provisions stipulate that no entities or individuals may provide Internet audio-visual program services without a License for Online Transmission of Audio-Visual Programs issued by SAPPRFT or completing the relevant filing with SAPPRFT or its local bureaus, and only state-owned or state-controlled entities are eligible to apply for a License for Online Transmission of Audio Visual Programs. On April 1, 2010, SAPPRFT promulgated the Provisional Implementations of Tentative Categories of Internet Audio Visual Program Services, or the Categories, which clarified the scope of Internet audio-visual programs services, which was amended on March 10, 2017. According to the Categories, there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. Sub-category No. 3 to the second category covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. Sub-category No. 5 of the first category and sub-category No. 7 of the second category cover the live broadcasting of important political, martial, economic, social, cultural, sports activities or events or general social or community cultural activities, sports games and other organized activities. However, there are still significant uncertainties relating to the interpretation and implementation of the Audio Visual Program Provisions, in particular, the scope of “internet audio-visual programs.” See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Online Transmission of Audio-Visual Programs.”

We deliver our courses in live streaming format. Our teachers and students communicate and interact live with each other via our virtual learning community. The audio and video data are transmitted through the platforms between specific recipients instantly without any further redaction. We believe the nature of the raw data we transmit distinguishes us from general providers of internet audio-visual program services, such as the operator of online video websites, and the provision of the Audio-Visual Program Provisions are not applicable with regard to our offering of the courses. However, we cannot assure you that the competent PRC government authorities will not ultimately take a view contrary to our opinion. In addition, we also offer video recordings of live streaming courses and certain other audio-video contents on our online platforms to our students as supplementary course ~~materials on our platforms.~~materials. If the government authorities determine that our offering of the courses fall within the relevant category of Internet audio-visual program services under the Categories, we may be required to obtain the License for Online Transmission of Audio Visual Programs.

The Categories describe “Internet audio-visual program services” in a very broad, vague manner and are unclear as to whether online courses, whether delivered in a live streaming format or through video recordings, fall into the definition of audio-visual programs. We have made inquiries to the relevant bureaus of SAPPRFT and were informed that online educational content provided through live streaming or recorded courses does not fall within the scope of internet audio-visual programs, the transmission of which does not require a License for Online Transmission of Audio-Visual Programs. We cannot assure you that the PRC government will not ultimately take a view that live streaming or recorded courses or any other content offered on our platforms are subject to the Audio Visual Program Provisions. We currently do not hold a License for Online Transmission of Audio Visual Programs, and since we are not a state-owned or state-controlled entity, we

are not eligible to apply for such license. If the PRC government determines that our content should be considered as “internet ~~audio- visual~~audio-visual programs” for the purpose of the Audio-Visual Program Provisions, we may be required to obtain a License for Online Transmission of Audio Visual Programs. We are, however, not eligible apply for such license since we are not a state-owned or state-controlled entity. If this were to occur, we may be subject to penalties, fines, legal sanctions or an order to suspend the provision of our live streaming courses. As of the date of this annual report, we have not received any notice of warning or been subject to penalties or other disciplinary action from the relevant governmental authorities regarding the lack of a License for Online Transmission of Audio Visual Programs in conducting of our business.

Our failure to obtain and maintain other approvals, licenses, permits or ~~permits~~filings applicable to our business could have a material adverse impact on our business, financial conditions and results of operations.

A number of PRC regulatory authorities, such as the ~~SAIC,~~SAMR, the Cyberspace Administration of China, the MITT, the SAPPRFT, and the State Council Information Office, the Ministry of Civil Affairs, and the Ministry of Human Resources and Social Welfare, oversee different aspects of our business operations, and we are required to obtain a wide range of government approvals, licenses, permits and ~~permits~~filings in connection with ouroperations.

We currently do not hold several approvals, licenses and permits that are required for certain aspects of our business operations. Under the current PRC laws and regulations, the provision of our educational content through our online platform may be considered “online publishing” and may require us to obtain an Internet Publishing License, which we currently do not have. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Online Publishing.” As of the date of this annual report, we have submitted an application to the competent government authorities for the approval of an Internet Publishing License. However, we may not be able to receive the approval for such licenses in a timely manner, or at all.

~~Furthermore, Beijing Sunlands and Tianjin~~One of our subsidiaries, Wuhan Shangde, has registered “online educational training” in its authorized scope of business. However, our ~~consolidated~~ VIEs, and certain of their operating subsidiaries currently do not include “occupational training” and “educational facilitation services” in their authorized scope of business. Before the Amendment was issued, we attempted to apply to the competent authorities in Beijing to add “occupational training” and “educational facilitation services” to the authorized scope of business of Beijing Sunlands, but our application was rejected by such authorities without being provided any formal explanations for such rejection. After the issuance of the Amendment, basedBased on our consultation with the competent government authorities in Beijing, such government authorities currently may not accept applications for inclusion of “occupational training,” “educational facilitation services” or similar items in the scope of business of companies that do not hold a private school operating permit. For additional information about the private school operating permit, see “—We face risks associated with our lack of a private school operating permit for ouronline education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.” Even if our application were to be accepted, there is no assurance that it will be approved by the government authorities in a timely fashion, or at all. If it comes to the attention of the government authorities that ~~Beijing Sunlands or Tianjin Shangde is~~our VIEs and their operating subsidiaries are operating beyond their respective authorized scope of business, we may be subject to fines, confiscation of the gains derived from the noncompliant operations, or may be required to cease ~~Beijing Sunlands’ or Tianjin Shangde’s~~our VIEs’ noncompliant operations. In addition, we deliver courses in live streaming format on our proprietary live streaming platform which the relevant authorities may regard as a live-streaming platform and may thus require us to make necessary filings as a live-streaming platform. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Internet Live Streaming Services.”

As of the date of this annual report, we have not been subject to any fines or other form of regulatory or administrative penalties or sanctions due to the lack of any the above-mentioned approvals, licenses or, ~~permits.~~permits or filings. However, we cannot guarantee that the government authorities will not impose any penalties or sanctions on us in the future, which may include warnings, fines, mandates to remedy any violations, confiscation of the gains derived from the services for which approvals, licenses, permits or ~~permits~~filings are required, and/or an order to cease to provide such services. In addition, we cannot guarantee that the government will not promulgate new laws and regulations that require additional licenses, permits, approvals and/or ~~approvals~~filings for the operation of any of our existing or future business. If we are unable to obtain such licenses, permits, approvals or ~~approvals~~filings in a timely fashion, we could be subject to penalties and operational disruption and our financial condition and results of operations could be adversely affected.

We may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members.

Our faculty members are key to the quality of our educational services, as well as our brand and reputation. Our ability to continue to attract faculty members, including teachers and mentors, with necessary experience and qualifications is a key driver in the success of our business. We seek to recruit qualified faculty members who are dedicated to teaching and are able to communicate with our students in an interactive online setting.

Additionally, given the interactive nature of our live streaming lessons, we tend to hire teachers and mentors with strong education background and good communication skills enabling them to engage and interact with students. The market for recruitment of faculty members in China is competitive. In order to recruit qualified full-time teachers and mentors, we must provide candidates with competitive compensation packages and offer attractive career development opportunities.

Although we have not experienced major difficulties in recruiting or training qualified teachers and mentors in the past, we cannot guarantee we will be able to continue to recruit, train and retain a sufficient number of qualified faculty members in the future as we continue to expand our course offerings and business scale, which may have a material adverse effect on our business, financial condition and results of operations.

We may not be able to timely improve or expand our course and educational content offerings in a ~~cost- effective~~cost-effective manner to make them appealing to existing and prospective students, or at all.

We regularly and constantly update our existing courses and educational content and develop new courses and educational content to meet student’s demand and the latest market trends. The revisions, improvements and expansions of our existing course and content offerings and the development of new course and content offerings may not be accepted by existing or prospective students. Even if we are able to develop acceptable new course and educational content offerings, we may not be able to introduce them as quickly as students require or as quickly as our competitors introduce competing offerings. The process of performing detailed market research and recruiting qualified faculty for new course and educational content offerings could be costly and ~~time- consuming.~~time-consuming. Furthermore, offering new courses or content or upgrading existing ones may require us to make significant investments in educational content development, increase sales and marketing efforts and reallocate resources from other uses, all of which may not be successful. If we are unsuccessful in pursuing course and educational content development and upgrading opportunities due to the financial constraints, failure to attract qualified faculty, or other factors, our ability to attract and retain students could be impaired and our financial results could suffer.

~~The online live streaming industry~~We believe that, even with the proliferation of internet and mobile devices in China, remains relatively young and untested, and there are limited proven methods to project user demand or preference or available industry standards on which we can rely. In the PRC, few institutions with large student enrollments have in the past adopted a live streaming course delivery model, and some of our target students may still be inclined to choose traditional face-to-face lessons offered by offline learning ~~centers~~providers over online courses as they find the former more ~~familiar~~intimate and reliable. We cannot assure you that our live streaming course delivery format will continue to be attractive to our students in the future. If our live streaming course delivery model becomes less appealing to our students, our business and prospects may be affected. In addition, ~~as we continue to increase our student enrollments,~~ there is no assurance that our live streaming capacity will be able to support a growing number of students accessing our courses online without any service interruptions.

Furthermore, we cannot assure that we will be able to address PRC regulatory and legislative developments relating to online streaming business. See “—We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs” and “—Our failure to obtain and maintain other approvals, licenses, permits or filings applicable to our business could have a material adverse impact on our business, financial conditions and results of operations.”

We are subject to the risks associated with third-party live streaming service providers.

Currently, while we rely on ~~third-party service providers to support~~ our ~~online~~proprietary live streaming ~~course delivery.~~

~~Currently,~~platform to deliver online courses, we ~~rely upon~~also use certain third-party vendors to provide live streaming services to support our online course delivery. Because the live streaming technologies and infrastructure are owned and managed by third parties, any problems with the reliability and performance of such technologies and infrastructure could result in unanticipated delays and unscheduled service interruption could further cause us to be unable to deliver our courses in a live streaming format, forcing us to resort to using prerecorded lectures. Our inability to deliver live streaming courses during service interruptions may damage the quality of our education service and student engagement and experience and negatively impact our reputation, financial condition and results of operations.

We do not maintain long-term arrangements with our live streaming service providers. The term of the service agreements we enter into with third-party live streaming service providers are generally one year. If we cannot renew such agreements upon their expirations or terminations on commercially reasonable terms, or at all, or if the live streaming service providers become unwilling or unable to provide us with live streaming services at any time for any reasons, our ability to deliver live streaming online courses will be severely impacted, and our students’ learning experience and our reputation will beharmed.

We have developed our own proprietary live streaming platforms in 2018 and expect the platforms to be put into operation in the third quarter of 2019. There is, however, no assurance that we will succeed. If the development of proprietary live streaming technologies does not achieve the anticipated results, we may have to continue to rely on third-party vendors to provide us with the technologies and infrastructure necessary for the delivery of our online live streaming courses, which may negatively impact our business and prospects.

Failure to adequately and promptly respond to changes in the exams our students must take to pursue their desired degrees, diplomas or certifications could cause our education services to be less attractive to our students.

There have been continuous changes in the curriculum requirements associated with, and the format of, the exams our existing and prospective students must take to pursue their desired degrees, diplomas or certifications, the manner in which the exams are administered, as well as topics frequently tested in the exams. These changes require us to continually update and enhance our course offerings, our educational content and our teaching methods. Any inability to track and respond to these changes in a timely and cost-effective manner would make our education services less attractive to students, which may

materially and adversely affect our reputation and ability to continue to attract students without a significant decrease in our tuition. In addition, as we further expand our course offerings, we cannot assure that we will be able to adapt our existing educational content and methods to new courses that we have limited experience in teaching.

We may face risks associated with the installment tuition payment plan we offer to our students.

In 2015, we launched an installment payment option enabling eligible students to obtain loans from accredited third-party credit providers in China to finance all or part of their tuition. The third-party credit providers are responsible for performing credit assessment, approving loan applications, providing the funds, and collecting delinquent loan payments. Under the loan agreement between the borrowing student and the lending credit provider, the borrowing student is obligated to repay the loan principal in installments over a period ranging from three to 1218 months. Under the cooperation agreement between us and each credit provider, we are obligated to pay the full amount of interest payable under a loan, as financial service fees, to the credit provider. We ~~generally~~ do not provide any guarantees for the repayment of student loans in favor of the credit providers. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our student loan coverage ratio was ~~32.3%~~78.3%, ~~72.9%~~70.4% and ~~78.3%~~54.9%, respectively. For the same periods, we made interest payments of ~~RMB20.2~~RMB159.9 million, ~~RMB106.2~~RMB118.0 million and ~~RMB159.9~~RMB83.3 million (US$~~23.3~~12.8 million), respectively, to the creditproviders.

As part of our long-term sales and marketing strategy, we plan to continue to make the interest payments for our students under their loans and pay service fees to the credit providers, which may place significant strains on our financial resources as our student enrollments continue to grow. We may be subject to risks associated with an increase in interest rates to the extent that we continue to make interest payments for the loans taken by our students. If we cease to do so due to increases in interest rates or for other reasons, our course packages may become more costly for our students to purchase, which could in turn negatively impact our business, financial condition and reputation.

The availability of funding from our existing and potential credit providers depends on many factors, such as their liquidity and capital sufficiency, the legal and regulatory environment, the general economic conditions, default rates of our students on the loans, and, where applicable, the availability of lenders on the credit providers’ platforms. In addition, our credit providers may seek to acquire borrowers independently instead of through cooperation with us. We currently work with a limited number of credit providers and we cannot assure you that our credit providers will continue to cooperate with us on commercially favorable terms, or at all, or that existing or potential credit providers will be able to provide loans in a sufficient amount to meet our students’ borrowing needs. If any of these were to occur, our course packages may become less compelling to prospective students who wish to obtain student loans, and as a result our business and financial condition may be negatively affected.

Disruption to or failures of our IT infrastructure could reduce student satisfaction and could harm our operations.

The performance and reliability of our IT infrastructure is critical to our operations and reputation. We provide our course offerings and educational content to our students and faculty primarily through our applications and platforms built upon Genesis, our proprietary IT infrastructure. In addition, our employees, including our faculty and sales and marketing personnel, rely on our integrated IT infrastructure to carry out their marketing, sales, operation and teaching functions. As part of their educational experience, our students interact with their peers and our faculty via our platforms on a frequent basis. Accordingly, any errors, defects, disruptions or other performance problems with our IT infrastructure could damage our reputation, decrease student satisfaction and retention, adversely impact our ability to attract new students and expand our course offerings, and materially disrupt our operations. If any of these occur, our business operations, reputation and prospects could be harmed.

Our business depends on the continued success of our brand “Sunlands,” and if we fail to maintain and enhance recognition of our brand, we may face difficulty enrolling new students, and our reputation and operating results may be harmed.

We believe that market awareness of our brand “Sunlands” has contributed significantly to the success of our business. Maintaining and enhancing our brand are critical to our efforts to grow our student enrollments and gross billings. Failure to maintain and enhance our brand recognition could have a material and adverse effect on our business, operating results and financial condition. We have devoted significant resources to our brand promotion efforts in recent years, but we cannot assure you that these efforts will be successful. If we are unable to further enhance our brand recognition, or if we incur excessive marketing and promotion expenses, or if our brand image is negatively impacted by any negative publicity, our business and results of operations may be materially and adversely affected.

Students may decide not to continue taking our courses for a number of reasons, including a perceived lack of improvement in their academic performance or general dissatisfaction with our course and educational content offerings, which may adversely affect our business, financial condition, results of operations and reputation.

The success of our business depends on our ability to deliver high-quality learning experiences and help students achieve their learning objectives. We may not always be able to meet our students’ expectations in terms of academic performance due to a variety of reasons, many of which are outside of our control. We may face increased dropout rates and student dissatisfaction due to our students’ perceptions of our failure to help them achieve their anticipated academic goals, our students’ overall dissatisfaction with the quality of our course and educational content offerings and our faculty, as well as changing views of the value of the diplomas, degrees and qualifications they are pursuing through taking our courses. These factors may contribute to reduced student engagement and increased challenges in attracting and enrolling prospective students, all of which may adversely affect our prospects, business, financial condition, results of operations andreputation.

We face risks associated with our reliance on our STE course offerings, including risks resulting from changes in government policies or requirements relating to STE exams.

Our course offerings are concentrated to our Self-taught Higher Education Examination, or the STE course offerings, namely post-secondary courses designed for students pursuing associate diplomas or bachelor’s degrees by taking the STE exams. STE course offerings represent a significant portion of our net revenues, gross billings and new student enrollments. Our STE course offerings accounted for approximately ~~66.3%~~85.8%, ~~80.6%~~80.5% and ~~85.8%~~66.8%, respectively, of our net revenues and approximately ~~79.0%~~88.3%, ~~89.2%~~75.1% and ~~88.3%~~53.1%, respectively, of our gross billings in ~~2016, 2017~~2018, 2019 and ~~2018.~~2020. During the same periods, our STE course offerings accounted for approximately ~~61.7%~~80.1%, ~~80.1%~~75.4% and ~~80.1%~~46.2%, respectively, of our new student enrollments.

Our reliance on STE course offerings may expose us to concentration risks. If there are significant reductions in the perceived value of degrees or diplomas our students are pursuing through the STE exams, or if the PRC government releases substantial updates to the requirements or formats of the STE exams and we are unable to upgrade our course or educational content offerings to address such developments in a timely manner, the demand for and attractiveness of our STE course offerings may be adversely affected, which could have an adverse impact on our financial condition and results of operations.

If we fail to effectively identify, pursue and consummate strategic alliances or acquisitions, our ability to grow and to achieve profitability could be impacted.

We may from time to time engage in evaluations of, and discussions with, possible domestic and international acquisition or alliance candidates. We may not be able to identify suitable strategic alliances or acquisition opportunities, complete such transactions on commercially favorable terms, or successfully integrate business operations, infrastructure and management philosophies of acquired businesses and companies. There may be particular complexities, regulatory or otherwise, associated with our expansion into new markets, and our strategies may not succeed beyond our current markets. If we are unable to effectively address these challenges, our ability to execute acquisitions as a component of our long-term strategy will be impaired, which could have an adverse effect on our growth.

We face intense competition in our industry, which could divert student to our competitors, lead to pricing pressure and loss of market share, and significantly reduce our gross billings and net revenues.

China’s post-secondary and professional education market is intensely competitive. We compete with other online education service providers or traditional offline players, for student enrollments and engagement, high-quality academic and administrative faculty, and sales and marketing personnel, among other things. Some of our current and future competitors may have substantially greater name recognition and financial and other resources than we do, which may enable them to compete more effectively for potential students and decrease our market share. We also expect to face competition as a result of new entrants to the post-secondary and professional education market.

We may not be able to compete successfully against current or future competitors and may face competitive pressures that could adversely affect our business or results of operations. For example, increased competition may result in pricing pressure for us in terms of the tuition we are able to negotiate to receive from a student. In addition, online education is characterized by rapid changes in students’ technological requirements and expectations and evolving market standards, and our competitors may develop platforms or other technologies that are superior to the platform and technology we use. These differences may affect our ability to recruit and retain students, which may render our online ~~delivery format~~course offerings less competitive. The increasingly competitive landscape may also result in longer and more complex sales cycles with a prospective student or a decrease in our market share, any of which could negatively affect our gross billings and net revenues and our ability to grow our business.

If our security measures are breached or fail and result in unauthorized disclosure of data by our employees or our third-party agents, we could lose existing students, fail to attract new students and be exposed to protracted and costly litigation.

Maintaining platform security is of critical importance to our students because the platform stores and transmits proprietary and confidential information, which may include sensitive personally identifiable information that may be subject to stringent legal and regulatory obligations. As an online education service provider, we face an increasing number of threats to our IT infrastructure, including unauthorized activity and access by our employees or third-party agents, system viruses, worms, malicious code and organized cyberattacks, which could breach our security and disrupt our business. For example, we have introduced data security and confidentiality protocols into the cooperation agreements we enter into with third-party sales agents with whom we share prospective students’ contact information, and we have made technical improvements in our IT infrastructure to prevent unauthorized access of confidential or sensitive personal information by our employees and third-party sales agents in the process of engaging prospective students. These measures, however, may not be as effective as we anticipate. In addition, there is no assurance that our third-party sales agents will comply with contractual and legal requirements with respect to data privacy when they collect data from our prospective students. If our security measures are breached or fail as a result of third-party action, employee error, malfeasance or otherwise, we could be subject to liability or our business could be interrupted, potentially over an extended period of time. Any or all of these issues could harm our reputation, adversely affect our ability to attract and enroll prospective students, cause prospective students not to enroll or stay enrolled, or subject us to third-party lawsuits, regulatory fines or other action or liability. Further, any reputational damage resulting from breach of our security measures could create distrust of our company by prospective students or investors. We may be required to expend significant additional resources to protect against the threat of these disruptions and security breaches or to alleviate problems caused by such disruptions or breaches.

Privacy concerns could limit our ability to collect and leverage our user data and disclosure of user data could adversely impact our business and reputation.

In the ordinary course of our business and in particular in connection with conducting sales and marketing activities with our existing and prospective students as well as the utilization of our AI-powered personalized study programs, we collect and utilize data supplied by our users. We currently face certain legal obligations regarding the manner in which we treat such information. Increased regulation of data utilization practices, including self-regulation or findings under existing laws that limit our ability to collect, transfer and use data, could have an adverse effect on our business. In addition, if we were to disclose data about our users in a manner that was objectionable to them, our business reputation could be adversely affected, and we could face potential legal claims that could impact our operating results.

Internationally, we may become subject to additional and/or more stringent legal obligations concerning our treatment of customer and other personal information, such as laws regarding data localization and/or restrictions on data export. Failure to comply with these obligations could subject us to liability, and to the extent that we need to alter our business model or practices to adapt to these obligations, we could incur additional expenses.

We are subject to a variety of laws and other obligations regarding data protection, any failure to comply with applicable laws and obligations could have a material adverse effect on our business, financial condition and results of operations.

We are subject to various regulatory requirements relating to the security and privacy of data, including restrictions on the collection, storage and use of personal information and requirements to take steps to prevent personal data from being divulged, stolen, or tampered with. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection.” Regulatory requirements regarding the protection of data are constantly evolving and can be subject to differing interpretations or significant change, making the extent of our responsibilities in that regard uncertain. For example, the Cybersecurity Law of the PRC became effective in June 2017, but there are great uncertainties as to the interpretation and application of the law. It is possible that those regulatory requirements may be interpreted and applied in a manner that is inconsistent with our practices. In addition, the Office of the Central Cyberspace Affairs Commission, the MIIT, the Ministry of Public Security, and the SAMR jointly issued an announcement on January 23, 2019 regarding carrying out special campaigns against mobile internet application programs collecting and using personal information in violation of applicable laws and regulations, which prohibits business operators from collecting personal information irrelevant to their services, or forcing users to give authorization in disguised manner. In addition, the PRC regulatory authorities have recently taken steps to strengthen the regulation on data protection and conducted several rounds of relevant inspections recently. We have been taking and will continue to take reasonable measures to comply with such announcement, provisions and inspection requirements. However, as these announcements and provisions are relatively new, and the related implementation rules have yet been promulgated, it remains uncertain how these announcements and provisions will be implemented. We cannot assure you we can adapt our operations to it in a timely manner.

Any failure, or perceived failure by us to maintain the security of our students’ data and other confidential information or to comply with applicable privacy, data security and personal information protection laws, regulations, policies, contractual provisions, industry standards, and other requirements, may result in civil or regulatory liability, including governmental or data protection authority enforcement actions and investigations, fines, penalties, enforcement orders requiring us to cease operating in a certain way, litigation, or adverse publicity, and may require us to expend significant resources in responding to and defending allegations and claims. Furthermore, the PRC regulatory and enforcement regime with regard to privacy, data security and personal information protection is still evolving. PRC regulators have been increasingly focused on regulation in the areas of data security and data protection. We cannot assure you that relevant regulators will not interpret or implement these laws or regulations in ways that negatively affect us. It is possible that we may become subject to additional or new laws and regulations, which may result in additional expenses to us and subject us to potential liability and negative publicity. We expect that these areas will receive greater attention and focus from regulators, and attract continued or greater public scrutiny and attention going forward, which could increase our compliance costs and subject us to heightened risks and challenges associated with data security and protection. If we are unable to manage these risks, we could become subject to penalties, fines, suspension of business and revocation of required licenses, and our reputation and results of operations could be materially and adversely affected.

Tuition refunds or potential refund disputes may negatively affect our cash flow, financial condition, and reputation.

We offer different tuition refund options to our students depending on the time of enrollment and subject to certain conditions and restrictions in the service contract between us and each of our students. Generally, a student is offered a full, unconditional refund within 24 hours upon enrollment. If the student makes a refund request after taking at least one live streaming course lasting 30 minutes by reason of any material academic issue of our courses within certain refund period, we ~~would~~ offer ~~such student~~ a ~~partial~~ refund excluding the registration fees and the ~~relevant academic~~ fees ~~for the trial lesson~~of delivered courses upon our confirmation. In addition, ~~at our discretion,~~we offer students a ~~partial~~ refund ~~may also be granted~~for the undelivered courses excluding the registration fees. Prior to June 2019, such refund was provided only within seven days upon enrollment while starting from June 2019, we offer such refund during the ~~student who withdraws at any other time during his or her enrollment, subject to special approval by us.~~entire service period. When calculating gross billings for a specific period, we deduct the total amount of refunds from the total amount of cash received for the sale of course packages for such period. See “Item 4. Information on the Company—4.B. Business Overview—Our Tuition and Fees.”

In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, we had made ~~RMB61.3~~RMB 276.4 million, ~~RMB150.1~~RMB345.9 million and ~~RMB276.4~~RMB335.5 million (US$~~40.2~~51.4 million) of refund payments, respectively, most of which were made pursuant to our tuition refund policy, see “Item 4. Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” The number of refund requests and the amount of refunds could be affected by a number of ~~factors, many of which are beyond our control.~~factors. These factors include, without limitation to, student dissatisfaction with our teaching quality and our course and educational content offerings, privacy concerns relating to our online platforms, negative publicity regarding us or online education in general, the terms and scope of our refund policy, and any change or development in PRC laws and regulations with respect to fees and tuitions charged by online education providers like us. See “—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry, including the Law for Promoting Private Education and its Implementing Rules.” As part of our efforts to enhance user experience, from June 2019, we amended certain terms of our refund policy to facilitate a more flexible and smoother refund process. Any refund payments that we may be required to make to our students, as well as the expenses we could incur for processing refunds and resolving refund disputes, could be substantial and could adversely affect our gross billings, net revenues, liquidity and financial condition. A high volume of refunds and refund disputes may also generate negative publicity that could harm our reputation. We have experienced in the past, and may experience in the future, negative publicity in relation to refund disputes between us and our students, which may significantly harm our brand name and divert our attention from operating our business.

We cannot assure you that we will not be subject to liability claims or legal or regulatory liability for any inappropriate or illegal content, which could subject us to liabilities and cause damages to our reputation.

Although we implement various monitoring procedures to identify and remove inappropriate or illegal content, we cannot assure you that there will be no inappropriate or illegal content included in our content offerings including content generated and uploaded to our online platforms by our users. For example, we have been historically penalized for inaccurate advertising. We may face civil, administrative or criminal liability or legal or regulatory sanctions, such as requiring us to restrict or discontinue our content, products or services, if an individual or corporate, governmental or other entity believes that any of the content offerings violates any laws, regulations or governmental policies or infringes upon its legal rights. Even if such a claim were not successful, defending such a claim may cause us to incur substantial costs. Moreover, any accusation of inappropriate or illegal content in our content offerings could lead to significant negative publicity, which could harm our reputation, business, financial condition and results of operations.

Our success depends on the continuing efforts of our senior management team and other key employees.

We depend on the continued contributions of our senior management and other key employees, including, in particular, Mr. Jianhong Yin, also known as Peng Ou, our founder and the chairman of our Board of Directors, and Mr. Tongbo Liu, our director and Chief Executive Officer. The loss of the services of any of our senior management or other key employees could harm our business. Competition for qualified talents in China is intense. If one or more of our senior management or other key employees are unable or unwilling to continue in their present positions, we may not be able to find replacements in a timely manner, or at all, and our business may be disrupted. Moreover, if any member of our senior management team or any of our other key personnel joins a competitor or forms or invests in a competing business, we may lose student enrollments, qualified teaching faculty members and other key sales and marketing personnel to our competitors. Our future success is also dependent on our ability to attract a significant number of qualified employees and retain existing key employees. If we are unable to do so, our business and growth may be materially and adversely affected. Our need to significantly increase the number of our qualified employees and retain key employees may cause us to materially increase compensation-related costs, including share-based compensation.

If we cannot maintain our corporate culture as we grow, we could lose the innovation, collaboration and focus that contribute to our business.

We believe that a critical component of our success is our corporate culture, which fosters innovations and has roots in a deep understanding of our students and the evolving education industry in China. As we continue to expand and grow our business, we may find it difficult to maintain these valuable aspects of our corporate culture. Any failure to preserve our culture could undermine our reputation in the marketplace and negatively impact our ability to attract and retain employees and students, which would in turn jeopardize our future success.

We may from time to time be subject to infringement claims relating to intellectual properties of third parties.

We cannot assure you that our course offerings and educational contents and our IT technologies and platforms do not or will not infringe upon copyrights or other intellectual property rights held by third parties. We may encounter disputes from time to time over rights and obligations concerning intellectual properties, and we may not prevail in those disputes.

We have adopted policies and procedures to prohibit our students and employees from infringing upon third-party copyright or intellectual property rights. However, we cannot ensure that they will not, against our policies, use third-party copyrighted materials or intellectual property without proper authorization in our classes or via any medium through which we provide our services. We may incur liability for unauthorized duplication or distribution of materials posted on our websites or used in our classes. We have been involved in claims against us alleging our infringement of third-party intellectual property rights and we may be subject to such claims in the future. We have not entered into any licensing arrangements with, or otherwise obtained any consent from, the government agencies administering the STE exams for using certain exam questions in our quiz banks. Although we have never been subject to any legal or administrative penalties or proceedings relating to our use of these sample questions, we cannot assure you that we will not be subject to infringement claims associated with our use of real STE questions in the future. Any such intellectual property infringement claim could result in costly litigation and divert our management attention and resources, which in turn could negatively affect our business, financial condition andprospect.

If we fail to protect our intellectual property rights, our brand and business may suffer.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Although we seek to obtain copyright or patent protection for our intellectual property when applicable, it is possible that we may not be able to do so successfully or that the copyright or patent we have obtained may not be sufficient to protect all of our intellectual property rights. In particular, we rely, to the great extent, upon our educational content developed in-house, including course syllabi and outlines, quiz banks, teaching notes, and learning outcomes trees, to provide high-quality online education services. Despite our efforts to protect our proprietary education contents and other intellectual property rights, unauthorized parties may attempt to copy or duplicate our intellectual property or otherwise use our intellectual properties without obtaining our consent. Monitoring unauthorized use of our intellectual property is difficult and costly, and we cannot be certain that the steps we have taken will effectively prevent misappropriation of our intellectual properties. If we are not successful in protecting our intellectual property rights, our business and results of operations may be adverselyaffected.

Our students, employees and third-party vendors may engage in intentional or negligent misconduct or other improper activities or misuse our platform, which could harm our brand and reputation.

We are exposed to the risk of fraud or other misconducts committed by our students, employees and vendors, including certain third-party sales and marketing agencies. For example, in some instances, our students and our faculty members may post to our platform articles or other third-party content for use in class discussions. The PRC laws governing the fair use of these third-party materials are imprecise and adjudicated on a case-by-case basis, which makes it challenging for us to adopt and implement policies governing these practices. We could, as a result, incur liability to third parties for the unauthorized duplication, distribution or other use of these materials. Any such claims could subject us to costly litigation and impose a significant strain on our financial resources and attention of management personnel regardless of whether the claims have merit. ~~Additionally, we~~We may be required to alter or cease our uses of such materials, which may include changing or removing content from courses or altering the functionality of our platform, or to pay monetary damages. Fraud or other misconducts by our students, employees or third parties may also involve engaging in unauthorized misrepresentation to our potential students and misappropriating third-party intellectual property and other propitiatory rights during marketing activities, misusing sensitive personal information of our students, and engaging in bribery or other unlawful payments, any of which could result in customer complaints, regulatory and legal liabilities, as well as serious harm to our brand and reputation.

Our courses undergo multiple rounds of internal review before being broadly released. While we proactively monitor our live courses and other content and communications to ensure that we are able to identify content that may be deemed inappropriate or in violation of laws, regulations and government policies, since we have limited control over the real-time and offline behavior of our users and employees, to the extent any improper behavior is associated with our content and services, our ability to protect our reputation may be limited. If any of our users and employees suffer or allege to have suffered harm following contact initiated through our services, we may face civil lawsuits or other liabilities. In response to allegations of illegal or inappropriate activities, PRC government authorities may intervene and hold us liable for non-compliance with PRC laws and regulations concerning the dissemination of information on the internet and subject us to administrative penalties or other sanctions, such as requiring us to restrict or discontinue our content or services. As a result, our business may suffer and our reputation, business, financial condition and results of operations may be materially and adversely affected.

We may be the subject of detrimental conduct by third parties such as our competitors, including complaints to regulatory agencies and the public dissemination of malicious assessments of our business, which could have a negative impact on our reputation and cause us to lose market share, students and revenues, and adversely affect the price of theADSs.

We have been, and in the future may be, the target of anti-competitive, harassing or other detrimental conduct by third parties including our competitors. Such conduct may include complaints, anonymous or otherwise, to regulatory agencies regarding our operations, accounting, business relationships, business prospects and business ethics. Additionally, allegations, directly or indirectly against us, may be posted online by anyone, whether or not related to us, on an anonymous basis. We may be subject to government or regulatory investigation as a result of such third-party conduct and may be required to expend significant time and incur substantial costs to address such third-party conduct, and there is no assurance that we will be able to conclusively refute each of the allegations within a reasonable period of time, or at all. Our reputation may also be materially negatively affected as a result of the public dissemination of anonymous allegations or malicious statements about our business, which in turn may cause us to lose students and revenues, and adversely affect the price of the ADSs.

Our user metrics and other estimates are subject to inaccuracy in measuring our operating performance, which may harm our reputation.

We continually review number of students, new student enrollments, gross billings per new student enrollment, and other operating metrics to evaluate growth trends, measure our performance and make strategic decisions. These metrics are calculated using internal data, have not been validated by an independent third party and may not be indicative of our future operating performance. While these numbers are based on what we believe to be reasonable estimates for the applicable period of measurement, there are inherent challenges in measuring how our website and mobile application are used across a large student base. For example, we may not be able to identify individual students who have multiple accounts from multiple students who share one account on our website or mobile application. In addition, we collect student reviews to measure student satisfaction rate and other student engagement metrics, but these reviews may not be representative of our entire student population. Errors or inaccuracies in our metrics or data could result in incorrect business decisions and inefficiencies. For instance, if a significant understatement or overstatement of student satisfaction or marketing spending were to occur, we might expend resources to implement unnecessary business measures or fail to take required actions to remedy an unfavorable trend. If investors do not perceive our operating metrics to accurately represent our operating performance, or if we discover material inaccuracies in our operating metrics, our reputation may beharmed.

If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately or timely report our results of operations or prevent fraud, and investor confidence and the market price of the ADSs may be materially and adversely affected.

We are a public company in the United States subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, requires that we include a report from management on our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report for the fiscal year ~~ending~~ended December 31, 2019. In addition, once we cease to be an “emerging growth company” as such term is defined in the JOBS Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, as we are a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future and we may be unable to timely complete our evaluation testing and any required remediation.

During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404, we may identify weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. Generally speaking, if we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of the ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We ~~will incur~~have incurred increased costs as a result of being a public company, particularly after we cease to qualify as an “emerging growth company.”

We are a public company and expect to continue to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and the New York Stock Exchange, impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an “emerging growth company” pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, in the assessment of the emerging growth company’s internal control over financial reporting. The JOBS Act also permits an emerging growth company to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

We expect these rules and regulations to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly. After we are no longer an “emerging growth company,” we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 and the other rules and regulations of the SEC. For example, as a result of becoming a public company, we have appointed independent directors and adopted policies regarding internal controls and disclosure controls and procedures. We also expect that operating as a public company ~~will make~~also makes it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. In addition, we will incur additional costs associated with our public company reporting requirements. It may also be more difficult for us to find qualified persons to serve on our Board of Directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with any degree of certainty the amount of additional costs we may incur or the timing of suchcosts.

We have granted, and may continue to grant, share incentives, which may result in increased share based compensation expenses.

We adopted an equity incentive plan in October 2017, or the 2017 Plan, for the purpose of granting share based compensation awards to employees, officers, directors and consultants to incentivize their performance and promote the success of our business.

We account for compensation costs for all share-based awards using a fair-value based method and recognize expenses in our consolidated statements of operations in accordance with U.S. GAAP. Under the 2017 Plan, we are authorized to grant options, restricted stock units and other types of awards the administrator of the 2017 Plan decides. Under the 2017 Plan, the maximum aggregate number of shares which may be issued pursuant to all awards is 829,349 shares. As of the date of this annual report, options to purchase a total of ~~50,206~~35,433 ordinary shares were outstanding under the 2017 Plan. All of the ordinary shares reserved and issuable upon the exercise of options granted pursuant to the 2017 Plan shall, upon issuance of such ordinary shares, be designated as Class C ordinary shares. We believe the granting of share-based awards is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based awards in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

Failure to make adequate contributions to various employee benefits plans as required by PRC regulations may subject us to penalties.

Companies operating in China are required to participate in various government-sponsored employee benefit plans, including certain social insurance, housing funds and other welfare-oriented payment obligations, and contribute to the plans in amounts equal to certain percentages of salaries, including bonuses and allowances, of employees up to a maximum amount specified by the local government from time to time at locations where our employees are based. The requirement of employee benefit plans has not been implemented consistently by the local governments in China given the different levels of economic development in different locations. Our failure in making contributions to various employee benefit plans and in complying with applicable PRC labor-related laws may subject us to late payment penalties, and we could be required to make up the contributions for these plans as well as to pay late fees and fines. If we are subject to late fees or fines in relation to the underpaid employee benefits, our financial condition and results of operations may be adversely affected. In addition, to the extent that we can make a reasonable estimate of the liability arising from our failure in making full contributions to various employee benefit plans, we record a related contingent liability. However, the amount of our estimates may be inaccurate, in which case our financial condition and cash flow may be adversely affected if we were to pay late fees or fines in relation to the underpaid employeebenefits.

Increases in labor costs in the PRC may adversely affect our business and results of operations.

The currently effective PRC Labor Contract Law was first adopted on June 29, 2007 and later amended on December 28, 2012. The PRC Labor Contract Law has reinforced the protection of employees who, under the PRC Labor Contract Law, have the right, among others, to have written employment contracts, to enter into employment contracts with no fixed term under certain circumstances, to receive overtime wages and to terminate or alter terms in labor contracts. Furthermore, the PRC Labor Contract Law sets forth additional restrictions and increases the costs involved with dismissing employees. To the extent that we need to significantly reduce our workforce, the PRC Labor Contract Law could adversely affect our ability to do so in a timely and cost-effective manner, and our results of operations could be adversely affected. In addition, for employees whose employment contracts include noncompetition terms, the PRC Labor Contract Law requires us to pay monthly compensation after such employment is terminated, which will increase our operating expenses.

In addition, we are required by PRC laws and regulations to make social insurance registration and open housing fund account with relevant governmental authorities and pay various statutory employee benefits, including pensions, housing fund, medical insurance, work-related injury insurance, unemployment insurance and maternity insurance to designated government agencies for the benefit of our employees. The relevant government agencies may examine whether an employer has made adequate payments of the requisite statutory employee benefits, and those employers who fail to make adequate payments may be subject to late payment fees, fines and/or other penalties. If we fail to make adequate social insurance and housing fund contributions, we may be subject to fines and legal sanctions, and our business, financial condition and results of operations may be adversely affected. We expect that our labor costs, including wages and employee benefits, will continue to increase. Unless we are able to pass on these increased labor costs to our customers by increasing the prices of our products and services, our financial conditions and results of operations would be materially and adversely affected.

We lease real properties from third parties primarily for our office use in China, and the lease agreements for most of these leased properties have not been registered with the PRC governmental authorities as required by PRC law. Although the failure to do so does not in itself invalidate the leases, we may be ordered by the PRC government authorities to rectify such noncompliance and, if such noncompliance were not rectified within a given period of time, we may be subject to fines imposed by PRC government authorities ranging from RMB1,000 and RMB10,000 for ~~approximately 118 of~~ our lease agreements that have not been registered with the relevant PRC governmental authorities.

As of the date of this annual report, we are not aware of any regulatory or governmental actions, claims or investigations being contemplated or any challenges by third parties to our use of our leased properties the lease agreements of which have not been registered with the government authorities. However, we cannot assure you that the government authorities will not ~~imposed~~impose fines on us due to our failure to register any of our lease agreements, which may negatively impact our financial condition.

We lease real properties from third parties in China for marketing and providing offline consultation related to our online services for potential students or existing students. Some of the ownership certificates or other similar proof of certain leased properties have not been provided to us by the relevant lessors. Therefore, we cannot assure you that such lessors are entitled to lease the relevant real properties to us. If the lessors are not entitled to lease the real properties to us and the owners of such real properties decline to ratify the lease agreements between us and the respective lessors, we may not be able to enforce our rights to lease such properties under the respective lease agreements against the owners. As of the date of this annual report, we are not aware of any claim or challenge brought by any third parties concerning the use of our leased properties without obtaining proper ownership proof. If our lease agreements are claimed as null and void by third parties who are the real owners of such leased real properties, we could be required to vacate the properties, in the event of which we could only initiate the claim against the lessors under relevant lease agreements for indemnities for their breach of the relevant leasing agreements. We cannot assure you that suitable alternative locations are readily available on commercially reasonable terms, or at all, and if we are unable to relocate our operations in a timely manner, our operations may be interrupted.

Our operations depend on the performance of the internet infrastructure and telecommunications networks in China.

The successful operation of our business depends on the performance of the internet infrastructure and telecommunications networks in China. Almost all access to the internet is maintained through state-owned telecommunications operators under the administrative control and regulatory supervision of the MIIT. Moreover, we have entered into contracts with various subsidiaries of a limited number of telecommunications service providers at provincial level and rely on them to provide us with data communications capacity through local telecommunications lines. We have limited access to alternative networks or services in the event of disruptions, failures or other problems with China’s internet infrastructure or the telecommunications networks provided by telecommunications service providers. Our platform regularly serves a large number of users and advertisers. With the expansion of our business, we may be required to upgrade our technology andinfrastructure to keep up with the increasing traffic on our platform. However, we have no control over the costs of the services provided by telecommunications service providers. If the prices we pay for telecommunications and internet services rise significantly, our results of operations may be materially and adversely affected. If internet access fees or other charges to internet users increase, our user traffic may decline and our business may be harmed.

We and certain of our directors and officers have been named as defendants in several shareholder class action lawsuits, which could have a material adverse impact on our business, financial condition, results of operation, cash flows and reputation.

We will have to defend against the class actions described in “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings,” including any appeals of such lawsuits should our initial defense be unsuccessful. We are currently unable to estimate the potential loss, if any, associated with the resolution of such lawsuit. We cannot guarantee that we will not be a target for lawsuits in the future, including putative class action lawsuits brought by shareholders. There can be no assurance that we will be able to prevail in our defense or reverse any unfavorable judgment on appeal, and we may decide to settle lawsuits on unfavorable terms. Any adverse outcome of these cases, including any plaintiffs’ appeal of the judgment in these cases, could result in payments of substantial monetary damages or fines, or changes to our business practices, and thus have a material adverse effect on our business, financial condition, results of operation, cash flows and reputation. In addition, there can be no assurance that our insurance carriers will cover all or part of the defense costs, or any liabilities that may arise from these matters. The litigation process may utilize a significant portion of our cash resources and divert management’s attention from the day-to-day operations of our company, all of which

could harm our business. We also may be subject to claims for indemnification related to these matters, and we cannot predict the impact that indemnification claims may have on our business or financial results.

Insurance companies in China currently do not offer as extensive an array of insurance products as insurance companies in more developed economies. Currently, we do not have any business liability or disruption insurance to cover our operations. We have determined that the costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us to have such insurance. Any uninsured business disruptions may result in our incurring substantial costs and the diversion of resources, which could have an adverse effect on our results of operations and financial condition.

We face risks related to natural disasters, extreme weather conditions, health epidemics and other catastrophic incidents, which could significantly disrupt our operations.

China has in the past experienced significant natural disasters, including earthquakes, extreme weather conditions, as well as health scares related to epidemic diseases, and any similar event could materially impact our business in the future. If a disaster or other disruption were to occur in the future that affects the regions where we operate our business, our operations could be materially and adversely affected due to loss of personnel and damages to property. Even if we are not directly affected, such a disaster or disruption could affect the operations or financial condition of our ecosystem participants, which could harm our results ofoperations.

In addition, accidents, disasters and public health challenges in China and globally could impact our business and results of operations. These types of events could benegatively impact user activity and our local operations, if any, in the affected ~~by public health epidemics, such as~~regions, or, depending upon the severity, across China or globally, which could adversely impact our business and results of operations. For example, the outbreak of ~~avian influenza, severe acute respiratory syndrome,~~coronavirus, or ~~SARS, Zika virus, Ebola virus or other disease. If any~~COVID-19, had caused temporary interruptions to the learning activities of our employees is suspected of having contracted a contagious disease, we may be required to apply quarantines or suspend our operations. Furthermore, any future outbreak may restrict economic activities in affected regions, resulting in reduced business volume, temporary closurestudents and operations of our ~~offices or otherwise disrupt~~business partners and negatively affected certain aspects of our business operations in 2020. For example, the Self-taught Higher Education Examination, or the STE, a state-administered exam in China for learners pursuing associate diplomas or bachelor’s degrees, was postponed by the Ministry of Education of the PRC as a result of the COVID-19 pandemic, resulting in fluctuations in enrollments for our STE courses which have historically represented a significant portion of our net revenues, gross billings and new student enrollments of our online course offerings. We have taken precautionary measures intended to minimize the risks of COVID-19 to our students, employees, teachers, mentors and business partners, including temporarily requiring our employees to work remotely or canceling or postponing sponsored offline events and activities, which could compromise our efficiency and productivity during such periods, require us to incur additional costs, slow down our branding and marketing efforts, and result in fluctuations in our results of operations. While the foregoing restrictions and measures have been eased and our business operations have been recovered, our results of operations may be adversely affected to the extent that COVID-19 continues to affect the Chinese economy in general. Additionally, as COVID-19 continues to evolve into a worldwide health crisis that could adversely affect the economies and financial markets of countries other than China, it may potentially result in an economic downturn that could affect demand for our users, business partners and services and therefore materially adversely affect our business, financial condition and results of operations. Furthermore, to the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this section entitled “Item 3. Key Information—3.D. Risk Factors,” such as those relating to our ability to improve or expand our product and service offerings, and to retain existing or attract new advertising customers, among other things.

If the PRC government finds that the agreements that establish the structure for operating some of our operations in China do not comply with PRC regulations relating to the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

Foreign investment in the value-added telecommunication services industry in China is extensively regulated and subject to numerous restrictions. Pursuant to the list of special management measures for the market entry of foreign investment, or the Negative List, published by the National Development and Reform Commission and the Ministry of Commerce on June ~~28, 2018~~23, 2020 and effective on July ~~28, 2018,~~23, 2020, with a few exceptions, foreign investors are not allowed to own more than 50% of the equity interests in a value-added telecommunication service ~~provider and~~provider. Specifically, any ~~such~~ foreign investor must have experience in providing value-added telecommunications services overseas and maintain a good track record.

We are a Cayman Islands company and our wholly-owned PRC subsidiaries are currently considered foreign-invested enterprise. Accordingly, our PRC subsidiaries are not eligible to provide value-added telecommunication services in China. To ensure strict compliance with the PRC laws and regulations, we conduct such business activities through ~~Beijing Sunlands and Tianjin Shangde,~~ our consolidated variable interest entities, or our VIEs, and their respective subsidiaries. Our wholly owned subsidiaries in China have entered into a series of contractual arrangements with our VIEs, their respective shareholders and their respective subsidiaries, which enable us to (i)exercise effective control over our VIEs, (ii) receive substantially all of the economic benefits of our VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests and assets in our VIEs when and to the extent permitted by PRC law. As a result of these contractual arrangements, we have control over and are the primary beneficiary of our VIEs and hence consolidate its financial results as our VIEs under U.S. GAAP. See “Item 4. Information of the Company— ~~Item~~ 4.C. Organizational Structure” for further details.

It is uncertain whether any new PRC laws, rules or regulations relating to variable interest entity structures will be adopted or if adopted, what they would provide. In particular, the ~~draft Implementation Rules~~MOJ Draft provide that, among other things, entities implementing group-based education shall not control non-profit schools by merger, acquisition, franchise or contractual arrangements. The ~~draft Implementation Rules~~MOJ Draft also provide that transactions among private schools and their affiliates shall be fair and open to public, for those agreements entered into by non-profit schools and their affiliates which is long-term or involving important interests or repeated performance, the educational authorities shall audit the necessity, legitimacy and compliance of such agreements. As of the date of this annual report, two of our schools are privately run non-enterprise institution and have not made the election to be registered as a for-profit or non-profit school. We will choose to be registered as a for-profit school for such school. However, we may not be able to complete the registration in timely manner given that more specific and stringent registration requirements and guidelines are expected to be introduced by the competent local authorities. Otherwise, the validity and enforceability of our contractual arrangements may be challenged. It is uncertain when the ~~draft~~MOJ Draft would be signed into law and whether the final version would have any substantial changes from the draft.

If the PRC government finds that our contractual arrangements do not comply with its restrictions on foreign investment in the value-added telecommunication services, or if the PRC government otherwise finds that we, our VIEs, or any of its subsidiaries are in violation of PRC laws or regulations or lack the necessary permits or licenses to operate our business, the relevant PRC regulatory authorities, including the MIIT and ~~SAIC,~~SAMR, would have broad discretion in dealing with such violations or failures, including, without limitation:

Any of these actions could cause significant disruption to our business operations and severely damage our reputation, which would in turn materially and adversely affect our business, financial condition and results of operations. If any of these occurrences results in our inability to direct the activities of our VIEs that most significantly impact its economic performance and/or our failure to receive the economic benefits from our VIEs, we may not be able to consolidate the entity in our consolidated financial statements in accordance with GAAP.

We rely on contractual arrangements with our VIEs and their respective shareholders for a large portion of our business operations which may not be as effective as direct ownership in providing operational control.

We have relied and expect to continue to rely on contractual arrangements with ~~Beijing Sunlands and Tianjin Shangde, or~~ our VIEs, their respective shareholders and their respective subsidiaries to operate our online education services business in China. These contractual arrangements may not be as effective as direct ownership in providing us with control over our VIEs. For example, our VIEs and their respective shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. The revenues contributed by our VIEs and their respective subsidiaries constituted substantially all of our net revenues in ~~2016, 2017~~2018 and ~~2018.~~2019, and approximately 50% in 2020.

If we had direct ownership of our VIEs, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of our VIEs, which in turn could implement changes, subject to any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by our VIEs and their respective shareholders of their obligations under the contracts to exercise control over our VIEs. The shareholders of our consolidated VIEs may not act in the best interests of our company or may not perform their obligations under these contracts. Such risks exist throughout the period in which we intend to operate certain portions of our business through the contractual arrangements with our VIEs. If any disputes relating to these contracts remain unresolved, we will have to enforce our rights under these contracts through the operations of PRC law and arbitration, litigation and other legal proceedings and therefore will be subject to uncertainties in the PRC legal system. Therefore, our contractual arrangements with our VIEs may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

Any failure by our VIEs or their respective shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on our business.

If our VIEs or their respective shareholders fail to perform their respective obligations under the contractual arrangements, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and claiming damages, which we cannot assure will be effective under PRC law. For example, if the shareholders of our VIEs refuse to transfer their equity interest in our VIEs to us or our designee if we exercise the purchase option pursuant to these contractual arrangements, or if they otherwise act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations. In addition, if any third parties claim any interest in such shareholders’ equity interests in our VIEs, our ability to exercise shareholders’ rights or foreclose the share pledge according to the contractual arrangements may be impaired. If these or other disputes between the shareholders of our VIEs and third parties were to impair our control over our VIEs, our ability to consolidate the financial results of our VIEs would be affected, which would in turn result in a material adverse effect on our business, operations and financial condition.

Our contractual arrangements are governed by PRC law. Accordingly, these contracts would be interpreted in accordance with PRC law, and any disputes would be resolved in accordance with PRC legal procedures.

The legal system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. Meanwhile, there are very few precedents and little formal guidance as to how contractual arrangements in the context of a VIE should be interpreted or enforced under PRC law. There remain significant uncertainties regarding the ultimate outcome of such arbitration should legal action become necessary. In addition, under PRC law, rulings by arbitrators are final, parties cannot appeal the arbitration results in courts, and if the losing parties fail to carry out the arbitration awards within a prescribed time limit, the prevailing parties may only enforce the arbitration awards in PRC courts, which would require additional expenses and delay. In the event we are unable to enforce these contractual arrangements, or if we suffer significant delays or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over our VIEs, and our ability to conduct our business may be negatively affected.

The shareholders of our VIEs may have actual or potential conflicts of interest with us, which may materially and adversely affect our business and financial condition.

The shareholders of our VIEs may have actual or potential conflicts of interest with us. These shareholders may refuse to sign or breach, or cause our VIEs to breach, or refuse to renew, the existing contractual arrangements we have with them and our VIEs, which would have a material and adverse effect on our ability to effectively control our VIEs and receive economic benefits from it. For example, the shareholders may be able to cause our agreements with our VIEs to be performed in a manner adverse to us by, among other things, failing to remit payments due under the contractual arrangements to us on a timely basis. We cannot assure you that when conflicts of interest arise any or all of these shareholders will act in the best interests of our company or such conflicts will be resolved in our favor. Currently, we do not have any arrangements to address potential conflicts of interest between these shareholders and our company. If we cannot resolve any conflict of interest or dispute between us and these shareholders, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

Contractual arrangements in relation to our VIEs may be subject to scrutiny by the PRC tax authorities and they may determine that we or our VIEs owe additional taxes, which could negatively affect our financial condition and the value of your investment.

Under applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities within ten years after the taxable year when the transactions are conducted. We could face material and adverse tax consequences if the PRC tax authorities determine that the VIE contractual arrangements were not entered into on an arm’s-length basis in such a way as to result in an impermissible reduction in taxes under applicable PRC laws, rules and regulations, and adjust the income of our VIEs in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction of expense deductions recorded by our VIEs for PRC tax purposes, which could in turn increase its tax liabilities without reducing our PRC subsidiary’s tax expenses. In addition, the PRC tax authorities may impose late payment fees and other penalties on our VIEs for the adjusted but unpaid taxes according to the applicable regulations. Our financial position could be materially and adversely affected if our VIEs’ tax liabilities increase or if it is required to pay late payment fees and other penalties.

We may lose the ability to use, or otherwise benefit from, the licenses, approvals and assets held by our VIEs, which could severely disrupt our business, render us unable to conduct some or all of our business operations and constrain our growth.

As part of our contractual arrangements with our VIEs, our VIEs hold certain assets, licenses and permits that are material to our business operations, such as the ICP License and the License for the Production and Operation of Radio and Television Program. The contractual arrangements contain terms that specifically obligate VIEs’ shareholders to ensure the valid existence of the VIEs and restrict the disposal of material assets of the VIEs. However, in the event ~~the~~our VIEs’ shareholders breach the terms of these contractual arrangements and voluntarily liquidate our VIEs, or our VIEs declares bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, or are otherwise disposed of without our consent, we may be unable to conduct some or all of our business operations or otherwise benefit from the assets held by ~~the~~our VIEs, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, if our VIEs undergo a voluntary or involuntary liquidation proceeding, its shareholders or unrelated third-party creditors may claim rights to some or all of the assets of the VIEs, thereby hindering our ability to operate our business as well as constrain our growth.

Certain of our existing shareholders have substantial influence over our company, and their interests may not be aligned with the interests of our other stockholders.

Mr. Peng Ou, our founder and the chairman of our Board of Directors, owns approximately ~~54.3%~~56.1% of our voting power and Mr. Tongbo Liu, our director and our Chief Executive Officer, owns approximately ~~21.0%~~21.2% of our voting power as of the date of this annual report. In addition, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees collectively beneficially own all of our issued and outstanding Class C ordinary shares which constitute approximately ~~85.0%~~84.3% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. In addition, up to ~~414,393~~429,169 ordinary shares reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. See “—Risks Related to the ADSs—Our triple-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.” As a result, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may also have the effect of discouraging, delaying or preventing a future change of control, which could deprive our stockholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of theADSs.

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

Substantially all of our assets and operations are located in China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China’s economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Meanwhile, economic conditions in China are sensitive to global economic conditions, changes in domestic economic and political policies and the expected or perceived overall economic growth rate in China. There have been concerns over the relationship among China and other Asian countries, which may result in or intensify potential conflicts in relation to territorial disputes, and the trade disputes between the United States and China. It is unclear whether these challenges and uncertainties will be contained or resolved, and what effects they may have on the global political and economic conditions in the long term.

While the Chinese economy has experienced significant growth over past decades, growth has been uneven, both geographically and among various sectors of the economy. Any adverse changes in economic conditions in China, in the policies of the Chinese government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to a reduction in demand for our services and adversely affect our competitive position. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate adjustment, to control the pace of economic growth. These measures may cause decreased economic activity in China, which may adversely affect our business and operatingresults.

The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions under the civil law system may be cited for reference but have limited precedential value.

In 1979, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation over the past three decades has significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, the interpretation and enforcement of these laws and regulations involve uncertainties. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us.

Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.

You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against us or our management named in the annual report based on foreign laws.

We are an exempted company incorporated under the laws of the Cayman Islands, we conduct substantially all of our operations in China, and substantially all of our assets are located in China. In addition, all our senior executive officers reside within China for a significant portion of the time and most are PRC nationals. As a result, it may be difficult for our shareholders to effect service of process upon us or those persons inside China. In addition, China does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts with the Cayman Islands and many other countries and regions. Therefore, recognition and enforcement in China of judgments of a court in any of these non-PRC jurisdictions in relation to any matter not subject to a binding arbitration provision may be difficult or impossible.

We may rely on dividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our PRC subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.

We are a Cayman Islands holding company and we rely principally on dividends and other distributions on equity from our PRC subsidiaries for our cash requirements, including for services of any debt we may incur. Our PRC subsidiary’s ability to distribute dividends is based upon its distributable earnings. Current PRC regulations permit our PRC subsidiaries to pay dividends to its respective shareholders only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, each of our PRC subsidiary, our VIEs and their respective subsidiaries are required to set aside at least 10% of its after-tax profits each year, if any, to fund a statutory reserve until such reserve reaches 50% of its registered capital. Each of our PRC subsidiaries as a Foreign Invested Enterprise, or FIE, is also required to further set aside a portion of its after-tax profits to fund the employee welfare fund, although the amount to be set aside, if any, is determined at its discretion. These reserves are not distributable as cash dividends. If our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Any limitation on the ability of our PRC subsidiaries to distribute dividends or other payments to their respective shareholders could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our businesses, pay dividends or otherwise fund and conduct our business.

To address the persistent capital outflow and the RMB’s depreciation against the U.S. dollar in the fourth quarter of 2016, the People’s Bank of China and the State Administration of Foreign Exchange, or SAFE, implemented a series of capital control measures in the subsequent months, including stricter vetting procedures for China-based companies to remit foreign currency for overseas acquisitions, dividend payments and shareholder loan repayments. For instance, the Circular on Promoting the Reform of Foreign Exchange Management and Improving Authenticity and Compliance Review, or the SAFE Circular 3, issued on January 26, 2017, provides that the banks shall, when dealing with dividend remittance transactions from domestic enterprise to its offshore shareholders of more than US$50,000, review the relevant board resolutions, original tax filing form and audited financial statements of such domestic enterprise based on the principal of genuine transaction. The PRC government may continue to strengthen its capital controls and our PRC subsidiaries’ dividends and other distributions may be subject to tightened scrutiny in the future. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

In addition, the Enterprise Income Tax Law and its implementation rules provide that a withholding tax rate of up to 10% will be applicable to dividends payable by Chinese companies to non-PRC-resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRC central government and governments of other countries or regions where the non-PRC resident enterprises are incorporated.

The custodians or authorized users of our controlling non-tangible assets, including chops and seals, may fail to fulfill their responsibilities, or misappropriate or misuse these assets.

Under the PRC law, legal documents for corporate transactions, including agreements and contracts are executed using the chop or seal of the signing entity or with the signature of a legal representative whose designation is registered and filed with relevant PRC industry and commerce authorities.

In order to secure the use of our chops and seals, we have established internal control procedures and rules for using these chops and seals. In any event that the chops and seals are intended to be used, the responsible personnel will submit the application through our office automation system and the application will be verified and approved by authorized employees in accordance with our internal control procedures and rules. In addition, in order to maintain the physical security of our chops, we generally have them stored in secured locations accessible only to authorized employees. Although we monitor such authorized employees, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our employees could abuse their authority, for example, by entering into a contract not approved by us or seeking to gain control of one of our subsidiaries or consolidated VIEs. If any employee obtains, misuses or misappropriates our chops and seals or other controlling non-tangible assets for whatever reason, we could experience disruption to our normal business operations. We may have to take corporate or legal action, which could involve significant time and resources to resolve and divert management from our operations.

Fluctuations in exchange rates could have a material and adverse effect on our results of operations and the value of your investment.

The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC government. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. Following the removal of the U.S. dollar peg, the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. ~~Between July 2008 and June 2010, this appreciation halted and the exchange rate between the Renminbi and the U.S. dollar remained within a narrow band.~~ Since June 2010, the Renminbi has started to appreciate slowly against the U.S. dollar, though there have been periods when the U.S. dollar has appreciated against the RMB. On August 11, 2015, the PBOC allowed the Renminbi to depreciate by approximately 2% against the U.S. dollar. Since then and until the end of 2016, the Renminbi has depreciated against the U.S. dollar by approximately 10%. It is difficult to predict how long such depreciation of RMB against the U.S. dollar may last and when and how the relationship between the RMB and the U.S. dollar may change again.

All of our revenue and substantially all of our costs are denominated in Renminbi. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant revaluation of Renminbi may materially and adversely affect our results of operations and financial position reported in Renminbi when translated into U.S. dollars, and the value of, and any dividends payable on, the ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive from the initial public offering into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount.

Governmental control of currency conversion may limit our ability to utilize our net revenues effectively and affect the value of your investment.

The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our Cayman Islands holding company primarily relies on dividend payments from our PRC subsidiaries to fund any cash and financing requirements we may have. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval of SAFE by complying with certain procedural requirements. Specifically, under the existing exchange restrictions, without prior approval of SAFE, cash generated from the operations of our PRC subsidiaries in China may be used to pay dividends to our company. However, approval from or registration with appropriate government authorities is required where Renminbi is to be converted into foreign currency and

remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. As a result, we need to obtain SAFE approval to use cash generated from the operations of our PRC subsidiaries and VIEs to pay off their respective debt in a currency other than Renminbi owed to entities outside China, or to make other capital expenditure payments outside China in a currency other than Renminbi. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of the ADSs.

Certain PRC regulations may make it more difficult for us to pursue growth through acquisitions.

Among other things, the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, adopted by six PRC regulatory agencies in 2006 and amended in 2009, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. Such regulation requires, among other things, that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor acquires control of a PRC domestic enterprise or a foreign company with substantial PRC operations, if certain thresholds under the Provisions on Thresholds for Prior Notification of Concentrations of Undertakings, issued by the State Council in 2008 and amended in 2018, are triggered. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the ~~NPC~~National People’s Congress which became effective in 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds must be cleared by the ~~MOFCOM~~relevant governmental authorities before they can be completed. On February 7, 2021, the Anti-monopoly Commission of the State Council, published the Anti-Monopoly Guidelines for the Internet Platform Economy Sector that aims at specifying some of the circumstances under which an activity of internet platforms may be identified as monopolistic act as well as setting out merger controlling filing procedures involving variable interest entities. In addition, PRC national security review rules which became effective in September 2011 require acquisitions by foreign investors of PRC companies engaged in military related or certain other industries that are crucial to national security be subject to security review before consummation of any such acquisition. The Measures for the Security Review of Foreign Investments promulgated by the National Development and Reform Commission and MOFCOM which became effective from January 2021 further requires that security review by relevant governmental authorities shall be conducted in accordance with the provisions of the Measures for foreign investments that affect or may affect national security. We may pursue potential strategic acquisitions that are complementary to our business and operations. Complying with the requirements of these regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval or clearance from the MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our marketshare.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident beneficial owners or our PRC subsidiary to liability or penalties, limit our ability to inject capital into our PRC subsidiary, limit our PRC subsidiary’s ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.

In July 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment Through Special Purpose Vehicles, or SAFE Circular 37, to replace the Notice on Relevant Issues Concerning Foreign Exchange Administration for Domestic Residents’ Financing and Roundtrip Investment Through Offshore Special Purpose Vehicles, or SAFE Circular 75, which ceased to be effective upon the promulgation of SAFE Circular 37. SAFE Circular 37 requires PRC residents (including PRC individuals and PRC corporate entities) to register with SAFE or its local branches in connection with their direct or indirect offshore investment activities. SAFE Circular 37 is applicable to our shareholders who are PRC residents and may be applicable to any offshore acquisitions that we make in the future.

Under SAFE Circular 37, PRC residents who make, or have prior to the implementation of SAFE Circular 37 made, direct or indirect investments in offshore special purpose vehicles, or SPVs, will be required to register such investments with SAFE or its local branches. In addition, any PRC resident who is a direct or indirect shareholder of an SPV is required to update its filed registration with the local branch of SAFE with respect to that SPV, to reflect any material change. Moreover, any subsidiary of such SPV in China is required to urge the PRC resident shareholders to update their registration with the local branch of SAFE. If any PRC shareholder of such SPV fails to make the required registration or to update the previously filed registration, the subsidiary of such SPV in China may be prohibited from distributing its profits or the proceeds from any capital reduction, share transfer or liquidation to the SPV, and the SPV may also be prohibited from making additional capital contributions into its subsidiary in China. On February 13, 2015, the SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which became effective on June 1, 2015. Under SAFE Notice 13, applications for foreign exchange registration of inbound foreign

direct investments and outbound overseas direct investments, including those required under SAFE Circular 37, will be filed with qualified banks instead of SAFE. The qualified banks will directly examine the applications and accept registrations under the supervision of SAFE. SAFE Notice 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead, relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

~~Most of~~We have requested our shareholders that we are aware of being subject to SAFE regulations ~~and all of these shareholders have completed~~to make all necessary registrations, filings and amendments with the local SAFE branch or qualified banks as required by SAFE Circular ~~37 as of the date of this annual report.~~37. We cannot assure you, however, that all of these individuals may continue to make required registrations, filings or updates on a timely manner, or at all. We can provide no assurance that we are or will in the future continue to be informed of identities of all PRC residents holding direct or indirect interest in our company. Any failure or inability by such individuals to comply with SAFE regulations may subject us to fines or legal sanctions, such as restrictions on our cross-border investment activities or our PRC subsidiary’s ability to distribute dividends to, or obtain foreign ~~exchange- denominated~~exchange-denominated loans from, our company or prevent us from making distributions or paying dividends. As a result, our business operations and our ability to make distributions to you could be materially and adverselyaffected.

Furthermore, as these foreign exchange regulations are still relatively new and their interpretation and implementation has been constantly evolving, it is unclear how these regulations, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

Any failure to comply with PRC regulations regarding the registration requirements for employee stock incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, replacing earlier rules promulgated in 2007. Pursuant to these rules, PRC citizens and non-PRC citizens who reside in China for a continuous period of not less than one year who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be the PRC subsidiaries of such overseas-listed company, and complete certain other procedures. In addition, an overseas-entrusted institution must be retained to handle matters in connection with the exercise or sale of stock options and the purchase or sale of shares and interests. We and our executive officers and other employees who are PRC citizens or who reside in the PRC for a continuous period of not less than one year and who have been granted options will be subject to these regulations because we are an overseas-listed company. Failure to complete the SAFE registrations may subject them to fines and legal sanctions, there may be additional restrictions on the ability of them to exercise their stock options or remit proceeds gained from sale of their stock into the PRC. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors, executive officers and employees under PRC law. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations on Foreign Exchange—Regulations on Stock IncentivePlans.”

If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.

Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside of the PRC with its “de facto management body” within the PRC is considered a “resident enterprise” and will be subject to the enterprise income tax on its global income at the rate of 25%. The implementation rules define the term “de facto management body” as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In 2009, the State Administration of Taxation, or SAT, issued a circular, known as SAT Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the SAT’s general position on how the “de facto management body” text should be applied in determining the tax resident status of all offshore enterprises. According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as

a PRC tax resident by virtue of having its “de facto management body” in China, and will be subject to PRC enterprise income tax on its global income only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in thePRC.

We believe our company is not a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” If the PRC tax authorities determine that our company is a PRC resident enterprise for enterprise income tax purposes, we will be subject to PRC enterprise income on our worldwide income at the rate of 25%. Furthermore, we be required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of the ADSs. In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in the ADSs or ordinary shares.

We face uncertainty with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies.

On February 3, 2015, the SAT issued the Public Notice Regarding Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-Tax Resident Enterprises, or SAT Bulletin 7. SAT Bulletin 7 extends its tax jurisdiction to transactions involving the transfer of taxable assets through offshore transfer of a foreign intermediate holding company. In addition, SAT Bulletin 7 has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. SAT Bulletin 7 also brings challenges to both foreign transferor and transferee (or other person who is obligated to pay for the transfer) of taxable assets.

On October 17, 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or SAT Bulletin 37, which came into effect on December 1, 2017. The SAT Bulletin 37 further clarifies the practice and procedure of the withholding of non-resident enterprise income tax.

Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which is an Indirect Transfer, the non-resident enterprise as either transferor or transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority. Using a “substance over form” principle, the PRC tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring PRC tax. As a result, gains derived from such Indirect Transfer may be subject to PRC enterprise income tax, and the transferee or other person who is obligated to pay for the transfer is obligated to withhold the applicable taxes, currently at a rate of 10% for the transfer of equity interests in a PRC resident enterprise. Both the transferor and the transferee may be subject to penalties under PRC tax laws if the transferee fails to withhold the taxes and the transferor fails to pay the taxes.

We face uncertainties as to the reporting and other implications of certain past and future transactions where PRC taxable assets are involved, such as offshore restructuring, sale of the shares in our offshore subsidiaries and investments. Our company may be subject to filing obligations or taxed if our company is transferor in such transactions, and may be subject to withholding obligations if our company is transferee in such transactions, under SAT Bulletin 7 and/or SAT Bulletin 37. For transfer of shares in our company by investors who are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist in the filing under SAT Bulletin 7 and/or SAT Bulletin 37. As a result, we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to request the relevant transferors from whom we purchase taxable assets to comply with these circulars, or to establish that our company should not be taxed under these circulars, which may have a material adverse effect on our financial condition and results of operations.

Uncertainties exist with respect to the interpretation and implementation of the newly enacted Foreign Investment Law and how it may impact our business, financial condition and results of operations.

On March 15, 2019, the National People’s Congress promulgated the Foreign Investment Law, which ~~will come~~came into effect on January 1, 2020 and ~~replace~~replaced the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The enacted Foreign Investment Law does not touch upon the relevant concepts and regulatory regimes of “actual control” in determining whether a company is considered a foreign invested enterprise, and thus this regulatory topic remains unclear under the Foreign Investment Law. On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the Foreign Investment Law. However, since ~~it is~~the Foreign Investment Law and the Implementation Rules of Foreign Investment Law are relatively new, uncertainties still exist in relation to its interpretation and implementation. For instance, though the Foreign Investment Law does not explicitly classify contractual arrangements as a form of foreign investment, it contains a catch-all provision under the definition of “foreign investment,” which includes investments made by foreign investors in China through means stipulated in laws or administrative regulations or other methods prescribed by the State Council. Therefore, it still leaves leeway for future laws, administrative regulations or provisions promulgated by the State Council to provide for contractual arrangements as a form of foreign investment. Furthermore, if future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be taken by companies with respect to existing contractual arrangements, such as unwinding our existing contractual arrangements and/or disposal of our related business operations, we may face substantial uncertainties as to whether we can complete such actions in a timely manner, or at all. Failure to take timely and appropriate measures to cope with any of these or similar regulatory compliance challenges could materially and adversely affect our current corporate structure, financial condition and business operations.

The Holding Foreign Companies Accountable Act, or the HFCA Act, was enacted on December 18, 2020. The HFCA Act states if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection by the PCAOB for three consecutive years beginning in 2021, the SEC shall prohibit our shares or ADSs from being traded on a national securities exchange or in the over the counter trading market in the U.S. Our auditor, the independent registered public accounting firm that issues the audit ~~reports~~report included elsewhere in this annual report, ~~filed with the SEC,~~ as an auditor of companies that are traded publicly in the United States and a firm registered with the ~~U.S. Public Company Accounting Oversight Board, or the~~ PCAOB, is subject to ~~the~~ laws in the United States pursuant to which the PCAOB conducts regular inspections ~~by the PCAOB~~ to assess its compliance with the applicable professional standards. Since our ~~auditors are~~auditor is located in China, a jurisdiction where the PCAOB ~~is currently~~has been unable to conduct inspections without the approval of the Chinese authorities, our ~~auditors are~~auditor is currently not ~~currently~~ inspected by the PCAOB.

On ~~May~~March 24, ~~2013,~~2021, the SEC adopted interim final rules relating to the implementation of certain disclosure and documentation requirement of the HFCA Act. We will be required to comply with these rules if the SEC identifies us as having a “non-inspection” year under a process to be subsequently established by the SEC. The SEC is assessing how to implement other requirements of the HFCA Act, including the listing and trading prohibition requirements described above.

The SEC may propose additional rules or guidance that could impact us if our auditor is not subject to PCAOB inspection. For example, on August 6, 2020, the President’s Working Group on Financial Markets, or the PWG, issued the Report on Protecting United States Investors from Significant Risks from Chinese Companies to the then President of the United States. This report recommended the SEC implement five recommendations to address companies from jurisdictions that do not provide the PCAOB with sufficient access to fulfil its statutory mandate. Some of the concepts of these recommendations were implemented with the enactment of the HFCA Act. However, some of the recommendations were more stringent than the HFCA Act. For example, if a company was not subject to PCAOB inspection, the report recommended that the transition period before a company would be delisted would end on January 1, 2022.

The SEC has announced that ~~it had entered into~~the SEC staff is preparing a ~~Memorandum~~consolidated proposal for the rules regarding the implementation of ~~Understanding~~the HFCA Act to address the recommendations in the PWG report. It is unclear when the SEC will complete its rulemaking and when such rules will become effective and what, if any, of the PWG recommendations will be adopted. The implications of this possible regulation in addition to the requirements of the HFCA Act are uncertain. Such uncertainty could cause the market price of our ADSs to be materially and adversely affected, and our securities could be delisted or prohibited from being traded "over-the-counter" earlier than would be required by the HFCA Act. If our securities

are unable to be listed on ~~Enforcement Cooperation with the China Securities Regulatory Commission,~~another securities exchange by then, such a delisting would substantially impair your ability to sell or ~~the CSRC,~~purchase our ADSs when you wish to do so, and the ~~Ministry of Finance which establishes~~risk and uncertainty associated with a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations in the United States and China. It appears that the PCAOB continues to be in discussions with the Chinese regulators to permit inspections of audit firms that are registered with PCAOB in relation to the audit of Chinese companies that trade on U.S. exchanges. On December 7, 2018, the SEC and the PCAOB issuedpotential delisting would have a joint statement highlighting continued challenges faced by the U.S. regulators in their oversight of financial statement audits of U.S.-listed companies with significant operations in China. The joint statement reflects a heightened interest in this issue. However, it remains unclear what further actions the SEC and PCAOB will take and itsnegative impact on ~~Chinese companies listed~~the price of our ADSs.

The PCAOB’s inability to conduct inspections in China prevents it from fully evaluating the ~~U.S.~~

~~Inspections of other firms that the PCAOB has conducted outside of China have identified deficiencies in those firms’ audit procedures~~audits and quality control procedures ~~which may be addressed as part~~ of ~~the inspection process to improve future audit quality. The lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating~~ our ~~auditor’ audits and its quality control procedures.~~independent registered public accounting firm. As a result, we and investors ~~may be~~in our ordinary shares are deprived of the benefits of such PCAOB inspections.

The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our ~~auditors’~~independent registered public accounting firm’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to the PCAOB ~~inspections. Investors may~~inspections, which could cause investors and potential investors in our stock to lose confidence in ~~our~~audit procedures and reported financial information ~~and procedures~~ and the quality of our financial statements.

In May 2013, the PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the CSRC and the PRC Ministry of Finance, which establishes a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations undertaken by the PCAOB in the PRC or by the CSRC or the PRC Ministry of Finance in the United States. The PCAOB continues to be in discussions with the CSRC and the PRC Ministry of Finance to permit joint inspections in the PRC of audit firms that are registered with the PCAOB and audit Chinese companies that trade on U.S. exchanges.

Proceedings instituted by the SEC against Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

Starting in 2011 the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S.-listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law, they could not respond directly to the U.S. regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC.

In late 2012, this impasse led the SEC to commence administrative proceedings under Rule 102E of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese accounting firms, including our independent registered public accounting firm. A first instance trial of the proceedings in July 2013 in the SEC’s internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepted that future requests by the SEC for the production of documents would normally be made to the CSRC. The firms would receive matching Section 106 requests, and would be required to abide by a detailed set of procedures with respect to such requests, which in substance would require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or, in extreme cases, the resumption of the current proceeding against all four firms. If additional remedial measures are imposed on the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging the firms’ failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice at the end of four years starting from the settlement date, which was on February 6, 2019. Despite the final ending of the proceedings, the presumption is that all parties will continue to apply the same procedures, i.e. the SEC will continue to make its requests for the production of documents to the CSRC, and the CSRC will normally process those requests applying the sanitization procedure. We cannot predict whether, in cases where the CSRC does not authorize production of requested documents to the SEC, the SEC will further challenge the four PRC-based accounting firms’ compliance with U.S. law. If additional challenges are imposed on the Chinese affiliates of the “big four” accounting firms, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, U.S.-listed companies, and the market price of our ordinary shares may be adversely affected.

If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of the ADSs from the New York Stock Exchange or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of the ADSs in the United States.

Regulation and censorship of information disseminated over the internet in China may adversely affect our business and reputation and subject us to liability for information displayed on our website.

The PRC government has adopted regulations governing internet access and the distribution of news and other information over the internet. Under these regulations, internet content providers and internet publishers are prohibited from posting or displaying over the internet content that, among other things, violates PRC laws and regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defamatory. Failure to comply with these requirements may result in the revocation of licenses to provide internet content and other licenses, and the closure of the concerned websites. The website operator may also be held liable for such censored information displayed on or linked to the websites. If our website is found to be in violation of any such requirements, we may be penalized by relevant authorities, and our operations or reputation could be adverselyaffected.

It may be difficult for overseas regulators to conduct investigation or collect evidence within China.

Shareholder claims or regulatory investigation that are common in the United States generally are difficult to pursue as a matter of law or practicality in China. For example, in China, there are significant legal and other obstacles to providing information needed for regulatory investigations or litigation initiated outside China. Although the authorities in China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such cooperation with the securities regulatory authorities in the Unities States may not be efficient in the absence of mutual and practical cooperation mechanism. Furthermore, Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, prohibits, without the approval of the securities regulatory authority in China, (i) foreign securities regulators from engaging in any inspection activities within China and (ii) anyone from providing any documents or materials relating to capital markets activities to foreign parties. While detailed interpretation of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigation or evidence collection activities within China may further increase difficulties faced by you in protecting your interests. See also “You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law” for risks associated with investing in us as a Cayman Islands company.

The trading price of the ADSs is likely to be volatile, which could result in substantial losses to investors.

The trading price of the ADSs is likely to be volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, including the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. In addition to market and industry factors, the price and trading volume for the ADSs may be highly volatile for factors specific to our own operations, including thefollowing:

In the past, shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in a class action suit, it could divert a significant amount of our management’s attention and other resources from our business and operations and require us to incur significant expenses to defend the suit, which could harm our results of operations. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and results ofoperations.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline.

The trading market for the ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume for the ADSs to decline.

The sale or availability for sale of substantial amounts of ADSs could adversely affect their market price.

Sales of substantial amounts of the ADSs in the public market, or the perception that these sales could occur, could adversely affect the market price of the ADSs and could materially impair our ability to raise capital through equity offerings in the future. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of the ADSs.

Techniques employed by short sellers may drive down the market price of the ADSs.

Short selling is the practice of selling securities that the seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than it received in the sale. As it is in the short seller’s interest for the price of the security to decline, many short sellers publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business prospects in order to create negative market momentum and generate profits for themselves after selling a security short. These short attacks have, in the past, led to selling of shares in the market.

Public companies that have substantially all of their operations in China have been the subject of short selling. Much of the scrutiny and negative publicity has centered on allegations of a lack of effective internal control over financial reporting resulting in financial and accounting irregularities and mistakes, inadequate corporate governance policies or a lack of adherence thereto and, in many cases, allegations of fraud. As a result, many of these companies are now conducting internal

and external investigations into the allegations and, in the interim, are subject to shareholder lawsuits and/or enforcement actions by the SEC ~~enforcement actions.~~or other U.S. authorities..

It is not clear what effect such negative publicity could have on us. If we were to become the subject of any unfavorable allegations, whether such allegations are proven to be true or untrue, we could have to expend a significant amount of resources to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which we can proceed against the relevant short seller by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could distract our management from growing our business. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact our business operations, and any investment in the ADSs could be greatly reduced or even rendered worthless.

Because we do not expect to pay dividends in the foreseeable future, you must rely on a price appreciation of the ADSs for a return on your investment.

We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ADSs as a source for any future dividend income.

Our Board of Directors has complete discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. ~~In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors.~~ Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our Board of Directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our Board of Directors. Accordingly, the return on your investment in the ADSs will likely depend entirely upon any future price appreciation of the ADSs. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in the ADSs and you may even lose your entire investment in the ADSs.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies ~~Law (2018 Revision)~~Act (As Revised) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands have a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records (other than copies of the memorandum and articles of association, the register of mortgages and charges, and any special resolutions passed by the shareholders) or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxycontest.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by our management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands exempted company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in China. In addition, most of our current directors and officers are nationals and residents of countries other than the United States. Substantially all of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the U.S. federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to direct the voting of your Class A ordinary shares underlying the ADSs.

Holders of ADSs do not have the same rights as our registered shareholders. As a holder of the ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which attach to the underlying Class A ordinary shares represented by your ADSs indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote only by giving voting instructions to the depositary, as holder of the underlying Class A ordinary shares represented by your ADSs. Upon receipt of your voting instructions, the depositary may try to vote the underlying

Class A ordinary shares represented by your ADSs in accordance with your instructions. If we ask for your instructions, then upon receipt of your voting instructions, the depositary will try to vote the underlying Class A ordinary shares in accordance with those instructions. If we do not instruct the depositary to ask for your instructions, the depositary may still vote in accordance with instructions you give, but it is not required to do so. You will not be able to directly exercise any right to vote with respect to the underlying Class A ordinary shares unless you withdraw the shares and become the registered holder of such shares prior to the record date for the general meeting. When a general meeting is convened, you may notreceive sufficient advance notice of the meeting to enable you to withdraw the underlying Class A ordinary shares represented by your ADSs and become the registered holder of such shares prior to the record date for the general meeting to allow you to attend the general meeting and to vote directly with respect to any specific matter or resolution to be considered and voted upon at the general meeting. In addition, under our fourth amended and restated articles of association, for the purposes of determining those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent you from withdrawing the Class A ordinary shares underlying your ADSs and becoming the registered holder of such shares prior to the record date, so that you would not be able to attend the general meeting or to vote directly. Where any matter is to be put to a vote at a general meeting, the depositary will notify you of the upcoming vote and to deliver our voting materials to you. We cannot assure you that you will receive the voting material in time to ensure you can direct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to direct how the underlying Class A ordinary shares represented by your ADSs are voted and you may have no legal remedy if the underlying Class A ordinary shares represented by your ADSs are not voted as you requested.

Our triple-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.

We have adopted a triple-class share structure such that our ordinary shares consist of Class A ordinary shares, Class B ordinary shares and Class C ordinary shares. In respect of matters requiring the votes of shareholders, each Class A ordinary share is entitled to one vote, each Class B ordinary share is entitled to seven votes, and each Class C ordinary share is entitled to ten votes. Each Class B ordinary share or Class C ordinary share is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares or Class C ordinary shares, Class B ordinary shares are not convertible into Class C ordinary shares, and Class C ordinary shares are not convertible into Class B ordinary shares under any circumstances.

Mr. Peng Ou, our founder and chairman of our Board of Directors, Mr. Tongbo Liu, our chief executive officer and director, and certain of our senior management and employees collectively beneficially own all of our issued and outstanding Class C ordinary shares. These Class C ordinary shares constitute approximately ~~62.3%~~60.8% of our total issued and outstanding share capital and ~~85.0%~~84.3% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. In addition, up to ~~414,393~~429,169 ordinary shares reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. PV PLUTO LIMITED, an entity wholly owned and controlled by Primavera Capital Fund, beneficially owns all of our issued and outstanding Class B ordinary shares, which constitutes approximately ~~12.1%~~12.3% of our total issued and outstanding share capital and ~~11.5%~~11.9% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report.

As a result of this triple-class share structure and the concentration of ownership, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees will have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. They may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving our other shareholders of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of the ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

Our tripple-class voting structure may render the ADSs representing our class A ordinary shares ineligible for inclusion in certain stock market indices, and thus adversely affect the trading price and liquidity of the ADSs.

We cannot predict whether our tripple-class share structure with different voting rights will result in a lower or more volatile market price of the ADSs, in adverse publicity, or other adverse consequences. Certain index providers have announced restrictions on including companies with multi-class share structures in certain of their indices. For example, S&P Dow Jones and FTSE Russell have changed their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, to exclude companies with multiple classes of shares and companies whose public shareholders hold no more than 5% of total voting power from being added to such indices. As a result, our tripple-class voting structure may prevent the inclusion of the ADSs representing our class A ordinary shares in such indices, which could adversely affect the trading price and liquidity of the ADSs representing our class A ordinary shares. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structure and our tripple-class structure may cause shareholder advisory firms to publish negative commentary about our corporate governance, in which case the market price and liquidity of the ADSs could be adversely affected.

You may experience dilution of your holdings due to the inability to participate in rights offerings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems it expedient in connection with the performance of its duties. The depositary may close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of the ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements.

We are an “emerging growth company,” as defined in the JOBS Act, and we have taken and intend to continue to take advantage of certain exemptions from requirements applicable to other public companies that are not emerging growth companies, including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 for so long as we remain an emerging growth company. As a result, if we elect to continue to not comply with such auditor attestation requirements, our investors may not have access to certain information they may deem important.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies.

Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis as press releases, distributed pursuant to the rules and regulations of the NYSE. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC are less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domesticissuer.

As an exempted company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the New York Stock Exchange corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the New York Stock Exchange corporate governance listing standards.

As a Cayman Islands exempted company listed on the New York Stock Exchange, we are subject to New York Stock Exchange corporate governance listing standards. However, New York Stock Exchange rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the New York Stock Exchange corporate governance listing standards. We have followed and intend to continue to follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the New York Stock Exchange that listed companies must have: (i) a majority of independent directors; (ii) a nominating/corporate governance committee composed entirely of independent directors; and (iii) a compensation committee composed entirely of independent directors. To the extent we choose to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would enjoy under New York Stock Exchange corporate governance listing standards applicable to U.S. domestic issuers.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. investors in the ADSs or our ordinary shares.

In general, a non-U.S. corporation is a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Cash is a passive asset for these purposes. Based on the composition of our income and assets and the value of our assets, including goodwill, which is based on the price of our ADSs, we do not believe we were a PFIC for the ~~2018~~2020 taxable year. However, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiaries, our consolidated affiliated entities and the shareholders of our consolidated affiliated entities will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we hold a substantial amount of cash ~~after our initial public offering,~~ and because our PFIC status for any taxable year will depend on the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of the ADSs or ordinary shares, which could be volatile), there can be no assurance that we will not be a PFIC for our current or any future taxable year. If we were a PFIC for any taxable year during which a U.S. investor holds ADSs or ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. investor.

Over the past year, we’ve been acutely focused on further enriching both our user experience and brand reputation. We’ve adopted a softer, user-friendly marketing approach and introduced trial programs, allowing us to nurture a growing number of potential users in the adult online education market. In 2018, our new student enrollments grew steadily and our net loss margin improved. At the same time, we maintained user loyalty, retention and satisfaction, all while continuing to target and acquire new students, at a large scale. In the future, we’ll continue to improve both our course quality and brand influence, to better serve an even larger pool of prospective students, in China and around the world.

Sunlands is both a technology and an education company. As a technology company, we focus on using big data technology and artificial intelligence (“AI”) to help our users improve their learning efficiency. As an educational company, we maintain our market leadership through word-of-mouth referrals which we discovered is based on our delivery of high-quality educational content and our brand’s overall premium offerings. Throughout the years, we’ve seen Chinese students shifting from preferring offline classrooms to using online education services, especially amongst adults in the post-secondary and professional education sector. We believe this trend will continue in the future and through several endeavours, we’re well-positioned to seize this tremendous opportunity:

We believe education should nurture and spread new ideas to enrich lives. High-quality education should be available to everyone. We all share a common aspiration to improve ourselves through education. Our mission is to transform education through technology and innovation, making learning experiences enjoyable and rewarding.

We are the leader in China’s online post-secondary and professional education. We have a deep understanding of the educational needs of our prospective students and offer solutions that help them achieve their goals. We offer various ~~degree- and~~degree-and diploma-oriented post-secondary courses through our online platforms. In addition, we offer online professional courses and educational content to help students prepare for professional certification exams and attain professional skills.

Founded in 2003 as a traditional education company, we transitioned to an online education model in 2014. Our online education model enables our students to access our course and educational content offerings anywhere and anytime.

We have been successful in addressing the unmet demand of a large, growing market and served approximately ~~1,309,000~~2,106,000 students across China since we transitioned to an online education model in 2014. The number of our students was ~~382,805, 660,182~~1,039,733 and ~~1,025,959,~~1,130,650, respectively, in ~~2016, 2017~~2019 and ~~2018.~~2020. For the same periods, our new student enrollments were ~~188,733, 387,878~~363,013 and ~~526,014,~~434,240, respectively.

We offer post-secondary and professional education through extensive courses and educational content offerings. As of December 31, ~~2018,~~2020, we offered Self-taught Higher Education Examination, or STE, programs covering 1819 majors, ~~MBA-related~~master's degree-oriented and other degree-or diploma-oriented post-secondary programs, and professional certification and skills programs.

We adopt a counseling-oriented sales and marketing approach that seeks to offer our education solutions to meet their needs based on their education background and goals. We provide professional assistance and counseling to help students make informed decisions that best suit their learning needs. In addition, our enrollment consultants also help them formulate effective study plans throughout their enrollments in our courses.

Our students can access our services either through PC or mobile applications. Our online platform cultivates a personalized, interactive learning environment by featuring a virtual learning community and a vast library of educational content offerings that adapt to the learning habits of our students.

~~Our success has been driven by our ability to cultivate~~We focus on cultivating an engaging community among students, teachers and mentors, ~~strong~~improving educational content development capabilities, and ~~high-quality faculty, which combined allow us to continually improve the student learning experience.~~developing proprietary IT infrastructure and systems.

We ~~also~~ provide our students with strong learning support through our dedicated ~~mentors.~~mentors, powered by our proprietary IT systems and live streaming platform.

We offer a unique approach to education research and development that organizes subject content into Learning Outcome Trees, our proprietary knowledge management system. Our Learning Outcome Trees enable us to customize teaching notes for our teachers, and develop comprehensive course outlines and quiz banks to enhance the learning experience. Based on student feedback and the latest updates on exam policies, we further update our educational content in our Learning Outcome Trees to continually improve teaching quality.

~~We believe our strong branding, competitive compensation structure and robust teaching and research support enable us to attract and incentivize a large team of talented faculty members.~~ We seek to hire experienced and passionate teachers who can make learning fun and interactive. We equip our faculty members not only with a comprehensive set of teaching methods but also advanced technologies and data insights to enable them to develop their professional skills and enhance our overall teaching quality.

We offer our online education services through our online and mobile platforms to adult students pursuing post-secondary and professional education. We deliver a diverse, comprehensive range of online courses in a live streaming format focused on fostering an interactive learning experience and community-oriented student support services. We also provide our students with a variety of proprietary educational content to help reinforce what is taught in classes and assess their learningoutcomes.

We promote our services through a multi-channel strategy, including online and mobile advertising, to effectively convert sales leads into student ~~enrollments in a cost-effective manner.~~enrollments.

Through our technology that connects students with faculty and employees, we gather and analyze data at each stage of our students’ interactions with us in real-time, allowing us to better understand our students’ learning needs and enabling us to continually improve the quality of our service.

We offer a wide range of online courses addressing various educational needs of adults in China.

Currently, our course offerings mainly cover two main components, namely (i) ~~degree- or~~degree-or diploma-oriented post-secondary courses, and (ii) professional certification preparation and professional skills courses. The following table sets forth our net revenues, gross billings ~~net revenues~~ and new student enrollments attributable to each type of course ~~offering:~~offering. For a reconciliation of our gross billings and net revenues, see “—Non-GAAP Financial Measures.”

Our ~~degree- or~~degree-or diploma-oriented post-secondary course offerings primarily consist of preparation courses for ~~the Self-taught Higher Education Examination, or~~ the STE, a state-administered exam in China for learners pursuing associate diplomas or bachelor’s degrees. As of December 31, ~~2018,~~2020, our STE courses covered 1819 majors, including Chinese language and literature, law, pre-school education, marketing, English, human resource management, business administration, business management, modern corporate governance, financial management, advertising, accounting, engineering management, administrative management, computer information management, finance, convention management, ~~and~~ chain operation ~~management.~~management and, visual communication and design. Our ~~degree- or~~degree-or diploma-oriented post-secondary course offerings also include preparation courses for the entrance examinations of Master of Business Administration in China, or MBA programs offered by select universities in ~~China,~~ United States, Australia, Spain, Republic of Belarus, and ~~Australia.~~Malaysia.

STE courses have historically accounted for the largest proportion of our net revenues, gross billings and new student enrollments. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, STE courses represented approximately ~~66.3%~~85.8%, ~~80.6%~~80.5% and ~~85.8%~~66.8%, respectively, of our net revenues, and approximately ~~79.0%~~88.3%, ~~89.2%~~75.1% and ~~88.3%~~53.1%, respectively, of our gross billings. In addition, STE courses represented approximately ~~61.7%~~80.1%, ~~80.1%~~75.4% and ~~80.1%~~46.2%, respectively, of our new student enrollments for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018.~~2020. See also “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We face risks associated with our reliance on our STE course offerings, including risks resulting from changes in government policies or requirements relating to STE exams.”

In 2020, we expanded our course portfolio and built partnerships with more overseas universities to offer joint programs for Master’s degree-oriented courses. During the year, we sought to provide diversified online courses to meet Chinese students’ growing demands for quality overseas higher education from Europe and the United States, especially as the COVID-19 pandemic restricted travel. For example, we established partnership with Belarusian State University during the third quarter to offer online courses focused on MBA degrees. We plan to maintain efforts to explore such alliances as we continue to diversify our curriculum mix.

Our professional certification preparation course offerings cover various industries and professions, including accounting, human resources, teaching and finance. Our professional skills courses are designed to give our students the skills, knowledge and abilities that are commonly required or otherwise helpful for a broad range of professions. Also, our further development of more professional skills-related certification programs and general interest courses yielded very encouraging results in 2020. As of December 31, ~~2018,~~2020, our ~~professional~~ certification programs included a variety of preparation ~~and professional skills~~ courses ~~primarily included certificates~~ for professionals ranging from teachers, accountants and tour guides, as well as certifications for human resources professionals and ~~certified~~ public accountants. In addition, we also developed more general interest courses as we saw a surging trend in adults undertaking interest courses online, such as wealth management courses, voice acting courses, Mandarin courses and animation design courses. Our course portfolio’s solid foundation has enabled us to successfully grasp market opportunities and effectively scale up our offerings as we remain fully committed to giving our users as many options as possible.

In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our professional certification preparation and professional skills courses represented approximately ~~28.8%~~8.1%, ~~15.0%~~7.1% and ~~8.1%~~12.2%, respectively, of our net revenues, and approximately ~~16.1%~~6.2%, ~~7.6%~~6.9% and ~~6.2%~~19.9%, respectively, of our gross billings. In addition, our professional certification courses represented approximately ~~36.5%~~16.5%, ~~18.3%~~15.6% and ~~16.5%~~43.5%, respectively, of our new student enrollments in ~~2016, 2017~~2018, 2019 and ~~2018.~~2020.

In addition to the course offerings discussed above, we also offer exam preparation “crash courses” for exam-taking students. Instead of covering a wide range of topics in a particular subject matter, these courses are meant to cover the most frequently tested areas in the exams and provide training on test-taking strategies and skills to help our students improve their performance in actual exams.

Our teachers deliver our courses in a live streaming format through our websites and our mobile application. We believe that we are one of the first to offer live streaming courses in China’s education industry.

Our live streaming course delivery format allows us to cost-effectively expand student enrollments and maintain high teaching quality. Live streaming also improves efficiency of instruction and enriches the learning experience in a number of ways:

We believe our live streaming format and our highly interactive learning experience makes our services highly attractive to students. Our new student enrollments have increased ~~significantly~~ since we transitioned to the live streaming format in 2014. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our new student enrollments were ~~188,733, 387,878~~526,014, 363,013 and ~~526,014,~~434,240, respectively.

We strive to build a vibrant and highly interactive virtual community for our students and faculty to augment their learning and teaching experience. For example, we have a bulletin board forum, available through our website and mobile application that enables our students in real time to share their ideas and learning experience with, as well as pose questions and answers to fellow students and our faculty. This also provides a stimulating learning platform for our students to socialize and interact with an extended network of fellow students and faculty members and to forge beneficial relationships. In addition, our students can authorize his or her fellow students to view their learning progress and milestones, thus fostering an engaging and friendly competitive environment.

We believe a highly interactive virtual student community drives our existing students’ level of engagement and significantly enhances our attractiveness to prospective students.

Our classes are set up to cultivate an interactive learning environment. We are committed to developing a sense of community among our students and faculty, which we believe is critical to improving results.

Furthermore, our community-oriented learning environment, coupled with our student-centric faculty structure, enable us to provide our students attention and support beyond class hours at a time and in a manner that is convenient to them, which further drives student engagement, customer loyalty and course consumption.

Our class are set up by schools, divisions and classes. Students are assigned to different schools and divisions based on the major and number of students enrolled for a given academic period. Students in the same division are further assigned to different “classes” for administrative purposes.

We ~~believe our strong in-house course and educational content development capabilities are critical to maintaining our education service quality and differentiating us from our competitors.~~

We maintain an experienced team of course and educational content development professionals. Our course and educational content development team is dedicated to designing course offerings, as well as developing and improving a wide range of proprietary educational content, such as course outlines, quiz banks and teaching notes, for substantially all of our online course offerings.

We regularly upgrade our educational content to make it more practical, and easier to comprehend and apply in real exams. For instance, we regularly release major updates to our proprietary quiz banks and mock questions for students pursuing the STE exams to reflect updates in the test topics in the government-administered STE exams. Benefiting from our IT infrastructure, our course and educational content development team is able to view and analyze student performance in quiz banks and mock questions, which enables them to identify weaknesses in the educational content and make timely adjustments and upgrades accordingly. Our course and educational content development team also seeks feedbacks from teachers and students regarding the effectiveness of our educational content, through online questionnaires or in-person meetings.

In addition to our proprietary educational content, our course and educational content development professionals also design and recommend to our ~~teachers~~teachers’ best practices in teaching methods. While our teachers retain substantial control of and flexibility in the way their classes are taught, our course and educational content development professionals continually work closely with them to ensure our courses and educational content are delivered in an engaging, effective manner. We use Learning Outcome Trees to help us structure and deliver our educational content offerings, including course outlines, teaching notes and quiz banks, more effectively.

We support the learning experience with a wide range of educational content designed to help them capture key takeaways from, and reinforce what is taught in, our live streaming lessons, and to assess learning outcomes both during and after class hours. We also provide our teachers with educational content to help them prepare and teach classes effectively. All of our educational content was developed by our in-house research and development team and distributed electronically to our students and faculty through our onlineplatforms.

We have a large ~~fast-growing~~ student base, primarily as a result of our well-established brand and effective sales and marketing efforts. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, we had ~~382,805, 660,182~~1,025,959, 1,039,733 and ~~1,025,959~~1,130,650 students, respectively, and our new student enrollments were ~~188,733, 387,878~~526,014, 363,013 and ~~526,014,~~434,240, respectively.

~~We believe our success is largely attributable to our deep understanding of our students.~~ Our students are primarily working adults who generally have limited time to devote to lengthy and regular classroom studies at designated physical locations. Such students also need an engaging learning atmosphere that encourages participation and interaction, and require more assistance and supervision from their teachers and mentors.

Our target students generally have aspirations to obtain more knowledge, pursue higher education and improve their social and economic status. At the same time, many of them cannot identify their specific education needs or solutions for such needs, especially given that education products and services can be complex and the relatively high costs may deter them from fulfilling their educational needs. To help them meet their aspirations and understand the potential educational solutions, we focus our marketing and sales practices on counseling-oriented interactions and strive to deliver our courses and educational content in a highly engaging and student-friendlymanner.

We maintain a large full-time faculty dedicated to helping our students succeed. As of December 31, ~~2018,~~2020, our faculty primarily consisted of ~~161~~171 teachers and 640 mentors based in Beijing, Guangzhou and Wuhan, China.

Our teachers and mentors assume different roles and responsibilities. Generally, our teachers are responsible for delivering courses and educational content to our students, while our mentors focus on providing academic and administrative support tothroughout the ~~students beyond class hours.~~students’ learning process. We believe their different functions require different skills and personal attributes, and therefore we apply differentiated recruitment, training, and evaluation and compensation strategies to our teachers and mentors. For risks related to our faculty, see “Item 3. Key Information—3.D. Risk Factors—Risk Factors— Risks Related to Our Business—We may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members.”

We believe maintaining a high-quality team of teachers is the bedrock of our brand and reputation, particularly given our online course delivery model where each teacher is expected to cover a larger number of students than in offline, classroom-based courses. We monitor the total number of hours our teachers teach regularly to provide both an optimal number of teachers for our large ~~fast-growing~~ student enrollments and adequate teaching assignments for each of our teachers. All of our teachers are our full-time employees. The training we provide to teachers is designed to allow teachers to develop their own teaching style and methodology while maintaining high teaching quality.

We hire our teachers based on numerous criteria, including educational backgrounds, teaching experience, and performance in mock lessons. We typically look for candidates with a bachelor’s degree from a top university or college in China or a master’s or higher degree. Additionally, given the interactive nature of our live streaming lessons, we look for teachers with strong communication skills, ~~in an online setting~~great passion for teaching and ~~the~~excellent ability ~~to make the courses more interactive to drive student engagement.~~of working under pressure.

We offer standard training programs to newly-hired teachers. We also impose a probation period and require each newly hired teacher to pass ana number of internal qualification ~~test at the end of~~tests throughout the probation to be formally employed as full-time teachers. We also provide on-the-job training on instructional and communication skills to our teachers on a regular basis. ~~We also provide technical support for~~Our proprietary IT system is key to our ~~teachers that~~teacher training efforts as it not only allows them to monitor student engagement and academic performance on a real time ~~basis.~~basis but also to adjust teaching methodology and strategy accordingly to keep students engaged.

We have developed a fully-digital and systematic assessment approach that provides teachers with transparent and helpful feedback that serves as the foundation for their professional development and helps them to build fulfilling careers with us. We adopt a comprehensive set of key performance indicators, or ~~KPIs,~~metrics, to evaluate teacher performance. These ~~KPIs~~metrics include student attendance rate and student satisfaction, among others. We also collect student reviews after each class and closely monitor the educational content delivered by our teachers to facilitate our teacher evaluation efforts and to improve our teaching quality. In addition, we use mock lessons to assess a teacher’s teaching skills and ability to engage students in a live streaming course setting, especially in instances where multiple teachers are competing to teach the same course.

We pay our teachers base salaries and service fees generally on a per-lesson basis. The service fees per lesson of a teacher are based primarily on his or her rating and other factors, such as student ~~reviews.~~reviews and exam results. To incentivize our teachers, we also provide them with discretionary, merit-based bonuses based on their performance, measured by selected ~~KPIs.~~metrics. We enter into with each teacher a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

Our mentors’ principal role is to provide academic guidance and support to our students on a daily basis to help navigate their way throughout the entire duration of studies. Our mentors’ roles and responsibilities typically include:

We tend to look for mentors who demonstrate excellent interpersonal and communication skills and a commitment in participating in the education profession and impacting a diverse audience. We typically require our mentors to possess a bachelor’s degree.

We provide our mentors with an orientation program and periodic on-the-job training to improve their ability to engage and build relationships with students. We also provide our mentors with training opportunities that address specific challenges. We have also introduced systems and tools that enable our teachers to monitor student activities and outcomes and take appropriate actions when the students demonstrate a low level ofengagement.

We use various ~~KPIs~~metrics in terms of student engagement to measure the performance of our mentors. These ~~KPIs~~metrics include student’s class attendance, refund request rate, as well as the percentage of outperforming students. With each of our mentors we enter into a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

Our marketing philosophy is to promote our services to prospective students in a cost-effective manner based on our deep understanding of their unique profile and needs. We have acquired many of our existing students through effective marketing campaigns focused on showing how our services can address their specific educational needs. At the same time, we market our services to a larger group of prospective students who are not aware of solutions available to satisfy their needs through tailored marketing efforts designed to awaken their potential demands and navigate them through their decision-makingprocess. In 2018, we further refined our marketing tactics by offering a broader variety of trial of selected course offerings and we also began to outsource certain of our sales and marketing functions to third-party service providers with a goal to improve our operating efficiency and streamline our sales and marketing efforts.

We believe that our distinguished online education services has led to strong word-of-mouth promotion, which drives our brand awareness and rapid organic enrollment growth and enables us to market in a cost-effective manner. For the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our marketing effectiveness ratio, measured by dividing marketing spending by gross billings, was ~~24.8%~~29.1%, ~~20.2%~~40.2% and ~~29.1%~~46.9%, respectively.

We have built a large, well-trained professional sales and marketing team. As of December 31, ~~2018,~~2020, we ~~used services provided by~~had a total of approximately ~~7,800~~5,700 sales and marketing personnel, consisting of 1,746 sales and marketing personnel employed by us and approximately 6,100 sales and marketing personnel dispatched by third-party service providers pursuant to the business process outsourcing service contracts between us and such third-party service providers, the majority of whom were based in Beijing and Wuhan.personnel.

We engage in a variety of advertising and marketing activities to build our brand and use a combination of online and offline channels.

We generate our leads primarily from online channels, which consist of search engine marketing and mobile marketing. Empowered by our data analytics capabilities, we use automated bidding strategies to place ads intelligently, as well as to track performance of our ads in real time, which enables us to generate more qualified clicks leading to our websites. We put ads on strategically chosen mobile applications that generate premium traffic quality to maximize our return of investment from mobile marketing channels.

Our search engine marketing channels effectively target students who possess preliminary interest in our services. We purchase key words from major search service providers in China, such as Baidu, and enhance returns from search engine marketing channels using search engine optimization techniques. We monitor end-to-end performance metrics of our search engine marketing channels on a continuous basis.

We also generate leads online through mobile marketing channels, which mainly include display advertising on leading mobile news apps, as well as social media platforms and online shopping platforms. The display advertising formats we use

generally include launch screen display, banners, text hyperlinks, videos and rich media. We also operate a branded official accounts on Weixin/WeChat, ~~official account~~Sina Weibo, Tik Tok and other social media platforms to raise our brand awareness and increase sales leads generated on ~~the Weixin/WeChat platform.~~these platforms. We believe that our mobile marketing efforts are particularly effective in awakening potential demands of prospective students who have not yet developed a specific learning plan. ~~As we continue to focus on acquiring students through various mobile marketing channels, our mobile student acquisition rate remained stable at approximately 71.0% in both 2017 and 2018.~~

The terms of the agreements we enter into with our search engine and mobile marketing partners are typically one year. We pay our search engine and mobile marketing partners generally on a cost-per-click basis.

In addition to online advertising focused on mobile applications with high traffic volume, we engage in offline branding activities to a much lesser extent to supplement our overall sales and marketing strategies. Our offline branding activities primarily include public displays at major subway stations in Beijing, ~~Shanghai, Guangzhou and Shenzhen,~~ as well as establishment of ~~120~~78 enrollment centers strategically located in our regional markets as of December 31, ~~2018.~~2020. We believe that these cities represent the largest student base in China, and the primary goal of these advertisements is to enhance our presence in the local markets.

To convert leads generated into student enrollments, we provide customized, comprehensive counseling to prospective students throughout the lead nurturing and enrollment cycle. This counseling-oriented sales approach is supported by a capable sales team consisting of live chat personnel, call center staff and recruitment consultants based in our regional enrollment centers. We provide extensive training to our sales team to ensure they are capable of explaining our course offerings, addressing questions and concerns, and recommending courses that best suit prospective students’ learning objectives. We also use our data analytics tools and models to identify a prospective student’s educational needs, which helps our sales team provide tailor-made counseling services.

We use multi-layer lead-nurturing strategies to acquire new student enrollments in a cost-effective manner. Each of the leads generated are initially directed to our live chat support team who is responsible for answering prospective students’ enquires, encouraging them to register with our platforms, and collecting necessary information. Once a prospective student indicates an interest in purchasing our courses, we match such student with the most suitable sales professional based on our data analytics and tools. Such sales professional will follow up with the prospective student. In addition, we launch advertisements on varioius platforms, where we are able to obtain the contact information of our prospective students if they indicate interest in our courses. We then invite prospective students to join our online learning group and provide them with access to our trial courses. A prospective student that has signed up for our courses will be directed to our local enrollment centers to complete course purchase and registration with the assistance of our enrollment consultants. Our enrollment consultants are also responsible for providing counseling services to enrolling students and guiding them through the payment process. Our students can also choose to complete the purchase and enrollment process entirely online.

We launched our trial program, which are offered to prospective students for free or at very low price, in April 2018. We currently offer introductory seminars, which enable prospective students to see first-hand how our course offerings work, as well as select short-courses to provide our students with free introductory learning opportunities. We believe our upgraded trials with introductory seminars and short-courses can, over time, increase average gross billings, conversion rates and sales efficiency.

We devote significant resources to maintaining a reliable, scalable and secure IT infrastructure. We have built our integrated IT infrastructure primarily based on tools, technologies and platforms that we have developed in-house and, to a lesser extent, third-party software and applications that we have licensed or purchased.

We maintain a dedicated IT development and support team. As of December 31, ~~2018,~~2020, we had ~~771~~324 technology development personnel.

Our IT infrastructure is critical to supporting our pursuit of excellent student experience and optimal operating efficiency. We have developed Genesis, our proprietary integrated IT infrastructure, to support and connect our students and employees during every major aspect of our business operations, encompassing marketing, sales, course delivery and development, and operation management.

Powering various services and functions, including information and data transmission and sharing, centralized data tracking and data analytics, Genesis is composed of both student interface and employee interface. For one thing, the student

interface supports applications and platforms that enable our students to enroll in courses, attend classes, access educational content, interact within our virtual community, and engage in other learning activities throughout their service periods; for another thing, Genesis also incorporates different subsets of functions used by our employees, ranging from our teachers and mentors to our marketing and sales personnel. The employee interface is specifically customized to provide our employees with information and data most relevant to their responsibilities. In addition, Genesis supports a centralized database allowing its users, including our students and employees, to contribute, share and store content and data across our various applications and platforms.

We launched our AI-powered personalized study programs in 2018. This AI-powered software, developed in-house, uses machine learning and natural language processing technology to analyze student behavior and their level of understanding of specific courses. Based on this analysis, we are able to predict test results, with a high accuracy rate, and develop tailor-made learning solutions that are designed to improve study outcomes.

We are one of the first movers in China’s education sector to deliver interactive education services via mobile platforms, which has enabled students to learn and connect with fellow students and faculty in a more efficient and flexible manner. Our Sunlandsmobile app, available on both iOS and Android, is built with a clear and functional interface that enables access to our course and educational content offerings and our virtual learning community. We have also built mobile WAP pages which allow our students and faculty to enjoy a similar level of functionality as our mobile app without installation. In January 2019, we launched Sunlands Speed Edition, a mobile app offering free courses in a variety of subjects and areas to engage a broad range of learners.

Ourtuitionfees,includingacademicfeesandregistrationfees,arechargedgenerallyonaper-programbasis. From time to time, we offer tuition discounts under various marketing campaigns and promotions. For example, discountsmayalsobemadeavailabletostudentswhopurchasemultiplecoursesatatime.Weacceptfeepayments throughmajorthird-partyonlinepaymentsolutionsinChina,includingAlipay,UnionPayandWeChatPay,aswell asbanktransfersandcreditcards.

Students typically self-finance their education or obtain financing from third-party financing programs that cooperate with us. We currently offer the following two payment options to our students:

We generally offer students a full, unconditional refund within 24 hours upon enrollment. If a student requests a refund after taking at least one live streaming course lasting 30 minutes due to any material academic issue associated with our courses within certain refund period, we offer a ~~partial refund.~~refund excluding the registration fees and the fees of delivered courses upon our confirmation. In addition, we ~~may at our discretion grant a partial refund to a student who withdraws at any other time during his or her enrollment, subject to special approval by us. Historically, we allowed our~~offer students ~~to obtain~~ a refund ~~under certain conditions.~~for the undelivered courses excluding the registration fees. Prior to June 2019, such refund was provided only within seven days upon enrollment while starting from June 2019, we offer such refund during the entire service period. When calculating gross billings for a specific period, we deduct the total amount of refunds from the total amount of cash received for the sale of course packages for such period.

Starting in 2018, for certain online courses, we also offer students a bundled service including an integrated online education service package and insurance coverage for tuition refund provided by insurance companies collaborated with us. If the refundable conditions are met, students could claim the insurance equal to the full or partial amount of the tuition fees.48

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We own copyrights to the educational content we developed in-house. We enter into standard employment agreements with our teachers, course development staff and other employees which provide that the intellectual property created by them in connection with their employment with us is our intellectual property. As of the date of this annual report, we have registered 3544 trademarks with the Trademark Office of the PRC State Administration of Industry and Commerce, registered 75100 software copyrights with the PRC State Copyright Bureau, and registered ~~183~~273 domainnames.

Despite our efforts to protect ourselves from infringement or misappropriation of our intellectual property rights, unauthorized parties may attempt to copy or otherwise obtain and use our intellectual property. In the event of a successful claim of infringement and our failure or inability to develop non-infringing intellectual property or license the infringed or similar intellectual property on a timely basis, our business could be harmed. See “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We may from time to time be subject to infringement claims relating to intellectual properties of third parties.” and “—If we fail to protect our intellectual property rights, our brand and business may suffer.”

We competewithourcompetitorsforstudentenrollmentsandengagement,high-qualityfacultymembers,salesand ~~engagement, high-quality faculty members, sales~~ ~~and~~ marketingeffectiveness,amongotherthings.

We believe that the principal competitive factors in China’s post-secondary and professional education market include the following:

We believe we compete favorably on the basis of these factors. Our ability to remain competitive will depend, to a great extent, upon our ability to consistently deliver high-quality course offerings and acquire, support and retain students. Some of our present and future competitors may have longer operating histories, larger teams of teaching faculty and supporting staff and greater financial, technical, marketing and other resources. For a discussion of risks relating to competition, see “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We face intense competition in our industry, which could divert student to our competitors, lead to pricing pressure and loss of market share, and significantly reduce our gross billings and net revenues.”

We do not maintain any liability insurance or property insurance policies covering students, equipment and facilities for injuries, death or losses due to fire, earthquake, flood or any other disaster. Consistent with customary industry practice in China, we do not maintain business interruption insurance, nor do we maintain key-man life insurance.

According to the latest Special Administrative Measures for the Entry of Investment ~~activities in the PRC by foreign investors are principally governed by the Guidance Catalog of Industries for Foreign Investment,~~(Negative List), or the ~~Catalog, which was~~Negative List, promulgated ~~and is amended from time to time~~ by the Ministry of Commerce, or MOFCOM and the National Development and Reform Commission, or NDRC. The current Catalogue consists of the list of encouraged industries and the list of special management measures for the market entry of foreign investment, or the Negative List. On June 28, 2018, the NDRC, ~~and the MOFCOM updated the Negative List, which became~~ effective on July ~~28, 2018 and sets forth management measures for the market entry of foreign investors, such as equity requirements and senior manager requirements.~~

According to the Negative List, foreign investors shall comply with such restrictive requirements when engaging in the restricted activities listed in the Negative List. In addition, according to the Negative List,23, 2020, foreign investors shall not engage in the prohibited activities listed in the Negative List. Pursuant to the latest Negative List, the provision of value-added telecommunications services falls in the category of restricted activities and, with a few exceptions, the percentage of foreign ownership cannot exceed50% (except for e-commerce, domestic multi-party communication, store-and-forward and call center).

On March 15, 2019, the Standing Committee of the National People’s Congress published the Foreign Investment Law, or the FIL, which became effective on January 1, 2020. The FIL is expected to replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The existing foreign-invested enterprises established prior to the effective of the FIL may keep their corporate forms within five years. Pursuant to the FIL, “foreign investors” means natural person, enterprise, or other organization of a foreign country, “foreign-invested enterprises” (FIEs) means any enterprise established under PRC law that is wholly or partially invested by foreign investors and “foreign investment” means any foreign investor’s direct or indirect investment in mainland China, including: (i) establishing FIEs in mainland China either individually or jointly with other investors; (ii) obtaining stock shares, stock equity, property shares, other similar interests in Chinese domestic enterprises; (iii) investing in new projects in mainland China either individually or jointly with other investors; and (iv) making investment through other means provided by laws, administrative regulations, or State Council provisions.

The FIL stipulates that China implements the management system of pre-establishment national treatment plus a negative list to foreign investment and the government generally will not expropriate foreign investment, except under special circumstances, in which case it will provide fair and reasonable compensation to foreign investors. Foreign investors are barred from investing in prohibited industries on the negative list and must comply with the specified requirements when investing in restricted industries on that list. When a license is required to enter a certain industry, the foreign investor must apply for one, and the government must treat the application the same as one by a domestic enterprise, except where laws or regulations provide otherwise. In addition, foreign investors or FIEs are required to file information reports and foreign investment shall be subject to the national security review.

On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the FIL and further provides, among others, (i) an FIE’s investment within the territory of PRC is also subject to the FIL and the Implementation Rules of Foreign Investment Law; (ii) an FIE may, within five years following January 1, 2020, choose to amend its legal form or the corporate governance and complete amendment registration, or to keep its original legal form or the corporate governance; (iii) the provisions regarding the transfer of equity interests, distribution of profits and remaining assets as stipulated in the contracts among the joint venture parties of an existing FIE may survive the FIL after such FIE amends its legal form or the corporate governance in accordance with relevant applicable laws.

On December 30, 2019, MOFCOM and the SAMR, jointly issued the Measures for Reporting of Foreign Investment Information, which came into effect on January 1, 2020. Since January 1, 2020, for foreign investors carrying out investment activities directly or indirectly in the PRC, foreign investors or foreign-invested enterprises shall submit investment information through certain system operated by SAMR. Foreign investors or foreign-invested enterprises shall disclose their investment information by submitting reports for their establishments, modifications and cancellations and their annual reports. If a foreign-invested enterprise investing in the PRC has finished submitting its reports for its establishment, modifications and cancellation and its annual reports, the relevant information will be shared by the competent market regulation department to the competent commercial department, and does not require such foreign-invested enterprise to submit the reports separately.

The PRC Regulations on Telecommunications, or the Telecommunications Regulations, which was latest amended and came into effect on February 6, 2016, regulate telecommunications activities in China. The Telecommunications Regulations divide the telecommunications services into two categories, namely “infrastructure telecommunications services” and “value-added telecommunications services.” Pursuant to the Telecommunications Regulations, operators of value-added telecommunications services must first obtain a Value-added Telecommunications Business Operating License, or VAT License, from the Ministry of Industry and Information Technology, or MIIT, or its provincial level counterparts. On July 3, 2017, the MIIT promulgated the Administrative Measures on Telecommunications Business Operating Licenses, which set forth more specific provisions regarding the types of licenses required to operate value-added telecommunications services, the qualifications and procedures for obtaining such licenses and the administration and supervision of such licenses.

According to the Catalog of Classification of Telecommunication Businesses, or the 2016 MIIT Catalog, which published by MIIT on December 28, 2015 and took effect on March 1, 2016 and were amended on June 6, 2019, internet information services, which include information release and delivery services, information search and query services, information community platform services, information real-times interactive services, and information protection and processing services, are classified as a category of value-added telecommunication services. The Administrative Measures on Internet Information Services, or ICP Measures, also promulgated by the PRC State Council on September 25, 2000 and most recently amended on January 8, 2011, set forth more specific rules on the provision of ICP services. According to ICP Measures, any company that engages in the provision of commercial ICP services shall obtain a sub-category VAT License for Internet Information Services, or ICP License, from the relevant government authorities before providing any commercial internet content services within the PRC, and when the ICP services involve areas of news, publication, education, medical treatment, health, pharmaceuticals and medical equipment, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP License from the MIIT or its provincial level counterpart. Pursuant to the ~~above- mentioned~~above-mentioned regulations, “commercial ICP services” generally refers to provision of specific information content, online advertising, web page construction and other online application services through internet for profit making purpose. Operating our online platform to provide information and services to our students is classified as commercial ICP services.

The Regulations on Administration of Foreign-Invested Telecommunications Enterprises, or the FITE Regulations, which took effect on January 1, 2002 and latest amended on February 6, 2016, are the key regulations that regulate foreign direct investment in telecommunications companies in China. The FITE Regulations stipulate that, except as otherwise provided by MIIT, the foreign investor of a telecommunications enterprise is prohibited from holding more than 50% of the equity interest in a foreign-invested enterprise that provides value-added telecommunications services. In addition, for a foreign investor to acquire any equity interest in a business providing value-added telecommunications services in China, it must demonstrate a positive track record and experience in providing such services.

On July 13, 2006, the MIIT issued the Circular on Strengthening the Administration of Foreign Investment in Value-added Telecommunications Services, or the MIIT Circular 2006, which requires that (i) foreign investors can only operate a telecommunications business in China through establishing a telecommunications enterprise with a valid telecommunications business operation license; (ii) domestic license holders are prohibited from leasing, transferring or selling telecommunications business operation licenses to foreign investors in any form, or providing any resource, sites or facilities to foreign investors to facilitate the unlicensed operation of telecommunications business in China; (iii) value-added telecommunications services providers or their shareholders must directly own the domain names and registered trademarks they use in their daily operations; (iv) each value-added telecommunications services provider must have the necessary facilities for its approved business operations and maintain such facilities in the geographic regions covered by its license;

and all value-added telecommunications services providers should improve network and information security, enact relevant information safety administration regulations and set up emergency plans to ensure network and information safety. The provincial communications administration bureaus, as local authorities in charge of regulating telecommunications services, (i) are required to ensure that existing qualified value-added telecommunications service providers will conduct a self-assessment of their compliance with the MIIT Circular 2006 and submit status reports to the MIIT before November 1, 2006; and (ii) may revoke the value-added telecommunications business operation licenses of those that fail to comply with the above requirements or fail to rectify such noncompliance within specified time limits. Due to the lack of any additional interpretation from the regulatory authorities, it remains unclear what impact MIIT Circular 2006 will have on us or the other PRC internet companies with similar corporate and contractual structures. After the MOFCOM and NDRC amended the Catalog in March 2015, MIIT also issued the Circular on Removing the Restrictions on Shareholding Ratio Held by Foreign Investors in Online Data Processing and Transaction Processing (Operating E-commerce) Business on June 19, 2015, which amended the relevant provision in FITE Regulations by allowing foreign investors to own more than 50% of the equity interest in an operator of e-commerce business. However, foreign investors continue to be prohibited from holding more than 50% of the equity interest in a provider of other categories of value-added telecommunications services except for ~~e-commerce.~~e-commerce, domestic multi-party communication, store-and-forward, and call center.

To comply with the above-mentioned foreign ownership restrictions, we operate our online platform in China through Beijing Sunlands and its wholly owned subsidiary, Shangren Chongye, all of the shareholders of Beijing Sunlands are PRC domestically funded entities, and ~~are~~Beijing Sunlands is controlled by Wuhan Zhibo, our PRC subsidiary, through a series of contractual arrangements. Beijing Sunlands and Shangren Chongye are the holders of the domain names, trademarks and facilities necessary for daily operations of our online platforms in compliance with the MIIT Circular 2006. Based on our PRC legal counsel’s understanding of the current PRC law, rules and regulations, ~~our corporate structure complies with all existing~~the contractual arrangements among Wuhan Zhibo, Beijing Sunlands and its shareholders and subsidiaries are valid, binding and enforceable under current PRC ~~laws and regulations.~~law. However, we were further advised by our PRC legal counsel that there are substantial uncertainties with respect to the interpretation and application of existing or future PRC laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with the opinions of our PRC legal counsel.

On March 18, 1995, the PRC National People’s Congress promulgated the Education Law of the PRC, or the Education Law, which was further amended on August 27, 2009 and on December 29, 2018, stipulates that the government formulates plans for the development of education, establishes and operates schools and other types of educational institutions, and in principle, enterprises, institutions, social organizations and individuals are encouraged to operate schools and other types of educational organizations. Comparing to the version of Education Laws that was amended and came into effect on 2009, which provided that no organization or individual may establish or operate a school or any other educational institution for commercial purposes, the current Education Law narrowed the provision prohibiting the establishment or operation of schools or other educational institutions for commercial purposes to only restricting a school or other educational institution founded with governmental funds or donated assets in the amended EducationLaw.

The Law for Promoting Private Education of the PRC became effective on September 1, 2003 and was last amended on ~~June~~December 29, ~~2013,~~2018, and the Implementation Rules for the Law for Promoting Private Education, or PE Implementation Rules of the PRC became effective on April 1, 2004. Under these regulations, “private schools” are defined as schools established by social organizations or individuals using non-government funds. Private schools providing academic qualifications education, kindergarten education, education for self-study examination and other education shall be subject to approval by the education authorities at or above the county level, while private schools engaging in occupational qualification training and occupational skill training shall be subject to approvals from the authorities in charge of labor and social welfare at or above the county level. A duly approved private school will be granted a private school operating permit, and shall be registered with the Ministry of Civil Affairs of the PRC, or the MCA, or its local counterparts as a privately run non-enterprise institution.

Under the above regulations, the operations of a private school are highly regulated. For example, the types and amounts of fees charged by a private school providing academic qualifications education shall be approved by relevant government authorities and publicly disclosed, and a private school that provides non-academic qualifications education shall file its pricing information with the relevant government authorities and publicly disclose such information.

The Decision of the ~~NPC~~ Standing Committee of the National People’s Congress on Amending the Law for Promoting Private Education of the PRC, or the Amendment, has been promulgated by Order No. 55 of the President of the PRC on November 7, 2016 and came into force on September 1,2017.

Under the Amendment, sponsors of private schools may choose to establish non-profit or for-profit private schools at their own discretion. Nonetheless, school sponsors are not allowed to establish for-profit private schools that are engaged in compulsory education. In other words, the schools engaged in compulsory education should retain their non-profit status after the Amendment comes into force. The Amendment further establishes a new classification system for private schools to be classified by whether they are established and operated for profit-making purposes.

~~According to the Amendment, the key features of the aforesaid new classification system for private schools include the following:~~

On December 29, 2016, the State Council issued the Several Opinions of the State Council on Encouraging the Operation of Education by Social Forces and Promoting the Healthy Development of Private Education, or the State Council

Opinions, which requires to ease the access to the operation of private schools and encourages social forces to enter the education industry. The State Council Opinions also provides that each level of the people’s governments shall increase their support to the private schools in terms of financial investment, financial support, autonomy policies, preferential tax treatments, land policies, fee policies, autonomy operation, protecting the rights of teachers and students etc. Further, the State Council Opinions require each level of the people’s governments to improve its local policies on government support to for-profit and non-profit private schools by ways of preferential tax treatments etc. In addition, under the State Council Opinions, private schools shall strengthen its construction of the Chinese Communist Party, or the CCP, and further the theoretical system of Socialism with Chinese Characteristics by introducing such system into textbooks and teaching programs. The construction of the CCP’s organizations by the private schools as well as the CCP’s leadership to private schools shall constitute an important part of such ~~schools~~schools’ annual inspection.

On December 30, 2016, the MOE, ~~MCA, SAIC,~~Ministry of Civil Affairs, State Administration for Industry and Commerce (the predecessor of the State Administration for Market Regulation), the Ministry of Human Resources and Social Welfare and the State Commission Office of Public Sectors Reform jointly issued the Implementation Rules on the Classification Registration of Private Schools to reflect the new classification system for private schools as set out in the Amendment. Generally, if a private school established before promulgation of the Amendment chooses to register as a non-profit school, it shall amend its articles of association, continue its operation and complete the new registration process. If such private school chooses to register as a for-profit school, it shall conduct financial liquidation process, have the property rights of its assets such as lands, school buildings and net balance being authenticated by relevant government authorities, pay up relevant taxes, apply for a new private school operating permit, re-register as for-profit school and continue its operation. Specific provisions regarding the above registrations are yet to be introduced by people’s governments at the provinciallevel.

On December 30, 2016, the MOE, ~~SAIC~~State Administration for Industry and Commerce and the Ministry of Human Resources and Social Welfare jointly issued the Implementation Rules on the Supervision and Administration of For-profit Private Schools, pursuant to which the establishment, division, merger and other material changes of a for-profit private school shall first be approved by the education authorities or the authorities in charge of labor and social welfare, and then be registered with the competent branch of ~~SAIC.~~State Administration for Industry and Commerce. In addition, it also provides that for-profit private training institutes shall be analogically governed by these Implementation Rules on the Supervision and Administration of For-profit Private Schools.

On August ~~31, 2017, SAIC and MOE jointly promulgated the Notice of the State Administration for Industry and Commerce and~~10, 2018, the Ministry of ~~Education on~~Justice, or MOJ, published the Work Concerning the Administration of the Name Registration for For-profit Private Schools, which came into effect on September 1, 2017. Such notice requires that private schools shall not use the names or the abbreviations or the particular appellations that are already registered by other schools, unless such private schools have obtained proper authorization from or have investment relationship with these schools. In additions, such notice provides that the industry expression in the name of the private culture education institutions shall typically include “school” or “center,” such as “curriculum training school/center,” “extra-class education school/center,” “self-learning school/center,” “tutorship school/center,” “extra tutoring for examinations school/center” and “extra tutoring school/center” and such industry expression is allowed to embody the disciplines and characteristics of such education institution, such as “English training school.”

Besides the Amendment, the details of the operation requirement of non-profit schools and for-profit schools will further be provided in implementation regulations (the “Implementation Regulations”) which include:

public comment. As of the date of this annual report, ~~certain local governments,~~this MOJ Draft is still pending for ~~example, Beijing, Shanghai, Jiangsu province, Hebei province, Shaanxi province,~~final approval and ~~Qinghai~~was not in effect. The MOJ Draft stipulates that private schools using internet technology to provide online diploma-awarding educational courses shall obtain the private school operating permit of ~~Hainan province have promulgated their local regulations~~similar academic education at the same level, as well as the internet operating permit. The institutions that use internet technology to provide training and educational activities, vocational qualification and vocational skills training, or providing an internet technology service platform for the above activities, would need to obtain the corresponding internet operating permit and file with the administrative department for education or the department of human resources and social security at the provincial level where the institution is domiciled, and such institutions shall not provide educational and teaching activities which requires the private school operating permit.

Pursuant to the Administrative Regulations on Educational Websites and Online and Distance Education Schools issued by the Ministry of Education on July 5, 2000, educational websites and online education schools may provide educational services in relation to higher education, elementary education, pre-school education, teaching education, occupational education, adult education, other education and public educational information services. “Educational websites” refer to organizations providing education or education-related information services to website visitors by means of a database or online education platform connected via the internet or an educational television station through an Internet Service Provider, or ISP. “Online education schools” refer to educational websites providing academic education services or training services with the issuance of various certificates. Setting up education websites and online education schools is subject to approval from relevant education authorities, depending on the specific types of education. Any educational website and online education school shall, upon the receipt of approval, indicate on its website such approval information as well as the approval date and file number.

On June 29, 2004, the State Council promulgated the Decision on Setting Down Administrative Licenses for the Administrative Examination and Approval Items Really Necessary to Be Retained, pursuant to which the administrative license for “online education schools” was retained, while the administrative license for “educational websites” was not retained. On January 28, 2014, the State Council promulgated the Decision on Abolishing and Delegating Certain Administrative Examination and Approval Items, pursuant to which the administrative approval for “online education schools” of higher education was abolished.

Notwithstanding these decisions formulated by the State Council, as the Administrative Regulations on Educational Websites and Online Education Schools were not explicitly abolished, in practice, certain local authorities continue to implement the approval requirement for setting up education websites and online education schools until February 3, 2016, when the State Council promulgated the Decision on Cancelling the Second Batch of 152 Items Subject to Administrative Examination and Approval by Local Governments Designated by the Central Government, explicitly withdrew the approval requirements for operating educational websites and online education schools as provided by the Administrative Regulations on Educational Websites and Online Education Schools, and reiterated the principle that administrative approval requirements may only be imposed in accordance with the PRC Administrative Licensing Law.

In December 2017, Shanghai Municipal Government promulgated the Management Methods of Classified Registration of Private Schools, the Setting Standards for Private Training Institutions of Shanghai, the Management Measures for the For-profit Private Training Institutions of Shanghai, and the Management Methods for the Non-Profit Private Training Institutions of ~~Shanghai (collectively, the “Shanghai Implementation Regulations”).~~Shanghai. In November 2018, Beijing Municipal Education Commission and Beijing Municipal Human Resources and Social Security Bureau jointly promulgated the Standards of Private Education and Training Institutions in Beijing (Provisional). Pursuant to these measures, any management measures and regulations applied to the institutions that provides training services only through the Internet will be further promulgated separately. These management measures and regulations have not yet been introduced as of the date of this annual report.

On June 27, 2002, the General Administration of Press and Publication, or GAPP (currently known as the State Administration of Press, Publication, Radio, Film and Television, or the SAPPRFT) and the MIIT jointly promulgated the Tentative Internet Publishing Administrative Measures, or the Internet Publishing Measures, which took effect on August 1, 2002. The Internet Publishing Measures require entities that engage in Internet publishing to obtain an Internet Publishing License for engaging in Internet publishing from the SAPPRFT.FIL may keep their corporate forms within five years.

The Online Publishing Provisions, taking effect as of March 10, 2016, superseded the Internet Publishing Measures. Compared with the Internet Publishing Measures, the Online Publishing Provisions set out more detailed provisions for online publishing activities, which mainly cover issues such as defining online publishing services, licensingregulations provide otherwise. In addition, foreign investors or FIEs are required to file information reports and approvals, the administrative and supervisory regime and legal liabilities. According to the Online Publishing Provisions, all online publishing services provided within the territory of China are subject to the Online Publishing Provisions, and an Internet Publishing Licenseforeign investment shall be obtained to provide online publishing services.

As the scope of online publication is broad, certain contents we post on our website, such as video-audio clips and course materials, may be deemed as online publications.

Television program productions and distribution businesses are mainly regulated by Regulations on Administration of Radio and Television, which came in to effect on August 11, 1997 and was recently amended on March 1, 2017, and the Administrative Regulations on Production and Operation of Radio and Television Program which came into effect on August 20, 2004.

In addition, any enterprise or individual that holds a Publication Business Operating License shall file with the relevant local counterpart of SAPPRFT that granted such license to it within 15 days since it begins to carry out any online publication distribution business.

The Measures for the Administration of Publication of Audio-Visual Programs through Internet or Other Information Network, or the Audio-Visual Measures, promulgated by the SAPPRFT, on July 6, 2004 and put into effect on October 11, 2004, apply to the activities relating to the opening, broadcasting, integration, transmission or download of audio-visual programs using internet or other information network. Under the Audio-Visual Measures, to engage in the business of transmitting audio-visual programs, a license issued by SAPPRFT is required, and “audio-visual programs (including audio-visual products of films and televisions)” is defined as the audio-visual programs consisting of movable pictures or sounds that can be listened to continuously, which are shot and recorded using video cameras, vidicons, recorders and other audio-visual equipment for producing programs. Foreign invested enterprises are not allowed to carry out such business. On ~~April 13, 2005,~~December 26, 2019, the State Council ~~promulgated~~published the ~~Certain Decisions on the Entry~~Implementation Rules of ~~the Non-state-owned Capital into the Cultural Industry. On July 6, 2005, five PRC governmental authorities, including the SAPPRFT, jointly adopted the Several Opinions on Canvassing~~ Foreign Investment into the Cultural Sector. According to these regulations, non-state-owned capital and foreign investors are not allowed to engage in the business of transmitting audio- visual programs through information networks. However, the Audio-Visual Measures was repealed according to the Administrative Provisions on Audio-Visual Program Service through Special Network and Directed Transmission that was promulgated by the SAPPRFT on May 4, 2016, effective as of June 1, 2016.

According to the Catalog of Classification of Telecommunication Businesses, or the 2016 MIIT Catalog, which published by MIIT on December 28, 2015 and took effect on March 1, 2016 and were amended on June 6, 2019, internet information services, which include information release and delivery services, information search and query services, information community platform services, information real-times interactive services, and information protection and processing services, are classified as a category of value-added telecommunication services. The Administrative Measures on Internet Information Services, or ICP Measures, also promulgated by the PRC State Council on September 25, 2000 and most recently amended on January 8, 2011, set forth more specific rules on the provision of ICP services. According to ICP Measures, any company that engages in the provision of commercial ICP services shall obtain a sub-category VAT License for Internet Information Services, or ICP License, from the relevant government authorities before providing any commercial internet content services within the PRC, and when the ICP services involve areas of news, publication, education, medical treatment, health, pharmaceuticals and medical equipment, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP License from the MIIT or its provincial level counterpart. Pursuant to the above-mentioned regulations, “commercial ICP services” generally refers to provision of specific information content, online advertising, web page construction and other online application services through internet for profit making purpose. Operating our online platform to provide information and services to our students is classified as commercial ICP services.

In addition to the Telecommunications Regulations and the other regulations set forth above, the provision of commercial internet information services on mobile internet apps is regulated by the Administrative Provisions on Mobile Internet Applications Information Services, which was promulgated by the Cyberspace Administration of China, or the CAC, on June 28, 2016 and came into effect on August 28, 2015. Under the Audio-Visual Program Provisions, “internet audio-visual program services” is defined as activities of producing, redacting and integrating audio-visual programs, providing them to the general public via internet, and providing service for other people to upload and transmit audio-visual programs, and1, 2016. The providers of mobile internet ~~audio-visual program services~~applications are ~~required~~subject to ~~obtain a License for Online Transmission of Audio-Visual Programs issued~~requirements under these provisions, including acquiring the qualifications and complying with other requirements provided by SAPPRFT, or complete certain registration procedures with SAPPRFT. Providers of internet audio-visual program services must be either state-owned or state-controlled entities, and the business to be carried out by such providers must satisfy the overall planning and guidance catalog for internet audio-visual program service determined by SAPPRFT. In a press conference jointly held by SAPPRFT and MIIT to answer questions relating to the Audio-Visual Program Provisions in February 2008, SAPPRFT and MIIT clarified that providers of internet audio-visual program services who engaged in such services prior to the promulgation of the Audio-Visual Program Provisions are eligible to re-register with the relevant authorities and continue their operation of internet audio-visual program services so long as those providers did not violate the relevant laws and regulations and being responsible for information security. We currently, through Beijing Sunlands, our PRC consolidated VIE, and its wholly owned subsidiary, Beijing Shangren Chongye Education Technology Co., Ltd., or Shangren Chongye, respectively, hold an ICP License. The ICP License of Beijing Sunlands is valid until July 2, 2024 and the ICP License of Shangren Chongye, is valid until April 2, 2025.

The Regulations on Administration of Foreign-Invested Telecommunications Enterprises, or the ~~past. On May 21, 2008, SAPPRFT issued~~FITE Regulations, which took effect on January 1, 2002 and latest amended on February 6, 2016, are the key regulations that regulate foreign direct investment in telecommunications companies in China. The FITE Regulations stipulate that, except as otherwise provided by MIIT, the foreign investor of a Notice on Relevant Issues Concerning Application and Approval of License for the Online Transmission of Audio-Visual Programs, which further sets out detailed provisions concerning the application and approval process regarding the License for Online Transmission of Audio-Visual Programs. The notice also states that providers of internet audio-visual program services that engaged in such services prior to the promulgationtelecommunications enterprise is prohibited from holding more than 50% of the ~~Audio-Visual Program Provisions are eligible to apply for the license so long as their violation of the laws and regulations is minor in scope and can be rectified~~equity interest in a ~~timely manner~~foreign-invested enterprise that provides value-added telecommunications services. In addition, for a foreign investor to acquire any equity interest in a business providing value-added telecommunications services in China, it must demonstrate a positive track record and ~~they have no records of violation during~~experience in providing such services.

On July 13, 2006, the ~~last three months prior to~~MIIT issued the ~~promulgation of the Audio-Visual Program Provisions. Further, on March 30, 2009, SAPPRFT promulgated the Notice~~Circular on Strengthening the Administration of the Content of Internet Audio-Visual Programs, which reiterates the pre-approval requirements for the audio-visual programs transmitted via the internet, including through mobile networks, where applicable, and prohibits certain types of internet audio-visual programs containing violence, pornography, gambling, terrorism, superstition or other similarly prohibited elements.

~~On April 1, 2010, SAPPRFT promulgated the Provisional Implementation of the Tentative Categories of Internet Audio-Visual Program~~Foreign Investment in Value-added Telecommunications Services, or the ~~Categories,~~MIIT Circular 2006, which ~~clarified~~requires that (i) foreign investors can only operate a telecommunications business in China through establishing a telecommunications enterprise with a valid telecommunications business operation license; (ii) domestic license holders are prohibited from leasing, transferring or selling telecommunications business operation licenses to foreign investors in any form, or providing any resource, sites or facilities to foreign investors to facilitate the ~~scope~~unlicensed operation of ~~Internet audio-visual programs~~telecommunications business in China; (iii) value-added telecommunications services ~~which was amended on March 10, 2017. According~~providers or their shareholders must directly own the domain names and registered trademarks they use in their daily operations; (iv) each value-added telecommunications services provider must have the necessary facilities for its approved business operations and maintain such facilities in the geographic regions covered by its license;

and all value-added telecommunications services providers should improve network and information security, enact relevant information safety administration regulations and set up emergency plans to ensure network and information safety. The provincial communications administration bureaus, as local authorities in charge of regulating telecommunications services, (i) are required to ensure that existing qualified value-added telecommunications service providers will conduct a self-assessment of their compliance with the MIIT Circular 2006 and submit status reports to the ~~Categories,~~MIIT before November 1, 2006; and (ii) may revoke the value-added telecommunications business operation licenses of those that fail to comply with the above requirements or fail to rectify such noncompliance within specified time limits. Due to the lack of any additional interpretation from the regulatory authorities, it remains unclear what impact MIIT Circular 2006 will have on us or the other PRC internet companies with similar corporate and contractual structures. After the MOFCOM and NDRC amended the Catalog in March 2015, MIIT also issued the Circular on Removing the Restrictions on Shareholding Ratio Held by Foreign Investors in Online Data Processing and Transaction Processing (Operating E-commerce) Business on June 19, 2015, which amended the relevant provision in FITE Regulations by allowing foreign investors to own more than 50% of the equity interest in an operator of e-commerce business. However, foreign investors continue to be prohibited from holding more than 50% of the equity interest in a provider of other categories of value-added telecommunications services except fore-commerce, domestic multi-party communication, store-and-forward, and call center.

To comply with the above-mentioned foreign ownership restrictions, we operate our online platform in China through Beijing Sunlands and its wholly owned subsidiary, Shangren Chongye, all of the shareholders of Beijing Sunlands are PRC domestically funded entities, and Beijing Sunlands is controlled by Wuhan Zhibo, our PRC subsidiary, through a series of contractual arrangements. Beijing Sunlands and Shangren Chongye are the holders of the domain names, trademarks and facilities necessary for daily operations of our online platforms in compliance with the MIIT Circular 2006. Based on our PRC legal counsel’s understanding of the current PRC law, rules and regulations, the contractual arrangements among Wuhan Zhibo, Beijing Sunlands and its shareholders and subsidiaries are valid, binding and enforceable under current PRC law. However, we were further advised by our PRC legal counsel that there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. The third sub-category to the second category covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. However, there are still significantsubstantial uncertainties ~~relating~~with respect to the interpretation and ~~implementation~~application of ~~the Audio-Visual Program Provisions, in particular, the scope of “internet audio-visual programs.”~~

~~The~~existing or future PRC ~~Constitution states that PRC law protects the freedom and privacy of communications of citizens and prohibits infringement of these rights. In recent years, PRC government authorities have enacted~~ laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with the opinions of our PRC legal counsel.

On March 18, 1995, the PRC National People’s Congress promulgated the Education Law of the PRC, or the Education Law, which was further amended on ~~internet use~~August 27, 2009 and on December 29, 2018, stipulates that the government formulates plans for the development of education, establishes and operates schools and other types of educational institutions, and in principle, enterprises, institutions, social organizations and individuals are encouraged to ~~protect personal information from any unauthorized disclosure. According~~operate schools and other types of educational organizations. Comparing to the version of Education Laws that was amended and came into effect on 2009, which provided that no organization or individual may establish or operate a school or any other educational institution for commercial purposes, the current Education Law onnarrowed the ~~Protection~~provision prohibiting the establishment or operation of ~~Consumer Rights~~schools or other educational institutions for commercial purposes to only restricting a school or other educational institution founded with governmental funds or donated assets in the amended EducationLaw.

The Law for Promoting Private Education and Interests promulgated in 1993 and amended in 2013, business operators shall collect and use the personal information of consumers in a lawful and proper manner by following the principle that information collection or use is genuinely necessary. They shall expressly state the purposes, methods and scope of information collection or use, and obtain the consentits Implementing Rules

The Decision of ~~consumers collected, and shall not divulge, sell or illegally provide others with the same. Pursuant to the Decision on Strengthening the Protection of Online Information issued by~~ the Standing Committee of the National People’s Congress on Amending the Law for Promoting Private Education of the PRC, or the Amendment, has been promulgated by Order No. 55 of the President of the PRC on November 7, 2016 and came into force on September 1,2017.

On December ~~28, 2012~~29, 2016, the State Council issued the Several Opinions of the State Council on Encouraging the Operation of Education by Social Forces and Promoting the Healthy Development of Private Education, or the State Council

On December 30, 2016, the MOE, Ministry of Civil Affairs, State Administration for Industry and Commerce (the predecessor of the State Administration for Market Regulation), the Ministry of Human Resources and Social Welfare and the ~~Order~~State Commission Office of Public Sectors Reform jointly issued the Implementation Rules on the Classification Registration of Private Schools to reflect the new classification system for private schools as set out in the Amendment. Generally, if a private school established before promulgation of the Amendment chooses to register as a non-profit school, it shall amend its articles of association, continue its operation and complete the new registration process. If such private school chooses to register as a for-profit school, it shall conduct financial liquidation process, have the property rights of its assets such as lands, school buildings and net balance being authenticated by relevant government authorities, pay up relevant taxes, apply for a new private school operating permit, re-register as for-profit school and continue its operation. Specific provisions regarding the above registrations are yet to be introduced by people’s governments at the provinciallevel.

On December 30, 2016, the MOE, State Administration for Industry and Commerce and the Ministry of Human Resources and Social Welfare jointly issued the Implementation Rules on the Supervision and Administration of For-profit Private Schools, pursuant to which the establishment, division, merger and other material changes of a for-profit private school shall first be approved by the education authorities or the authorities in charge of labor and social welfare, and then be registered with the competent branch of State Administration for Industry and Commerce. In addition, it also provides that for-profit private training institutes shall be analogically governed by these Implementation Rules on the Supervision and Administration of For-profit Private Schools.

On August 10, 2018, the Ministry of Justice, or MOJ, published the draft amendment to the Regulations on the Implementation of the Law for Promoting Private Education of the PRC, or MOJ Draft, for public comment. As of the date of this annual report, this MOJ Draft is still pending for final approval and was not in effect. The MOJ Draft stipulates that private schools using internet technology to provide online diploma-awarding educational courses shall obtain the private school operating permit of similar academic education at the same level, as well as the internet operating permit. The institutions that use internet technology to provide training and educational activities, vocational qualification and vocational skills training, or providing an internet technology service platform for the ~~Protection~~above activities, would need to obtain the corresponding internet operating permit and file with the administrative department for education or the department of ~~Telecommunication~~human resources and ~~Internet User Personal Information~~social security at the provincial level where the institution is domiciled, and such institutions shall not provide educational and teaching activities which requires the private school operating permit.

The MOJ Draft further stipulates that the establishment of private training and educational organizations enrolling students of kindergarten, primary school, middle and high school age and providing activities relating to cultural and educational courses at school, or examination-related and further education-related tutoring and other cultural and educational activities, shall obtain a private school operating permit from the administrative departments for education of the governments at or above the county level. The establishment of private training and educational organizations that provide activities aiming at quality promotion, personality development in the areas of linguistic competence, arts, physical activities, technology, and activities targeting at cultural education for adults and non-degree continuing education, can apply to register as the legal person directly, however, such private training and/or educational organizations shall not carry out the cultural and educational activities mentioned above, which requires a private school operating permit. In addition, entities implementing group-based education shall not control non-profit schools by merger, acquisition, franchise or contractual arrangements.

Uncertainties exist with respect to the interpretation and application of the existing and future laws and regulations governing online private education industry, as well as when and how the MOJ Draft would come into effect and how the local government would promulgate implementing rules relating to the specific requirements applicable to online education service providers like us. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.”

On March 15, 2019, the Standing Committee of the National People’s Congress ~~has~~ published the Foreign Investment Law, or the FIL, which ~~will become~~became effective on January 1, 2020. The FIL is expected to replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The existing foreign-invested enterprises established prior to the effective of the FIL may keep their corporate forms within five years. ~~The implementing rules of the FIL will be stipulated separately by State Council.~~ Pursuant to the FIL, “foreign investors” means natural person, enterprise, or other organization of a foreign country, “foreign-invested enterprises” (FIEs) means any enterprise established under PRC law that is wholly or partially invested by foreign investors and “foreign investment” means any foreign investor’s direct or indirect investment in mainland China, including: (i) establishing FIEs in mainland China either individually or jointly with other investors; (ii) obtaining stock shares, stock equity, property shares, other similar interests in Chinese domestic enterprises; (iii) investing in new projects in mainland China either individually or jointly with other investors; and (iv) making investment through other means provided by laws, administrative regulations, or State Council provisions.

According to the Catalog of Classification of Telecommunication Businesses, or the 2016 MIIT Catalog, which published by MIIT on December 28, 2015 and took effect on March 1, 2016 and were amended on June 6, 2019, internet information services, which include information release and delivery services, information search and query services, information community platform services, information real-times interactive services, and information protection and processing services, are classified as a category of value-added telecommunication services. The Administrative Measures on Internet Information Services, or ICP Measures, also promulgated by the PRC State Council on September 25, 2000 and most recently amended on January 8, 2011, set forth more specific rules on the provision of ICP services. According to ICP Measures, any company that engages in the provision of commercial ICP services shall obtain a sub-category VAT License for Internet Information Services, or ICP License, from the relevant government authorities before providing any commercial internet content services within the PRC, and when the ICP services involve areas of news, publication, education, medical treatment, health, pharmaceuticals and medical equipment, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP License from the MIIT or its provincial level counterpart. Pursuant to the above-mentioned regulations, “commercial ICP services” generally refers to provision of specific information content, online advertising, web page construction and other online application services through internet for profit making purpose. Operating our online platform to provide information and services to our students is classified as commercial ICP services.

and all value-added telecommunications services providers should improve network and information security, enact relevant information safety administration regulations and set up emergency plans to ensure network and information safety. The provincial communications administration bureaus, as local authorities in charge of regulating telecommunications services, (i) are required to ensure that existing qualified value-added telecommunications service providers will conduct a self-assessment of their compliance with the MIIT Circular 2006 and submit status reports to the MIIT before November 1, 2006; and (ii) may revoke the value-added telecommunications business operation licenses of those that fail to comply with the above requirements or fail to rectify such noncompliance within specified time limits. Due to the lack of any additional interpretation from the regulatory authorities, it remains unclear what impact MIIT Circular 2006 will have on us or the other PRC internet companies with similar corporate and contractual structures. After the MOFCOM and NDRC amended the Catalog in March 2015, MIIT also issued the Circular on Removing the Restrictions on Shareholding Ratio Held by Foreign Investors in Online Data Processing and Transaction Processing (Operating E-commerce) Business on June 19, 2015, which amended the relevant provision in FITE Regulations by allowing foreign investors to own more than 50% of the equity interest in an operator of e-commerce business. However, foreign investors continue to be prohibited from holding more than 50% of the equity interest in a provider of other categories of value-added telecommunications services except fore-commerce, domestic multi-party communication, store-and-forward, and call center.

To comply with the above-mentioned foreign ownership restrictions, we operate our online platform in China through Beijing Sunlands and its wholly owned subsidiary, Shangren Chongye, all of the shareholders of Beijing Sunlands are PRC domestically funded entities, and Beijing Sunlands is controlled by Wuhan Zhibo, our PRC subsidiary, through a series of contractual arrangements. Beijing Sunlands and Shangren Chongye are the holders of the domain names, trademarks and facilities necessary for daily operations of our online platforms in compliance with the MIIT Circular 2006. Based on our PRC legal counsel’s understanding of the current PRC law, rules and regulations, the contractual arrangements among Wuhan Zhibo, Beijing Sunlands and its shareholders and subsidiaries are valid, binding and enforceable under current PRC law. However, we were further advised by our PRC legal counsel that there are substantial uncertainties with respect to the interpretation and application of existing or future PRC laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with the opinions of our PRC legal counsel.

The Law for Promoting Private Education of the PRC became effective on September 1, 2003 and was last amended on December 29, 2018, and the Implementation Rules for the Law for Promoting Private Education, or PE Implementation Rules of the PRC became effective on April 1, 2004.

The Decision of the Standing Committee of the National People’s Congress on Amending the Law for Promoting Private Education of the PRC, or the Amendment, has been promulgated by Order No. 55 of the President of the PRC on November 7, 2016 and came into force on September 1,2017.

On December 30, 2016, the MOE, Ministry of Civil Affairs, State Administration for Industry and Commerce (the predecessor of the State Administration for Market Regulation), the Ministry of Human Resources and Social Welfare and the State Commission Office of Public Sectors Reform jointly issued the Implementation Rules on the Classification Registration of Private Schools to reflect the new classification system for private schools as set out in the Amendment. Generally, if a private school established before promulgation of the Amendment chooses to register as a non-profit school, it shall amend its articles of association, continue its operation and complete the new registration process. If such private school chooses to register as a for-profit school, it shall conduct financial liquidation process, have the property rights of its assets such as lands, school buildings and net balance being authenticated by relevant government authorities, pay up relevant taxes, apply for a new private school operating permit, re-register as for-profit school and continue its operation. Specific provisions regarding the above registrations are yet to be introduced by people’s governments at the provinciallevel.

On August 10, 2018, the Ministry of Justice, or MOJ, published the draft amendment to the Regulations on the Implementation of the Law for Promoting Private Education of the PRC, or MOJ Draft, for public comment. As of the date of this annual report, this MOJ Draft is still pending for final approval and was not in effect. The MOJ Draft stipulates that private schools using internet technology to provide online diploma-awarding educational courses shall obtain the private school operating permit of similar academic education at the same level, as well as the internet operating permit. The institutions that use internet technology to provide training and educational activities, vocational qualification and vocational skills training, or providing an internet technology service platform for the above activities, would need to obtain the corresponding internet operating permit and file with the administrative department for education or the department of human resources and social security at the provincial level where the institution is domiciled, and such institutions shall not provide educational and teaching activities which requires the private school operating permit.

The MOJ Draft further stipulates that the establishment of private training and educational organizations enrolling students of kindergarten, primary school, middle and high school age and providing activities relating to cultural and educational courses at school, or examination-related and further education-related tutoring and other cultural and educational activities, shall obtain a private school operating permit from the administrative departments for education of the governments at or above the county level. The establishment of private training and educational organizations that provide activities aiming at quality promotion, personality development in the areas of linguistic competence, arts, physical activities, technology, and activities targeting at cultural education for adults and non-degree continuing education, can apply to register as the legal person directly, however, such private training and/or educational organizations shall not carry out the cultural and educational activities mentioned above, which requires a private school operating permit. In addition, entities implementing group-based education shall not control non-profit schools by merger, acquisition, franchise or contractual arrangements.

Uncertainties exist with respect to the interpretation and application of the existing and future laws and regulations governing online private education industry, as well as when and how the MOJ Draft would come into effect and how the local government would promulgate implementing rules relating to the specific requirements applicable to online education service providers like us. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.”

In December 2017, Shanghai Municipal Government promulgated the Management Methods of Classified Registration of Private Schools, the Setting Standards for Private Training Institutions of Shanghai, the Management Measures for the For-profit Private Training Institutions of Shanghai, and the Management Methods for the Non-Profit Private Training Institutions of Shanghai.

Pursuant to these measures, any management measures and regulations applied to the institutions that provides training services only through the Internet will be further promulgated separately. These management measures and regulations have not yet been introduced as of the date of this annual report.

On February 17, 2011, the Ministry of Culture, or MOC, promulgated the Interim Administrative Provisions on Internet Culture, or the Internet Culture Provisions, which became effective on April 1, 2011 and was further amended on December 15, 2017. The Internet Culture Provisions require ICP services providers engaging in commercial “internet culture activities” to obtain an Internet Culture Business Operating License from the MOC. “Internet cultural activities” is defined in the Internet Culture Provisions as an act of provision of internet cultural products and related services, which includes (i) the production, duplication, importation, and broadcasting of the internet cultural products; (ii) the online dissemination whereby cultural products are posted on the internet or transmitted via the internet to end-users, such as computers, fixed-line telephones, mobile phones, television sets and games machines, for online users’ browsing, use or downloading; and (iii) the exhibition and comparison of the internet cultural products.

The Internet Publishing Measures require entities that engage in Internet publishing to obtain an Internet Publishing License for engaging in Internet publishing from the SAPPRFT. Pursuant to the Internet Publishing Measures, the definition of “Internet publishing” is broad and refers to the act by ICP services providers to select, edit and process works created by themselves or others and subsequently post such works on the internet or transmit such works to the users’ end through internet for the public to browse. The “works” as defined under the Internet Publishing Measures include (i) contents from books, newspapers, periodicals, audio-visual products, electronic publications that have already been formally published or works that have been made public in other media, and (ii) all other edited or processed works of literatures, art, natural science, social science, engineering technology,etc.

The Online Publishing Provisions, taking effect as of March 10, 2016, superseded the Internet Publishing Measures. Compared with the Internet Publishing Measures, the Online Publishing Provisions set out more detailed provisions for online publishing activities, which mainly cover issues such as defining online publishing services, licensing and approvals, the administrative and supervisory regime and legal liabilities. According to the Online Publishing Provisions, all online publishing services provided within the territory of China are subject to the Online Publishing Provisions, and an Internet Publishing License shall be obtained to provide online publishing services. Pursuant to the Online Publishing Provisions, “online publishing services” refer to providing online publications to the public through information networks; and “online publications” refer to digital works with publishing features such as having been edited, produced or processed and are made available to the public through information networks, including: (i) written works, pictures, maps, games, cartoons, audio/video reading materials and other original digital works containing useful knowledge or ideas in the field of literature, art, science or other fields; (ii) digital works of which the content is identical to that of any published book, newspaper, periodical, audio/video product, electronic publication or the like; (iii) network literature databases or other digital works, derived from any of the aforesaid works by selection, arrangement, collection or other means; and (iv) other types of digital works as may be determined by the SAPPRFT. As the scope of online publication is broad, certain contents we post on our website, such as video-audio clips and course materials, may be deemed as online publications.

Television program productions and distribution businesses are mainly regulated by Regulations on Administration of Radio and Television, which came in to effect on August 11, 1997 and was recently amended on March 1, 2017, and the Administrative Regulations on Production and Operation of Radio and Television Program which came into effect on August 20, 2004.

Any enterprise or individual that engages in retail of publications shall obtain a Publication Business Operating License issued by the local counterpart of SAPPRFT at the county level. In addition, any enterprise or individual that holds a Publication Business Operating License shall file with the relevant local counterpart of SAPPRFT that granted such license to it within 15 days since it begins to carry out any online publication distribution business.

The Measures for the Administration of Publication of Audio-Visual Programs through Internet or Other Information Network, or the Audio-Visual Measures, promulgated by the SAPPRFT, on July 6, 2004 and put into effect on October 11, 2004, apply to the activities relating to the opening, broadcasting, integration, transmission or download of audio-visual programs using internet or other information network.

Foreign invested enterprises are not allowed to carry out such business. On April 13, 2005, the State Council promulgated the Certain Decisions on the Entry of the Non-state-owned Capital into the Cultural Industry. On July 6, 2005, five PRC governmental authorities, including the SAPPRFT, jointly adopted the Several Opinions on Canvassing Foreign Investment into the Cultural Sector. According to these regulations, non-state-owned capital and foreign investors are not allowed to engage in the business of transmitting audio-visual programs through information networks. However, the Audio-Visual Measures was repealed according to the Administrative Provisions on Audio-Visual Program Service through Special Network and Directed Transmission that was promulgated by the SAPPRFT on May 4, 2016, effective as of June 1, 2016.

To further regulate the provision of audio-visual program services to the public via the internet, including through mobile networks, within the territory of the PRC, the SAPPRFT and the MIIT jointly promulgated the Administrative Provisions on Internet Audio-Visual Program Service, or the Audio-Visual Program Provisions, on December 20, 2007, which came into effect on January 31, 2008 and was latest amended on August 28, 2015. Under the Audio-Visual Program Provisions, “internet audio-visual program services” is defined as activities of producing, redacting and integrating audio-visual programs, providing them to the general public via internet, and providing service for other people to upload and transmit audio-visual programs, and providers of internet audio-visual program services are required to obtain a License for Online Transmission of Audio-Visual Programs issued by SAPPRFT, or complete certain registration procedures with SAPPRFT. Providers of internet audiovisual program services must be either state-owned or state-controlled entities, and the business to be carried out by such providers must satisfy the overall planning and guidance catalog for internet audio-visual program service determined by SAPPRFT. In a press conference jointly held by SAPPRFT and MIIT to answer questions relating to the Audio-Visual Program Provisions in February 2008, SAPPRFT and MIIT clarified that providers of internet audio-visual program services who engaged in such services prior to the promulgation of the Audio-Visual Program Provisions are eligible to re-register with the relevant authorities and continuetheir operation of internet audio-visual program services so long as those providers did not violate the relevant laws and regulations in the past. On May 21, 2008, SAPPRFT issued a Notice on Relevant Issues Concerning Application and Approval of License for the Online Transmission of Audio-Visual Programs, which further sets out detailed provisions concerning the application and approval process regarding the License for Online Transmission of Audio-Visual Programs. The notice also states that providers of internet audio-visual program services that engaged in such services prior to the promulgation of the Audio-Visual Program Provisions are eligible to apply for the license so long as their violation of the laws and regulations is minor in scope and can be rectified in a timely manner and they have no records of violation during the last three months prior to the promulgation of the Audio-Visual Program Provisions. Further, on March 30, 2009, SAPPRFT promulgated the Notice on Strengthening the Administration of the Content of Internet Audio-Visual Programs, which reiterates the pre-approval requirements for the audio-visual programs transmitted via the internet, including through mobile networks, where applicable, and prohibits certain types of internet audio-visual programs containing violence, pornography, gambling, terrorism, superstition or other similarly prohibited elements.

On March 17, 2010, SAPPRFT promulgated the Provisional Implementation of the Tentative Categories of Internet Audio-Visual Program Services, or the Categories, which clarified the scope of Internet audio-visual programs services, which was amended on March 10, 2017.

The third sub-category to the second category

covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. However, there are still significant uncertainties relating to the interpretation and implementation of the Audio-Visual Program Provisions, in particular, the scope of “internet audio-visual programs.”

Under Circular 37, a SPV refers to an offshore entity established or controlled, directly or indirectly, by PRC residents or entities for the purpose of seeking offshore financing or making offshore investment, using legitimate domestic or offshore assets or interests, while “round trip investment” refers to the direct investment in China by PRC residents or entities through SPVs, namely, establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. Circular 37 requires that, before making contribution into an SPV, PRC residents or entities are required to complete foreign exchange registration with the SAFE or its local branch. SAFE Circular 37 further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become a shareholder of such non-listed SPV, subject to registration with SAFE or its localbranch.

PRC residents or entities who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration before the implementation of Circular 37 shall register their ownership interests or control in such SPVs with SAFE or its local branch. An amendment to the registration is required if there is a material change in the SPV registered, such as any change of basic information (including change of such PRC residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. Failure to comply with the registration procedures set forth in Circular 37, or making misrepresentation on or failure to disclose controllers of foreign-invested enterprise that is established through round-trip investment, may result in restrictions on the foreign exchange activities of the relevant foreign-invested enterprises, including payment of dividends and other distributions, such as proceeds from any reduction in capital, share transfer or liquidation, to its offshore parent or affiliate, and the capital inflow from the offshore parent, and may also subject relevant PRC residents or entities to penalties under PRC foreign exchange administration regulations. On February 13, 2015, SAFE further promulgated the Circular on Further Simplifying and Improving the Administration of the Foreign Exchange Concerning Direct Investment, or SAFE Circular 13, which took

effect on June 1, 2015. This SAFE Circular 13 has amended SAFE Circular 37 by requiring PRC residents or entities to register with qualified banks rather than SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment orfinancing. SAFE Circular 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead, relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

Pursuant to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, or Circular 7, issued by SAFE in February 2012, employees, directors, supervisors and other senior management participating in any stock incentive plan of an overseas publicly listed company who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. If we fail to complete the SAFE registrations, such failure may subject us to fines and legal sanctions and may also limit our ability to contribute additional capital into our wholly foreign-owned subsidiary in China and limit such subsidiary’s ability to distribute dividends tous.

In addition, the State Administration for Taxation has issued certain circulars concerning employee share options or restricted shares. Under these circulars, the employees working in the PRC who exercise share options or are granted restricted shares will be subject to PRC individual income tax. The PRC subsidiaries of such overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options. If the employees fail to pay or the PRC subsidiaries fail to withhold their income taxes according to relevant laws and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

Regulations on ~~loans to and direct investment in the PRC entities by offshore holding companies~~Foreign Debt

According to the Implementation Rules for the Provisional Regulations on Statistics and Supervision of Foreign Debt promulgated by SAFE on September 24, 1997 and the Interim Provisions on the Management of Foreign Debts promulgated by SAFE, the NDRC and the ~~MOF~~Ministry of Finance and effective from March 1, 2003, loans by foreign companies to their subsidiaries in China, which accordingly are foreign-invested enterprises, are considered foreign debt, and such loans must be registered with the local branches of the SAFE. Under the provisions, the total amount of accumulated medium-term and long-term foreign debt and the balance of ~~short- term~~short-term debt borrowed by a foreign-invested enterprise is limited to the difference between the total investment and the registered capital of the foreign-invested enterprise.

According to applicable PRC regulations on foreign-invested enterprises, capital contributions from a foreign holding company to its PRC subsidiaries, which are considered foreign-invested enterprises, may only be made when approval by or registration with the MOFCOM or its local counterpart is obtained.

On January 1,12, 2017, PBOC promulgated Notice of the People’s Bank of China on Issues Concerning Macro Prudential Management of Full Scale Cross-border Financing or PBOC Circular 9. According to PBOC Circular 9, PBOC ~~establishes~~established a cross-broader financing regulation system based on the capital or net assets of the micro main body under macro prudential rules, and the legal entities and financial institutions established in PRC including the branches of foreign banks registered in China but excluding government financing vehicles and real estate enterprise, may carry out cross-border financing of foreign currency in accordance with relevant regulations of such system. PBOC Circular 9 provides that, among other things, the outstanding amount of the foreign currency for the entities in cross-border financing shall be limited to the Upper Limit of the Risk Weighted Balance of such entity, which shall be calculated according to the formula provided in PBOC Circular 9; the enterprise shall, after signing the contract for cross-border financing, but not later than three business days before the

withdrawal of the borrowing funds, file with the local branches of SAFE for the cross-border financing through SAFE’s capital project information system. PBOC Circular 9 also provides that during the one-year period started from January 11, 2017, foreign-invested enterprises may choose one method to carry out cross-broader financing in foreign currency either according to PBOC Circular 9 or according to the Interim Provisions on the Management of Foreign Debts. After the end of such one-year period, the method of foreign-invested enterprises to carry out cross-broader financing in foreign currency will be determined by PBOC and SAFE. To date, though the one-year period has expired, no further regulations or ~~guidances~~guidance promulgated by PBOC and SAFE in this regard.

~~In January 2008, the PRC~~The Enterprise Income Tax Law enacted by the National People’s Congress and the Implementing Rules of the Enterprise Income Tax Law promulgated by the State Council, or collectively, the PRC EIT Law, ~~took effect. The PRC EIT Law applies~~apply a uniform 25% enterprise income tax rate to both foreign-invested enterprises and domestic enterprises, except where tax incentives are granted to special industries and projects. Enterprises qualified as “High and New Technology Enterprises” are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. The preferential tax treatment continues as long as an enterprise can retain its “High and New Technology Enterprise” status. Enterprise income tax for qualified small profit enterprises shall be at a reduced tax rate of 20%. Under the PRC EIT Law and its implementation regulations, dividends generated from the business of a PRC subsidiary after January 1, 2008 and payable to its foreign investor may be subject to a withholding tax rate of 10% if the PRC tax authorities determine that the foreign investor is a non-resident enterprise, unless there is a tax treaty with China that provides for a preferential withholding tax rate. Distributions of earnings generated before January 1, 2008 are exempt from PRC withholding tax.

Under the PRC EIT Law, an enterprise established outside China with “de facto management bodies” within China is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. A circular issued by the State Administration of Taxation, or SAT, in April 2009 regarding the standards used to classify certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese enterprise groups and established outside of China as “resident enterprises,” or the SAT Circular 82, clarified that dividends and other income paid by such PRC “resident enterprises” will be considered PRC-source income and subject to PRC withholding tax, currently at a rate of 10%, when paid to non-PRC enterprise shareholders. The SAT Circular 82 also subjects such PRC “resident enterprises” to various reporting requirements with the PRC tax authorities. Under the implementation regulations to the PRC EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, the SAT Circular 82 specifies that certain PRC-invested overseas enterprises controlled by a Chinese enterprise or a Chinese enterprise group in the PRC will be classified as PRC resident enterprises if thefollowing are located or resided in the PRC: (i) senior management personnel and departments that are responsible for daily production, operation and management; (ii) financial and personnel decision making bodies; (iii) key properties, accounting books, the company seal, and minutes of board meetings and shareholders’ meetings; and (iv) half or more of the senior management or directors who have the voting rights.

Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC ~~enterprise.~~enterprise and certain other conditions are satisfied. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. ~~In August 2015, the State Administration of Taxation~~The SAT promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under ~~Tax~~ Treaties, or SAT Circular ~~60,~~35, which became effective on ~~November~~January 1, ~~2015.~~2020. SAT Circular 6035 provides that non-resident enterprises are not required to obtain ~~pre-approval~~preapproval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands HK may be able to benefit from the 5% withholding tax rate for the dividends it receives from ~~each of~~ Wuhan Zhibo and Tianjin Sunlands, if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular ~~60,~~35, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

On April 30, 2009, the Ministry of Finance and the SAT jointly issued the Notice on Issues Concerning Process of Enterprise Income Tax in Enterprise Restructuring Business, or Circular 59. On December 10, 2009, the SAT issued the Notice on Strengthening the Administration of the Enterprise Income Tax concerning Proceeds from Equity Transfers by Non-resident Enterprises, or Circular 698. Both Circular 59 and Circular 698 became effective retroactively as of January 1, 2008. By promulgating and implementing these two circulars, the PRC tax authorities have enhanced their scrutiny over the direct or indirect transfer of equity interests in a PRC resident enterprise by a non-resident~~enterprise.~~62

On February 3, 2015, the SAT issued the Announcement of the State Administration of Taxation on Several Issues Concerning the Enterprise Income Tax on Indirect Property Transfer by Non-resident Enterprises, or SAT Bulletin 7, to supersede the provisions in relation to the Indirect Transfer as set forth in Circular 698. SAT Bulletin 7 introduces a new tax regime that is significantly different from that under Circular 698. Public Notice extends its tax jurisdiction to ~~capture not only Indirect Transfer as set forth under Circular 698 but also~~ transactions involving the transfer of ~~immovable property in China and~~taxable assets ~~held under the establishment and place in China of a foreign company~~ through ~~the~~ offshore transfer of a foreign intermediate holding company. Pursuant to SAT Bulletin 7, ~~also addresses~~where a non-resident enterprise indirectly transfers properties such as equity in PRC resident enterprises without any justifiable business purposes and aiming to avoid the payment of enterprise income tax, such indirect transfer must be reclassified as a direct transfer of equity in PRC resident enterprise. To assess whether an indirect transfer of PRC taxable properties has reasonable commercial purposes, all arrangements related to the ~~equity interest~~indirect transfer must be considered comprehensively and factors set forth in ~~a foreign intermediate holding company widely.~~SAT Bulletin 7 must be comprehensively analyzed in light of the actual circumstances. In addition, SAT Bulletin 7 ~~provides clearer criteria than Circular 698 on how to assess reasonable commercial purposes and introduces~~has introduced safe ~~harbor scenarios applicable to~~harbors for internal group ~~restructurings. However, it also brings challenges to both~~restructurings and the ~~foreign transferor~~purchase and ~~transferee~~sale of ~~the Indirect Transfer as they have to make self- assessment on whether the transaction should be subject to PRC tax and to file or withhold the PRC tax accordingly.~~equity through a public securities market.

On October 17, 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or SAT Bulletin 37, which came into effect ~~and superseded Circular 698~~ on December 1, 2017. The SAT Bulletin 37 further clarifies the practice and procedure of the withholding of non-resident enterprise income tax. ~~Among other things, the SAT Bulletin 37 provides that:~~

Where non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being required to file a return and taxed under SAT Bulletin 7 and/or SAT Bulletin 37 and we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to establish that we should not be held liable for any obligations under SAT Bulletin 7 and/or SAT Bulletin 37.

As a result of the contractual arrangements above, Wuhan Zhibo and Tianjin Sunlands bear the economic risks and receive the economic benefits of our VIEs, hold the power in directing the significant activities of our VIEs, and are the primary beneficiary of our VIEs. Therefore, we have consolidated the financial results of our VIEs and their subsidiaries in our consolidated financial statements.

In the opinion of Tian Yuan Law Firm, our PRC legal counsel, the contractual arrangements among our wholly-owned PRC subsidiaries, our VIEs, our VIEs’ respective shareholders and our VIEs’ respective subsidiaries are valid, binding and enforceable under current PRC law.

However, these contractual arrangements may not be as effective in providing control as direct ownership. There are substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. For a description of the risks related to our corporate structure, please see “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Corporate Structure.”

Our current principal executive offices are located at Building 4-6, Chaolai Science Park, No. 36 Chuangyuan Road, Chaoyang District, Beijing, the People’s Republic of China. We maintain offices in Beijing, China, with an aggregate of approximately 24,436square meters. These facilities currently accommodate our management headquarters, as well as our sales and marketing, course and educational content development, and general and administrative activities. We also maintain offices in Wuhan, China, with an aggregate of approximately ~~35,738~~26,208 square meters, to support part of our sales and marketing activities. In addition, we maintain offices in Guangzhou, China, with an aggregate of approximately 11,448 square meters, to support our sales and marketing activities as well as general and administrative activities.

We lease all of the facilities that we currently occupy from independent third parties. We believe that the facilities that we currently lease are adequate to meet our needs for the foreseeable future.

You should read the following discussion together with our consolidated financial statements and the related notes included elsewhere in this annual report on Form 20-F. This discussion may contain forward-looking statements about our business and operations based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those we currently anticipate as a result of many factors, including those we describe under “Item 3.D. Risk Factors” and elsewhere in this annual report on Form 20-F.

We operate in China’s online post-secondary and professional education market, and our results of operations and financial condition are significantly affected by general factors affecting this market. Drivers for our growth include China’s rapid economic growth, continued urbanization, and rising per capita disposable income, all of which have allowed Chinese households, particularly working adults, to spend more disposable income on education. In addition, driven by a strong desire for employment, career promotion, salary increases and local residence qualification, post-secondary and professional education in China has grown rapidly in the past several years and is expected to continue to grow in the future.

Changes to China’s economy and GDP growth also have a material impact on the online post-secondary and professional education market. In addition, the industry we operate in is fragmented, and we face competition from traditional offline players. At the same time, our results are subject to changes in the regulatory regime governing China’s education industry, particularly uncertainties relating to online education services. The PRC government regulates various aspects of our business and operations, including the qualification and licensing requirements for entities that provide online education services and limitations on foreign investments in the online education industry.

Additionally, we believe that our results of operations and financial condition are also affected by ~~company- specific~~company-specific factors, including the factors discussed below.

Our ability to respond to the evolving industry landscape and drive student acceptance of online education format

As an online service provider, we benefited significantly from the increasing proliferation of the internet, in particular the mobile internet, in China. In recent years, driven by the increasing number of internet users and mobile penetration rates, China’s online education industry has experienced an annual growth of more than 20%. China’s online post-secondary and professional education market is expected to grow from approximately RMB33.6 billion in 2017 to RMB130.1 billion in 2022, representing a CAGR of 31.1%, according to a commissioned report prepared by iResearch in connection with our initial public offering. According to the same source, China’s online STE tutoring market is expected to grow from approximately RMB4.5 billion in 2017 to RMB44.7 billion in 2022, representing a CAGR of 58.3%.

We believe that the online education format, as compared to traditional in-person classroom teaching, is superior as it breaks down the time and location barriers of offline education format and offers students more a flexible, convenient and cost-effective alternative. As a result, online education format has become increasingly popular among students, taking away market share from traditional offline players. For this reason, we believe our ability to continue to grow our net revenues and gross billings significantly depends on our ability to continue to convert students to embrace online education formats over traditional offline education format.

Our ability to increase the number of our students and new student enrollments at optimal pricing

Our net revenues and gross billings primarily consist of tuition payments from our students and are therefore affected by the number of our students and new student enrollments and the pricing of our educational services.

~~Our net revenues~~In 2018, 2019 and ~~gross billings have grown significantly in recent years, primarily driven by~~2020, our new student enrollments were 526,014, 363,013 and 434,240, respectively, and the ~~increase in the number~~numbers of our students were 1,025,959, 1,039,733 and ~~new student enrollments. The number of our students increased from 382,805 in 2016 to 660,182 in 2017, and further increased to 1,025,959 in 2018.~~1,130,650, respectively. Our new student enrollments increased ~~from 188,733~~ in ~~2016~~2020 as compared to ~~387,878~~2019, primarily due to the increase in ~~2017~~professional skills and ~~further increased~~general interest courses catering to ~~526,014~~growing demands for diverse personal education. We are seeking to offer a broader range of courses, foster a more a social and entertaining learning experience, and use cutting-edge technologies, particularly AI, to improve students’ learning experience and outcomes which we believe would help to achieve positive results in ~~2018.~~ our new student enrollments in the long run. See “3.D. Risk Factors - Risks Related to Our Business - If we fail to manage our business growth effectively, the success of our business model will be compromised.”

Our ability to continue to increase the number of our students and new student enrollments is primarily driven by factors including the quality of our education services, the range and attractiveness of our course offerings, our brand reputation, our ability to convert leads into student enrollments cost-effectively, and the availability of loans from third-party credit providers to our students. See “Item 3. Key Information—3.D.Risk Factors—Risks Related to Our Business—We may face risks associated with the installment tuition payment plan we offer to our students.” Our ability to attract prospective students in target markets and expand our course offerings has a direct impact on maintaining growths in the number of our students and new student enrollments, which in turn is subject to several other factors largely beyond our control, including the perception of the effectiveness of online education as compared to offline, classroom-based courses and the popularity of the degrees, diplomas and professional certifications our students are pursuing.

Our pricing is affected by the overall demand, the prices and availability of competing courses, perception of the quality and effectiveness of our course offerings, and the income levels that our students expect to achieve upon passing the exams that they are pursuing through taking our courses.

We typically receive tuition from our students (or third-party credit providers in the case of students taking loans for their tuition) upfront at the time of sale of our course packages. The tuition we collect from a student is initially recorded as deferred revenue and is generally recognized proportionally throughout the duration of the programs that student has enrolled in. For the year ended December 31, ~~2018,~~2020, the weighted average length of our ~~degree- or~~degree-or diploma-oriented ~~post- secondary~~post-secondary courses was approximately 3130 months, and the weighted average length of our professional certification preparation and professional skills courses was approximately 209 months. As of December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our deferred ~~revenue~~revenues were ~~RMB727.6~~RMB3,286.0 million, ~~RMB2,110.4~~RMB3,228.8 million and ~~RMB3,286.0~~RMB3,024.4 million (US$~~477.9~~463.5 million), respectively.

We continually evaluate our mix of course length. As we make these evaluations, we may market and sell courses with shorter or longer durations in order to balance among various goals, including satisfying student needs, driving revenue growth, and improving visibility of future earnings, which may affect our ability to increase our net revenues on a continuous basis. For example, if we increase the percentage of courses with longer durations in our total course offerings, our net revenues for a given period may reduce as an increasing part of our revenues may be deferred and recognized across longer periods. Any material change in our mix of course length could have a significant impact on our results of operations.

We depend on our ability to sell and market our services in a cost-effective manner to maintain and improve our operating margins.

Sales and marketing expenses have historically represented a substantial ~~majority~~portion of our total operating expenses. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our sales and marketing expenses were ~~RMB503.6~~RMB2,152.8 million, ~~RMB1,351.8~~RMB1,792.3 million and ~~RMB2,152.8~~RMB2,123.6 million (US$~~313.1~~325.5 million), respectively. The increase in our sales and marketing expenses from 2019 to 2020 was mainly due to increases in (i) compensation expenses related to our sales and marketing personnel; and (ii) spending on branding and marketing activities, including more marketing promotion activities to diversify student acquisition channels. Our sales and marketing expenses are primarily composed of marketing spending and expenses incurred in relation to sales and marketing personnel. Our ability to lower our sales and marketing expenses as a percentage of gross billings depends on our ability to improve sales and marketing efficiency and leverage our existing brand value and word-of-mouth referrals in our sales and marketing efforts. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, our marketing effectiveness ratio, as measured by dividing our marketing spending by our gross billings, was ~~24.8%~~29.1%, ~~20.2%~~40.2% and ~~29.1%~~46.9%, respectively.

We have acquired many of our existing students through search engine marketing channels, mobile marketing channels and, to a lesser extent, offline channels. Further, we rely on a large sales force to provide counseling-oriented sales services to convert sales leads into enrollments. As such, the cost-effectiveness of our sales and marketing depends heavily on our ability to enhance returns from different marketing channels, as well as to improve the efficiency of our counseling-oriented sales activities. We also plan to further strengthen our mobile marketing endeavors, which we believe are particularly critical to attracting prospective students who are not yet aware of solutions available to satisfy their desire to pursue post-secondary and professional education. These initiatives have placed, and will continue to place, significant strains on our ability to sell and market our course offerings in an efficient and cost-effectivemanner.

We derive substantially all of our net revenues from tuition that we charge our students for the course packages that they purchase from us. In ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, we generated net revenues of ~~RMB418.9~~RMB1,974.0 million, ~~RMB970.2~~RMB2,193.9 million and ~~RMB1,974.0~~RMB2,203.8 million (US$~~287.1~~337.7 million), respectively.

We generally bill our students for the entire course tuition upfront at the time of sale of our course packages. The tuition we collect from a student is initially recorded as deferred revenue and is generally recognized proportionally over a weighted average period of 3130 months for our ~~degree- or~~degree-or diploma-oriented post-secondary courses and a weighted average period of 209 months for our professional certification preparation and professional skills courses for the year ended December 31, ~~2018.~~2020. As of December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, we had deferred revenue of ~~RMB727.6~~RMB3,286.0 million, ~~RMB2,110.4~~RMB3,228.8 million and ~~RMB3,286.0~~RMB3,024.4 million (US$~~477.9~~463.5 million), respectively. For a reconciliation of our gross billings and net revenues, see “—Non-GAAP Financial Measures.”

The following table sets forth a breakdown of our total net revenues for the years indicated:

We recorded cost of revenues of ~~RMB71.0~~RMB330.4 million, ~~RMB170.3~~RMB396.3 million and ~~RMB330.4~~RMB387.3 million (US$~~48.1~~59.4 million) in ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, respectively. ~~Our~~Compensation for teachers and mentors accounted for a significant portion of our cost of ~~revenues primarily consists of compensation for our teachers~~revenues. In 2018, 2019 and ~~mentors. In 2016, 2017 and 2018,~~2020, the labor costs that we recorded as cost of revenues were ~~RMB52.8~~RMB239.8 million, ~~RMB118.0~~RMB234.4 million and ~~RMB239.8~~RMB220.2 million (US$~~34.9~~33.8 million), respectively, accounting for ~~74.3%~~72.6%, ~~69.3%~~59.1% and ~~72.6%~~56.9%, respectively, of our cost of revenues for the same periods. Our cost of revenues also included exams and services expenses, teaching materials costs, insurance costs and live streaming and related equipment costs. See “Item 4. Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” We expect our cost of revenues to increase in an absolute amount in line with our expansion of business and student base growth.

Our operating expenses consist of sales and marketing expenses and, to a lesser extent, general and administrative expenses and product development expenses. The following table sets forth our operating expenses, in absolute amounts and as percentages of total operating expenses, for the years indicated:

In 2016 and 2017, our sales and marketing expenses primarily consisted of (i) salaries paid to our sales and marketing personnel employed by us; (ii) student acquisition expenses, which mainly include marketing spending for search engine marketing channels and mobile marketing channels and commissions for the sales and marketing personnel employed by us; and (iii) rentals of premises occupied by our sales and marketing personnel.

We started to incur business process outsourcing services fees in the second half of 2018 as we began to outsource certain of our sales and marketing functions to third-party service providers, with a goal to improve our operating efficiency and streamline our sales and marketing efforts.

~~The following table sets forth a breakdown of our sales and marketing expenses, in absolute amounts and as percentages of total sales and marketing expenses, for 2016 and 2017:~~

In the second half of 2018, with a goal to improve our operating efficiency and streamline our sales and marketing efforts, we began to outsource certain of our sales and marketing functions to third-party service providers and therefore started to incur business process outsourcing fees in relation to such outsourcing arrangements. These fees mainly include the amounts that we paid to such third-party service providers pursuant to the business process outsourcing agreements we entered into with them. In connection with this initiative, in 2018 we changed how the components of our sales and marketing expenses are presented, which we believe is better indicative of future trends in our sales and marketing expenses.

The following table sets forth a breakdown of our sales and marketing expenses, in absolute amounts and as percentages of total sales and marketing expenses, for ~~2018:~~the years indicated:

Our expenses incurred in relation to sales and marketing personnel consist of (i) salaries paid to our sales and marketing personnel employed by us; (ii) commissions for the sales and marketing personnel employed by us; and (iii) business process outsourcing service fees and commissions. We group these three items together as we believe that they are related to the size of our sales and marketing personnel. We also believe that this reflects how our management manages our sales and marketing efforts. The marketing spending includes expenses relating to our search engine marketing channels and mobile marketing channels.

~~Historically, we had~~We have historically incurred, and are expected to continue to incur, significant sales and marketing expenses as we invested substantially in our sales, branding and marketing efforts and expanding our sales and marketing team to increase student enrollments and gain market share. We expect our sales and marketing expenses to increase in the foreseeable future as we plan to further grow our student enrollments to strengthen our existing leadership in China’s post-secondary and professional education market.

Our general and administrative expenses primarily consist of (i) compensation for our senior executives and administrative personnel, (ii) rentals of premises occupied by our senior executives and administrative personnel, and (iii) administrative and other expenses. We expect our general and administrative expenses to ~~increase as we continue to incur additional costs as a result of operating as a public company.~~remain stable in the foreseeable future.

The following table sets forth our consolidated results of operations for the years indicated. This information should be read together with our consolidated financial statements and related notes included elsewhere in this annual report. The operating results in any period are not necessarily indicative of the results that may be expected for any future period.

Year Ended December 31, ~~2018~~2020 Compared to Year Ended December 31, ~~2017~~2019

Our net revenues ~~increased by 103.5% from RMB970.2~~were RMB2,203.8 million (US$337.7 million) in 2020, remaining relatively stable compared with RMB2,193.9 million in 2017 to RMB1,974.0 million (US$287.1 million) in 2018, mainly driven by the increase in our gross billings, which was in turn attributable to increases in both the number of our students and the number of our new student enrollments. The number of our students increased from 660,182 in 2017 to 1,025,959 in 2018 and the number of new student enrollments grew by approximately 35.6% from 387,878 in 2017 to 526,014 in 2018, primarily as a result of our increased investment in improving the quality of our course and educational content offerings and sales, branding and marketing spending.2019.

The decrease was mainly due to a decrease in the ~~enhanced level of~~ compensation expenses for ~~our faculty members, which mainly include~~ teachers and mentors ~~as we continued to attract new and retain our existing faculty members. The total amount of compensation for such personnel increased by 103.3%~~ from ~~RMB118.0~~RMB234.4 million in ~~2017~~2019 to ~~RMB239.8~~RMB220.2 million (US$~~34.9~~33.8 million) in ~~2018.~~2020, and a decrease in insurance-related costs incurred for our integrated online education service package purchased by students from RMB66.0 million in 2019 to RMB40.6 million (US$6.2 million) in 2020. The decrease in our cost of revenues was partially offset by an increase in expenses related to service fees to educational institutions from RMB52.5 million to RMB83.3 million (US$12.8 million) in 2020.

As a result of the foregoing, our gross profit increased by ~~105.5%~~1.1% from ~~RMB799.9~~RMB1,797.6 million in ~~2017~~2019 to ~~RMB1,643.6~~RMB1,816.5 million (US$~~239.1~~278.4 million) in ~~2018.

As of December 31, 2020, we deployed approximately 5,700 sales and marketing personnel in ~~turn~~conducting sales activities.

Our general and administrative expenses decreased by 24.2% from RMB363.3 million in 2019 to RMB275.4 million (US$42.2 million) in 2020, primarily due to the decrease in office and compensation expenses.

Our product development expenses decreased by 34.6% from RMB101.7 million in 2019 to RMB66.5 million (US$10.2 million) in 2020, The decrease was primarily due to ~~increased spending on search engine marketing channels and mobile marketing channels and (ii) an increase~~a decrease in the compensation expenses incurred related to our product and technology development personnel.

The increase was ~~in turn mainly~~primarily due to the value-added tax exemption of RMB156.5 million offered by the relevant authorities as part of the national COVID-19 relief effort.

As a result of the foregoing, our net loss increased by 9.1% from RMB395.2 million in 2019 to RMB431.0 million (US$66.1 million) in 2020.

Our net revenues increased by 11.1% from RMB1,974.0 million in 2018 to RMB2,193.9 million (US$315.1 million) in 2019, mainly driven by an increase in the number of students from 1,025,959 in 2018 to 1,039,733 in 2019. During the same period, our gross billings decreased by 26.6% from 3,214.4 million in 2018 to 2,358.5 million in 2019, as we continued to adjust our marketing strategy, including adopting softer marketing tactics, in light of cost efficiency concerns in student acquisition and uncertainty of macro-economic trends.

Our cost of revenues increased by 20.0% from RMB330.4 million in 2018 to RMB396.3 million (US$56.9 million) in 2019, primarily due to an increase in our insurance-related costs from RMB8.6 million in 2018 to RMB66.0 million (US$9.5 million) in 2019 as we began to offer a bundled services including an integrated online education service package with insurance coverage for tuition refund. The increase in our cost of revenues was partially offset by a slight decrease in the compensation for teachers and mentors by 2.3% from RMB239.8 million in 2018 to RMB234.4 million (US$33.7 million) in 2019.

As a result of the foregoing, our gross profit increased by 9.4% from RMB1,643.6 million in 2018 to RMB1,797.6 million (US$258.2 million) in 2019, and gross margin decreased from 83.3% in 2018 to 81.9% in 2019.

~~As a result of the foregoing, our net loss in 2018 was RMB927.0 million (US$134.8 million), compared to RMB918.7 million in 2017.~~

Our net revenues increased by 131.6% from RMB418.9 million in 2016 to RMB970.2 million in 2017, mainly driven by the increase in our gross billings, which was in turn attributable to increases in both the number of our new student enrollments and gross billings per new student enrollment. The number of new student enrollments grew by approximately 105.5% from 188,733 in 2016 to 387,878 in 2017, primarily as a result of our increased investment in improving the quality of our course and educational content offerings and sales, branding and marketing spending. Our gross billings per new student enrollment grew by 56.4% from RMB3,926.0 in 2016 to RMB6,140.5 in 2017, primarily as a result of increased new student enrollments in our associate diploma plus bachelor’s degree programs which charge higher tuition as well as our increased ability to charge higher tuition for other course packages as we continued to improve our service quality and gain popularity among students.

Our cost of revenues increased by 139.9% from RMB71.0 million in 2016 to RMB170.3 million in 2017, primarily due to the increase in the compensation for our faculty members, which mainly include teachers and mentors, as we continued to attract new and retain our existing faculty members. The total amount of compensation for such personnel increased by 123.6% from RMB52.8 million in 2016 to RMB118.0 million in 2017. The total number of our faculty was 399 and 809, respectively, as of December 31, 2016 and 2017.

As a result of the foregoing, our gross profit increased by 129.9% from RMB347.9 million in 2016 to RMB799.9 million in 2017. Our gross margin decreased from 83.1% in 2016 to 82.5% in 2017, primarily as a result of the share-based compensation included in cost of revenues incurred in 2017.

~~Our operating expenses increased by 184.6% from RMB607.0 million in 2016 to RMB1,727.6 million in 2017.~~

Our sales and marketing expenses increased by 168.4% from RMB503.6 million in 2016 to RMB1,351.8 million in 2017, mainly driven by increases in (i) salaries paid to our sales and marketing personnel, (ii) student acquisition expenses, which mainly included expenses relating to our online sales and marketing channels and commissions paid to our sales and marketing personnel, and (iii) share-based compensation expenses incurred in connection with options to purchase our ordinary shares granted to our sales and marketing personnel under our 2017 Plan. Employee compensation increased by 155.6% from RMB211.6 million in 2016 to RMB540.8 million in 2017, primarily as a result of the increase in the number of our sales and marketing personnel. As of December 31, 2016 and 2017, we had 2,359 and 7,254 sales and marketing personnel, respectively. Student acquisition expenses increased by 160.4% from RMB203.8 million in 2016 to RMB530.6 million in 2017, primarily driven by our increased spending on sales, branding and marketing activities, including investments in broadening our search engine and mobile application channels. We incurred share-based compensation included in sales and marketing expenses of RMB75.2 million in 2017, while we did not incur any such share-based compensation in 2016.

Our general and administrative expenses increased by 283.6% from RMB89.4 million in 2016 to RMB342.9 million in 2017, primarily due to increases in (i) share-based compensation expenses incurred in connection with ordinary shares and options to purchase our ordinary shares to our senior executives and key employees; and (ii) recruitment expenses and compensation for our senior executives and administrative staff, both of which were primarily attributable to the hiring of new senior executives in 2017.

Our product development expenses increased by 135.9% from RMB13.9 million in 2016 to RMB32.9 million in 2017, primarily due to the increase in the compensation for our course and educational content professionals and technology development personnel during the same periods. The compensation for our course and educational content professionals and technology development personnel which increased by 153.6% from RMB11.8 million in 2016 to RMB29.9 million in 2017.2019.

As a result of the foregoing, our net loss ~~increased~~decreased by ~~262.3%~~57.4% from ~~RMB253.6~~RMB927.0 million in ~~2016~~2018 to ~~RMB918.7~~RMB395.2 million (US$56.8 million) in ~~2017.~~2019.

We use gross billings and EBITDA, each a non-GAAP financial measure, in evaluating our operating results and for financial and operational decision-making purposes.

We define gross billings for a specific period as the total amount of cash received for the sale of course packages, net of the total amount of refunds paid in such period. For a more detailed discussion of our tuition refund policy, see “Item 4. Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” Our management uses gross billings as a performance measurement because we generally bill our students for the entire course tuition at the time of sale of our course packages and recognize revenue proportionally over a period.

EBITDA is defined as net loss excluding depreciation and amortization, interest expense, interest income, and income tax expenses. We believe that gross billings and EBITDA provide valuable insight into the sales of our course packages and the performance of our business.

These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, their respective most directly comparable financial measure prepared in accordance with GAAP. A reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP measure has been provided in the tables included below. Investors are encouraged to review the reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP financial measures. As gross billings and EBITDA have material limitations as analytical metrics and may not be calculated in the same manner by all companies, they may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider gross billings and EBITDA as a substitute for, or superior to, their respective most directly comparable financial measures prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.

We are incorporated in the Cayman Islands. Under the current law of the Cayman Islands, we are not subject to income or capital gains tax. In addition, dividend payments are not subject to withholding tax in the Cayman Islands.

Our wholly owned subsidiary in Hong Kong is subject to a two-tiered income tax rate for taxable income earned in Hong Kong with effect from April 1, 2018. The first HK$2 million of profits earned by Sunlands HK will be taxed at 8.25%, while the remaining profits will continue to be taxed at the existing 16.5% tax rate. Payments of dividends by our subsidiaries to us are not subject to withholding tax in Hong Kong.

Our subsidiaries and our consolidated VIEs and their subsidiaries in China are companies incorporated under PRC law and, as such, are subject to PRC enterprise income tax on their taxable income in accordance with the relevant PRC income tax laws. Pursuant to the PRC Enterprise Income Tax Law, ~~which became effective on January 1, 2008,~~or PRC EIT Law, a uniform 25% enterprise income tax rate is generally applicable to both ~~foreign- invested~~foreign-invested enterprises and domestic enterprises, except where a special preferential rate applies. For example, enterprises qualified as “High and New Technology Enterprises” are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. Pursuant to the Notice on Implementation of Inclusive Tax Relief Policy for Small and Low-profit Enterprises jointly issued by the Ministry of Finance and the SAT on January 17, 2019 and the Announcement on Issues Relating to Implementation of Inclusive Income Tax Relief Policy for Small and Low-profit Enterprises issued by SAT on January 18, 2019, during the period from January 1, 2019 to December 31, 2021, the portion of annual taxable income amount of a small and low-profit enterprise which does not exceed RMB1 million shall be computed at a reduced rate of 25% as taxable income amount, and be subject to a 20% enterprise income tax rate, and the portion of annual taxable income amount which exceeds RMB1 million but does not exceed RMB3 million shall be computed at a reduced rate of 50% as taxable income amount, and be subject to a 20% enterprise income tax rate. The enterprise income tax is calculated based on the entity’s global income as determined under PRC tax laws and accounting standards.

~~Prior to May 2016, our PRC subsidiaries were~~Our services are subject to ~~business tax and related surcharges~~VAT at athe rate of ~~3.36% and 5.6% on revenues related to educational services and non-educational services, respectively. Our net revenues are presented net of those taxes incurred.~~

~~Beginning in May 2016,~~6% for general-VAT-payer entities in accordance with ~~Tax~~tax rule, ~~(Cai Shui [2016] No. 68), the non-academic educational programs and services are~~except that certain subsidiaries were subject to a simple VAT collection method at a rate of 3%. Entities which are subject to the tax rate of 3% are not allowed to offset qualified input VAT paid to suppliers against their output VAT liabilities. Our educational services which were previously subject to business tax, are therefore subject to VAT at the rate of 6% for Tianjin Shangde and 3% for our other subsidiaries, VIEs and VIEs’ subsidiaries. The VAT rate applicable to our non-educational service is 6% before June 2019. Since January 2020, in accordance with ~~Tax rule, Cai Shui [2016] No. 36.~~Announcement of the Ministry of Finance and the SAT [2020] No.8 and Announcement of the Ministry of Finance and the SAT [2021] No.7, due to the Novel coronavirus (“COVID-19”) pandemic, the VAT on certain services was temporarily exempted until March 31, 2021.

As a Cayman Islands holding company, we may receive dividends from our PRC subsidiaries through Sunlands Online Education HK Limited. The PRC EIT Law and its implementing regulations provide that dividends paid by a PRC entity to a non-resident enterprise for income tax purposes is subject to PRC withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with China. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC ~~enterprise.~~enterprise and certain other conditions are met. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident

enterprise throughout the 12 months prior to receiving the dividends. ~~In August 2015, the~~The State Administration of Taxation promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under ~~Tax~~ Treaties, or SAT Circular ~~60,~~35, which became effective on ~~November~~January 1, ~~2015.~~2020. SAT Circular 6035 provides that ~~non-resident~~nonresident enterprises are not required to obtain pre-approval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands Online Education HK Limited may be able to benefit from the 5% withholding tax rate for the dividends it receives from ~~each of~~ Wuhan Zhibo and Tianjin Sunlands, if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular ~~60,~~35, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

If our holding company in the Cayman Islands or any of our subsidiaries outside of China were deemed to be a “resident enterprise” under the PRC EIT Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.”

We prepare our financial statements in accordance with U.S. GAAP, which requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. We continually evaluate these judgments and estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and assumptions that we believe to be reasonable, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

The selection of critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing our financial statements. We believe the following accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements. You should read the following description of critical accounting policies, judgments and estimates in conjunction with our consolidated financial statements and other disclosures included in this annual report.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This standard replaced existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. The ASU also includes guidance regarding the accounting for contract acquisition costs, which includes sales commissions. We have early adopted the new standard as of January 1, 2017 using the full retrospective method which requires us to present our financial statements for all periods as if Topic 606 had been applied to all prior periods. We did not apply practical expedients as provided under Topic 606.

We follow five steps for ~~our~~ revenue recognition under ~~Topic~~ASC 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Our revenue is reported net of discount, ~~business tax,~~ value added tax and related surcharges. The primary sources of our revenues are as follows:

For online education services, we provide an integrated online education service package to students, including online live streaming audio-video interactive course content, recorded previous live audio-video course content, quiz banks, online chat rooms, and educational contents. The services and goods provided in the package are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming and recorded courses which are not distinct and are not sold standalone. Therefore, our integrated online education services package is accounted for as a single performance obligation. The weighted average service period for degree- or diploma-oriented post-secondary courses and professional certification preparation and professional skills courses was 3130 months and 209 months, respectively, for the year ended December 31, ~~2018.~~2020.

The transaction price of the integrated online education service package is determined by the contract amount net of any discounts. Students are offered a full, unconditional refund within 24 hours upon ~~enrollment, and a partial refund for the~~enrollment. Prior to June 2019, undelivered courses were eligible for refund, excluding registration fees, within 7 ~~days.~~days after enrollment. For course contracts entered after June 2019, undelivered courses are eligible for refund during the entire service period, excluding registration fees.

~~Online~~Revenues for online education services ~~consist of two types of revenue models—the non-refundable course model and the refundable course model. Revenues for the non-refundable course model~~ are recognized on a straight line basis over the service period from the registration day to the day on which the service period ends.

For certain online courses, we provided students the ~~refundable course model, we provide a student the ability~~right to apply for a refund or cash incentive if ~~the student achieves~~ certain ~~agreed conditions.~~pre-agreed conditions are achieved. We ~~estimate~~estimated the variable consideration to be earned to the extent it iswas probable that a significant reversal of cumulative revenue recognized ~~will~~would not occur when the uncertainty associated with the variable consideration iswas resolved and ~~recognizes~~recognized revenue over time from the registration day to the day on which the service period ~~ends~~ended on a straight line basis. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price ~~are~~were based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that iswas reasonably available.

~~Under the non-refundable course model, for~~For certain online courses, the service period includes a regular period plus an extended period. We offer students an extended service period after the regular period if certain pre-agreed conditions are met. Based on historical passing rates, and forecasted passing rates due to continuous improvement of service ~~equality,~~quality, we apply and categorize the students by portfolio (1) eligible to extended period and (2) not eligible to extended period and estimates the portion of each portfolio. We recognize the revenue on each portfolio over time from the registration day to the day on which the service is expected to end on a straight line basis.

For certain online courses, we offer ~~students~~ a bundled service including an integrated online education service package with insurance coverage for tuition refund. If ~~the refundable~~certain refund conditions are met, students could claim the insurance equal to ~~the~~ full or partial amount of the service fee. We identify that the integrated online education service package and the insurance service are two separate performance obligations as students ~~can~~ benefit from each service on its own and they are separately identifiable in the contract. We record revenue generated from online education services with insurance coverage on a gross basis as we are acting as the principal to ~~fulfil~~fulfill all obligation and control all the services transferred to the students.

~~We estimate the standalone~~ The total service fee is allocated to each performance obligation based on selling prices, ~~of each performance obligation~~which are estimated based on the expected cost of satisfying each performance obligation plus an estimated ~~margin for each performance obligation.~~margin. Revenues for integrated online education service and the insurance ~~coverage~~ service are recognized ~~based on their relative stand-alone selling price~~ over their respective service periods on a straight line basis from the registration day to the day on which the service period ends as the students simultaneously ~~receive~~receives and ~~consume~~consumes the benefits provided by these two performance obligations.

Our deferred costs represent the unamortized incremental sales commission relating to obtaining of ~~customers~~customer contract, and the contract liability primarily consists of deferred revenue.

We offer an installment payment option to students, under which the students obtain loans, from accredited credit sources (“("Loan ~~Companies”~~Companies") for the purpose of satisfying the ~~student’s~~student's tuition payment due. The borrowing student is obligated to repay the loan principal in installments over periods ranging from ~~three~~3 months to 1218 months to the Loan Companies, while we agree with the Loan Companies to bear the ~~student’s~~student's interest expense and service fees. The Loan Companies remit the tuition to us for students to complete the registration. The interest expense and service fees are recorded as a reduction of the transaction price.

We earn commission revenue by providing referral services to third party ~~education~~ institutions. Commission revenue is recognized at the point in time when the referred students ~~registered~~complete registration at the third party ~~education~~ institutions, ~~and the tuition fees are paid,~~ by when the performance obligation of us is satisfied.

Revenues related to our online courses are recognized over time. Deferred revenue consists of tuition fees received from students for which services have not yet been provided to students.

Our consolidated financial statements include the financial statements of Sunlands Technology Group, its subsidiaries, its VIEs and the VIEs’ subsidiaries. All profits, transactions and balances among Sunlands Technology Group, its subsidiaries, its VIEs and the VIEs’ subsidiaries have been eliminated upon consolidation.

PRC laws and regulations restrict foreign ownership in value-added telecommunication services and other internet-related business. As ~~Wuhan Zhibo and Tianjin Sunlands~~a Cayman Islands company, we are deemed asa foreign legal person under PRC ~~laws,~~laws. Accordingly, our wholly owned subsidiaries in the PRC, as foreign invested companies, are not eligible to engage in the ~~provision of online education~~value-added telecommunications services. ~~Due to~~To comply with these foreign ownership restrictions, we conduct our online education service business in China ~~primarily~~partially through a series of contractual ~~arrangements~~agreements among ~~(i) Wuhan Zhibo,~~ our wholly owned PRC ~~subsidiary, Beijing Sunlands,~~subsidiaries, our ~~VIE,~~VIEs and the shareholders of ~~Beijing Sunlands~~the VIEs, including exclusive technical consultation and service agreements, business operation agreements, equity interest pledge agreements, option agreements, powers of attorney and spousal consent letters. Through the contractual agreements, we have (i) the power to direct the activities that most significantly affect the economic performance of the VIEs, and (ii) ~~Tianjin Sunlands, our wholly owned PRC subsidiary, Tianjin Shangde, our VIE, and shareholders~~the right to receive the economic benefit of ~~Tianjin Shangde.~~the VIEs that could potentially be significant to the VIEs. As a result, ~~of these contractual arrangements,~~ the shareholders of ~~our~~the VIEs ~~irrevocably granted each of Wuhan Zhibo and Tianjin Sunlands~~lack the power to ~~exercise all voting rights to which they were entitled. In addition, Wuhan Zhibo has~~direct the ~~option to acquire all~~activities of the ~~equity interests in Beijing Sunlands~~VIEs that most significantly impact the entity's economic performance, the obligation to absorb the expected losses, and ~~Tianjin Sunlands has~~ the ~~option~~right to ~~acquire all~~receive the expected residual returns of the equity interests in Tianjin Shangde, to the extent permitted by the then-effective PRC laws and regulations, for nominal consideration. Finally, Wuhan Zhibo and Tianjin Sunlands are entitled to receive service fees for certain services to be provided to the VIEs in an amount at their discretion. We concluded that Beijing Sunlands and Tianjin Shangde are our VIEs, of whichentity. Accordingly, we are considered as the primary ~~beneficiary. As such, we consolidate the results of operations~~beneficiary of the VIEs, and we have consolidated the financial results of our VIEs and our VIEs’ subsidiaries in our consolidated financial statements.

As advised by Tian Yuan Law Firm, our PRC legal counsel, the contractual arrangements among our ~~corporate structure in China complies with all existing~~wholly-owned PRC ~~laws~~subsidiaries, our VIEs, our VIEs’ respective shareholders and ~~regulations.~~our VIEs’ respective subsidiaries are valid, binding and enforceable under current PRC law. However, our PRC legal counsel has also advised us that as there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations, and we cannot assure you that the PRC government would agree that our corporate structure or any of the above contractual arrangements comply with current or future PRC laws or regulations. PRC laws and regulations governing the validity of these contractual arrangements are uncertain and the relevant government authorities may have broad discretion in interpreting these laws and regulations.

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when it, in the opinion of us, is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized. The impact of an uncertain income tax position is recognized at the largest amount that is ~~more-likely- than-not~~more-likely-than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes.

Prior to our initial public offering, we were a private company with no quoted market prices for our ordinary shares. We therefore needed to make estimates of the fair value of our ordinary shares at various dates for the purpose of determining the fair value of our ordinary shares at the date of the grant of share-based compensation awards to our employees as one of the inputs into determining the grant date fair value of the award.

~~The following table sets forth the fair value of our ordinary shares estimated at different times prior to our initial public offering with the assistance from an independent valuation firm:~~

The valuations of our ordinary shares were performed using methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants Audit and Accounting Practice Aid Series: ~~Valuation of Privately-Held-Company Equity Securities Issued as Compensation~~, or the AICPA Practice Guide. The determination of the fair value of our ordinary shares requires complex and subjective judgments to be made regarding our projected financial and operating results, our unique business risks, the liquidity of our shares and our operating history and prospects at the time of valuation. The option-pricing method was used to allocate our equity value to preferred shares or other senior securities and ordinary shares, taking into account the guidance prescribed by the AICPA Practice Guide. This method treats ordinary shares and preferred shares or other senior securities as call options on the equity value, with exercise prices based on their respective payoffs upon a liquidity event.

In determining our equity value, we applied the discounted cash flow analysis based on our projected cash flow using our best estimate as of the valuation date. The major assumptions used in calculating the fair value of our equity include:

~~The fair value of the options granted prior to our initial public offering is estimated on the dates of grant using the binomial option pricing model with the following assumptions used.~~

Subsequent to our initial public offering, the market price of our publicly traded ADSs is used as an indicator of fair value of our ordinary shares for purposes of recording share-based compensation in connection with the equity awards granted pursuant to the 2017 Plan.

Share-based compensation with employees is measured based on the grant date fair value of the equity instrument. Share-based compensation expenses, net of forfeitures, are recognized over the requisite service period based on a straight-line basis with a corresponding impact reflected in additional paid-in capital.

~~Share-based compensation awards which require the issuance of a variable number of shares to settle a fixed monetary amount are accounted for as liabilities.~~

In October 2017, the shareholders of Sunlands Cayman approved the 2017 Plan under which we were authorized to grant a maximum of 483,846 ordinary shares. All of the ordinary shares reserved and issuable upon the exercise of options granted pursuant to the 2017 Plan shall, upon issuance of such ordinary shares, be designated as Class C ordinary shares.

On October 20, 2017, Sunlands Cayman granted: (i) 363,452 options in Sunlands Cayman under the 2017 Plan for an exercise price of US$0.0047 (equivalent to RMB0.0312) (“Scheme I”), and (ii) 66,053 options in Sunlands Cayman under the 2017 Plan for an exercise price of US$84.75 (equivalent to RMB560.95) (“Scheme II”).

The options under Scheme I of the 2017 Plan shall be vested and become exercisable immediately at the grant date. We recorded compensation expenses of RMB205.7 million under Scheme I of the 2017 Plan for the year ended December 31, 2017 in the consolidated financial statements of Sunlands Cayman.

The options under Scheme II of the 2017 Plan shall be vested and become exercisable in the installments of 10%, 20%, 30% and 40%, respectively, on the first, second, third and fourth anniversary of the date of our initial public offering. The vesting and exercisability of options granted under Scheme II of the 2017 Plan are both upon our initial public offering which is not assessed as probable until the effective date of the initial public offering. Therefore, no share-based compensation expenses were accrued under Scheme II of the 2017 Plan for the year ended December 31, 2017. Upon the completion of our initial public offering in March 2018, a compensation expense of RMB2.8 million was recorded for the year ended December 31, 2018.

On May 17, 2018, our board of directors approved the payment of compensation to certain independent directors for their services rendered for the year ended December 31, 2018. The payment will be settled by issuing a variable number of our shares valued at RMB1.1 million and the share number is determined by dividing such fixed amount by the average closing price during certain periods of time. We accounted for the share-based payment awards to the independent directors as liabilities which was included in accrued expenses and other current liabilities.

On August 24, 2018, our board of director approved an additional 345,503 ordinary shares be reserved for future issuance under the 2017 Plan. All of the ordinary shares reserved and issuable upon the exercise of options granted pursuant to the 2017 Plan shall, upon issuance of such ordinary shares, be designated as Class C ordinary shares.

~~We recorded share-based compensation expenses of nil, RMB288.8 million and RMB3.9 million (US$0.6 million), respectively, for the years ended December 31, 2016, 2017 and 2018.~~

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows:

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterment that extends the useful lives of property and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidated statements of operations.

Share-based compensation awards which require the issuance of a variable number of shares to settle a fixed monetary amount are recorded as liabilities.

The detailed discussion on recent accounting pronouncements is included in note 2 to our audited consolidated financial statements, which are included in this annual report on Form 20-F.

Our principal sources of liquidity have been cash generated from operating activities and, to a lesser extent, proceeds from the issuance and sale of our ordinary shares. As of December 31, ~~2018,~~2020, we had ~~RMB1,248.8~~RMB760.7 million (US$~~181.6~~116.6 million) in cash and cash equivalents, the majority of which were held by our Cayman Island holding company, PRC subsidiaries and VIEs and VIEs’ subsidiaries in China. Our cash and cash equivalents consist primarily of bank deposits. Our cash and cash equivalents are primarily denominated in U.S. dollars. We believe that our current cash and anticipated cash flow from operations will be sufficient to meet our anticipated cash needs, including our cash needs for working capital and capital expenditures, for at least the next 12 months. We believe there is no substantial doubt to operate as a going concern, as a result, the accompanying consolidated financial statements have been prepared on a going concern basis, and do not reflect

any adjustments relating to the recoverability and reclassification of assets and liabilities that might have been necessary if we were unable to continue as a going concern.

We incurred net losses of ~~RMB253.6~~RMB927.0 million, ~~RMB918.7~~RMB395.2 million and ~~RMB927.0~~RMB431.0 million (US$~~134.8~~66.1 million), respectively, for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018.~~2020. We ~~had negative working capital (which is the difference between current assets and current liabilities) of RMB367.2 million and RMB535.6 million as of December 31, 2016 and 2017, respectively, and we~~ had positive working capital of RMB268.5 million as of December 31, 2018, negative working capital of RMB195.4 million as of December 31, 2019 and negative working capital of RMB641.4million (US$~~39.1~~98.3 million) as of December 31, ~~2018. For the years ended December 31, 2016 and 2017, the~~2020. The major factor for our negative working capital position as of December 31, 2019 and 2020 was deferred revenue.

We intend to finance our future working capital requirements and capital expenditures from cash generated from operating activities and funds raised from financing activities. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet our requirements, we may seek to issue debt or equity securities or obtain additional credit facilities. Financing may be unavailable in the amounts we need or on terms acceptable to us, if at all. Issuance of additional equity securities, including convertible debt securities, would dilute our earnings per share. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. If we are unable to obtain additional equity or debt financing as required, our business operations and prospects may suffer.

As a holding company with no material operations of our own, we conduct our operations primarily through subsidiaries and consolidated VIEs in China. We are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries in China through capital contributions or loans, subject to the approval of government authorities and limits on the amount of capital contributions and loans. In addition, our subsidiaries in China may provide Renminbi funding to our consolidated VIEs only through entrusted loans. The ability of our subsidiaries in China to make dividends or other cash payments to us is subject to various restrictions under PRC laws and regulations. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our

Sunlands Technology Group is a holding company with no material operations of its own. We conduct our operations primarily through our subsidiaries and our consolidated VIEs in China. As a result, our ability to pay dividends depends upon dividends paid by our subsidiaries. If our subsidiaries or any newly formed subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us.

In addition, our subsidiaries in China are permitted to pay dividends to us only out of their retained earnings, if any, as determined in accordance with the Accounting Standards for Business Enterprise as promulgated by the Ministry of Finance of the PRC, or PRC GAAP. In accordance with PRC company laws, our consolidated VIEs in China must make appropriations from their after-tax profit to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of our consolidated VIEs. Appropriation to discretionary surplus fund is made at the discretion of our consolidated VIEs. Pursuant to the law applicable to China’s foreign investment enterprise, our subsidiaries that are foreign investment enterprise in the PRC have to make appropriation from their after-tax profits, as determined under PRC GAAP, to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the reserve fund has reached 50% of the registered capital of our subsidiary. Appropriation to the other two reserve funds are at our subsidiary’s discretion.

As an offshore holding company, we are permitted under PRC laws and regulations to provide funding from the proceeds of our offshore fund raising activities to our PRC subsidiaries only through loans or capital contributions, and to our consolidated affiliated entity only through loans, in each case subject to the satisfaction of the applicable government registration and reporting, approval requirements. As a result, there is uncertainty with respect to our ability to provide prompt financial support to our PRC subsidiaries and consolidated VIEs when needed. Notwithstanding the foregoing, our PRC subsidiaries may use their own retained earnings (rather than Renminbi converted from foreign currency denominated capital) to provide financial support to our consolidated affiliated entity either through entrustment loans from our PRC subsidiaries to our consolidated VIEs or direct loans to such consolidated affiliated entity’s nominee shareholders, which would be contributed to the consolidated variable entity as capital injections. Such direct loans to the nominee shareholders would be eliminated in our consolidated financial statements against the consolidated affiliated entity’s share capital.

We have focused on and will continue to invest in our technology system, which supports all key aspects of our online platform and is designed to optimize for scalability and flexibility. See “Item 4. Information on the Company—4.B. Business Overview—IT Infrastructure and Capabilities.”

Other than as disclosed elsewhere in this annual report on Form 20-F, we are not aware of any trends, uncertainties, demands, commitments or events for the year ended December 31, ~~2018~~2020 that are reasonably likely to have a material and adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed financial information to be not necessarily indicative of future results of operations or financial condition.

We did not have any off-balance sheet arrangements as of December 31, ~~2018.~~2020.

The following table sets forth our contractual obligations as of December 31, ~~2018:~~2020:

Our Board of Directors consists of ~~nine~~seven directors, including ~~three~~two independent directors, namely Mr. ~~Sam Hanhui Sun, Mr. Michael Minhong Yu~~Yifan Li and Mr. ~~Xiaochuan Wang.~~Zheng Zhao. A director is not required to hold any shares in our company to qualify to serve as a director. The Corporate Governance Rules of the NYSE generally require that a majority of an issuer’s board of directors must consist of independent directors. However, the Corporate Governance Rules of the NYSE permit foreign private issuers like us to follow “home country practice” in certain corporate governance matters. We rely on this “home country practice” exception and do not have a majority of independent directors serving on our Board of Directors.

A director who to his knowledge is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with our company is required to declare the nature of his or her interest at a meeting of our directors. A general notice given to the directors by any director to the effect that (i) he is a member or officer of any specified company or firm and is to be regarded as interested in any contract or transaction with that company or firm, or (ii) he is to be regarded as interested in any contract or transaction which may, after the date of such notice, be made with a specified person who is connected with him, shall be deemed a sufficient declaration of interest for the purposes of voting on a resolution in respect to a contract or transaction in which he/she has an interest. A director may vote in respect of any contract or proposed contract or arrangement notwithstanding that he may be interested therein and if he does so, his vote shall be counted and he may be counted in the quorum at any meeting of the directors at which any such contract or proposed contract or arrangement is considered, subject to any separate requirement for Audit Committee approval under applicable laws or the rules of the New York Stock Exchange, and unless disqualified by the chairman of the relevant board meeting. OurBoard of Directors may exercise all of the powers of our company to borrow money, to mortgage or charge its undertaking, property and assets (present and future) and uncalled capital, and to issue debentures, bonds and other securities whenever money is borrowed or as security for any debt, liability or obligation of our company or of any third party. None of our directors has a service contract with us that provides for benefits upon termination of service as a director.

We have established an audit committee, a compensation committee and a nominating and corporate governance committee under our Board of Directors. We have adopted a charter for each of the three committees. Each committee’s members and functions are described below.

Our audit committee consists of Mr. ~~Sam Hanhui Sun, Mr. Michael Minhong Yu~~Yifan Li and Mr. ~~Xiaochuan Wang,~~Zheng Zhao, and is chaired by Mr. ~~Sam Hanhui Sun.~~Yifan Li. We have determined that each of Mr. ~~Sam Hanhui Sun, Mr. Michael Minhong Yu~~Yifan Li and Mr. ~~Xiaochuan Wang~~Zheng Zhao satisfies the requirements of Section 303A of the Corporate Governance Rules of the NYSE and meet the independence standards under Rule 10A-3 under the Securities Exchange Act of 1934, as amended. We have determined that Mr. ~~Sam Hanhui Sun~~Yifan Li qualifies as an “audit committee financial expert.” The audit committee oversees our accounting and financial reporting processes and the audits of our financial statements. The audit committee is also responsible for, among other things:

Our compensation committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. ~~Michael Minhong Yu~~Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. ~~Michael Minhong Yu~~Zheng Zhao satisfies the “independence” requirements of Section 303A of the Corporate Governance Rules of the NYSE.

Our nominating and corporate governance committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. ~~Michael Minhong Yu,~~Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. ~~Michael Minhong Yu~~Zheng Zhao satisfies the “independence” requirements of Section 303A of the Corporate Governance Rules of the NYSE. The nominating and corporate governance committee assists our Board of Directors in selecting individuals qualified to become our directors and in determining the composition of our Board of Directors and its committees. The nominating and corporate governance committee is also responsible for, among otherthings:

Under Cayman Islands law, our directors owe fiduciary duties to our company, including a duty of loyalty, a duty to act honestly and a duty to act in what they consider in good faith to be in our best interests. Our directors must also exercise their powers only for a proper purpose. Our directors also owe to our company a duty to exercise the skill they actually possess and such care and diligence that a reasonable prudent person would exercise in comparable circumstances. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than may reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended and restated from time to time. Our company has the right to seek damages if a duty owed by our directors is breached. In limited exceptional circumstances, a shareholder may have the right to seek damages in our name if a duty owed by our directors is breached. The functions and powers of our Board of Directors include, among others, (i) convening shareholders’ annual general meetings and reporting its work to shareholders at such meetings, (ii) declaring dividends, (iii) appointing officers and determining their termsof offices and responsibilities, and (iv) approving the transfer of shares of our company, including the registering of such shares in our share register.

Our officers are elected by and serve at the discretion of the board. Each director is not subject to a term of office and holds office until such time as his successor takes office or until the earlier of his death, resignation or removal from office by ~~special~~ordinary resolution of the shareholders. A vacancy on the board created by the removal of a director may be filled by ordinary resolution or by the ~~unanimous~~affirmative vote of a simple majority of the remaining directors present and voting at a board meeting. Mr. Peng Ou shall have the right to appoint or remove any Management Director (as defined under our fourth amended and restate memorandum and articles of association) by delivering a written ~~resolution of all shareholders.~~notice to our company, provided that the Founder shall not be entitled to exercise such right if he or his affiliates do not hold any shares. A director will be removed from office automatically if, among other things, the director (i) becomes bankrupt or makes any arrangement or composition with his creditors; (ii) dies or is found by our company to be of unsound mind; (iii) resigns by notice in writing to our company; (iv) is prohibited by law or the rules of the New York Stock Exchange from being a director; or (v) is removed from office pursuant to any other provisions of our fourth amended and restated memorandum and articles ofassociation.

We had ~~3,076, 9,146~~3,847, 2,880 and ~~3,847~~7,347 full-time employees as of December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, respectively. As of December 31, ~~2018,~~2020, most of our employees were in Beijing, Guangzhou, Wuhan and Shenzhen.

The following table sets forth the number of our employees as of December 31, ~~2018:~~2020:

We enter into employment contracts with our full-time employees which contain standard confidentiality and non-compete provisions. In addition to salaries and benefits, we provide performance-based bonuses for our full-time employees and commission-based compensation for our sales and marketing force.

Under PRC law, we participate in various employee social security plans that are organized by municipal and provincial governments for our PRC-based full-time employees, including pension, unemployment insurance, childbirth insurance, work-related injury insurance, medical insurance and housing insurance. We are required under PRC law to make contributions from time to time to employee benefit plans for our PRC-based full-time employees at specified percentages of the salaries, bonuses and certain allowances of such employees, up to a maximum amount specified by the local governments in China.

We believe that we maintain a good working relationship with our employees, and we have not experienced any material labor disputes in the past. None of our employees are represented by labor unions.

The following table sets forth information concerning the beneficial ownership of our ordinary shares as of March 31, ~~2019~~2021 by:

The calculations in the table below are based on ~~6,840,335~~6,729,197 issued and outstanding ordinary shares as of March 31, ~~2019,~~2021, comprising (i) ~~1,751,660~~1,809,878 Class A ordinary shares, (ii) 826,389 Class B ordinary shares, and (iii) ~~4,262,286~~4,092,930 Class C ordinary shares.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days, including through the exercise of any option, warrant, or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

To our knowledge, as of March 31, ~~2019, 733,392~~2021, 899,503 of our Class A ordinary shares were held by one record holder in the United States, which was The Bank of New York Mellon, the depositary of our ADR program. The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of record holders of our ordinary shares in the United States.

We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

~~In October 2017, we disposed a subsidiary to Shangde Jiaxun with a total consideration of RMB1,000 and a gain of RMB178 was recorded in our consolidated statement of operations.~~

We have appended consolidated financial statements filed as part of this annual report on Form 20-F.

From time to time, we may become a party to various legal or administrative proceedings arising in the ordinary course of our business. We are currently not a party to, and we are not aware of any threat of, any legal or administrative proceedings that, in the opinion of our management, are likely to have any material and adverse effect on our business, financial condition, cash flow or results of operations.

In June 2019, we, and certain of our current and former directors and officers and our underwriters in our initial public offering were named as defendants in a securities class action filed in the U.S. District Court for the Eastern District of New York. Amended complaints in this class action were filed in November 2019. The action, purportedly brought on behalf of a class of persons who allegedly suffered damages as a result of their trading in the ADSs, alleges that our registration statement on Form F-1 in connection with our March 2018 initial public offering contains material misstatements and omissions in violation of the U.S. federal securities laws. We filed a motion to dismiss the action in March 2020, which was denied by an order dated March 31, 2021. We are currently unable to estimate the potential loss, if any, associated with the resolution of the lawsuit. We intend to defend the actions vigorously. For risks and uncertainties relating to pending cases against us, see “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We and certain of our directors and officers have been named as defendants in several shareholder class action lawsuits, which could have a material adverse impact on our business, financial condition, results of operation, cash flows and reputation.”

We have not previously declared or paid cash dividends and we have no plan to declare or pay any dividends in the near future on our shares or the ADSs representing our Class A ordinary shares. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

We are ~~a holding~~an exempted company incorporated in the Cayman Islands. We rely principally on dividends from our PRC subsidiaries for our cash requirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to pay dividends to us. See “Item 4. Information on the Company—B.4.B. Business Overview—Regulation—Regulations on Foreign Exchange—Dividend Distribution.”

Our Board of Directors has discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. ~~In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our Board of Directors.~~ Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our Board of Directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the Class A ordinary shares underlying the ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to the ADS holders in proportion to the Class A ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder.

Except as otherwise disclosed in this report, we have not experienced any significant changes since the date of the annual financial statements included herein.

The ADSs representing our Class A ordinary shares have been listed on the New York Stock Exchange since March 23, 2018 under the symbol “STG.” Each 25 ADSs represent one Class A ordinary share, par value US$0.00005 per share.

The ADSs representing our Class A ordinary shares have been listed on the New York Stock Exchange since March 23, 2018 under the symbol “STG.”

The following are summaries of material provisions of our fourth amended and restated memorandum and articles of association and the Companies ~~Law (2018 Revision)~~Act (As Revised) of the Cayman Islands which we refer to as the “Companies ~~Law”~~Act” below insofar as they relate to the material terms of our ordinary shares.

General. Our authorized share capital is US$50,000 divided into 1,000,000,000 shares with a par value of US$0.00005 each, comprising (i) 796,062,195 Class A ordinary shares with a par value of US$0.00005 each, (ii) 826,389 Class B ordinary shares with a par value of US$0.00005 each, and (iii) 203,111,416 Class C ordinary shares with a par value of US$0.00005 each. Holders of ordinary shares have the same rights except for voting and conversion rights as set out in our fourth amended and restated memorandum and articles of association. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. We may not issue share to bearer. Our shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinaryshares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our Board of Directors subject to our fourth amended and restated memorandum and articles of association and the Companies ~~Law.~~Act. Our fourth amended and restated memorandum and articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies ~~Law.~~Act.

Voting Rights. In respect of all matters subject to shareholder vote, each Class A ordinary share is entitled to one vote, each Class B ordinary share is entitled to seven votes, and each Class C ordinary share is entitled to ten votes.

A quorum required for a meeting of shareholders consists of a majority of the votes attaching to the issued and outstanding shares entitled to vote at general meetings present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative. As a Cayman Islands exempted company, we are not obliged by the Companies ~~Law~~Act to call shareholders’ annual general meetings. Our fourth memorandum and articles of association provide that we may (but are not obliged to) in each year hold a general meeting as our annual general meeting in which case we will specify the meeting as such in the notices calling it, and the annual general meeting will be held at such time and place as may be determined by our directors. We, however, will hold an annual shareholders’ meeting during each fiscal year, as required by the Listing Rules at the NYSE. Each general meeting, other than an annual general meeting, shall be an extraordinary general meeting. Shareholders’ annual general meetings and any other general meetings of our shareholders may be called by a majority of our Board of Directors or our chairman and a majority of our Board of Directors or our chairman shall, upon requisition of shareholders holding not less 10% of all votes attaching to all issued and outstanding ordinary shares entitled to vote at general meetings, convene an extraordinary general meeting; however, our fourth amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders. Advance notice of at least fifteen (15) days is required for the convening of our annual general meeting and other general meetings unless such notice is waived in accordance with our articles of association.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting, while a special resolution also requires the affirmative vote of no less than two-thirds of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting. A special resolution will be required for important matters such as making changes to our fourth amended and restated memorandum and articles of association.

Transfer of Ordinary Shares. Subject to the restrictions in our fourth amended and restated memorandum and articles of association as set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our Board of Directors.

Our Board of Directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our Board of Directors may also decline to register any transfer of any ordinary share unless:

If our directors refuse to register a transfer of any share they shall, within two calendar months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NYSE, be suspended and the register closed at such times and for such periods as our Board of Directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year.

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them. Any distribution of assets or capital to a holder of ordinary share will be the same in any liquidation event.

Redemption, Repurchase and Surrender of Ordinary Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders thereof, on such terms and in such manner as may be determined, before the issue of such shares, by our Board of Directors. Our company may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our Board of Directors or are otherwise authorized by our fourth memorandum and articles of association. Under the Companies ~~Law,~~Act, the redemption or repurchase of any share may be paid out of our company’s profits or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if the company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies ~~Law~~Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding, or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

Variations of Rights of Shares. If at any time our share capital is divided into different classes or series of shares, the rights attached to any class or series of shares (unless otherwise provided by the terms of issue of the shares of that class or series), whether or not our company is being wound-up, may be varied with the consent in writing of a majority the holders of the issued shares of that class or series or with the sanction of an ordinary resolution at a separate meeting of the holders of

the shares of the class or series. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares.

Inspection of Books and Records. Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate ~~records.~~records (other than copies of our memorandum and articles of association, our register of mortgages and charges, and any special resolutions passed by our shareholders). However, we will provide our shareholders with annual audited financial statements. See “—10.H. Document on Display.”

Issuance of Additional Shares. Our fourth amended and restated memorandum and articles of association authorizes our Board of Directors to issue additional ordinary shares from time to time as our Board of Directors shall determine, to the extent of available authorized but unissued shares.

Our fourth amended and restated memorandum and articles of association also authorizes our Board of Directors to, ~~subject to~~without the approval byof our shareholders, establish from time to time one or more series of preferred shares and to determine, with respect to any series of preferred shares, the terms and rights of that series, including, among other things:

Our Board of Directors may issue preferred shares without action by our shareholders to the extent authorized but unissued. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Anti-Takeover Provisions. Some provisions of our fourth amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that authorize our Board of Directors to issue authorized preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

Exempted Company. We are an exempted company with limited liability under the Companies ~~Law.~~Act. The Companies ~~Law~~Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on that shareholder’s shares of the company.

We have not entered into any material contracts other than in the ordinary course of business and other than those described in this annual report on Form 20-F.

See “Item 4. Information of the Company—4.B. Business Overview—Regulation—Regulations Relating to Foreign Exchange.”

The following discussion of Cayman Islands, PRC and United States federal income tax consequences of an investment in the ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This discussion does not deal with all possible tax consequences relating to an investment in the ADSs or ordinary shares, such as the tax consequences under state, local and other tax laws. To the extent that the discussion relates to matters of Cayman Islands tax law, it represents the opinion of Maples and Calder (Hong Kong) LLP, our Cayman Islands counsel. To the extent that the discussion relates to matters of PRC tax law, it represents the opinion of Tian Yuan Law Firm, our PRC legal counsel.

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation, and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us or holders of our ADSs or ordinary shares levied by the government of the Cayman Islands, except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of the ADSs or ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the ADSs or ordinary shares, nor will gains derived from the disposal of the ADSs or ordinary shares be subject to Cayman Islands income or corporation tax.

Under the PRC EIT Law, which became effective on January 1, 2008 and amended on ~~February 24, 2017,~~December 29, 2018, an enterprise established outside the PRC with “de facto management bodies” within the PRC is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. Under the implementation regulations to the PRC EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise.

In addition, the SAT Circular 82 issued by the SAT in April 2009 specifies that certain offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups will be classified as PRC resident enterprises if the following are located or resident in the PRC: (a) senior management personnel and departments that are responsible for daily

production, operation and management; (b) financial and personnel decision making bodies; (c) key properties, accounting books, company seal, minutes of board meetings and shareholders’ meetings; and (d) half or more of the senior management or directors having voting rights. Further to SAT Circular 82, the SAT issued the SAT Bulletin 45, which took effect in September 2011, to provide more guidance on the implementation of SAT Circular 82. SAT Bulletin 45 provides for procedures and administration details of determination on resident status and administration on post-determination matters. Our company is a company incorporated outside the PRC. As a holding company, its key assets are its ownership interests in its subsidiaries, and its key assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside the PRC. As such, we do not believe that our company meets all of the conditions above or is a PRC resident enterprise for PRC tax purposes. For the same reasons, we believe our other entities outside of China are not PRC resident enterprises either. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” There can be no assurance that the PRC government will ultimately take a view that is consistent with us. If the PRC tax authorities determine thatour Cayman Islands holding company is a PRC resident enterprise for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. For example, a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders (including the ADS holders). In addition, non-resident enterprise shareholders (including ~~our~~ the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including

the ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.”

The following is a discussion of the material U.S. federal income tax consequences to the U.S. Holders described below of owning and disposing of ADSs or ordinary shares, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to acquire ADSs or ordinary shares. This discussion applies only to a U.S. Holder that holds ADSs or ordinary shares as capital assets for U.S. federal income tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including alternative minimum tax and Medicare contribution tax consequences, and tax consequences applicable to U.S. Holders subject to special rules, suchas:

If an entity that is classified as a partnership for U.S. federal income tax purposes owns ADSs or ordinary shares, the U.S. federal income tax treatment of its partners will generally depend on the status of such partners and the activities of the partnership. Partnerships owning ADSs or ordinary shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of ADSs or ordinary shares.

This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, and the income tax treaty between the United States and the PRC, or the Treaty, all as of the date hereof, any of which is subject to change, possibly with retroactive effect. This discussion is also based, in part, on representations by the Depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of ADSs or ordinary shares that for

The policy of our audit committee is to pre-approve all audit and non-audit services provided by Deloitte Touche Tohmatsu Certified Public Accountants LLP, our independent registered public accounting firm, including audit services and tax services as described above.

The following table sets forth information about our purchases of outstanding ADSs from August 29, 2018 to March 31, ~~2019.~~2021.

As a Cayman Islands exempted company listed on the New York Stock Exchange, we are subject to New York Stock Exchange corporate governance listing standards. However, New York Stock Exchange rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the New York Stock Exchange corporate governance listing standards. We currently follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the New York Stock Exchange that listed companies must have: (i) a majority of independent directors; (ii) a nominating/corporate governance committee composed entirely of independent directors; and (iii) a compensation committee composed entirely of independent directors. To the extent we choose to continue to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would enjoy under New York Stock Exchange corporate governance listing standards applicable to U.S. domestic issuers. See “Item 3. Key Information—3.D. Risk Factors— Risks Relating to the ADSs—As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the New York Stock Exchange corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the New York Stock Exchange corporate governance listing standards.”

The consolidated financial statements of Sunlands Technology Group are included at the end of this annual report.

The registrant hereby certifies that it meets all of the requirements for filing its annual report on Form 20-F and that it has duly caused and authorized the undersigned to sign this annual report on its behalf.

We have audited the accompanying consolidated balance sheets of Sunlands Technology Group, ~~(the "Company"), formerly known as Sunlands Online Education Group,~~ and its subsidiaries ~~its consolidated variable interest entities ("VIEs") and VIEs' subsidiaries (collectively the "Group"~~(the "Company") as of December 31, ~~2017~~2019 and ~~2018,~~2020, the related consolidated statements of operations, comprehensive loss, changes in shareholders' deficit and cash flows for each of the three years in the period ended December 31, ~~2018,~~2020, and the related notes and ~~the financial statement schedule listed in~~ Schedule I (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the ~~Group~~Company as of December 31, ~~2017~~2019 and ~~2018,~~2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, ~~2018,~~2020, in conformity with accounting principles generally accepted in the United States of America.

Our audits also comprehended the translation of Renminbi amounts into United States dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 2 to the financial statements. Such United States dollar amounts are presented solely for the convenience of readers outside the People’s Republic of China.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the ~~Group's~~Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

The accompanying notes are an integral part of the consolidated financial statements.

~~Note: The number of ordinary shares reflects the outstanding ordinary shares of the Company as if the Group’s 2017 reorganization took place on January 1, 2016.~~

The accompanying notes are an integral part of the consolidated financial statements.

Sunlands Technology Group (the “Company” or “Sunlands Technology”)~~, formerly known as Sunlands Online Education Group,~~ was incorporated under the laws of the Cayman Islands on September 18, 2015. The Company, its subsidiaries, its consolidated variable interest entities (“VIEs”) and VIEs’ subsidiaries (collectively the “Group”) are primarily engaged in providing online education ~~service~~services in the People’s Republic of China (“PRC”).

In July 2011, Mr. Jianhong Yin (the “Founder”) established Sunland Education Co. Limited (the “Previous Cayman”). In March 2012, the Previous Cayman, through its 100% owned subsidiary, Sunland Education Technology HK Limited, established Beijing Shangzhi Jiaye Education Technology Co., Ltd. (the “Previous WFOE”).

PRC laws and regulations currently require any foreign entity that invests in the education business in China to be an educational institution with relevant experience in providing education services outside China. To comply with the PRC laws and regulations, the Founder, Previous WFOE and Beijing Shangde Jiaxun Education Technology Co., Ltd. (“Shangde Jiaxun” or the “Previous VIE”), which was established by the Founder in July 2008, entered into a series of contractual arrangements in December 2013 (the “Previous VIE arrangement”). As a result of these contractual arrangements, the Previous Cayman believed that these contractual arrangements would enable itself to (1) have power to direct the activities that most significantly affects the economic performance of the Previous VIE, and (2) receive the economic benefits of the VIE that could be significant to the Previous VIE. Accordingly, the Previous Cayman was considered the primary beneficiary of the Previous VIE and was able to consolidate the Previous VIE and its subsidiaries.

In June 2014, the Group determined to cease the offline, classroom-based education service and transform its business model to online education service. During 2015 and 2016, in order to execute the business shift and prepare for an initial public offering (“IPO”) in the PRC, the Group terminated the Previous VIE arrangement and started to conduct the online education service through Beijing Shangde Online Education Technology Co., Ltd. (the “2016 Reorganization”). Beijing Sunlands was set up by Shangde Jiaxun in September 2013 as a limited liability company in the PRC.

In August 2017, the Group decided to pursue the IPO in the capital market overseas. To accommodate the aforementioned restrictions, the Group identified the Company as the prospective listing entity and entered into a series of contractual arrangements among the Company’s shareholders, its subsidiaries, the Founder, the Chief Executive Officer (the “CEO”) of the Group, Beijing Sunlands and the shareholders of Beijing Sunlands (the “2017 Reorganization”).

~~During 2015 and 2016, in part of the IPO plan in the PRC, the Group undertook a series of steps, mainly to dissolve the VIE structure, which includes:~~

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

As the Previous Cayman, Previous WFOE and Beijing Sunlands were all under common control of the Founder, the above series of steps to reorganize the Group during 2015 and 2016 were accounted for in a manner similar to a pooling of interest with assets and liabilities and were all reflected at their historical amounts in the Group’s consolidated financial statements.

~~In August 2017, the Group decided to pursue the IPO in the capital market overseas. Accordingly, the Group undertook a series of steps, mainly to establish the VIE structure, which includes:~~

As the Company, New WFOE and New VIE were all under common control of the Founder, the above series of steps to reorganize the Group during 2017 were accounted for in a manner similar to a pooling of interest with assets and liabilities at their historical amounts in the Group’s consolidated financial statements.

~~As such, the Group’s consolidated financial statements were prepared as if the current corporate structure had been in existence for all periods presented.~~

In March 2018, the Founder and the CEO set up a new limited company, Tianjin Shangde Online Education Technology Co., Ltd. (“Tianjin Shangde”) to operate online education services. Subsequently, in May 2018, Tianjin Studyvip Education Co., Limited (“Tianjin Sunlands"), a wholly-owned subsidiary of the Group, entered into a series of contractual arrangements with Tianjin Shangde, and the shareholders of Tianjin Shangde, through which the Company obtained effective control over, and became the primary beneficiary of, Tianjin Shangde.

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

As of December 31, ~~2018,~~2020, details of the Company’s major subsidiaries, ~~its~~ VIEs and VIEs’ subsidiaries were as follows:

* These entities are controlled by the Company pursuant to the contractual agreements disclosed below.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s financial statements include, but are not limited to, consolidation of VIEs, valuation allowance for deferred tax assets, the variable consideration to be earned for certain online courses and impairment of long-term assets. Actual results could materially differ from those estimates.

The consolidated financial statements include the financial statements of the Company and its subsidiaries, and VIEs and VIEs’ subsidiaries. All intercompany transactions and balances were eliminated upon consolidation.

There are some uncertainties as to whether applicable PRC laws and regulations prohibit foreign investors from providing telecommunications value-added services in the PRC. As a Cayman Islands corporation, the Company is deemed a foreign legal person under PRC laws. Accordingly, ~~Wuhan Zhibo and Tianjin Sunlands,~~ the Company’s wholly owned subsidiaries in the PRC, as foreign invested companies, may be deemed to be a telecommunications value-added services ~~provider~~providers in the PRC. To comply with these foreign ownership restrictions, the Company operates ~~substantially all of~~ its online education services partially through its VIEs ~~Beijing Sunlands and Tianjin Shangde,~~ and their subsidiaries, in the PRC. The Company through its wholly owned subsidiaries ("WFOEs") located in the PRC entered into a series of contractual agreements with the VIEs and their shareholders. Through ~~the~~ below contractual agreements, ~~Wuhan Zhibo~~the Company has (1) the power to direct the activities that most significantly affect the economic performance of the VIEs, and ~~Tianjin Sunlands have (1)~~(2) the right to receive the economic benefit of the VIEs that could potentially be significant to the VIEs. As a result, the shareholders of the VIEs lack the power to direct the activities of the VIEs ~~and their subsidiaries~~ that most significantly ~~affect their~~impact the entity's economic performance, the obligation to absorb the expected losses, and ~~(2)~~ the right to receive ~~substantially all~~ the ~~benefits from~~expected residual returns of the entity. Accordingly, the Company is considered as the primary beneficiary of the VIEs, and ~~their subsidiaries. They are therefore considered~~ the ~~primary beneficiaries~~Company has consolidated the financial results of the VIEs and their subsidiaries ~~and accordingly,~~in its consolidated financial statements.

As of December 31, 2020, the ~~results of operations, assets and liabilities of the~~Group’s VIEs ~~and their subsidiaries~~that are ~~consolidated in the Group's financial statements~~.

~~Agreements that transfer economic benefits~~material to the ~~Company~~Group’s business and operations are Beijing Sunlands and Tianjin Shangde.

~~Risks in relation to VIE structure~~

The ~~Company believes that the contractual arrangements with Beijing Sunlands, Tianjin Shangde and their shareholders~~accompanying notes are ~~in compliance with existing PRC laws and regulations and are legally enforceable. However, the contractual arrangements are subject to risks and uncertainties, including~~:

~~Beijing Sunlands, Tianjin Shangde and their shareholders may have or develop interests that conflict with the Group’s interests, which may lead them to pursue opportunities in violation~~an integral part of the aforementioned contractual agreements. If the Group cannot resolve any conflicts of interest or disputes between the Group and the shareholders of Beijing Sunlands and Tianjin Shangde, the Group would have to rely on legal proceedings, which could result in disruption of its business, and there is substantial uncertainty as to the outcome of any such legal proceedings.

Beijing Sunlands, Tianjin Shangde and their shareholders could fail to obtain the proper operating licenses or fail to comply with other regulatory requirements. As a result, the PRC government could impose fines, new requirements or other penalties on the VIEs or the Group, mandate a change in ownership structure or operations for the VIEs or the Group, restrict the VIEs or the Group’s use of financing sources or otherwise restrict the VIEs or the Group’s ability to conduct business.

The PRC government may declare the aforementioned contractual arrangements invalid. They may modify the relevant regulations, have a different interpretation of such regulations, or otherwise determine that the Group or the VIEs have failed to comply with the legal obligations required to effectuate such contractual arrangements.

If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government may restrict or prohibit the Group’s business and operations in China.

The Group’s ability to conduct its business may be negatively affected if the PRC government were to carry out any of the aforementioned actions. As a result, the Group may not be able to consolidate Beijing Sunlands, Tianjin Shangde and their subsidiaries in the consolidated financial ~~statements as~~statements.

2.	SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation and use of estimates

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s financial statements include, but are not limited to, consolidation of VIEs, valuation allowance for deferred tax assets, the variable consideration to be earned ~~under refundable course model, useful lives of property~~for certain online courses and ~~equipment,~~ impairment of long-term ~~assets and valuation of share-based compensation.~~assets. Actual results could materially differ from those estimates.

Principles of consolidation

~~F-13~~

The VIE arrangements

There are some uncertainties as to whether applicable PRC laws and regulations prohibit foreign investors from providing telecommunications value-added services in the PRC. As a Cayman Islands corporation, the Company is deemed a foreign legal person under PRC laws. Accordingly, the Company’s wholly owned subsidiaries in the PRC, as foreign invested companies, may be deemed to be telecommunications value-added services providers in the PRC. To comply with these foreign ownership restrictions, the Company operates its online education services partially through its VIEs and their subsidiaries, in the PRC. The Company through its wholly owned subsidiaries ("WFOEs") located in the PRC entered into a series of contractual agreements with the VIEs and their shareholders. Through below contractual agreements, the Company has (1) the power to direct the activities that most significantly affect the economic performance of the VIEs, and (2) the right to receive the economic benefit of the VIEs that could potentially be significant to the VIEs. As a result, the shareholders of the VIEs lack the power to direct the activities of the VIEs that most significantly impact the entity's economic performance, the obligation to absorb the expected losses, and the right to receive the expected residual returns of the entity. Accordingly, the Company is considered as the primary beneficiary of the VIEs, and the Company has consolidated the financial results of the VIEs and their subsidiaries in its consolidated financial statements.

As of December 31, 2020, the Group’s VIEs that are material to the Group’s business and operations are Beijing Sunlands and Tianjin Shangde.

Agreements that transfer economic benefits to the Company

Exclusive Technical Consultation and Service Agreement

Without WFOEs’ prior written consent, VIEs and VIEs’ subsidiaries are prohibited from engaging any third party to provide any services contemplated by this agreement. In addition, WFOEs have exclusive and proprietary ownership, rights and interests in any and all intellectual properties arising out of or created during the performance of this agreement. VIEs and VIEs’ subsidiaries agree to pay a quarterly service fee to WFOEs at an aggregate amount of a certain percentage ranging from 10% to 100% of VIEs and VIEs’ subsidiaries’ monthly revenue. Unless terminated by WFOEs, this agreement will remain effective until the dissolution of VIEs and VIEs’ subsidiaries. Without WFOEs’ prior written consent, VIEs and VIEs’ subsidiaries do not have the right to terminate this exclusive technical consultation and service agreement.

2.	SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation and use of estimates

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Principles of consolidation

The VIE arrangements

There are some uncertainties as to whether applicable PRC laws and regulations prohibit foreign investors from providing telecommunications value-added services in the PRC. As a Cayman Islands corporation, the Company is deemed a foreign legal person under PRC laws. Accordingly, the Company’s wholly owned subsidiaries in the PRC, as foreign invested companies, may be deemed to be telecommunications value-added services providers in the PRC. To comply with these foreign ownership restrictions, the Company operates its online education services partially through its VIEs and their subsidiaries, in the PRC. The Company through its wholly owned subsidiaries ("WFOEs") located in the PRC entered into a series of contractual agreements with the VIEs and their shareholders. Through below contractual agreements, the Company has (1) the power to direct the activities that most significantly affect the economic performance of the VIEs, and (2) the right to receive the economic benefit of the VIEs that could potentially be significant to the VIEs. As a result, the shareholders of the VIEs lack the power to direct the activities of the VIEs that most significantly impact the entity's economic performance, the obligation to absorb the expected losses, and the right to receive the expected residual returns of the entity. Accordingly, the Company is considered as the primary beneficiary of the VIEs, and the Company has consolidated the financial results of the VIEs and their subsidiaries in its consolidated financial statements.

As of December 31, 2020, the Group’s VIEs that are material to the Group’s business and operations are Beijing Sunlands and Tianjin Shangde.

Business Operation Agreement

Under the business operation agreement each of VIEs, VIEs' subsidiaries and the shareholders of VIEs confirmed and agreed that, without WFOEs’ prior written consent, it shall not make any transaction that has a material adverse effect on the assets, business, personnel, obligations, rights or operations of VIEs and VIEs' subsidiaries, including but not limited to sale or purchase of any assets or rights exceeding RMB50, incurrence of any encumbrance on any of its assets, including intellectual property rights, in favor of a third party, amendment of its articles of association or business scope, or change of its normal operation procedures. VIEs, VIEs' subsidiaries and the shareholders of VIEs shall accept and execute opinions and instructions of WFOEs in connection with the employee engagement and dismissal, daily operations and financial management systems. The shareholders of VIEs shall elect or appoint the candidates recommended by WFOEs as VIEs’ directors and supervisors, and procure the appointment of VIEs’ chairman of the board and senior management pursuant to WFOEs’ designation. The agreement also provides that if any of the agreements among WFOEs, VIEs and the VIEs' subsidiaries is terminated, WFOEs are entitled to terminate all of the other agreements among themselves, VIEs and VIEs' subsidiaries. This agreement will remain binding until dissolution of VIEs and all the VIEs' subsidiaries.

Powers of Attorney

Pursuant to the powers of attorney executed by the shareholders of VIEs, the shareholders of VIEs each irrevocably authorized WFOEs to act on their respective behalf as exclusive agent and attorney with respect to all rights of shareholders concerning all equity interests held by each of them in VIEs, including but not limited to propose to convene shareholder meetings, accept any notice with respect to the convening and proceeding of the shareholder meeting, attend shareholder meetings, sign the shareholders resolutions on behalf of, exercise all the shareholder’s rights and VIEs’ articles of association (including but not limited to voting rights and the sale, transfer, pledge, or dispose of all equity interests held in part or in whole), and designate and appoint on their respective behalf the president, directors, supervisors, chief executive officer, chief financial officer and other senior management members of VIEs.

Spousal Consent Letters

Pursuant to the spousal consent letters executed by the spouses of the general partners of entities as the shareholders of VIEs, the signing spouse confirmed and agreed that the equity interests of VIEs are the own property of their spouses and shall not constitute the jointly possessed property of the couples. The spouses also irrevocably waived any potential right or interest that may be granted by operation of applicable law in connection with the equity interests of VIEs held by their spouses.

As a result of the contractual arrangements above, WFOEs bear the economic risks and receive the economic benefits of the VIEs and are the primary beneficiary of the VIEs. Therefore, the Company has consolidated the financial results of the VIEs and their subsidiaries in its consolidated financial statements.

Risks in relation to VIE structure

The Company believes that the contractual arrangements with VIEs and their shareholders are in compliance with existing PRC laws and regulations and are legally enforceable. However, the contractual arrangements are subject to risks and uncertainties, including:

•

VIEs and their shareholders may have or develop interests that conflict with the Group’s interests, which may lead them to pursue opportunities in violation of the aforementioned contractual agreements. If the Group cannot resolve any conflicts of interest or disputes between the Group and the shareholders of VIEs, the Group would have to rely on legal proceedings, which could result in disruption of its business, and there is substantial uncertainty as to the outcome of any such legal proceedings.

•

VIEs and their shareholders could fail to obtain the proper operating licenses or fail to comply with other regulatory requirements. As a result, the PRC government could impose fines, new requirements or other penalties on the VIEs or the Group, mandate a change in ownership structure or operations for the VIEs or the Group, restrict the VIEs or the Group’s use of financing sources or otherwise restrict the VIEs or the Group’s ability to conduct business.

•

The Group’s ability to conduct its business may be negatively affected if the PRC government were to carry out any of the aforementioned actions. As a result, the Group may not be able to consolidate VIEs and their subsidiaries in the consolidated financial statements as the Group may lose the ability to exert effective control over VIEs and their shareholders, and the Group may lose the ability to receive economic benefits from VIEs.

NaN creditor (or beneficial interest holders) of the VIEs have recourse to the general credit of the Company or any of its consolidated subsidiaries. No terms in any arrangements, considering both explicit arrangements and implicit variable interests, require the Company or its subsidiaries to provide financial support to the VIEs. However, if the VIEs ever needs financial support, the Company or its subsidiaries may, at its option and subject to statutory limits and restrictions, provide financial support to the VIEs through loans to the shareholders of the VIEs or entrustment loans to the VIEs.

Foreign currency translation and transactions

The Group’s reporting currency is Renminbi (“RMB”). The functional currency of the subsidiaries incorporated outside the mainland China is United States dollar (“US dollar” or “US$”). The functional currency of all the other subsidiaries, the VIEs and VIEs’ subsidiaries is RMB.

Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are remeasured into the applicable functional currencies at historical exchange rates. Revenues and expenses are translated using the average rate of exchange in effect during the reporting period. Translation adjustments are reported and shown as a separate component of other comprehensive loss in the consolidated statements of changes in shareholders’ deficit and the consolidated statements of comprehensive loss.

Transactions in currencies other than the functional currencies during the year are converted into the applicable functional currencies at the applicable rates of exchange prevailing at the dates of the transactions. Transaction gains and losses are recorded in the consolidated statements of operations.

Convenience Translation

The Group’s business is primarily conducted in China and all of the revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into US dollars using the ~~then current~~ exchange ~~rates,~~rate as of balance sheet date, for the convenience of the readers.

Cash and cash equivalents

Cash and cash equivalents comprise cash at banks and on hand and term deposits, which have original maturities of three months or less when purchased and are subject to an insignificant risk of changes in value. The carrying value of cash equivalents approximates market value.

An impairment charge is recorded in the consolidated statements of operations if the carrying amount of an investment exceeds the investment’s fair value. and such excess is determined to be other-than-temporary.

For investment products with variable interest rates and unsecured principal and no restriction on withdrawal, the Group elects the fair value option to record them at fair value in accordance with ASC 825 Financial Instruments. Changes in the fair value are recorded in the consolidated statements of operations.

Long-term investments

Investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest through investment in common shares or in-substance common shares, are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee between 20% and 50%, and other factors, such as representation on the investee’s board of directors, voting rights and the impact of commercial arrangements, are also considered in determining whether the equity method of accounting is appropriate. For certain investments in limited partnerships, where the Group holds less than a 20% equity or voting interest, the Group may also have significant influence.

Under the equity method of accounting, the Group initially records its investment at cost and subsequently recognizes the Group’s proportionate share of each equity investee’s net income or loss after the date of investment into earnings and adjusts the investment carrying amount accordingly.

The Group reviews its equity method investments for impairment whenever an event or circumstance indicates that any other-than-temporary impairment has occurred. The Group considers available quantitative and qualitative evidence in evaluating potential impairment of its equity method investments. An impairment charge is recorded when the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than-temporary.

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The level in the hierarchy within which the fair value measurement in its entirety falls is based upon the lowest level of input that is significant to the fair value measurement as follows:

Level 1

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Financial instruments

The Group’s financial instruments consist primarily of cash and cash equivalents, short-term investments, ~~amounts due from related parties,~~ other current liabilities and long-term debt. The carrying amount of long-term debt approximates fair value as its interest rates are at the same level of current market yield for comparable debts. The carrying amounts of other financial instruments approximate their fair values due to short-term maturities.

Property and equipment, net

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows:

Category		Estimated useful life
Buildings		36-37 years
Leasehold and buildings improvements		Shorter of lease term or expected useful life

Land use right, net

Land use right is recorded at cost less accumulated amortization and amortized on a straight-line basis over the term of the land certificate of 50 years.

Impairment of long-lived assets

The Group reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Group measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group would recognize an impairment loss based on the fair value of the assets. The Group did not record any impairment losses on its long-lived assets during the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018.~~2020.

Revenue recognition

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This standard replaced existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. The ASU also includes guidance regarding the accounting for contract acquisition costs, which includes sales commissions. The Group has early adopted the new standard as of January 1, 2017 using the full retrospective method which requires the Group to present its financial statements for all periods as if Topic 606 had been applied to all prior periods. The Group did not apply practical expedients as provided under Topic 606.

The Group follows five steps for its revenue recognition under ~~Topic~~ASC 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Group’s revenue is reported net of discount, ~~business tax,~~ value added tax and related surcharges. The primary sources of the Group’s revenues are as follows:

Online education services

For online education services, the Group provides an integrated online education service package to students, including online live streaming audio-video interactive course content, recorded previous live audio-video course content, quiz banks, online chat rooms, and educational contents. The services and goods provided in the package are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming and recorded courses which are not distinct and are not sold standalone. Therefore, the ~~Group’s~~Group's integrated online education services package is accounted for as a single performance obligation. The weighted average service period for degree- or diploma-oriented post-secondary courses and professional certification preparation and professional skills courses was 3130 months and 209 months, respectively, for the year ended December 31, ~~2018.~~2020.

The transaction price of the integrated online education service package is determined by the contract amount net of any discounts. Students are offered a full, unconditional refund within 24 hours upon ~~enrollment, and a partial refund for the~~enrollment. Prior to June 2019, undelivered courses was eligible for refund, excluding registration fees, within 7 ~~days.~~days after enrollment. For course contracts entered after June 2019, undelivered courses is eligible for refund during the entire service period, excluding registration fees.

The ~~Group’s~~Group's deferred costs represent the unamortized incremental sales commission relating to obtaining of customers contract, and the contract liability primarily consists of deferred revenue.

Student Financing

The Group offers an installment payment option to students, under which the students obtain loans, from accredited credit sources (“Loan Companies”) for the purpose of satisfying the student’s tuition payment due. The borrowing student is obligated to repay the loan principal in installments over periods ranging from 3 months to 1218 months to the Loan Companies, while the Group agrees with the Loan Companies to bear the student’s interest expense and service fees. The Loan Companies remit the tuition to the Group for students to complete the registration. The interest expense and service fees are recorded as a reduction of the transaction price.

Deferred Revenue

Revenues related to the Group’s online courses are recognized over time. Deferred revenue consists of tuition fees received from students for which services have not yet been provided to students.

~~Business taxes~~

Prior to May 2016, Beijing Sunlands and its subsidiaries were subject to business tax and related surcharges at a rate of 3.36% on revenues related to educational services and 5.6% on non-educational services, respectively. The net revenues are presented net of those taxes incurred.

Value added taxes (“VAT”)

~~Beginning in May 2016,~~The Group's services are subject to VAT at the rate of 6% for general-VAT-payer entities in accordance with ~~Tax~~tax rule, ~~(Cai Shui [2016] No. 68), the non-academic educational programs and services are~~except that certain subsidiaries were subject to a simple VAT collection method at a rate of 3%. Entities which are subject to the tax rate of 3% are not allowed to offset qualified input VAT paid to suppliers against their output VAT liabilities. The Group’s educational services, which were previously subject to business tax, are therefore subject to VAT at the rate of 3%. For Tianjin Shangde, the educational services are subject to VAT at the rate of 6%. For non-educational services, the VAT rate is 6%, before June 2019.

Since January 2020, in accordance with ~~Tax rule (Cai Shui [2016] No. 36).~~Announcement of the Ministry of Finance and the State Taxation Administration [2020] No.8, due to the Novel coronavirus (“COVID-19”) pandemic, the VAT on certain services was temporarily exempted for the year ended December 31, 2020. The VAT exemption is recorded as other income in the consolidated statements of operations in the year ended December 31, 2020.

Cost of revenue

Cost of revenues consist of expenditures incurred in the generation of the Group’s revenue, includes but not limited to salaries and benefits paid to teachers, related rental expenses, server management costs, bandwidth costs, payment processing costs, insurance cost, depreciations for property and equipment and amortizations for intangible assets.

Product development expenses

Product development expenses primarily consist of (i) salaries and benefits for innovation and development of course content, product and technology development personnel, and (ii) office rental, general expenses and depreciation and amortization expenses associated with the product development activities. The Group’s product development activities primarily consist of the development and enhancement of the Group’s educational content, applications and platforms. The Group has expensed all product development expenses when incurred.

The Group leases administrative office spaces and enrollment centers in different cities in the PRC under operating leases. The Group determines whether an arrangement constitutes a lease at inception. The Group has lease agreements with ~~the leasing company~~lease and non-lease components, which are generally accounted for asseparately. The allocation of the consideration between the lease and the non-lease components is based on the relative stand-alone prices of lease components included in the lease contracts. Operating lease right-of-use assets and liabilities are recognized at lease commencement date based on the present value of remaining lease payments over the lease terms. The Group uses the implicit rate when readily determinable, or its incremental borrowing rate based on the information available, at the commencement date in determining the present value of lease payments. Certain leases include renewal options and/or termination options. Renewal options are included in the lease term if the Group is reasonably certain to exercise those options while options to terminate the lease are only included in the lease term if the Group is reasonably certain not to exercise those options. Lease expense is recorded on a straight-line basis over the lease term.

For short-term leases, the Group records operating ~~leases. Payments made under operating leases are charged to the~~lease expense in its consolidated statements of operations on a straight-line basis over the lease term.

Government subsidies

Income taxes

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized. The impact of an uncertain income tax position is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes.

Comprehensive loss

Comprehensive loss includes net loss and foreign currency translation adjustments and is reported in the consolidated statements of comprehensive loss. The Group presents the components of net loss, the components of other comprehensive loss and total comprehensive loss in two separate but consecutive statements.

Net loss per share

Prior to IPO, basic net loss per share is computed by dividing net loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding during the year using the two-class method.

The holders of the convertible redeemable preferred shares are entitled to share dividends on a pro rata basis, as if their shares had been converted into ordinary shares. Accordingly, the Company has used the two-class method in computing net loss per share. Under the two-class method, net loss is allocated on a pro rata basis to each class of ordinary shares and other participating securities based on their participating rights.

~~After IPO, basic~~Basic net loss per share is computed by dividing net loss attributable to ordinary shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted net loss per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised into common shares. To calculate the number of shares for diluted loss per share, the effect of the share options is computed using the treasury stock method.

As the Company was loss making for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, the effect of potential issuances of shares for the ~~convertible redeemable preferred shares and~~ share options would be anti-dilutive, and therefore basic and diluted losses per share are the same in those periods.

Share-based compensation

Share-based compensation awards which require the issuance of a variable number of shares to settle a fixed monetary amount are recorded as liabilities.

Significant risks and uncertainties

Foreign currency risk

RMB is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into foreign currencies. The value of RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. The cash and cash equivalents of the Group included aggregate amounts of ~~RMB104,244~~RMB259,612 and ~~RMB157,103,~~RMB131,810, which were denominated in RMB at December 31, ~~2017~~2019 and ~~2018,~~2020, representing ~~18.6%~~18.5% and ~~12.6%~~17.3% of the cash and cash equivalents at December 31, ~~2017~~2019 and ~~2018,~~2020, respectively.

Concentration of credit risk

Financial instrument that potentially expose the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, short-term investments ~~amounts due~~and receivables from ~~related parties and prepaid expenses and other current assets.~~third party payment agencies. The Group places its cash and cash equivalents and short-term investments in financial institutions with high credit ratings.

There are no revenues from customers which individually represent greater than 10% of the total net revenues for any year of the three years period ended December 31, ~~2018.~~2020.

~~Newly adopted accounting pronouncements~~

In January 2016, the FASB issued a new pronouncement ASU 2016-01 Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.

~~Recent accounting pronouncements not yet adopted~~

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance supersedes existing guidance on accounting for leases with the main difference being that operating leases are to be recorded in the statement of financial position as right-of-use assets and lease liabilities, initially measured at the present value of the lease payments. For operating leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and liabilities. For public business entities, the guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the guidance is permitted. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases. The amendments in this ASU are of a similar nature to the items typically addressed in the Codification improvements project. However, the Board decided to issue a separate ASU for the improvements related to Accounting Standards Update No. 2016-02, Leases (Topic 842), to increase stakeholders’ awareness of the amendments and to expedite the improvements. The amendments in this ASU affect narrow aspects of the guidance issued in ASU 2016-02. For entities that have early adopted Topic 842, the amendments in this Update should be effective upon issuance of the final Update and the transition requirements should be the same as those in Topic 842. For entities that have not adopted Topic 842, the effective date and transition requirements of the amendments should be the same as the effective date and transition requirements in Topic 842.

In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements. The amendments in this ASU related to separating components of a contract affect the amendments in ASU 2016-02, which are not yet effective but can be early adopted. For entities that have not adopted Topic 842 before the issuance of this ASU, the effective date and transition requirements for the amendments in this ASU related to separating components of a contract are the same as the effective date and transition requirements in ASU 2016-02. All entities, including early adopters that elect the practical expedient related to separating components of a contract in this ASU must apply the expedient, by class of underlying asset, to all existing lease transactions that qualify for the expedient at the date elected. Specifically, under the amendments in ASU 2018-11, (1) entities may elect not to recast the comparative periods presented when transitioning to ASC 842 and (2) lessors may elect not to separate lease and nonlease components when certain conditions are met. Before ASU 2018-11 was issued, transition to the new lease standard required application of the new guidance at the beginning of the earliest comparative period presented in the financial statements. The Group has substantially completed its evaluation of the effect of the adoption of this ASU and expects the adoption will result in an increase in the assets and liabilities on the consolidated balance sheet for the operating leases and will have insignificant impact on its consolidated statements of operations and cash flows. Adoption of the standard will result in recognition of additional right-of-use assets and lease liabilities by an amount approximated to the further minimum lease commitments disclosed in Note 20 on a discounted basis as of January 1, 2019, respectively.

The Group measures long-term investments at fair value on a nonrecurring basis whenever events or changes in circumstances indicate that the carrying value may no longer be recoverable.

~~(Amounts in thousands, except~~ Refer to Note 9 for ~~share and per share data, or otherwise noted)~~

In October 2017, the shareholders of the Company approved the 2017 Share Incentive Plan (the “2017 ESOP”) under which the Company can grant a maximum of 483,846 ordinary shares. On August 24, 2018, the Company further approved an additional 345,503 ordinary shares for issuance, and therefore, 829,349 ordinary shares reserved for issuance under the 2017 ESOP.

NaN options were granted during the ~~Company granted 363,452 options under the 2017 ESOP for an exercise price of $0.0047 (equivalent to RMB0.0312).~~

~~The options shall vest and become exercisable immediately at the grant date.~~

~~Any unexercised option shall be immediately forfeited upon the date of the Company’s IPO.~~

~~The entire 363,452 options granted under this scheme were exercised at the grant date and a compensation expense of RMB 205,630 was recorded for the year~~years ended December 31, ~~2017.~~

~~On October 20, 2017, the Company granted 66,053 options under the 2017 ESOP for an exercise price of $84.75 (equivalent to RMB560.95).~~

~~The options shall vest~~2018, 2019 and ~~become exercisable in the installments of 10%, 20%, 30% and 40%, respectively on the first, second, third and fourth anniversary of the date of the Company’s IPO.~~

~~Any unexercised option shall be immediately forfeited upon the tenth anniversary of October 20, 2017.~~

The vesting and exercisability of options granted under Scheme II of the 2017 ESOP are both upon the IPO which is not assessed as probable until the effective date of the IPO. Therefore, no share-based compensation expenses were accrued for the year ended December 31, 2017. Upon the completion of the Company's IPO in March 2018, a compensation expense of RMB2,751 was recorded for the year ended December 31, 2018.

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

2020. A summary of option activities ~~and changes~~ during the year ended December 31, ~~2018~~2020 were presented below:

The Company calculated the estimated fair value of the options on the respective grant dates using the binomial option pricing model with the assistance from an independent valuation firm, with the following assumptions used.Non-vested Shares

Risk-free interest rate was estimated based on the yield to maturity of US Sovereign Strips Curve with maturity date closest to the life to expiration, plus country default spread of China as of the valuation dates.

~~The volatility factor estimated was based on the daily share price volatility of comparable companies for an observation period that matches the life to expiration of share options.~~

~~The management does not have any dividend policy after IPO. Hence, the dividend payout ratio is assumed to be 0%.~~

~~Exercise multiple is based on empirical research on typical employee stock option exercising behavior.~~

~~In addition to the Share Incentive Plans~~ ~~disclosed~~ above, in August 2017, the Company issued 146,930 ordinary shares to certain directors and management at no consideration as a share-based compensation. As a result, a compensation expense of RMB83,133 was recorded for the year ended December 31, 2017.

On May 17, 2018, the ~~Company's~~Company’s Board of Directors approved to award certain independent directors for their services rendered for the year ended December 31, 2018. The awards ~~would be~~ were settled by issuing a variable number of the ~~Company’s~~Company's shares valued at RMB1,100 and the share number is determined by dividing ~~such fixed amount~~RMB1,100 by the average closing price during certain periods of time. The Group accounted for the awards to the independent directors as share-based compensationclassified as liabilities for the year ended December 31, 2018.

On August 1, 2020, the Company granted 80,000 nonvested shares to 2 employees which were vested immediately and a compensation expense of RMB 27,898 was ~~included in accrued expenses and other current liabilities.~~recorded for the year ended December 31, 2020.

Total share-based compensation expense of share-based awards granted to employees, certain directors and management recognized for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018~~2020 were as follows:

As of December 31, ~~2018,~~2020, the unrecognized share-based compensation expenses related to share options were ~~RMB14,083,~~RMB3,264, which are expected to be recognized over a weighted average period of ~~3.2~~1.2 years.

The Group's leases consist of operating leases for administrative office spaces and enrollment centers in different cities in the PRC. For leases with terms greater than 12 months, the Group records the related asset and lease liability at the present value of lease payments over the term. As of December 31, 2020, the Group did not have additional operating leases that have not yet commenced. As of December 31, 2020, the Group had no long-term leases that were classified as a financing lease. Short-term lease cost for the year ended December 31, 2020 was immaterial.

For the years ended December 31, 2019 and 2020, 0 variable lease cost was recognized in the consolidated financial statements of the Group.

The following is a maturity analysis of the annual undiscounted cash flows for lease liabilities as of December 31, 2020:

Payments under operating leases are expensed on the straight-line basis over the periods of their respective leases. The terms of the leases do not contain rent escalation or contingent rents. For the years ended December 31, 2018, 2019 and 2020, the total rental expenses for all operating leases amounted to RMB107,331, RMB96,165 and RMB91,814, respectively, recorded in cost of revenues, selling expenses, research and development expenses and general and administrative expenses on the consolidated statements of operations.

Under current law of Cayman Islands, the Company is not subject to income or capital gains taxes. In addition, dividends payments are not subject to tax withholding in the Cayman Islands.

The Company’s subsidiary, Sunlands HK is located in Hong Kong and is subject to a two-tiered income tax rate for taxable income earned in Hong Kong with effect from April 1, 2018. The first HK$2 million of profits earned by Sunlands HK will be taxed at 8.25%, while the remaining profits will continue to be taxed at the existing 16.5% tax rate. NoNaN provision for Hong Kong profits tax has been made in the consolidated financial statements as it has no assessable income for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018.~~2020.

The Group’s subsidiaries, VIEs and VIEs’ subsidiaries incorporated in the PRC were generally subject to a corporate income tax rate of 25%.

The Enterprise Income Tax Law (the “EIT Law”) of the PRC, effective since January 1, 2008, applies a uniform 25% enterprise income tax rate to all resident enterprises in China, including foreign invested enterprises.

~~From 2015, Previous WFOE~~Beijing Sunlands was qualified as “high and new technology enterprise strongly supported by the State” (“HNTE”) ~~under the EIT Law,~~ and ~~therefore,~~ was accordingly entitled to a preferential ~~income~~ tax rate of 15% from ~~2015~~calendar years 2016 through ~~2017.~~

~~In 2016, Beijing Sunlands obtained HNTE qualification~~2021 and ~~was entitled~~is expected to ~~preferential income tax~~be subject to an EIT rate of 15% ~~from 2016 through 2018.~~

~~The deferred income tax expenses in the consolidated statements of operations were nil, nil and nil for the three years ended December 31, 2018.~~

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

The reconciliation of the effective tax rate and the statutory income tax rate applicable to PRC operations iswas as follows:

If the tax holidays granted to Beijing Sunlands ~~and Previous WFOE~~ were not available, the Group’s income tax expenses would have been nil, which would have no impact on the basic and diluted net loss per ordinary share attributable to the Company, for the three years ended December 31, ~~2018.~~ 2020.

Deferred taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of deferred taxes are as follows:

As of December 31, ~~2018,~~2020, the Company’ subsidiaries, VIEs and VIEs’ subsidiaries registered in the PRC have total net operating loss carry forwards of ~~RMB1,677,243,~~RMB3,305,732, which would expire on various dates through December 31, ~~2019~~2022 to December 31, ~~2028.~~2030.

The authoritative guidance requires that the Group recognizes the impact of a tax position in the financial statements if that position is more likely than not of being sustained upon audit by the tax authority, based on the technical merits of the position. Under PRC laws and regulations, arrangements and transactions among related parties may be subject to examination by the PRC tax authorities. If the PRC tax authorities determine that the contractual arrangements among related companies do not represent a price under normal commercial terms, they may make adjustments to the companies’ income and expenses. A transfer pricing adjustment could result in additional tax liabilities. The Group did ~~not~~0t have any significant unrecognized uncertain tax positions as of and for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018.~~2020.

In addition, uncertainties exist with respect to how the current income tax law in the PRC applies to the Group’s overall operations, and more specifically, with regard to tax residency status. The New EIT Law includes a provision specifying that legal entities organized outside of the PRC will be considered residents for Chinese income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the New EIT Law provide that non-resident legal entities will be considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting and properties, occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Group does not believe that the legal entities organized outside of the PRC within the Group should be treated as residents for EIT law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC should be deemed resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income taxes, at a rate of 25%.

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

For the purpose of calculating net loss per share as a result of the 2017 Reorganization as described in Note 1, the number of ordinary shares used in the calculation reflects the outstanding ordinary shares of the Company in 2017 as if the Group’s 2017 Reorganization took place on January 1, 2016:

Given the Company's loss making position for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, the effect of potential issuances of shares for ~~the convertible redeemable preferred shares and~~ share options would be anti-dilutive:

~~In October 2017, the Group disposed a subsidiary to Shangde Jiaxun with a total consideration of RMB1,000 and a gain of RMB178 was recorded~~(3)39,225 share options were not considered in the ~~Group’s consolidated statement~~computation of ~~operations~~diluted net loss per share for the year ended December 31, ~~2017.~~2020.

~~Future minimum payments under non-cancelable operating leases related to offices and public displays with initial terms of one-year or longer consisted of the following at December 31, 2018:~~

Payments under operating leases are expensed on the straight-line basis over the periods of their respective leases. For the years ended December 31, 2016, 2017 and 2018, the total rental expenses for all operating leases amounted to RMB53,714, RMB65,214 and RMB107,331, respectively.

The Group was obligated to pay ~~RMB25,000~~RMB9,840 for the long-term investments as of December 31, ~~2018.~~2020.

From time to time, the Group is subject to legal proceedings and claims incidental to the conduct of its business. The Group accrues the liability when the loss is probable and reasonably estimable.

In June 2019, the Company, and certain of its current and former directors and officers and its underwriters in the initial public offering were named as defendants in a securities class action filed in the U.S. District Court for the Eastern District of New York. Amended complaints in this class action were filed in November 2019. The action, purportedly brought on behalf of a class of persons who allegedly suffered damages as a result of their trading in the ADSs, alleges that the Company's registration statement on Form F-1 in connection with the March 2018 initial public offering contains material misstatements and omissions in violation of the U.S. federal securities laws. The Company filed a motion to dismiss the action in March 2020, which was denied by an order dated March 31, 2021. The Company believes that the allegations are without merit and intends to defend itself vigorously against those claims. It is not possible at this time to reasonably estimate possible losses, or even a range of reasonably possible losses, in connection with the litigation.

The Group’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer of the Group, who reviews financial information of operating segments when making decisions about allocating resources and assessing performance of the Group. An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, and is identified on the basis of the internal financial reports that are provided to and regularly reviewed by the Group’s CODM.

For the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, the Group’s CODM reviewed the financial information of the education business carried out by the Group on a consolidated basis. The Group has ~~one~~1 operating segment, which is the provision of online education service. The Group operates solely in the PRC and all of the Group’s long-lived assets are located in the PRC.

~~(Amounts in thousands, except for share and per share data, or otherwise noted)~~

Full time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the PRC subsidiaries of the Group make contributions to the government for these benefits based on certain percentages of the employees’ salaries. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts for such employee benefits, which were expensed as incurred, were ~~RMB64,189, RMB164,775~~RMB228,376, RMB182,132 and ~~RMB228,376,~~RMB111,677, for the years ended December 31, ~~2016, 2017~~2018, 2019 and ~~2018,~~2020, respectively.

Relevant PRC statutory laws and regulations permit payments of dividends by the Group’s PRC subsidiaries only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of the Company’s subsidiaries.

In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of association, a foreign invested enterprise established in the PRC is required to provide certain statutory reserves, namely general reserve fund, the enterprise expansion fund and staff welfare and bonus fund which are appropriated from net profit as reported in the enterprise’s PRC statutory accounts, which is included in retained earnings accounts in equity section of the consolidated balance sheets. A wholly-owned foreign invested enterprise is required to allocate at least 10% of its annual after-tax profit to the general reserve until such reserve reaches 50% of its respective registered capital based on the enterprise’s PRC statutory accounts. Appropriations to the enterprise expansion fund and staff welfare and bonus fund are at the discretion of the board of directors for all foreign invested enterprises. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. If any PRC subsidiary incur debt on its own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to the Group. Any limitation on the ability of the PRC subsidiaries to distribute dividends or other payments to their respective shareholders could materially and adversely limit the ability to grow, make investments or acquisitions that could be beneficial to pay dividends.

Additionally, in accordance with the Company Law of the PRC, a domestic enterprise is required to provide statutory common reserve at least 10% of its annual after-tax profit until such reserve reaches 50% of its respective registered capital based on the enterprise’s PRC statutory accounts. The Group’s provision for the statutory common reserve is in compliance with the aforementioned requirement of the Company Law. A domestic enterprise is also required to provide for discretionary surplus reserve, at the discretion of the board of directors, from the profits determined in accordance with the enterprise’s PRC statutory accounts. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends.

Because the Group’s entities in the PRC can only be paid out of distributable profits reported in accordance with PRC accounting standards, the Group’s entities in the PRC are restricted from transferring a portion of their net assets to the Company. The restricted amounts include the paid-in capital and statutory reserves of the Group’s entities in the PRC. The aggregate amount of paid-in capital and statutory reserves, which is the amount of net assets of the Group’s entities in the PRC (mainland) not available for distribution, were ~~RMB1,986~~RMB1,535,678 as of December 31, ~~2018.~~2020.

~~STATEMENT~~STATEMENTS OF ~~CHANGES IN SHAREHOLDERS’ DEFICIT~~COMPREHENSIVE LOSS

~~Note: The number of ordinary shares reflects the outstanding ordinary shares of the Company as if the Group’s 2017 reorganization took place on January 1, 2016.~~F-34

The condensed financial information of Sunlands Technology Group has been prepared using the same accounting policies as set out in the accompanying consolidated financial statements except that the equity method has been used to account for investments in its subsidiaries.

The Company, its subsidiaries, the VIEs and the VIEs’ subsidiaries were included in the consolidated financial statements where the inter-company balances and transactions were eliminated upon consolidation. For purpose of the Company’s stand-alone financial statements, its investments in subsidiaries, the VIEs and the VIEs’ subsidiaries were reported using the equity method of accounting. The Company’s share of loss from its subsidiaries, the VIEs and the VIEs’ subsidiaries were reported as equity in earnings of its subsidiaries, the VIEs and the VIEs’ subsidiaries in the condensed statements of operations.

The Group’s business is primarily conducted in China and all of the revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into US dollars using the exchange rate as of balance sheet date, for the convenience of the readers. Translations of balances in the balance sheet, and the related statement of operations and cash flows from Renminbi (“RMB”) into US dollars as of and for the year ended December 31, 2020 are solely for the convenience of the readers and were calculated at the rate of US$1.00=RMB6.5250, representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on December 31, 2020. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2020, or at any other rate.
