The non-controlling shareholders are nominee shareholders mainly consisting of local residents to comply with local regulations of the Philippines. a History of the Group and Basis of Presentation for the Reorganization The Group began operations in July 2011 through Beijing Dasheng Zhixing Technology Co., Ltd. (‘‘Dasheng Zhixing’’). The beneficial interest of Dasheng Zhixing was held by Mr. Jiajia Huang and Ms. Ting Shu (the ‘‘Founding Shareholders’’) and an angel investor in 2011. On January 5, 2012, another angel investor invested into Dasheng Zhixing. In accordance with the investment agreement, the Founding Shareholders set aside from their own holdings 15% of the ownership of Dasheng Zhixing for an employee option plan. While the plan to establish employee option plan was cancelled, the 15% ownership interest in Dasheng Zhixing was not returned to the Founding Shareholders. Consequently, beneficial interest of Dasheng Zhixing was then 71% by the Founding Shareholders and 29% held by angel investors. 1 Operations and Reorganization (Continued) Given the cost advantage and high English proficiency of teachers in the Philippines, the Group retains teachers in the Philippines. To do this, in August 2012, the Founding Shareholders established, a company in the Philippines, 51Talk English Philippines Corporation (the ‘‘Philippines Co I’’), using funds provided by Dasheng Zhixing. On September 3, 2012, Dasheng Zhixing entered into a service agreement with Philippines Co I, to formalize the business arrangements. Under the agreement, Philippines Co I provides teaching service for the Group in accordance with the Group’s instructions. In return, Dasheng Zhixing pays for all the expenses incurred for the services provided by Philippines Co I. The equity of Philippines Co I is considered to be insufficient to finance its activities without additional subordinated financial support provided by another party. As a result, Dasheng Zhixing is considered to be the primary beneficiary of Philippines Co I as it has the power to direct the activities of Philippines Co I that most significantly impact Philippines Co I’s economic performance and has obligation to absorb losses of Philippines Co I. As such, Dasheng Zhixing consolidates Philippines Co I. Dasheng Zhixing was the predecessor of the Group and operated substantially all of the businesses of the Group prior to November 2012. In order to facilitate international financing, the Group underwent a reorganization (the ‘‘Reorganization’’) from November 2012 until October 2014. In November 2012, the Founding Shareholders incorporated the Company under the Laws of the Cayman Islands to be an offshore holding company for the Group. In June 2013, the Company issued ordinary shares to the two angel investors, in exchange for their equity beneficial ownerships in Dasheng Zhixing. Following the exchange, the ownership of the Company was held 71% by the Founding Shareholders and 29% by the angel investors. In April 2013, China Online Education (HK) Limited (the ‘‘COE HK Co I’’) was incorporated in Hong Kong as a wholly owned subsidiary of the Company. Beijing Dasheng Online Technology Co. Ltd., (‘‘Dasheng Online’’), was set up in June 2013 as a wholly owned subsidiary of COE HK Co I in the PRC. Due to PRC legal restrictions on foreign ownership and investment in the companies in value-added telecommunications market, the Group continues to operate its online education platform through Dasheng Zhixing, Shenzhen Zhixing and Dasheng Zhiyun. To comply with PRC laws and regulations, the Group operate www.51talk.com On June 18, 2013, as part of the restructuring, a series of contractual agreements discussed in 1.b. below were entered into among Dasheng Online, Dasheng Zhixing and shareholders of Dasheng Zhixing. As a result of the agreements, Dasheng Online has the ability to direct substantially all the activities of Dasheng Zhixing, and absorb substantially all of the risks and rewards of the Dasheng Zhixing. Dasheng Online became the primary beneficiary of Dasheng Zhixing and consolidates the financial results of Dasheng Zhixing. The restructuring provided the beneficial interest holders of Dasheng Zhixing received an interest in the Company equal to their beneficial interest in Dasheng Zhixing. On June 3, 2019, a shareholder of Dasheng Zhixing transferred her shares to Mr. Jiajia Huang. The above contractual agreements were updated to reflect the shares transfer, without substantial change of the terms. On August 5, 2021, after involve a new shareholder, Mr. Caijian Jia, who is an employee of the Group, the above contractual agreements were further updated to reflect the capital increase, without substantial change of the terms, equity interest of Dasheng Zhixing was then 72.2750% by Mr. Jiajia Huang, 25.7250% held by Ms. Ting Shu and 2.0000% by Mr. Caijian Jia. On July 21 2014, a series of contractual agreements discussed in 1.b. below were entered into among COE HK Co I, Philippines Co I and the shareholders of Philippines Co I. Pursuant to these agreements COE HK Co I has the ability to direct substantially all the activities of Philippines Co I, and absorb substantially all of the risks and rewards of Philippines Co I. COE HK Co I replaced Dasheng Zhixing as the primary beneficiary of Philippines Co I, and the Group continued to consolidate the financial results of Philippines Co I. 1 Operations and Reorganization (Continued) To further optimize the organizational structure of the Group, in October 2014, 51 Talk English International Limited (the ‘‘COE HK Co II’’) was incorporated with limited liability in Hong Kong as a wholly owned subsidiary of COE HK Co I. China Online Innovations Inc. (the ‘‘Philippines Co II’’), which was incorporated by the Company with limited liability in the Philippines to eventually replace Philippines Co I. The Company owns 99.999993% of the equity interest of Philippines Co II. In order to comply with local laws, there are seven individual shareholders holding an aggregate of 0.000007% of the equity interest of Philippines Co II. A series of contractual arrangements was entered into among the Company, Philippines Co II and the seven individual shareholders. Under these contractual arrangements, the Company has an exclusive option to purchase all of the equity interests in Philippines Co II held by the seven individuals and to exercise their rights as shareholders of Philippines Co II. Since then, Philippine home-based teachers delivering paid lessons on the Company’s platform no longer entered into service agreements with Philippines Co I, but rather entered into service agreements with COE HK Co II. Furthermore, the bulk of the business operations in Philippines Co I was transferred to Philippines Co II, and the Group began to enter into employment agreements with office-based teachers and other full-time employees in the Philippines through Philippines Co II. To further optimize group structure, on January 14, 2016, On Demand English Innovations Inc. (the “Philippines Co III”) was incorporated by the Company with limited liability in the Philippines to replace Philippines Co I. The Company owns 99.999% of the equity interest of Philippines Co III. In order to comply with local laws, there are five individual shareholders holding an aggregate of 0.001% of the equity interest of Philippines Co III. A series of contractual arrangements was entered into among the Company, Philippines Co III and the five individual shareholders. Under these contractual arrangements, the Company has an exclusive option to purchase all of the equity interests in Philippines Co III held by the five individuals and the power to exercise their rights as shareholders of Philippines Co III. In April 2016, all business operations and assets of Philippines Co I were transferred to Philippines Co III, including the office leasehold and office equipment in Baguio City, Philippines. Philippines Co III also entered into new employment agreement with the free trial teachers and support staff previously employed by Philippines Co I. The above series of transactions to reorganize the Group 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. On December 30, 2016, Dasheng Zhixing established a wholly-owned subsidiary, Shanghai Zhishi Education Training Co., Ltd.(“Zhishi Training”), of which the current registered business scope includes “education training: classic English (level 1-9)” .

Refer to Note 1 (d) – liquidity and going concern. 1 Operations and Reorganization (Continued) Under the contractual arrangements with the VIEs, the Company has the power to direct activities of the VIEs through Dasheng Online, COE HK Co I, HAWO Online, Beijing Xiangyue, and can have assets transferred freely out of the VIEs without restrictions. Therefore, the Company considers that there is no asset of the VIEs that can only be used to settle obligations of the respective VIEs, except for registered capital of Dasheng Zhixing amounting to RMB1,143 and RMB1,166 as of December 31, 2020 and 2021, respectively. Since the VIEs are incorporated as limited liability companies under the PRC and Philippine Company Law, creditors of the VIEs do not have recourse to the general credit of the Company. There is currently no contractual arrangement that would require the Company to provide additional financial support to the VIEs. The Group believes that the contractual arrangements among Dasheng Online, COE HK Co I and HAWO Online, Beijing Xiangyue, the VIEs and their shareholders are in compliance with PRC and Philippine laws and regulations, as applicable, and are legally binding and enforceable. However, uncertainties in the PRC and Philippine legal system could limit the Company’s ability to enforce these contractual arrangements. On March 15, 2019, the National People’s Congress promulgated the Foreign Investment Law, which took effect on January 1, 2020. Since it is relatively new, substantial uncertainties exist in relation to its interpretation and implementation. The Foreign Investment Law does not explicitly classify whether variable interest entity that are controlled through contractual arrangements would be deemed as foreign invested enterprises if they are ultimately “controlled” by foreign investors. However, it has a catch-all provision under definition of “foreign investment” that includes investments made by foreign investors in China through other means as provided by laws, administrative regulations or other methods prescribed by the State Council. Therefore, it still leaves leeway for future laws, administrative regulations or provisions of the State Council to provide for contractual arrangements as a form of foreign investment, at which time it will be uncertain whether the Group’s contractual arrangements will be deemed to be in violation of the market access requirements for foreign investment in the PRC and if yes, how the Group’s contractual arrangements should be dealt with. The Foreign Investment Law grants national treatment to foreign-invested entities, except for those foreign-invested entities that operate in industries specified as either “restricted” or “prohibited” from foreign investment in the Special Administrative Measures for Access of Foreign Investment (Negative List) (2021 Version), or the 2021 Negative List, which was jointly promulgated by the Ministry of Commerce of the People’s Republic of China (“MOFCOM”) and the National Development and Reform Commission (“NDRC”) on December 27, 2021 and became effective on January 1, 2022. The Foreign Investment Law provides that foreign-invested entities operating in “restricted” or “prohibited” industries are required to obtain market entry clearance and other approvals from relevant PRC government authorities. If the Group’s control over the PRC consolidated VIEs through contractual arrangements are deemed as foreign investment in the future, and any business of the PRC consolidated VIEs is “restricted” or “prohibited” from foreign investment under the “negative list” effective at the time, the Group may be deemed to be in violation of the Foreign Investment Law, the contractual arrangements that allow us to have control over the PRC consolidated VIEs may be deemed as invalid and illegal, and the Group may be required to unwind such contractual arrangements and/or restructure the Group’s business operations, any of which may have a material adverse effect on the Group’s business operation. The Company’s ability to control the VIEs also depends on the Power of Attorney. The consolidated VIEs have to vote on all matters requiring shareholder approval in the VIEs. As noted above, the Company believes these Power of Attorney are legally enforceable but may not be as effective as direct equity ownership. In addition, if the Group’s corporate structure or the contractual arrangements with the VIEs were found to be in violation of any existing PRC or Philippine laws and regulations, the PRC or the Philippine regulatory authorities could, within their respective jurisdictions: ● ● ● ● 1 Operations and Reorganization (Continued) ● ● ● The imposition of any of these restrictions or actions may result in a material adverse effect on the Group’s ability to conduct its business. In addition, if the imposition of any of these restrictions causes the Group to lose the right to direct the activities of the VIEs or the right to receive their economic benefits, the Group would no longer be able to consolidate the financial statements of the VIEs. In the opinion of management, the likelihood of losing the benefits in respect of the Group’s current ownership structure or the contractual arrangements with the VIEs is remote. As of December 31, 2020 and 2021, the aggregate accumulated deficit of the VIEs was approximately RMB723,925 and RMB515,435 respectively, which have been included in the Group’s accompanying consolidated financial statements. d Liquidity and going concern The Group’s consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities during the normal course of operations. The Group incurred net losses of RMB104,420 for the year ended December 31, 2019, earned net income of RMB146,962 and RMB120,574 for the years ended December 31, 2020 and 2021, respectively. Accumulated deficits were RMB2,051,940 and RMB1,931,366 as of December 31, 2020 and 2021, respectively. The net current liabilities were RMB1,400,431 and RMB929,524 as of December 31, 2020 and 2021, respectively. The operating cash inflows were RMB 397,933 and RMB719,243 for the years ended December 31, 2019 and 2020 and the operating cash outflows were RMB676,063 for the year ended December 31, 2021. The Company assesses its liquidity by its ability to generate cash from operating activities to fund its operations, attract investors and borrow funds on favorable economic terms. On July 24, 2021, the Opinions on Further Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education (the “Alleviating Burden Opinion “or the “Opinion”) was issued by the General Office of the CPC Central Committee and the General Office of the State Council. The Opinion contains high-level policy directives about requirements and restrictions related to online and offline after-school tutoring services, including, among others, banning foreign teachers located overseas from providing tutoring services in the mainland of China. As a result, the Company has stopped selling online tutoring services taught by foreign teachers located overseas to new K-12 students in the mainland of China except for the foregoing, to comply with the Alleviating Burden Opinion. The Company’s continuous operation depends on (i) the level of subsequent refunds to paying students, (ii) whether the Company is allowed to continuously deliver the online tutoring services taught by foreign teachers located overseas to K-12 students in the mainland of China sold before the issuance of the Opinion; (iii) whether the Company may become subject to fines or other penalties by regulators, and (iv) the success of the Company’s business plans as mentioned above. All these factors are subject to inherent uncertainties. The Company’s accumulated deficits and net current liabilities as of December 31, 2021 and the operating cash outflow for the year then ended, and the Company’s business, financial condition, results of operations, and prospects have been and will be materially and adversely affected by the Opinion. These conditions cast substantial doubt about the Company’s ability to continue as a going concern. The Company has taken the following actions and plans to mitigate the significant decline in lessons sold: (i) The Company developed and released all-round proficiency course offering taught by Chinese teachers for K-12 students in the mainland of China. The Company believe the all-round proficiency course offering is in compliance with the Alleviating Burden Opinion and is allowed to operate under the current VIE structure. (ii) The Company offered one-on-one course taught by foreign teachers to students in overseas markets and plans to expand the international business. (iii) The Company has streamlined its operation to reduce operating expenses and plans to continue containing expenses and improving operating efficiency. (iv) The Company has made effort to reduce advances related to prohibited services by providing refunds, exchanges, or replacing such services with alternative compliant services such as the all-round proficiency course offering and plans to continue to do such business activities subsequently. As of December 31, 2021, advances related to non-compliant services have decreased to RMB 1,126,984 . (v) As of December 31, 2021, the Group's balance of cash and cash equivalents, time deposits (current and non-current) and short-term investments was RMB 942,007 , and the Group had no outstanding borrowing under credit agreements. (vi) The Company is exploring strategic options of divesting part of the business and looking for potential investors for capital injection. However, it is uncertain any option will be available to the Company on commercially acceptab |
