Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Principal Activities	1. Organization and Principal Activities (a) Principal activities Lixiang Education Holding Co., Ltd. (formerly known as Lianwai Education Group Limited, the “Company”) was incorporated on September 6, 2018 under the law of the Cayman Islands as an exempted company with limited liability. The Company’s original name was Lianwai Education Group Limited. The Company changed its name to Lixiang Education Holding Co., Ltd. on May 26, 2020. The Company, through its subsidiaries and consolidated variable interest entities (“VIEs”) (collectively referred to as the “Group”) is primarily engaged in providing education services through Zhejiang Lishui Mengxiang Education Development Company Limited and Liandu Foreign Language School in the People’s Republic of China (the “PRC”). On November 28, 2018, the Group disposed Liandu Foreign Language School Kindergarten which provided kindergarten care services. After completing the divestiture, the Company’s remaining principal business is the primary and middle school education business from grade 1 to grade 9. The divestiture was undertaken because private kindergartens are not allowed to be listed independently or to be included as part of a group to be listed pursuant to Article 24 of the Pre-School Significant equity transactions Initial public offering (“IPO”) On October 1, 2020, the Company completed its IPO on the NASDAQ Global Market of 3,333,400 5 9.25 30.8 170.7 26.2 As of December 31, 2019 and 2020, the Company’s major subsidiaries and VIEs are as follows: Name of subsidiaries and VIE Date of establishment Place of incorporation Percentage of direct or indirect economic ownership Principal activities Wholly owned subsidiaries of the Company: Lianwai Investment Co., Ltd. (“Lianwai investment”) Established on September 11, BVI 100 % Investment holding Hong Kong Mengxiang Education Development Group Limited (“HK Mengxiang”) Established on September 20, Hong Kong 100 % Investment holding Zhejiang Mengxiang Consulting Services Co., Ltd.

To facilitate offshore financing, an offshore corporate structure was formed in 2018, which was carried out as follows: 1) On September 6, 2018 2) On September 11, 2018, Lianwai investment was incorporated in British Virgin Islands with 100% ownership by the Company. 3) On September 20, 2018, Mengxiang HK was incorporated in Hong Kong with 100% ownership by Lianwai investment. 4) On October 10, 2018, Liandu WFOE was incorporated in the PRC with 100% ownership by HK Mengxiang. 5) On August 13, 2020, Lishui Xianke was incorporated in the PRC with 100% ownership by Liandu WFOE. In order to comply with the PRC laws and regulations which prohibit or restrict foreign investments into companies involved in restricted businesses, the Group provides education services in the PRC through certain PRC domestic companies, whose equity interests are held by certain management members of the Company or onshore nominees of certain investors of the Company (“Nominee Shareholders”). The Company obtained control over these PRC domestic companies by entering into a series of Contractual Arrangements in October 2018 and subsequently revised in November 2018 and March 2019 (the “VIE Agreements”) with these PRC domestic companies and their respective shareholders. After that Lishui Mengxiang VIE, Lianwai Kindergarten and Liandu Foreign Language School VIE (“affiliate Chinese entities”) became VIEs on October 2018 respectively, whose primary beneficiary is Liandu WFOE, and the shareholders of these affiliate Chinese entities became the Nominee Shareholders at that date. Reorganization is accounted for as a common control transaction under the pooling of interest method. Accordingly, the accompanying consolidated financial statements have been prepared as if the current corporate structure had been in existence throughout the periods. These contractual agreements cannot be unilaterally terminated by the Nominee Shareholders or the affiliate Chinese entities. As a result, the Company maintains the ability to control these affiliate Chinese entities and is entitled to substantially all of the economic benefits from these affiliate Chinese entities. As such, the Group consolidated the financial results of these affiliate Chinese entities in the Group’s consolidated financial statements from the date the Company took control of them. The principal terms of the agreements entered into amongst the VIEs, their respective shareholders and the Liandu WFOE are further described below. (c) Contractual Agreements with VIEs Loan Agreements Pursuant to the loan agreements entered into between Liandu WFOE and VIEs, Liandu WFOE can grant interest-free loans to Lishui Mengxiang VIE with the sole purpose of providing funds necessary for the business operations and development of Liandu Foreign Language School. These business loan amounts can be injected into Liandu Foreign Language School as capital or other operation means, and cannot be accessed for any personal uses. There is no fixed term for each loan under the loan agreement except that Liandu WFOE can unilaterally decide when to recover the loan and the loan agreements shall remain have Exclusive Call Option Agreements Under the exclusive call option agreements entered into among the VIEs, Liandu WFOE and Nominee Shareholders, the Nominee Shareholders of the VIEs granted Liandu WFOE the exclusive and irrevocable right to purchase or to designate entities at their discretion to purchase part or all of the equity interests in the VIEs from the Nominee Shareholders, in the case that the PRC laws and regulations allows, at any time for a purchase price subject to the lowest price permitted by PRC laws and regulations. Liandu WFOE or its designated representatives have sole discretion as to when to exercise such options, either in part or in full. The VIEs and their Nominee Shareholders have agreed that without Liandu WFOE’s prior written consent, their respective Nominee Shareholders cannot sell, transfer, assign or dispose of or create any encumbrance on any of the VIEs’ equity interests, assets, and business. Also, as agreed, the VIEs cannot declare any dividend or change the capitalization structure of the VIEs and cannot enter into any loan, guarantee or investment agreements. Furthermore, the Nominee Shareholders have agreed that any proceeds but not limited to the sales of the Nominee Shareholders’ equity interest in relevant VIEs should be gratuitously paid to Liandu WFOE or one or more person(s) at their discretion. The agreements will remain in force during the operation terms of the relevant VIEs and any periods that are renewable pursuant to the PRC laws, and will terminate automatically when Liandu WFOE and/or its designated entities fully exercise their options to purchase all the equities held by Nominee Shareholders in accordance with the Exclusive Call Option Agreements. In addition, Liandu WFOE has the right to unilaterally terminate these agreements after 30 days advance written notice, while the Nominee Shareholders and relevant VIEs have no right to unilaterally terminate these agreements. Proxy Agreements and Power of Attorney for Shareholders Pursuant to the proxy agreements and power of attorney, each equity holder of Lishui Mengxiang VIE appointed the Liandu WFOE as their attorney-in-fact Proxy Agreements and Power of Attorney for School’s Sponsors and Directors Pursuant to the proxy agreements and power of attorney, the School’s sponsors and appointed directors irrevocably and specially authorized and entrusted the Liandu WFOE to exercise all rights of the School’s sponsors and directors, as permitted under PRC law. The agreements shall remain effective during the operation term of Liandu Foreign Language School and any periods that are renewable pursuant to PRC laws, and will terminate automatically when Liandu WFOE and/or its designated entities fully exercise their options to purchase all the equities held by the Nominee Shareholders in accordance with the Exclusive Call Option Agreement. In addition, the Liandu WFOE has the right to unilaterally terminate these agreements after 30 days advance written notice, while the School and the School’s sponsors and appointed directors have no right to unilaterally terminate these agreements. Business Cooperation Agreement and Exclusive Technical Services and Business Consulting Agreement Pursuant to the Business Cooperation Agreement and Exclusive Technical Services and Business Consulting Agreement, Liandu WFOE has agreed to provide the VIEs with technical services, management support services, consulting services and intellectual property licenses required for the conducting of private education business activities, including but not limited to preparation, selection and/or recommendation of schools textbooks, recruitment of teachers and other staff, training support, admissions support, public relations maintenance, market research and development, management and marketing consulting and other related services. The VIEs shall pay to Liandu WFOE service fees determined by Liandu WFOE at its sole discretion. Liandu WFOE has the right to determine the level of service fees paid and therefore receives substantially all of the economic benefits of the consolidated affiliated Chinese entities in the form of service fees. Liandu WFOE, as appropriate, will exclusively own any intellectual property rights arising from the performance of these agreements. The aforementioned agreements will terminate automatically when Liandu WFOE and/or its designated entities fully exercise their options to purchase all the equities held by the Nominee Shareholders in accordance with the Exclusive Call Option Agreements. In addition, Liandu WFOE retains the exclusive right to terminate the agreements at any time by delivering a written notice 30 days in advance to the applicable consolidated affiliate Chinese entities. Equity Pledge Agreements Pursuant to the equity pledge agreements among Liandu WFOE, Lishui Mengxiang VIE and the Nominee Shareholders of Lishui Mengxiang VIE, the Nominee Shareholders shall pledge all of their equity interests in the VIEs to Liandu WFOE as collateral for all of their payments to direct, indirect and derivate losses and losses of predictable profits of the PRC subsidiaries (“Secured Debts”) and to secure their obligations under the above agreements. In the event of a breach by the VIEs or any of their Nominee Shareholders of their contractual obligations, Liandu WFOE has the right to deal with the equity interests pledged in the following ways: i) purchasing or designating entities at their discretion to purchase part or all of the equity interests in the VIEs from the Nominee Shareholders, subject to the lowest price permitted by PRC laws and regulations; ii) selling the equity interests pledged through auction or discount, and preferentially compensated from the sales price; iii) other means agreed between Liandu WFOE and the Nominee Shareholders, after giving written notice to the Nominee Shareholders. The equity pledge agreements will expire when the Nominee Shareholders have completed all their obligations under the above agreements or the Secured Debts are fully settled, or when Liandu WFOE unilaterally delivers a written notice 30 days in advance. Spousal Undertakings Pursuant to the Spousal Undertakings, each Nominee Shareholder, who is a natural person, and their spouses unconditionally and irrevocably agreed that the equity interests in the VIEs held by and registered in the name of their spouse will be disposed of pursuant to the equity pledge agreements, the exclusive call option agreements, the loan agreement and the proxy agreement and power of attorney. Each of their spouses agreed not to assert any rights over the equity interests in the VIEs held by their respective spouses. In addition, in the event that any spouse obtains any equity interests in the VIEs held by their spouse for any reason, they agreed to be bound by similar obligations and agreed to enter into similar contractual agreements. (d) Combined financial information of the VIEs The following combined financial information of the Group’s VIEs as of December 31, 2018, 2019 and 2020 and for the years ended December 31, 2019 and 2020 was included in the accompanying consolidated financial statements of the Group as follows: VIEs As of December 31, 2019 2020 RMB RMB Assets Current assets Cash and cash equivalents 24,637,411 9,611,773 Short-term investments 20,005,217 — Accounts receivable, net 1,251,480 — Inventories 1,169,405 55,607 Amounts due from related parties (Note 21 12,754,388 — Amounts due from inter-company entities 13,749,516 62,261,944 Prepayments and other current assets 436,192 1,485,798 Total current assets 74,003,609 73,415,122 Non-current Property and equipment, net 204,193,521 204,843,872 Land use rights 38,667,172 37,720,475 Intangible assets 16,667 11,667 Other non-current 60,724 — Total non-current 242,938,084 242,576,014 Total assets 316,941,693 315,991,136 Liabilities Current liabilities Short-term borrowings 83,600,000 39,695,606 Accounts payable 9,261,689 2,926,034 Amount due to inter-company entities — 8,884,600 Deferred revenue, current 17,729,391 18,169,451 Salaries and welfare payable 13,318,001 17,341,838 Amounts due to related parties (Note 21 719,400 719,400 Taxes payable 27,226 276,919 Accrued liabilities and other current liabilities 5,763,399 5,221,410 Total current liabilities 130,419,106 93,235,258 Deferred revenue, non-current 1,712,296 412,593 Total non-current 1,712,296 412,593 Total liabilities 132,131,402 93,647,851 For the year s 2018 2019 2020 RMB RMB RMB Net revenues 142,523,585 152,120,636 155,946,729 Net income 41,002,633 47,310,815 37,532,994 Net cash provided by operating activities 52,183,386 58,830,470 47,477,961 Net cash (used in)/provided by investing activities (2,636,644 ) (34,739,000 ) 19,424,757 Net cash used in financing activities ( 82,047,964 ) (1,961,532 ) (81,928,356 ) Net (decrease)/increase in cash and cash equivalents ( 32,501,222 ) 22,129,938 (15,025,638 ) In accordance with the aforementioned agreements, the Company has the power to direct the activities of the VIEs, and have the control of their assets. Therefore the Company considers that there is no other asset in the VIEs that can be used only to settle obligations of the respective VIE, except for the education facilities assets, registered capital and the PRC statutory reserves, as of December 31, 2019 and 2020. As the VIEs are incorporated as schools and limited liability company under the PRC Company Law, the 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. As the Group is conducting certain businesses in the PRC through the VIEs, the Group may provide additional financial support on a discretionary basis in the future, which could expose the Group to a loss. The VIEs’ assets comprise both recognized and unrecognized revenue-producing assets. The recognized revenue-producing assets mainly include buildings, land use rights, computers and electronic devices. The unrecognized revenue-producing assets mainly consist of patents, trademarks and assembled workforce which are not recorded in the financial statements of the VIEs as they do not meet the recognition criteria set in ASC 350-30-25. There is no VIE where the Company has a variable interest but is not the primary beneficiary. (e) Risks associated with VIE arrangements Foreign investment in the education industry in PRC is extensively regulated and subject to various restrictions. Specifically, foreign investors are prohibited from investing in compulsory education, namely primary to middle school in the PRC. In addition, foreign investment in education institutions in the PRC must be in the form of cooperation between Chinese educational institutions and foreign educational institutions and the foreign portion of the total investment in a Sino-foreign education institute must be below 50%. The subsidiary in PRC is currently ineligible to apply for the required education licenses and permits in PRC for the operation of primary and middle schools. Although foreign investment in high schools is not prohibited, the subsidiary Liandu WFOE in PRC is still ineligible to independently or jointly invest and operate high schools. To comply with PRC laws and regulations, the Company has entered into a series of arrangements pursuant to which the wholly-owned subsidiary Liandu WFOE receives the economic benefits from the affiliated Chinese entities. If the contractual arrangements that establish the structure for operating the business in PRC are found to violate any PRC laws or regulations in the future or fail to obtain or maintain any of the required permits or approvals, the relevant PRC regulatory authorities, including the Ministry of Education of PRC, or the MOE, which regulates the education industry, would have broad discretion in dealing with such violations, including: • revoking the business and operating licenses of the affiliated Chinese entities; • discontinuing or restricting the operations of any related-party transactions among Liandu WFOE or affiliated Chinese entities; • imposing fines or other requirements with which the Company or Liandu WFOE or affiliated Chinese entities may not be able to comply; • requiring the Company to restructure the operations in such a way as to compel the Company to establish new entities, re-apply • imposing additional conditions or requirements with which the Company may not be able to comply; or • restricting the use of proceeds from the additional public offering or financing to finance the business and operations in PRC. Advised by the Company’s PRC legal counsel, the Company’s contractual arrangements with its consolidated VIEs are valid, binding and enforceable under the current laws and regulations of PRC. Based on such legal opinion and the management’s knowledge and experience, the Company believes that its contractual arrangements with its consolidated VIEs are in compliance with current PRC laws and legally enforceable. However, in the event that the affiliated Chinese entities and their respective shareholders fail to perform their contractual obligations, the Company may have to rely on the PRC legal system to enforce its rights. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the foreign investments in PRC. However, since the PRC legal system is still evolving, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit remedies available to the Company. In addition, any litigation in PRC may be protracted and result in substantial costs and diversion of resources and management attention. Due to the uncertainties with respect to the Company’s PRC legal system, the PRC government authorities may ultimately take a view contrary to the above opinion of the Company’s PRC legal counsel. There are, however, substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. Accordingly, the Company cannot be assured that the PRC government authorities will not ultimately take a view that is contrary to the Company’s belief and the opinion of its PRC legal counsel. In March 2019, the draft Foreign Investment Law was submitted to the National People’s Congress for review and was approved on March 15, 2019, which came into effect from January 1, 2020. The new Foreign Investment Law of the PRC repealed simultaneously the Wholly Foreign-owned Enterprise Law of the PRC, Sino-foreign Equity Joint Venture Law of the PRC and Sino-foreign Cooperative Joint Ventures Law of the PRC. Therefore, the general regulations for companies’ set up and operation in the PRC including the foreign-invested companies shall comply with the Company Law of the PRC unless provided in the PRC Foreign Investment Laws. In December 2019, the Implementing Regulation of the Foreign Investment Law was promulgated by the State Council and comes into force as of January 1, 2020. The Foreign Investment Law does not touch upon the relevant concepts and regulatory regimes that were historically suggested for the regulation of VIE structures, and thus this regulatory topic remains unclear under the Foreign Investment Law. Since the Foreign Investment Law is new, there are substantial uncertainties existing with respect to its implementation and interpretation and it is also possible that the VIE entities will be deemed as foreign invested enterprises and be subject to restrictions in the future. Such restrictions may cause interruptions to the operations, products and services and may incur additional compliance cost, which may in turn materially and adversely affect the business, financial condition and results of operations. In accordance with the VIE arrangements, the Group has the power to direct the activities of the VIEs, and can have control of VIEs’ assets. Therefore, the Group considers that there are no other assets of the VIEs can be used only to settle their obligations, except for the education facilities assets, registered capital and the PRC statutory reserves, as of December 31, 2019 and 2020.

Accounting Policies [Abstract]
Principal Accounting Policies	2. Principal Accounting Policies (a) Basis of preparation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized further below. (b) Use of estimates The preparation of the Group’s consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the balance sheet date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company believes that the consolidation of VIEs, depreciation of buildings and impairment assessments of long-lived assets reflect more significant estimates used in the preparation of its consolidated financial statements. Management makes the estimates based on historical experience and on various other assumptions as discussed elsewhere in the consolidated financial statements that are believed to be reasonable, the results of which form the basis for making estimates about the carrying values of assets and liabilities. Actual results could materially differ from these estimates. (c) Consolidation The Group’s consolidated financial statements include the financial statements of the Company, its subsidiaries and its VIEs for which the Company or its subsidiaries are the primary beneficiary. All transactions and balances among the Company, its subsidiaries and its VIEs have been eliminated upon consolidation. Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting powers; has the power to appoint or remove the majority of the members of the board of directors; or to cast a majority of votes at the meeting of directors; or has the power to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. A consolidated VIE is an entity in which the Company, or its subsidiary, through contractual agreements, bears the risks of, and enjoys the rewards normally associated with ownership of the entity. In determining whether the Company or its subsidiaries are the primary beneficiary, the Company considers whether it has the power to direct activities that are significant to the VIE’s economic performance, and also the Group’s obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company, through Liandu WFOE holds all the variable interests of the VIEs, and has been determined to be the primary beneficiary of the VIEs. (d) Functional currency and foreign currency translation The Group uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of PRC is the United States dollar (“US$”), while the functional currency of the PRC entities in the Group is RMB as determined based on the criteria of ASC 830, Foreign Currency Matters. Transactions denominated in other than the functional currencies are re-measured re-measured The financial statements of the Group are translated from the functional currency to the reporting currency, RMB. Assets and liabilities of the Company and its subsidiaries incorporated outside of PRC are translated into RMB at fiscal year-end (e) Convenience translation The unaudited United States dollar (“US$”) amounts disclosed in the accompanying financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the rate of US$1 = RMB 6.5250 on December 31, 2020, representing the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on December 31, 2020, or at any other rate. (f) Fair value of financial instruments 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. The established fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value include: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Observable, market-based inputs, other than quoted prices, in active markets for identical assets or liabilities. Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. Accounting guidance also describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. The Group does not have any non-financial The Group’s financial instruments consist principally of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, and other liabilities. As of December 31, 2019 and 2020, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, short-term borrowings and other liabilities approximated their fair values reported in the consolidated balance sheets due to the short term maturities of these instruments. On a recurring basis, the Group measures its short-term investments at fair value. The following table sets forth the Group’s assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy: Level 1 Level 2 Level 3 Balance at fair value As of December 31, 2019 Assets Short-term investments—wealth management products — 20,005,217 — 20,005,217 Level 1 Level 2 Level 3 Balance at fair value As of December 31, 2020 Assets Short-term investments—wealth management products — — — — (g) Cash and cash equivalents Cash and cash equivalents include cash in bank placed with banks or other financial institutions, which have original maturities of three months or less at the time of purchase and are readily convertible to known amounts of cash. (h) Short-term investments Short-term investments include investments in wealth management products issued by certain banks with maturities between three months and one year. The wealth management products are unsecured with variable interest rates. In accordance with ASC 825, for investments in financial instruments with a variable interest rate referenced to performance of underlying assets, the Group elected to use the fair value method at the date of initial recognition and carried these investments at fair value. Changes in the fair value are reflected in the consolidated statements of operations and comprehensive income as change in fair value of short-term investments. Fair value is estimated based on quoted prices of similar products provided by banks at the end of each period. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. (i) Accounts receivable, net Accounts receivable primarily consists of receivables from cooperation partners for campus events and receivables for learning materials from students. Accounts receivable are presented net of any allowance for doubtful accounts. The Group uses specific identification in providing for bad debts when facts and circumstances indicate that collection is doubtful and based on factors listed in the following paragraph. If the financial conditions of its customers were to deteriorate, resulting in an impairment of their ability to make payments, an additional allowance may be required. The Company maintains an allowance for doubtful accounts which reflects its best estimate of amounts that potentially will not be collected. The Company determines the allowance for doubtful accounts on a specific identification basis by taking into consideration various factors including but not limited to historical collection experience and credit-worthiness of the customers as well as the age of the individual receivables balance. Additionally, the Company makes specific bad debt provisions based on any specific knowledge the Company has acquired that might indicate that an account is uncollectible. The facts and circumstances of each account may require the Company to use substantial judgment in assessing its collectability. (j) Inventories Inventories are stated at the lower of cost or net realized value. Cost is determined using the weighted average method. As of each reporting date, the Group evaluates the net realizable value based on assumptions about future customer demand and market conditions. The evaluation may take into consideration inventory aging, expected demand, anticipated sales price, and other factors. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. As of December 31, 2019, inventories mainly included uniforms and food of RMB 1.01 million and RMB 0.06 million, respectively. As of December 31, 2020, inventories mainly included uniforms and food of RMB 1.44 million and RMB 0.06 million, respectively. There was no write-down of inventories for the years (k) Property and equipment, net Property and equipment are stated at historical cost less accumulated depreciation and impairment income, if any. Depreciation is calculated using the straight-line method over their estimated useful lives. The estimated useful lives are as follows: Buildings 10 years to 50 years Motor vehicles 5 years Electronic devices and other general equipment 2 years to 5 years Expenditures for maintenance and repairs are expensed as incurred. The gain or income on the disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of comprehensive income. (l) Land use rights, net Land use rights are recorded at cost less accumulated amortization. Amortization is provided over the term of the land use rights agreement on a straight-line basis over the term of the agreement, which is 50 years. (m) Impairment of long-lived assets For other long-lived assets including property and equipment, other non-current The Group did not recognize any impairment loss for the years ended December 31, 2018, 2019 and 2020. (n) Deferred revenue Cash proceeds received from customers are initially recorded as deferred revenue and are recognized as revenues when revenue recognition criteria are met. (o) Revenue recognition The Group adopted ASC 606, “Revenue from Contracts with Customers” for all periods presented. Consistent with the criteria of Topic 606, the Group follows five steps for its revenue recognition: (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 mainly offers primary and middle school education services to students from grade 1 to grade 9. During the stay in school, the students are offered meals (including breakfast, lunch, dinner and snacks) and accommodation. Both the meal fees and accommodation fees are collected in advance prior to the beginning of each semester. The School provides school uniforms to the students with payment also made prior to the beginning of each semester. The School asks students to purchase certain designated additional learning materials, such as after-class reading books related to the courses provided. Students may choose to either purchase from bookstores by themselves or order from the School. The payments for learning materials are collected at the end of each semester. The Group also offered kindergarten care services during the track period before its disposal of Lianwai Kindergarten in November 2018. Tuition, meal and accommodation service income Tuition, meal and accommodation service income are generally received in advance prior to the beginning of each semester of a school year, and are initially recorded as deferred revenue. Tuition, meal and accommodation service income are recognized over time during the service period of each semester. Amounts which will be earned within one year are reflected as a current liability, and those which will be earned beyond one year are reflected as a non-current The Group recognizes service income on a gross basis, as the Group is responsible for fulfilling the promise to provide the education, meal and accommodation services to students. Financing component included in tuition fees Some contracts contain a financing component because payment by the customer occurs significantly before performance of the obligation. The Group takes the practical expedient and will not adjust the impact of a financing component for deferred revenue which will be earned within one year. The Group does not adjust the impact of a financing component for deferred revenue which will be earned beyond one year as the portion of financing component is immaterial. Sale of uniforms and learning materials The School sells uniform and learning materials to students. Revenue from uniform and learning materials are recognized at a point in time when control of the uniforms and learning materials have been transferred and accepted by the students. The Group recognizes revenue from sale of uniform and learning materials on a gross basis, as the Group controls the goods before they are transferred to the students. The Group is responsible for the design of uniforms and has inventory risk for the uniforms and learning materials. (p) Leases The Group assesses at contract inception whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Group as a lessor When the Group acts as a lessor, it classifies at lease inception (or when there is a lease modification) each of its leases as either an operating lease or a finance lease. Leases in which the Group does not transfer substantially all the risks and rewards incidental to ownership of an asset are classified as operating leases. Rental income is accounted for on a straight-line basis over the lease terms and is included in revenue in the statement of profit or loss due to its operating nature. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income. (q) Cost of revenues Cost of revenues consist of expenditures incurred in the generation of the Group’s revenue, includes but not limited to the salary and welfare for teachers, food costs, uniform and learning materials cost, utilities charges and depreciations. (r) General and administrative expenses General and administrative expenses consist primarily of salary and welfare for general and administrative personnel, general office expenses and professional service fees. (s) Government subsidies Government subsidies primarily consist of financial subsidies received from local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. There are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. The government subsidies with no further conditions to be met are recorded as “Other income, net” when received. The government subsidies with certain operating conditions are recorded as liabilities when received and will be recorded as operating income when the conditions are met. For the years ended December 31, 2018, 2019 RMB 7,227,318, RMB 5,857,993 and RM B 9,860,106 from the local PRC government authorities, respectively. (t) Employee social security and welfare benefits Employees of the Group in the PRC are entitled to staff welfare benefits including pension, work-related injury benefits, maternity insurance, medical insurance, unemployment benefit and housing fund plans through a PRC government-mandated multi-employer defined contribution plan. The Group is required to contribute to the plan based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed and no legal obligation beyond the contributions made. (u) Income taxes Current income taxes are provided on the basis of net income for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for income tax purposes, in accordance with the regulations of the relevant tax jurisdictions. Deferred income taxes are accounted for using an asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purpose. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive income in the period of change. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized. Uncertain tax positions The guidance on accounting for uncertainties in income taxes prescribes a more likely than not threshold for financial statements recognition and measurement of a tax position taken or expected to be taken in a tax return. Guidance was also provided on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. Significant judgment is required in evaluating the Group’s uncertain tax positions and determining its provision for income taxes. The Group did not recognize any significant interest and penalties associated with uncertain tax positions for the years ended December 31, 2018, 2019 and 2020. As of December 31, 2019 and 2020, the Group did not have any significant unrecognized uncertain tax positions. (v) Statutory reserves As stipulated by the relevant PRC laws and regulations applicable to the Group’s entities in the PRC, the Group is required to make appropriations from net income as determined in accordance with the PRC GAAP to non-distributable after-tax In the private school sector, the Implementing Regulations for the Law of the People’s Republic of China on the Promotion of Privately-run Schools require that after-tax December 31, 2018, 2019 RMB 12,725,098, RMB (w) Related parties Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or significant influence, such as a family member or relative, shareholder, or a related corporation. (x) Dividends Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2018, 2019 and 2020, respectively. The Group does not have any present plan to pay any dividends on ordinary shares in the foreseeable future. The Group currently intends to retain the available funds and any future earnings to operate and expand its business. (y) Earnings per share Basic income per share is computed by dividing net income attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the year. Diluted income per share is calculated by dividing net income attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalents shares outstanding during the year. Dilutive equivalent shares are excluded from the computation of diluted income per share if their effects would be anti-dilutive. (z) Comprehensive income Comprehensive income is defined as the change in shareholders’ equity of the Company during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Comprehensive income is reported in the consolidated statements of comprehensive income. Accumulated other comprehensive income of the Group includes the foreign currency translation adjustments. (aa) Segment reporting Operating segments are defined as components of an enterprise engaging in businesses activities for which separate financial information is available that is regularly evaluated by the Group’s chief operating decision makers in deciding how to allocate resources and assess performance. Before the disposal of Lianwai Kindergarten on November 28, 2018, the Company had two reportable segments, the kindergarten care service provided by Lianwai Kindergarten and the primary and middle school education business from grade 1 to grade 9 provided by Liandu Foreign Language School VIE. Accordingly, the financial statements for the year ended December 31, 2018 include segment information which reflects the current composition of the reportable segments in accordance with ASC Topic 280, Segment Reporting For the year ended December 31, 2019, the Company had one reportable segment for the primary and middle school education business from grade 1 to grade 9, provided by Liandu Foreign Language School VIE. The Group’s chief operating decision maker has been identified as the Chief Executive Officer, who reviews consolidated results including revenue, gross profit and operating profit at a consolidated level only. The Group does not distinguish between markets for the purpose of making decisions about resources allocation and performance assessment. The Group does not have any other geography besides the PRC that has above 10% of revenues or long-lived assets. Hence, the Group has only one operating segment and one reportable segment. (ab) Recently issued accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to recognize assets and liabilities for all leases with lease terms of more than 12 months on the balance sheets. Under the new guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will depend on its classification as a finance or operating lease. The Group will be required to recognize and measure leases existing at, or entered into after, the beginning of the earliest comparative period presented using a modified retrospective approach, with certain practical expedients available. For the Group, this ASU is effective for fiscal years beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022. The Group will not early adopt this ASU and is in the process of evaluating the impact of adopting this standard. In June 2016, the FASB issued ASU 2016-13, available-for-sale 2019-04, 2019-05, 2019-11, 2016-13. In August 2018, the FASB issued ASU 2018-13 In December 2019, the FASB issued ASU 2019-12—Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU provides an exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. This update also (1) requires an entity to recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, (2) requires an entity to evaluate when a step-up in the tax basis of goodwill should be considered part of the business combination in which goodwill was originally recognized for accounting purposes and when it should be considered a separate transaction, and (3) requires that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The standard is effective for the Company for fiscal years beginning after December 15, 2020. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.

Risk And Concentration [Abstract]
Risks and Concentration	3. Risks and Concentration (a) PRC regulations (1) Uncertainties with respect to the Implementing Regulations for the Law of the People’s Republic of China on the Promotion of Privately-run On August 10, 2018, the Ministry of Justice of the PRC, (or the “MOJ”), released the MOJ Draft for Comments for public review, which made certain significant changes to some provisions of the Implementation Rules for the Law for Promoting Private Education of the PRC, or the Implementation Rules. The MOJ has not provided the timeframe for the Implementation Rules. As of April 30 The MOJ Draft for Comments stipulates provisions of the operation and management of private schools. The provisions and the related risks of the MOJ Draft for Comments mainly include: • Foreign investment enterprises established in China and social organizations for which the foreign party is the actual controller shall not establish, participate in establishment of, or control private schools providing compulsory education. • Social organizations which adopt centralized school management models are not allowed to control non-profit • Private schools which have transactions with related parties shall follow the principles of openness, fairness, and justice and shall not damage national interests, school interests, and teacher and student rights. Any material, long-term or recurring agreement entered into between a non-profit The Group assessed the related risk of the MOJ Draft for Comments and believes: • The actual controller of the Group, Ms. Fen Ye, is a natural person of Chinese nationality, the Group believes it does not fall under the circumstances specified as a social organization for which the foreign party is the actual controller; • The Group currently operates only one school and so will not be generally recognized as adopting “centralized school management models”, and there are no express restrictions on acquiring control of for-profit non-profit • The Group’s contractual arrangements may be regarded as related-party transactions of Liandu Foreign Language School and the Group may incur compliance costs for establishing disclosure mechanisms and undergoing review and audit by the relevant government authorities. Government authorities may also consider that one or more agreements underlying the contractual arrangements do not comply with applicable PRC laws and regulations and the contractual arrangements may be required to be amended or to accommodate other more stringent regulatory requirements. Given the evolving regulatory environment, there is uncertainty as to the effective time and the provisions of the Implementation Rules and how they will be implemented and interpreted. Further, if the new implementing regulations on the Law for Promoting Private Education are officially promulgated in the near future, the local competent authorities will, in general, issue local implementation rules with which the Group is also required to comply. The Group continually monitors its business and follows the development/changes in the regulatory environment, to ensure its compliance with the requirements of Implementation Rules, which have been or will be effective, so as to reduce the risk of materially and adversely affecting the Group’s business, financial condition and results of operations. (b) Foreign exchange risk The Group’s sales, purchase and expense transactions are generally denominated in RMB and a significant portion of the Group’s liabilities are denominated in RMB. RMB is not freely convertible into foreign currencies. In the PRC, foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China. In addition, the Group’s cash denominated in US$ subject the Group to risks associated with changes in the exchange rate of RMB against US$ and may affect the Group’s results of operations going forward. (c) Credit and concentration risk The Group’s credit risk arises from cash and cash equivalents, short-term investments, prepayments and other current assets, and accounts receivable. The carrying amounts of these financial instruments represent the maximum amount of income due to credit risk. The Group expects that there is no significant credit risk associated with the cash and cash equivalents and short-term investments which are held by reputable financial institutions in the jurisdictions where the Company, its subsidiaries and VIEs are located. The Group believes that it is not exposed to unusual risks as these financial institutions have high credit quality. The Group has no significant concentrations of credit risk with respect to its prepayments. Accounts receivable are typically unsecured and are derived from revenue earned either directly from customers. The risk with respect to accounts receivable is mitigated by credit evaluations performed on them. (i) Concentration of revenues No single customer represented 10% or more of the Group’s net revenues for the years ended December 31, 2018, 2019 and 2020. (ii) Concentration of accounts receivable The Group has not experienced any significant recoverability issue with respect to its accounts receivable. The Group conducts credit evaluations on its customers and generally does not require collateral or other security from such customers. The Group periodically evaluates the creditworthiness of the existing customers in determining an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. The following table summarized party with greater than 10% of the accounts receivable: As of December 31, 2019 2020 Customer A(*) 31 % — Customer A is the cooperation partner, with whom the Group provided campus events to participants referred by this partner.

There are no significant differences between US GAAP and PRC accounting standards in connection with the reported net assets of the legally owned subsidiary in the PRC and the VIE. Even though the Company currently does not require any such dividends, loans or advances from the PRC entities for working capital and other funding purposes, the Company may in the future require additional cash resources from them due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends or distributions to the shareholders. Except for the above, there is no other restriction on use of proceeds generated by the Group’s subsidiaries and the VIEs to satisfy any obligations of the Company.

Principal Accounting Policies (

Principal Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of preparation	(a) Basis of preparation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized further below.
Use of estimates	(b) Use of estimates The preparation of the Group’s consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the balance sheet date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company believes that the consolidation of VIEs, depreciation of buildings and impairment assessments of long-lived assets reflect more significant estimates used in the preparation of its consolidated financial statements. Management makes the estimates based on historical experience and on various other assumptions as discussed elsewhere in the consolidated financial statements that are believed to be reasonable, the results of which form the basis for making estimates about the carrying values of assets and liabilities. Actual results could materially differ from these estimates.
Consolidation	(c) Consolidation The Group’s consolidated financial statements include the financial statements of the Company, its subsidiaries and its VIEs for which the Company or its subsidiaries are the primary beneficiary. All transactions and balances among the Company, its subsidiaries and its VIEs have been eliminated upon consolidation. Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting powers; has the power to appoint or remove the majority of the members of the board of directors; or to cast a majority of votes at the meeting of directors; or has the power to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. A consolidated VIE is an entity in which the Company, or its subsidiary, through contractual agreements, bears the risks of, and enjoys the rewards normally associated with ownership of the entity. In determining whether the Company or its subsidiaries are the primary beneficiary, the Company considers whether it has the power to direct activities that are significant to the VIE’s economic performance, and also the Group’s obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company, through Liandu WFOE holds all the variable interests of the VIEs, and has been determined to be the primary beneficiary of the VIEs.
Functional currency and foreign currency translation	(d) Functional currency and foreign currency translation The Group uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of PRC is the United States dollar (“US$”), while the functional currency of the PRC entities in the Group is RMB as determined based on the criteria of ASC 830, Foreign Currency Matters. Transactions denominated in other than the functional currencies are re-measured re-measured The financial statements of the Group are translated from the functional currency to the reporting currency, RMB. Assets and liabilities of the Company and its subsidiaries incorporated outside of PRC are translated into RMB at fiscal year-end
Convenience translation	(e) Convenience translation The unaudited United States dollar (“US$”) amounts disclosed in the accompanying financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the rate of US$1 = RMB 6.5250 on December 31, 2020, representing the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on December 31, 2020, or at any other rate.
Fair value of financial instruments	(f) Fair value of financial instruments 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. The established fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value include: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Observable, market-based inputs, other than quoted prices, in active markets for identical assets or liabilities. Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. Accounting guidance also describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. The Group does not have any non-financial The Group’s financial instruments consist principally of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, and other liabilities. As of December 31, 2019 and 2020, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, short-term borrowings and other liabilities approximated their fair values reported in the consolidated balance sheets due to the short term maturities of these instruments. On a recurring basis, the Group measures its short-term investments at fair value. The following table sets forth the Group’s assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy: Level 1 Level 2 Level 3 Balance at fair value As of December 31, 2019 Assets Short-term investments—wealth management products — 20,005,217 — 20,005,217 Level 1 Level 2 Level 3 Balance at fair value As of December 31, 2020 Assets Short-term investments—wealth management products — — — —
Cash and cash equivalents	(g) Cash and cash equivalents Cash and cash equivalents include cash in bank placed with banks or other financial institutions, which have original maturities of three months or less at the time of purchase and are readily convertible to known amounts of cash.
Short-term investments	(h) Short-term investments Short-term investments include investments in wealth management products issued by certain banks with maturities between three months and one year. The wealth management products are unsecured with variable interest rates. In accordance with ASC 825, for investments in financial instruments with a variable interest rate referenced to performance of underlying assets, the Group elected to use the fair value method at the date of initial recognition and carried these investments at fair value. Changes in the fair value are reflected in the consolidated statements of operations and comprehensive income as change in fair value of short-term investments. Fair value is estimated based on quoted prices of similar products provided by banks at the end of each period. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements.
Accounts receivable, net	(i) Accounts receivable, net Accounts receivable primarily consists of receivables from cooperation partners for campus events and receivables for learning materials from students. Accounts receivable are presented net of any allowance for doubtful accounts. The Group uses specific identification in providing for bad debts when facts and circumstances indicate that collection is doubtful and based on factors listed in the following paragraph. If the financial conditions of its customers were to deteriorate, resulting in an impairment of their ability to make payments, an additional allowance may be required. The Company maintains an allowance for doubtful accounts which reflects its best estimate of amounts that potentially will not be collected. The Company determines the allowance for doubtful accounts on a specific identification basis by taking into consideration various factors including but not limited to historical collection experience and credit-worthiness of the customers as well as the age of the individual receivables balance. Additionally, the Company makes specific bad debt provisions based on any specific knowledge the Company has acquired that might indicate that an account is uncollectible. The facts and circumstances of each account may require the Company to use substantial judgment in assessing its collectability.
Inventories	(j) Inventories Inventories are stated at the lower of cost or net realized value. Cost is determined using the weighted average method. As of each reporting date, the Group evaluates the net realizable value based on assumptions about future customer demand and market conditions. The evaluation may take into consideration inventory aging, expected demand, anticipated sales price, and other factors. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. As of December 31, 2019, inventories mainly included uniforms and food of RMB 1.01 million and RMB 0.06 million, respectively. As of December 31, 2020, inventories mainly included uniforms and food of RMB 1.44 million and RMB 0.06 million, respectively. There was no write-down of inventories for the years
Property and equipment, net	(k) Property and equipment, net Property and equipment are stated at historical cost less accumulated depreciation and impairment income, if any. Depreciation is calculated using the straight-line method over their estimated useful lives. The estimated useful lives are as follows: Buildings 10 years to 50 years Motor vehicles 5 years Electronic devices and other general equipment 2 years to 5 years Expenditures for maintenance and repairs are expensed as incurred. The gain or income on the disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of comprehensive income.
Land use rights, net	(l) Land use rights, net Land use rights are recorded at cost less accumulated amortization. Amortization is provided over the term of the land use rights agreement on a straight-line basis over the term of the agreement, which is 50 years.
Impairment of long-lived assets	(m) Impairment of long-lived assets For other long-lived assets including property and equipment, other non-current The Group did not recognize any impairment loss for the years ended December 31, 2018, 2019 and 2020.
Deferred revenue	(n) Deferred revenue Cash proceeds received from customers are initially recorded as deferred revenue and are recognized as revenues when revenue recognition criteria are met.
Revenue recognition	(o) Revenue recognition The Group adopted ASC 606, “Revenue from Contracts with Customers” for all periods presented. Consistent with the criteria of Topic 606, the Group follows five steps for its revenue recognition: (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 mainly offers primary and middle school education services to students from grade 1 to grade 9. During the stay in school, the students are offered meals (including breakfast, lunch, dinner and snacks) and accommodation. Both the meal fees and accommodation fees are collected in advance prior to the beginning of each semester. The School provides school uniforms to the students with payment also made prior to the beginning of each semester. The School asks students to purchase certain designated additional learning materials, such as after-class reading books related to the courses provided. Students may choose to either purchase from bookstores by themselves or order from the School. The payments for learning materials are collected at the end of each semester. The Group also offered kindergarten care services during the track period before its disposal of Lianwai Kindergarten in November 2018. Tuition, meal and accommodation service income Tuition, meal and accommodation service income are generally received in advance prior to the beginning of each semester of a school year, and are initially recorded as deferred revenue. Tuition, meal and accommodation service income are recognized over time during the service period of each semester. Amounts which will be earned within one year are reflected as a current liability, and those which will be earned beyond one year are reflected as a non-current The Group recognizes service income on a gross basis, as the Group is responsible for fulfilling the promise to provide the education, meal and accommodation services to students. Financing component included in tuition fees Some contracts contain a financing component because payment by the customer occurs significantly before performance of the obligation. The Group takes the practical expedient and will not adjust the impact of a financing component for deferred revenue which will be earned within one year. The Group does not adjust the impact of a financing component for deferred revenue which will be earned beyond one year as the portion of financing component is immaterial. Sale of uniforms and learning materials The School sells uniform and learning materials to students. Revenue from uniform and learning materials are recognized at a point in time when control of the uniforms and learning materials have been transferred and accepted by the students. The Group recognizes revenue from sale of uniform and learning materials on a gross basis, as the Group controls the goods before they are transferred to the students. The Group is responsible for the design of uniforms and has inventory risk for the uniforms and learning materials.
Leases	(p) Leases The Group assesses at contract inception whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Group as a lessor When the Group acts as a lessor, it classifies at lease inception (or when there is a lease modification) each of its leases as either an operating lease or a finance lease. Leases in which the Group does not transfer substantially all the risks and rewards incidental to ownership of an asset are classified as operating leases. Rental income is accounted for on a straight-line basis over the lease terms and is included in revenue in the statement of profit or loss due to its operating nature. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income.
Cost of revenues	(q) Cost of revenues Cost of revenues consist of expenditures incurred in the generation of the Group’s revenue, includes but not limited to the salary and welfare for teachers, food costs, uniform and learning materials cost, utilities charges and depreciations.
General and administrative expenses	(r) General and administrative expenses General and administrative expenses consist primarily of salary and welfare for general and administrative personnel, general office expenses and professional service fees.
Government subsidies	(s) Government subsidies Government subsidies primarily consist of financial subsidies received from local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. There are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. The government subsidies with no further conditions to be met are recorded as “Other income, net” when received. The government subsidies with certain operating conditions are recorded as liabilities when received and will be recorded as operating income when the conditions are met. For the years ended December 31, 2018, 2019 RMB 7,227,318, RMB 5,857,993 and RM B 9,860,106 from the local PRC government authorities, respectively.
Employee social security and welfare benefits	(t) Employee social security and welfare benefits Employees of the Group in the PRC are entitled to staff welfare benefits including pension, work-related injury benefits, maternity insurance, medical insurance, unemployment benefit and housing fund plans through a PRC government-mandated multi-employer defined contribution plan. The Group is required to contribute to the plan based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed and no legal obligation beyond the contributions made.
Income taxes	(u) Income taxes Current income taxes are provided on the basis of net income for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for income tax purposes, in accordance with the regulations of the relevant tax jurisdictions. Deferred income taxes are accounted for using an asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purpose. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive income in the period of change. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized. Uncertain tax positions The guidance on accounting for uncertainties in income taxes prescribes a more likely than not threshold for financial statements recognition and measurement of a tax position taken or expected to be taken in a tax return. Guidance was also provided on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. Significant judgment is required in evaluating the Group’s uncertain tax positions and determining its provision for income taxes. The Group did not recognize any significant interest and penalties associated with uncertain tax positions for the years ended December 31, 2018, 2019 and 2020. As of December 31, 2019 and 2020, the Group did not have any significant unrecognized uncertain tax positions.
Statutory reserves	(v) Statutory reserves As stipulated by the relevant PRC laws and regulations applicable to the Group’s entities in the PRC, the Group is required to make appropriations from net income as determined in accordance with the PRC GAAP to non-distributable after-tax In the private school sector, the Implementing Regulations for the Law of the People’s Republic of China on the Promotion of Privately-run Schools require that after-tax December 31, 2018, 2019 RMB 12,725,098, RMB
Related parties	(w) Related parties Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or significant influence, such as a family member or relative, shareholder, or a related corporation.
Dividends	(x) Dividends Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2018, 2019 and 2020, respectively. The Group does not have any present plan to pay any dividends on ordinary shares in the foreseeable future. The Group currently intends to retain the available funds and any future earnings to operate and expand its business.
Earnings per share	(y) Earnings per share Basic income per share is computed by dividing net income attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the year. Diluted income per share is calculated by dividing net income attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalents shares outstanding during the year. Dilutive equivalent shares are excluded from the computation of diluted income per share if their effects would be anti-dilutive.
Comprehensive income	(z) Comprehensive income Comprehensive income is defined as the change in shareholders’ equity of the Company during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Comprehensive income is reported in the consolidated statements of comprehensive income. Accumulated other comprehensive income of the Group includes the foreign currency translation adjustments.
Segment reporting	(aa) Segment reporting Operating segments are defined as components of an enterprise engaging in businesses activities for which separate financial information is available that is regularly evaluated by the Group’s chief operating decision makers in deciding how to allocate resources and assess performance. Before the disposal of Lianwai Kindergarten on November 28, 2018, the Company had two reportable segments, the kindergarten care service provided by Lianwai Kindergarten and the primary and middle school education business from grade 1 to grade 9 provided by Liandu Foreign Language School VIE. Accordingly, the financial statements for the year ended December 31, 2018 include segment information which reflects the current composition of the reportable segments in accordance with ASC Topic 280, Segment Reporting For the year ended December 31, 2019, the Company had one reportable segment for the primary and middle school education business from grade 1 to grade 9, provided by Liandu Foreign Language School VIE. The Group’s chief operating decision maker has been identified as the Chief Executive Officer, who reviews consolidated results including revenue, gross profit and operating profit at a consolidated level only. The Group does not distinguish between markets for the purpose of making decisions about resources allocation and performance assessment. The Group does not have any other geography besides the PRC that has above 10% of revenues or long-lived assets. Hence, the Group has only one operating segment and one reportable segment.
Recently issued accounting pronouncements	(ab) Recently issued accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to recognize assets and liabilities for all leases with lease terms of more than 12 months on the balance sheets. Under the new guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will depend on its classification as a finance or operating lease. The Group will be required to recognize and measure leases existing at, or entered into after, the beginning of the earliest comparative period presented using a modified retrospective approach, with certain practical expedients available. For the Group, this ASU is effective for fiscal years beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022. The Group will not early adopt this ASU and is in the process of evaluating the impact of adopting this standard. In June 2016, the FASB issued ASU 2016-13, available-for-sale 2019-04, 2019-05, 2019-11, 2016-13. In August 2018, the FASB issued ASU 2018-13 In December 2019, the FASB issued ASU 2019-12—Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU provides an exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. This update also (1) requires an entity to recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, (2) requires an entity to evaluate when a step-up in the tax basis of goodwill should be considered part of the business combination in which goodwill was originally recognized for accounting purposes and when it should be considered a separate transaction, and (3) requires that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The standard is effective for the Company for fiscal years beginning after December 15, 2020. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
