(“Youdao Guangzhou Computer”) Guangzhou, China, 2021 100 % Providing online learning services (b) VIE arrangements i) Contracts that give the Company the power to direct activities of the VIEs Current PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in value-added telecommunication services and certain other businesses. Youdao Information and Youdao Hangzhou, the PRC subsidiaries, are considered foreign-invested enterprises. To comply with the foregoing restrictions imposed by PRC laws and regulations on foreign investments, the Group conducts a significant portion of businesses in China through Youdao Computer, Linjiedian Education and Youdao Guangzhou Computer, the VIEs in the PRC, based on a series of contractual arrangements between the Company’s subsidiaries and the VIEs and their respective shareholders. The following is a summary of the contractual arrangements by and among Youdao Information, Youdao Computer and the shareholders of Youdao Computer. The contractual arrangements with the other VIEs and their respective shareholders, except for the cooperation agreements, are substantially similar to the corresponding contractual arrangements as discussed below. Loan Agreements Each shareholder of Youdao Computer, William Lei Ding and Feng Zhou, entered into a loan agreement with Youdao Information under which, Youdao Information provided each of William Lei Ding and Feng Zhou with an interest-free loan in the principal amount of approximately RMB3.6 million and RMB1.4 million, respectively. These funds were used by each of William Lei Ding and Feng Zhou to pay the consideration to acquire his respective equity interest in Youdao Computer. Such loans can be repaid by transferring each of William Lei Ding and Feng Zhou’s respective equity interest in Youdao Computer to Youdao Information or its designee or through such other method as Youdao Information shall determine. The term of each of the Loan Agreements is 10 years from the date of loan agreement and will be automatically extended for a further 10-year Exclusive Purchase Option Agreements Under the Exclusive Purchase Option Agreements entered into by Youdao Information, Youdao Computer and each of William Lei Ding and Feng Zhou, Youdao Computer granted Youdao Information an option to purchase all or a portion of the respective equity interests in Youdao Computer at a price equal to the original capital and any additional paid-in Shareholder Voting Right Trust Agreements Under the Shareholder Voting Right Trust Agreements between Youdao Information and each of William Lei Ding and Feng Zhou, respectively, each of William Lei Ding and Feng Zhou, agreed to irrevocably entrust a person designated by Youdao Information to represent him to exercise all the voting right and other shareholders’ rights to which he is entitled as a shareholder of Youdao Computer. Each Shareholder Voting Right Trust Agreement shall remain effective for as long as William Lei Ding and Feng Zhou, as applicable, remains a shareholder of Youdao Computer unless Youdao Information unilaterally terminates the agreement by written notice. Equity Pledge Agreements Each of William Lei Ding and Feng Zhou entered into an Equity Pledge Agreement with Youdao Information. Under such Equity Pledge Agreements, each of William Lei Ding and Feng Zhou pledged his respective equity interest in Youdao Computer to Youdao Information to secure his obligations under the applicable Loan Agreement, Exclusive Purchase Option Agreement, Shareholder Voting Right Trust Agreement, and Operating Agreement. Each of William Lei Ding and Feng Zhou further agreed not to transfer or pledge his respective equity interest in Youdao Computer without the prior written consent of Youdao Information. Each of the Equity Pledge Agreements will remain binding until the respective pledger, William Lei Ding or Feng Zhou, as the case may be, discharges all his obligations under the above-mentioned agreements. ii) Contracts that enable the Company to receive substantially all of the economic benefits from the VIEs Operating Agreements Each of Youdao Computer, William Lei Ding and Feng Zhou agreed that, except for transactions in the ordinary course of business, Youdao Computer will not enter into any transaction that would materially affect the assets, liabilities, rights or operations of Youdao Computer without the prior written consent of Youdao Information. Youdao Information also agreed that it would provide performance guarantees and, at Youdao Information’s discretion, guarantee loans for working capital purposes to the extent required by Youdao Computer for its operations. As counter-guarantee, Youdao Computer agreed to pledge the account receivable in its operations and all of its assets to Youdao Information, which pledge has not been implemented as of the date of the report. Furthermore, each of William Lei Ding and Feng Zhou agreed that, upon instruction from Youdao Information, he would appoint Youdao Computer’s board members, president, chief financial officer and other senior executive officers. The term of each operating agreement is 20 years from the date of execution and can be extended with the written consent of Youdao Information. Cooperation Agreements Youdao Computer and Youdao Information entered into a cooperation agreement, or the Youdao Computer Cooperation Agreement, on July 1, 2015. Under the Youdao Computer cooperation agreement, Youdao Information has agreed to provide the following services to Youdao Computer: • the development of computer software (including, but not limited to, producing online advertisement and distribution and maintenance of software) and technical support and maintenance for computer software operation; • the design, development, update and upgrade of platforms for online advertisement; and • the provision of technology support, including, but not limited to, server maintenance, development of server software and related maintenance and updates. Youdao Computer has agreed to share a portion of its monthly income (after tax and expenses) with Youdao Information in accordance with certain formulas as specified in the Youdao Computer Cooperation Agreement. The agreement was effective from July 1, 2015 and will continue to be effective unless it is terminated, in case of a material breach of the agreement, by written notice of the non-breaching Linjiedian Education and Youdao Information entered into a cooperation agreement, or the Linjiedian Education Cooperation Agreement, on January 18, 2019, pursuant to which Youdao Information has agreed to provide the following services to Linjiedian Education: • the development of computer software (including, but no limited to information management software and other technical software) and technical support and maintenance for computer software operation; • licensing of software, trademark, domains, technical secrets and other associated intellectual property rights; and • the provision of research and development services in relation to education courseware and teaching support services. Linjiedian Education has agreed to share a portion of its monthly income (after tax and expenses) with Youdao Information in accordance with certain formulas as specified in the Linjiedian Education Cooperation Agreement. The agreement was effective from January 18, 2019 and will continue to be effective unless it is terminated, in case of a material breach of the agreement, by written notice of the non-breaching Youdao Guangzhou Computer and Youdao Hangzhou entered into a cooperation agreement, or the Youdao Guangzhou Computer Cooperation Agreement, on January 1, 2022, pursuant to which Youdao Hangzhou has agreed to provide the following services to Youdao Guangzhou Computer: • the development of computer software (including, but no limited to information management software and other technical software) and technical support and maintenance for computer software operation; • licensing of software, trademark, domains, technical secrets and other associated intellectual property rights; and • the provision of research and development services in relation to education courseware and teaching support services. Youdao Guangzhou Computer has agreed to share a portion of its monthly income (after tax and expenses) with Youdao Hangzhou in accordance with certain formulas as specified in the Youdao Guangzhou Computer Cooperation Agreement. The agreement was effective from January 1, 2022 and will continue to be effective unless it is terminated, in case of a material breach of the agreement, by written notice of the non-breaching The VIEs has incurred RMB2,221.2 million, RMB2,767.8 million and RMB2,881.0 million service fees to Youdao Information and Youdao Hangzhou for the years ended December 31, 2021, 2022 and 2023, respectively. iii) Risks in relation to VIE structure The nominee shareholders of the VIEs are William Lei Ding, who is the chief executive officer, director and the largest shareholder of NetEase, the Company’s controlling shareholder, Feng Zhou, who is the Chief Executive Officer of the Group, and Yinghui Wu, who is the vice president of the Group. The enforceability, and therefore the benefits, of the contractual agreements between the Company and the VIEs depend on these individuals enforcing the contracts. There is a risk that the benefits of ownership between the Company and the VIEs may not be aligned in the future. Given the significance and importance of the VIEs, there would be a significant negative impact to the Company if these contracts were not enforced. The Group’s operations depend on the VIEs to honour their contractual agreements with the Group and the Company’s ability to control the VIEs also depends on the authorization by the shareholders of the VIEs to exercise voting rights on all matters requiring shareholder approval in the VIEs. The Company believes that the agreements on authorization to exercise shareholder’s voting power are legally enforceable and the possibility that it will no longer be able to control and consolidate the VIEs and VIEs’ subsidiaries as a result of the aforementioned risks and uncertainties is remote. The Company believes that its contractual arrangements with the VIEs are in compliance with PRC (the People’s Republic of China) law and are legally enforceable. William Lei Ding, Feng Zhou and Yinghui Wu have no current interest in seeking to act contrary to the contractual arrangements. However, uncertainties in the PRC legal system could limit the Company’s ability to enforce these contractual arrangements and if William Lei Ding, Feng Zhou and Yinghui Wu were to reduce their interests in the Company, their interests may diverge from that of the Company and that may potentially increase the risk that they would seek to act contrary to the contractual terms, for example by influencing the VIEs not to pay the service fees when required to do so. If the VIEs or their respective shareholder fails to perform their respective obligations under the current contractual arrangements, the Company may have to incur substantial costs and expend significant resources to enforce those arrangements and rely on legal remedies under Chinese laws. Because of the limited volume of published decisions and their non-binding In addition, many Chinese regulations are subject to extensive interpretive powers of governmental agencies and commissions, and there are substantial uncertainties regarding the interpretation and application of current and future Chinese laws and regulations. Accordingly, the Company cannot assure that Chinese regulatory authorities will not ultimately take a contrary view to its belief and will not take action to prohibit or restrict its business activities. The relevant regulatory authorities would have broad discretion in dealing with any deemed violations which may adversely impact the financial statements, operations and cash flows of the Company (including the restriction on the Company to carry out the business). If the legal structure and contractual arrangements were found to be in violation of any existing PRC laws and regulations, the PRC government could potentially: • revoke the Group’s business and operating licenses; • require the Group to discontinue or restrict operations; • restrict the Group’s right to collect revenues; • block the Group’s websites and mobile applications; • require the Group to restructure the operations in such a way as to compel the Group to establish a new enterprise, re-apply • impose additional conditions or requirements with which the Group may not be able to comply; or • take other regulatory or enforcement actions against the Group that could be harmful to its business. The imposition of any of these penalties may result in a material and adverse effect on the Group’s ability to conduct its business. In addition, if the imposition of any of these penalties causes the Group to lose the rights 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 VIEs and VIEs’ subsidiaries. The Group does not believe that any penalties imposed or actions taken by the PRC government would result in the liquidation of the Company, its subsidiaries or the VIEs. In accordance with VIE contractual agreements, the Company (1) could exercise all shareholder’s rights of the VIEs and has power to direct the activities that most significantly affects the economic performance of the VIEs, and (2) receive the economic benefits of the VIEs that could be significant to the VIEs. Accordingly, the Company was considered as ultimate primary beneficiary of the VIEs and had consolidated the VIEs’ financial results of operations, assets and liabilities in the Company’s consolidated financial statements. Therefore, the Company considers that there are no assets in the VIEs that can be used only to settle obligations of the VIEs, except for the registered capital of the VIEs amounting to approximately RMB15.0 million non-distributable There is no VIE in the Group where the Company or any subsidiary has a variable interest but is not the primary beneficiary. The following table sets forth the assets, liabilities, results of operations and cash flows of the VIEs and their subsidiaries taken as a whole, which were included in the Group’s consolidated financial statements: As of December 31, 2022 2023 RMB RMB Assets Cash and cash equivalents 238,585 199,420 Restricted cash 873 105 Short-term investments 21,356 71,848 Accounts receivable, net 170,005 198,645 Inventories 52,958 31,346 Amounts due from NetEase Group and Youdao Group 1,393,994 1,228,509 Prepayment and other current assets 90,365 71,061 Total current assets 1,968,136 1,800,934 Property, equipment and software, net 5,525 5,302 Operating lease right-of-use 31,985 47,697 Goodwill 103,006 103,006 Other assets, net 73,119 71,293 Total non-current 213,635 227,298 Total assets 2,181,771 2,028,232 Liabilities Accounts payables 49,305 45,939 Payroll payable 10,803 17,232 Amounts due to NetEase Group and Youdao Group 857,883 598,935 Contract liabilities 1,017,029 978,065 Taxes payable 19,516 23,301 Accrued liabilities and other payables 122,758 202,214 Total current liabilities 2,077,294 1,865,686 Long-term lease liabilities 22,565 29,325 Other non-current 4,498 12,698 Total non-current 27,063 42,023 Total liabilities 2,104,357 1,907,709 For the year ended December 31, 2021 2022 2023 RMB RMB RMB Net revenues: Third-party net revenues 2,750,610 3,505,470 4,132,058 Other intra-Group net revenues 941 10,512 16,871 Total net revenues 2,751,551 3,515,982 4,148,929 Cost and expenses: Third-party cost and expenses (561,272 ) (759,964 ) (1,160,224 ) Intra-Group cost and expenses related to technical consulting and related services (2,221,199 ) (2,767,812 ) (2,881,029 ) Other intra-Group cost and expenses (10,673 ) (2,685 ) (63,614 ) Total cost and expenses (2,793,144 ) (3,530,461 ) (4,104,867 ) Net (loss)/income from continuing operations (58,520 ) (31,540 ) 37,691 For the year ended December 31, 2021 2022 2023 RMB RMB RMB Cash flows from operating activities: Net cash provided by transactions with third parties 3,278,167 2,950,638 3,342,893 Net cash used in transactions with intra-Group companies related to technical consulting and related services (2,409,300 ) (2,944,165 ) (3,287,474 ) Net cash used in other transactions with intra-Group companies (699 ) (589,142 ) (47,364 ) Net cash provided by/(used in) operating activities 868,168 (582,669 ) 8,055 Cash flows from investing activities: Net cash provided by/(used in) transactions with third parties 8,550 (62,282 ) (52,988 ) Net cash provided by/(used in) investing activities 8,550 (62,282 ) (52,988 ) Cash flows from financing activities: Capital contribution to VIE — — 5,000 Net cash provided by financing activities — — 5,000 Liquidity The Group incurred net losses of RMB1,026.4 million, RMB745.9 million and RMB550.1 million for the years ended December 31, 2021, 2022 and 2023, respectively. Net cash used in operating activities was RMB1,346.4 million, RMB603.1 million and RMB438.1 million for the years ended December 31, 2021, 2022 and 2023, respectively. Accumulated deficit was RMB5,398.4 m m Historically, the Group has relied principally on both operational sources of cash and non-operational sources of financing from NetEase Group and investors to fund its operations and business development. The Group’s ability to continue as a going concern is dependent on management’s ability to successfully execute its business plan, which includes increasing revenues while controlling operating expenses, as well as, generating operational cash flows and continuing to gain support from outside sources of financing, including NetEase Group. The Group has been continuously receiving financial support from NetEase Group and according to the support letter issued by NetEase Group in April 2023, NetEase Group intends to provide financial support to the Group in the period no less than twelve months from the date of issuance of the financial statement. Refer to Note 20 for details of the Group’s relationship with NetEase Group for financing activities. In April 2021, the Group entered into an agreement with NetEase to provide US$300.0 million of revolving facility loan to the Group. The agreement was renewed in September 2023 to extend the maturity date from March 31, 2024 to March 31, 2027. As of December 31, 2023, the Group had drawn down US$89.0 million under the facility with maturity dated March 31, 2027. The Group had further drawdown US$35.2 million under the US$300.0 million revolving loan facility up to March 31, 2024. Moreover, the Group can adjust the pace of its operation expansion and control the operating expenses. Based on the above considerations, the Group believes that available loan facility and financial support from NetEase Group, will be sufficient to support the Group to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months. The Group’s consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies (a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below. (b) Principles of consolidation Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power, 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 the board 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 arrangements, has the power to direct the activities that most significantly impact the entity’s economic performance, bears the risks of and enjoys the rewards normally associated with ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity. All significant intercompany balances and transactions within the Group have been eliminated upon consolidation. (c) Discontinued operations The Group reports a disposal of its component or a group of its components as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on the Group’s operations and financial results. Classification as a discontinued operation occurs upon disposal or when the operation meets the criteria to be classified as held for sale, if earlier. In the period that a discontinued operation is classified as held for sale, the assets and liabilities of the discontinued operation are presents separately in asset and liability sections, respectively, of the consolidated balance sheets and prior periods are presented on a comparative basis. In the consolidated statements of operations and comprehensive loss, the results from discontinued operations are reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinued operations are presented separately in the consolidated statements of cash flows. Unless otherwise noted, discussion in the Notes to consolidated financial statements refers to the Group’s continuing operations. Refer to Note 3 for additional information. (d) Use of estimates The preparation of the Group’s consolidated financial statements in conformity with the U.S. GAAP requires management to make estimates and assumptions which affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the balance sheet date and reported revenues and expenses during the reported periods in the consolidated financial statements and accompanying notes. Significant accounting estimates include, but are not limited to, determination of the learning period of the customers, fair value of assets and liabilities acquired in business combinations, allowances for expected credit losses, assessment for impairment of long-lived assets, intangible assets and goodwill, lower of cost and net realizable value of inventories, valuation allowance of deferred tax assets, valuation and recognition of share-based compensation expenses. Actual results could differ from those estimates and such differences may be material to the consolidated financial statements. (e) Functional currency and foreign currency translation The Group uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company is United States dollars (“US$” or “USD”). The functional currency of the Company’s PRC subsidiaries, VIEs, VIEs’ subsidiaries as well as one subsidiary incorporated in Hong Kong is RMB. The determination of the respective functional currencies based on the criteria of ASC 830, Foreign Currency Matters In the consolidated financial statements, the financial information of the Company has been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the period. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. Net gains and losses resulting from foreign exchange transactions are included in others, net in the consolidated statements of operations and comprehensive loss. (f) Convenience translation Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into USD as of and for the year ended December 31, 2023 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB 7.0999, representing the exchange rate set forth in the H.10 statistical release of the Federal Reserve Board on December 29, 2023. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into USD at such rate. (g) Fair value measurements Fair value reflects 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 Group applies a fair value hierarchy that 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. Accounting guidance specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation techniques are observable or unobservable. The hierarchy is as follows: Level 1—Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured. Level 2—Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques. Level 3—Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Accounting guidance also describes three main approaches to measure 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. When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. Financial assets and liabilities of the Group primarily consist of cash and cash equivalents, time deposits, restricted cash, short-term investments, accounts receivable, other receivables, amounts due from/to NetEase Group, accounts payables, contract liabilities, accrued liabilities and other payables, short-term loans and long-term loans from NetEase Group of which the carrying values approximate their fair values. Please see Note 18 for additional information. (h) Cash and cash equivalents Cash and cash equivalents consist of cash on hand and demand deposits, which have original maturities less than three months and are readily convertible to known amount of cash. (i) Time deposits Time deposits represent time deposits placed with banks with original maturities of three months or more than three months but less than one year. Interest earned is recorded as interest income in the consolidated statements of operations and comprehensive loss during the periods presented. (j) Receivables, net The Group’s receivables are subject to the measurement of credit losses within the scope of ASC 326. To estimate expected credit losses, the Group has identified the relevant risk characteristics of its customers and the related receivables and other receivables which include size, type of the services or the products the Group provides, or a combination of these characteristics. Receivables with similar risk characteristics have been grouped into pools. For each pool, the Group considers the past collection experience, current economic conditions, future economic conditions (external data and macroeconomic factors) and changes in the Group’s customer collection trends. This is assessed at each quarter based on the Group’s specific facts and circumstances. (k) Investments i) Short-term investments Short-term investments include investments in financial instruments with a variable interest rate indexed to performance of underlying assets. In accordance with ASC 825, Financial Instruments, ii) Long-term investments Long-term investments are comprised of equity investments in privately-held companies and limited partnership. For investments in ordinary shares or in-substance in-substance Investments in ordinary shares or in-substance Management regularly evaluates the impairment of the equity investments without readily determinable fair value and equity method investments at each balance sheet date, or more frequently if events or circumstances indicate that the carrying amount may not be recoverable. For investments without readily determinable fair values, management performs a qualitative assessment of impairment indicators. If considered impaired, management estimates the fair value of the investment, and records an impairment in the consolidated statements of operations and comprehensive loss to the extent the carrying amount exceeds the fair value. For equity method investments, management considers if the investment is impaired when events or circumstances suggest the carrying amount may not be recoverable, and recognizes any impairment charge in the consolidated statements of operations and comprehensive loss for a decline in value that is determined to be other than temporary. (l) Inventories Inventories, consisting of smart devices and learning materials for tutoring services, are stated at the lower of cost and net realizable value. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventory to the estimated net realizable value due to slow-moving merchandise and damaged goods, which is dependent upon factors such as historical and forecasted consumer demand, and promotional environment. The Group takes ownership, risks and rewards of the products purchased. Write downs are recorded in cost of revenues in the consolidated statements of operations and comprehensive loss. (m) Property, equipment and software, net Property, equipment and software are stated at cost less accumulated depreciation and impairment, if any. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range as follows: Servers and computers 3-5 Furniture, fixtures, office and other equipment 3-5 Leasehold improvements The shorter of the useful life or term of the lease Software and others 3-5 Expenditures for maintenance and repairs are expensed as incurred. The gain or loss on the disposal of property, equipment and software is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of operations and comprehensive loss. (n) Goodwill Goodwill represents the excess of the purchase consideration over the fair value of the identifiable assets acquired and the liabilities assumed Goodwill is not amortized but is tested for impairment at the reporting unit level on an annual basis by the end of year, and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Under ASC 350-20-35, Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit. (o) Impairment of long-lived assets Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will affect the future use of the assets) indicate that the carrying value of an asset may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment for the long-lived assets by comparing the carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. The Group recognized impairment losses on intangible assets from business combination of RMB56,778, nil, and nil for the years ended December 31, 2021, 2022 and 2023, respectively. (p) Revenue recognition The Group adopted ASC 606, Revenue from Contracts with Customers Disaggregation of net revenues For the years ended December 31, 2021, 2022 and 2023, substantially all of the Group’s net revenues were generated in the PRC. The following table provides information about disaggregated revenue by types: For the year ended December 31, 2021 2022 2023 RMB RMB RMB Learning services 2,441,421 3,084,375 3,148,114 Tutoring services 2,271,036 2,886,126 2,914,064 Fee-based 170,385 198,249 234,050 Smart devices 980,424 1,256,446 909,192 Online marketing services 593,949 672,361 1,331,902 Total net revenues 4,015,794 5,013,182 5,389,208 i) Learning services Tutoring services The Group offers various types of integrated learning services, which primarily cover a wide spectrum of topics and target people from broad age groups through its diverse offerings of tutoring courses and digital learning contents, foreign languages, professional and interest education services as well as IT computer skills, etc. The Group’s tutoring courses consist of online live streaming and other activities during the online live streaming period including teaching material, quiz banks, online chat rooms, summary of lessons after each class and interactions with both students and instructors. Once the online live streaming is completed, the Group also offers the customer a content playback service. With respect to the content playback service, the customer has unlimited access to previous online live streaming courses for a specified period. The services of online live streaming, playback service, as well as the other activities provided mentioned above are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming courses and therefore are not distinct and are not sold standalone. Therefore, the Group’s tutoring courses are accounted for as a single performance obligation. This performance obligation is satisfied over the learning period of the customers. Accordingly, the Group recognizes the revenues ratably over the estimated average learning period for different courses. The Group considers the average period that customers typically spend time on the courses and other learning behavior patterns to arrive at the best estimate for the estimated learning period for each course based on the estimated learning time customers spend on the courses, the expected number of times customers will take the courses and the similarities between newly-launched The Group’s tutoring courses also consist of online pre-recorded The Group also offers digital learning contents to customers which are delivered together with online live streaming courses and customized planning services. The customers can either stream the digital learning contents online or download and watch them offline. The downloadable digital learning contents, streaming services, online live streaming courses and customized planning services are considered as distinct performance obligations in the contract. The transaction price is generally collected in advance and allocated to each performance obligation in the contract based on the relative standalone selling prices. The Group recognizes the revenues of downloadable digital learning contents as the performance obligation is satisfied upon the time of delivery. The revenues of streaming services and customized planning services are recognized ratably over the service period. For online live streaming courses, the revenues are recognized ratably over the estimated average learning period. The estimated weighted average duration of learning periods is approximately ranged from five to six months for the years ended December 31, 2021, 2022 and 2023 for both online live streaming courses and online pre-recorded There is a refund policy provided to customers for tutoring services, depending on whether the course had commenced at the time of the refund request, the length of the course, the number of sessions that the T he Group determines the transaction price to be earned by estimating the refund liabilities based on historical refund ratio on a portfolio basis using the expected value method. The Group also provides discount coupons to its customers for use in purchases on tutoring services, which are treated as a reduction of revenue when the related transaction is recognized. Fee-based Fee-based Youdao Dictionary Youdao Smart Cloud ii) Smart devices The Group sells smart devices such as Youdao Dictionary Pen, Youdao Listening Pod Youdao Smart Learning Pad Along with certain learning services, the Group also provides devices such as Youdao Smart Learning Terminal iii) Online marketing services The Group derives its online marketing revenues principally from short-term contracts. The online marketing services with display period, the contracts may consist of multiple performance obligations with a typical term of less than three months. Each performance obligation generally represents different formats of advertisement, including but not limited to banners, text-links, videos, logos, buttons and rich media. In arrangements where the Group has multiple performance obligations, the transaction price is allocated to each performance obligation using the relative stand-alone selling price. The Group generally determines stand-alone selling prices based on the prices charged to customers. If the performance obligation has not been sold separately, the Group estimates the stand-alone selling price by taking into consideration of the pricing for advertising areas of the Group’s platform with a similar popularities and advertisements with similar formats and quoted prices from competitors as well as other market conditions. Considerations allocated to each performance obligation is recognized as revenue over the individual advertisement display period, on a straight-line basis, which is usually within three months. The Group also enters into cost-per-click The Group’s online marketing services expand distribution of advertisers’ promotional links and advertisements by leveraging traffic on third parties’ internet properties, including web content, software, and mobile applications. The Group is the primary obligor to its advertisers as it is primarily responsible to the customers, bears inventory risk and has the discretion in establishing pricing. Payments made to operators of third-party internet properties are included in the traffic acquisition costs. Certain customers may receive volume rebates, which are accounted for as variable consideration. The Group estimates annual expected revenue volume with reference to their historical results and reduce revenues recognized. Practical expedients The Group has used the following practical expedients as allowed under ASC 606: (i) The effects of a significant financing component have not been adjusted for contracts which the Group expects, at contract inception, that the period between when the Group transfers a promised good or service to the customer and when the customer pays for that good or service will be one year or less. (ii) The Group applied the portfolio approach in determining the learning period of the customers given that the effect of applying a portfolio approach to a group of students’ behaviors would not differ materially from considering each one of them individually. Contract balances Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represent amounts invoiced and revenue recognized prior to invoicing, when the Group has satisfied its performance obligations and has the unconditional right to payment. Contract liabilities Contract liabilities refer to the deferred revenue and refund liabilities. Deferred revenue is relating to the learning tuition, online marketing services and fee-based premium services with fees received from customers for which the Group’s revenue recognition criteria have not been met. Revenue recognized that was included in the deferred revenue balance at January 1, 2022 and January 1, 2023 amounted to RMB941,246 and RMB987,533, respectively. As of December 31, 2023, the aggregate amount of transaction price allocated to unsatisfied performance obligations is RMB1,025.2 million which includes deferred revenue balances and amounts to be invoiced and recognized as revenue in future periods. The Group expects to recognize RMB1,008.9 million as revenue over the next 12 months. This balance does not include an estimate for variable consideration arising from sales rebates to advertising service customers. Refund liabilities represent the consideration collected by the Group which it expects to refund to its customers according to refund policy. Refund liabilities are estimated based on the historical refund ratio for each of the revenue streams. The refund liabilities were not material, as of December 31, 2022 and 2023. In the event that the actual amount of refund made exceeds the estimation, such excessive amount will be deducted from net revenues. (q) Cost of revenues Cost of revenues primarily consists of the revenue sharing and payroll expenses to instructors and tutors, traffic acquisition costs, content costs, servers and bandwidth service fees and other direct costs of providing these services as well as costs of smart devices sold. (r) Sales and marketing expenses Sales and marketing expenses mainly consist of marketing and promotional expenses, payroll related expenses and third-party service fee for outsourced sales and marketing functions. The Group expenses all advertising costs as incurred and classifies these costs under sales and marketing expenses. For the years ended December 31, 2021, 2022 and 2023, advertising expenses were RMB1,393.3 million, RMB1,479.0 million and RMB1,384.3 million, respectively. (s) Research and development expenses Research and development expenses mainly consist of personnel related expenses and technology service costs incurred for the learning courses and its development, as well as development and enhancement of the Group’s websites and applications platforms. For internal use software, the Group expenses all costs incurred for the preliminary project stage and post implementation-operation stage of development, and costs associated with repair or maintenance of the existing platforms. Costs incurred in the application development stage are capitalized and amortized over the estimated useful life. Since the amount of the Group’s research and development expenses qualifying for capitalization has been immaterial, as a result, all development costs incurred for development of internal used software have been expensed as incurred. For external use software, costs incurred for development of external use software have not been capitalized since the inception of the Group, because the period after the date technical feasibility is reached and the time when the software is marketed is short historically, and the amount of costs qualifying for capitalization has been immaterial. No costs incurred for development of learning content, products and advertising services have been capitalized because the period after the date technical feasibility is reached and the time when relevant products and services are marketed is historically short. (t) Share-based compensation The Group grants options and restricted share units, or RSUs to its employees, directors and consultants with performance conditions and service conditions. In accordance with ASC 718, Compensation-Stock Compensation The Group adopts the binomial option pricing model to determine the fair value of share options. The determination of the fair value of share options is affected by the fair value of ordinary shares as well as assumptions regarding a number of complex and subjective variables, including the expected share price volatility, actual and projected employee share option exercise behavior, risk free interest rates and expected dividends. Upon the completion of the IPO, the market price of the Company’s publicly traded ADSs is used as an indicator of fair value of ordinary shares for purposes of recording share-based compensation expenses. RSUs are measured based on the fair market value of the underlying ordinary shares on the dates of grant. Share-based compensation expenses for share options and RSUs granted with service conditions are recorded net of estimated forfeitures using graded-vesting method over the requisite service period, such that expenses are recorded only for those share-based awards that are expected to ultimately vest. The Group also recognizes compensation expenses on RSUs, granted by the Parent to the employees of the Group. RSUs are measured based on the fair market value of the underlying ordinary shares on the dates of grant. Share-based compensation expenses related are then recorded for the number of RSUs expected to vest on a graded-vesting basis, net of estimated forfeitures, over the requisite service period. (u) Employee benefits PRC Contribution Plan Full-time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to the employees. Chinese labor regulations require that the PRC subsidiaries and the VIEs of the Group make contributions to the government for these benefits based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts of such employee benefit expenses, which were expensed as incurred, were approximately RMB222,690, RMB322,168 and RMB321,025 for the years ended December 31, 2021, 2022 and 2023, respectively. (v) Taxation Income taxes Current income taxes are provided on the basis of income/(loss) 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 provided using the 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 purposes. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of operations and comprehensive loss 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 In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step two-step 50 (w) Business combinations The Group accounts for its business combination using the acquisition method of accounting in accordance with ASC 805, Business Combinations If a business combination is under common control, the acquired assets and liabilities are recognized at their historical book value. The consolidated financial statements include the results of the acquired entities from the earliest date presented or, if more recent, from the date when the entities first came under common control, regardless of the date of the combination. Consolidated financial statements for prior years would also be retrospectively adjusted for periods during which the entities were under common control. In a business combination achieved in stages, the Company remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. (x) Operating leases The Group has operating leases primarily for office space. The determination of whether an arrangement is a lease or contains a lease is made at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Group obtains substantially all of the economic benefits from and has the ability to direct the u

Discontinued Operations and Disposal Groups [Abstract]
Discontinued operations	3. Discontinued operations In September 2021, the Company’s Board of Directors approved a plan to dispose of its after-school tutoring services for academic subjects in China’s compulsory education system (the “Academic AST Business”) to an unaffiliated third party non-profit The disposal represented a strategic shift that had a major effect on the Group’s operations and financial results and was accounted for as discontinued operations. The Group has classified the historical financial results of Academic AST Business as discontinued operations in the Group’s consolidated statements of operations and comprehensive loss for all periods presented. The following table sets forth the statement of discontinued operations which was included in the Group’s consolidated financial statements: For the year ended December 31, 2021 2022   RMB     RMB   Net revenues 1,338,563 —  Cost of revenues (421,190 ) (3,972 ) Gross profit/(loss) 917,373 (3,972 ) Operating expenses: Sales and marketing expenses (862,153 ) —  Research and development expenses (97,521 ) (475 ) General and administrative expenses (57,966 ) —  Total operating expenses (1,017,640 ) (475 ) Loss from operations (100,267 ) (4,447 ) Others, net —  (1,658 ) Net loss from discontinued operations (100,267 ) (6,105 )

Concentration and Risks [Abstract]
Concentration and Risks	4. Concentration and Risks Financial instruments that potentially expose the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, time deposits, restricted cash, short-term investments and accounts receivable. As of December 31, 2022 and 2023, substantially all of the Group’s cash and cash equivalents, time deposits, restricted cash and short-term investments were held in major financial institutions located in Mainland China and Hong Kong, which management considered being of high credit quality. Accounts receivable are typically unsecured and are derived from revenues earned from reputable customers. The number of customers with a receivable balance exceeding 10% of the total accounts receivable balance is one and two as of December 31, 2022 and 2023, respectively as follows. The risk with respect to accounts receivable is mitigated by credit evaluations the Group performs on its customers and its ongoing monitoring process of outstanding balances. As of December 31, 2022 2023 Customer A *  12% Customer B  *  11% Customer C  29% * No single customer represented greater than 10 For the year ended December 31, 2021 2022 2023 Customer D     *     *  11% There was one instructor, through whom the Group’s net learning services revenue earned was more than 10% of the Group’s net learning services revenue for the years ended December 31, 2021, 2022 and 2023, respectively as follows: For the year ended December 31, 2021 2022 2023 Instructor A  *  18%  17% Instructor B  16%  *  * * The percentage was below 10% for the year.

Business Combinations [Abstract]
Business combinations	5. Business Combinations In May 2021, the Group acquired 100% equity interest of a private company, which primarily provides kids STEAM courses to its users, with cash consideration of RMB6,050. Total consideration was paid by the Group in June 2021. The Group obtained control and began to consolidate its financial statements from June 2021. The goodwill was allocated to learning services segment. Consideration for this transaction was allocated on the acquisition date based on the fair value of the assets acquired and the liabilities assumed as follows: As of the acquisition date RMB Cash consideration 6,050 Total 6,050 Cash and cash equivalents 354 Other tangible assets 470 Liabilities assumed (11,869 ) Goodwill 17,095 Total 6,050 The acquisition above did not have a material impact on the Group’s consolidated financial statements, and, therefore, pro forma disclosures have not been presented. In 2020, the Group acquired 16% equity interest with liquidation preference of a private company (the “Investee”), which primarily provides offline after-school tutoring services, with cash consideration of RMB30.0 million. The investment was accounted for using measurement alternative.

Financial Instruments Fair value The following table sets forth the major financial assets, measured at fair value, by level within the fair value hierarchy as of December 31, 2022 and 2023: Fair value measurements Total Significant other RMB RMB As of December 31, 2022 Short-term investments 232,152 232,152 Total 232,152 232,152 As of December 31, 2023 Short-term investments 71,848 71,848 Total 71,848 71,848 The short-term investments are comprised of investments in wealth management products issued by financial institutions. The Group estimates the fair value of investments in short-term investments using alternative pricing sources and models utilizing market observable inputs, and accordingly the Group classifies the valuation techniques that use these inputs as Level 2. The short-term investments usually have short original maturities of less than 1 year, the carrying value approximates to fair value. During the years ended December 31, 2022 and 2023, gross unrealized gains of RMB957 and RMB848 were recorded in short-term investments, respectively. The financial liabilities mainly comprised of the loans from NetEase Group. The rates of interest under the loan agreements from NetEase Group were determined based on the prevailing interest rates in the market. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements of short-term loans and long-term For other financial assets and liabilities that are not measured at fair value, the carrying values approximate their fair values due to short maturities or the interest rates are close to the market interest rates.

(b) Litigation From time to time, the Group is involved in claims and legal proceedings that arise in the ordinary course of business. Based on currently available information, management does not believe that the ultimate outcome of any unresolved matters, individually and in the aggregate, is reasonably possible to have a material adverse effect on the Group’s financial position, results of operations or cash flows. However, litigation is subject to inherent uncertainties and the Group’s view of these matters may change in the future. The Group records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Group reviews the need for any such liability on a regular basis. The Group has not recorded any material liabilities in this regard as of December 31, 2022 and 2023.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Summary of Significant Accounting Policies [Abstract]
Basis of presentation	(a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below.
Principles of consolidation	(b) Principles of consolidation Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power, 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 the board 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 arrangements, has the power to direct the activities that most significantly impact the entity’s economic performance, bears the risks of and enjoys the rewards normally associated with ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity. All significant intercompany balances and transactions within the Group have been eliminated upon consolidation.
Discontinued operations	(c) Discontinued operations The Group reports a disposal of its component or a group of its components as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on the Group’s operations and financial results. Classification as a discontinued operation occurs upon disposal or when the operation meets the criteria to be classified as held for sale, if earlier. In the period that a discontinued operation is classified as held for sale, the assets and liabilities of the discontinued operation are presents separately in asset and liability sections, respectively, of the consolidated balance sheets and prior periods are presented on a comparative basis. In the consolidated statements of operations and comprehensive loss, the results from discontinued operations are reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinued operations are presented separately in the consolidated statements of cash flows. Unless otherwise noted, discussion in the Notes to consolidated financial statements refers to the Group’s continuing operations. Refer to Note 3 for additional information.
Use of estimates	(d) Use of estimates The preparation of the Group’s consolidated financial statements in conformity with the U.S. GAAP requires management to make estimates and assumptions which affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the balance sheet date and reported revenues and expenses during the reported periods in the consolidated financial statements and accompanying notes. Significant accounting estimates include, but are not limited to, determination of the learning period of the customers, fair value of assets and liabilities acquired in business combinations, allowances for expected credit losses, assessment for impairment of long-lived assets, intangible assets and goodwill, lower of cost and net realizable value of inventories, valuation allowance of deferred tax assets, valuation and recognition of share-based compensation expenses. Actual results could differ from those estimates and such differences may be material to the consolidated financial statements.
Functional currency and foreign currency translation	(e) Functional currency and foreign currency translation The Group uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company is United States dollars (“US$” or “USD”). The functional currency of the Company’s PRC subsidiaries, VIEs, VIEs’ subsidiaries as well as one subsidiary incorporated in Hong Kong is RMB. The determination of the respective functional currencies based on the criteria of ASC 830, Foreign Currency Matters In the consolidated financial statements, the financial information of the Company has been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the period. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. Net gains and losses resulting from foreign exchange transactions are included in others, net in the consolidated statements of operations and comprehensive loss.
Convenience translation	(f) Convenience translation Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into USD as of and for the year ended December 31, 2023 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB 7.0999, representing the exchange rate set forth in the H.10 statistical release of the Federal Reserve Board on December 29, 2023. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into USD at such rate.
Fair value measurements	(g) Fair value measurements Fair value reflects 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 Group applies a fair value hierarchy that 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. Accounting guidance specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation techniques are observable or unobservable. The hierarchy is as follows: Level 1—Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured. Level 2—Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques. Level 3—Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Accounting guidance also describes three main approaches to measure 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. When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. Financial assets and liabilities of the Group primarily consist of cash and cash equivalents, time deposits, restricted cash, short-term investments, accounts receivable, other receivables, amounts due from/to NetEase Group, accounts payables, contract liabilities, accrued liabilities and other payables, short-term loans and long-term loans from NetEase Group of which the carrying values approximate their fair values. Please see Note 18 for additional information.
Cash and cash equivalents	(h) Cash and cash equivalents Cash and cash equivalents consist of cash on hand and demand deposits, which have original maturities less than three months and are readily convertible to known amount of cash.
Time deposits	(i) Time deposits Time deposits represent time deposits placed with banks with original maturities of three months or more than three months but less than one year. Interest earned is recorded as interest income in the consolidated statements of operations and comprehensive loss during the periods presented.
Receivables, net	(j) Receivables, net The Group’s receivables are subject to the measurement of credit losses within the scope of ASC 326. To estimate expected credit losses, the Group has identified the relevant risk characteristics of its customers and the related receivables and other receivables which include size, type of the services or the products the Group provides, or a combination of these characteristics. Receivables with similar risk characteristics have been grouped into pools. For each pool, the Group considers the past collection experience, current economic conditions, future economic conditions (external data and macroeconomic factors) and changes in the Group’s customer collection trends. This is assessed at each quarter based on the Group’s specific facts and circumstances.
Investments	(k) Investments i) Short-term investments Short-term investments include investments in financial instruments with a variable interest rate indexed to performance of underlying assets. In accordance with ASC 825, Financial Instruments, ii) Long-term investments Long-term investments are comprised of equity investments in privately-held companies and limited partnership. For investments in ordinary shares or in-substance in-substance Investments in ordinary shares or in-substance Management regularly evaluates the impairment of the equity investments without readily determinable fair value and equity method investments at each balance sheet date, or more frequently if events or circumstances indicate that the carrying amount may not be recoverable. For investments without readily determinable fair values, management performs a qualitative assessment of impairment indicators. If considered impaired, management estimates the fair value of the investment, and records an impairment in the consolidated statements of operations and comprehensive loss to the extent the carrying amount exceeds the fair value. For equity method investments, management considers if the investment is impaired when events or circumstances suggest the carrying amount may not be recoverable, and recognizes any impairment charge in the consolidated statements of operations and comprehensive loss for a decline in value that is determined to be other than temporary.
Inventories	(l) Inventories Inventories, consisting of smart devices and learning materials for tutoring services, are stated at the lower of cost and net realizable value. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventory to the estimated net realizable value due to slow-moving merchandise and damaged goods, which is dependent upon factors such as historical and forecasted consumer demand, and promotional environment. The Group takes ownership, risks and rewards of the products purchased. Write downs are recorded in cost of revenues in the consolidated statements of operations and comprehensive loss.
Property, equipment and software, net	(m) Property, equipment and software, net Property, equipment and software are stated at cost less accumulated depreciation and impairment, if any. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range as follows: Servers and computers 3-5 Furniture, fixtures, office and other equipment 3-5 Leasehold improvements The shorter of the useful life or term of the lease Software and others 3-5 Expenditures for maintenance and repairs are expensed as incurred. The gain or loss on the disposal of property, equipment and software is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of operations and comprehensive loss.
Goodwill	(n) Goodwill Goodwill represents the excess of the purchase consideration over the fair value of the identifiable assets acquired and the liabilities assumed Goodwill is not amortized but is tested for impairment at the reporting unit level on an annual basis by the end of year, and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Under ASC 350-20-35, Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit.
Impairment of long-lived assets	(o) Impairment of long-lived assets Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will affect the future use of the assets) indicate that the carrying value of an asset may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment for the long-lived assets by comparing the carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. The Group recognized impairment losses on intangible assets from business combination of RMB56,778, nil, and nil for the years ended December 31, 2021, 2022 and 2023, respectively.
Revenue recognition	(p) Revenue recognition The Group adopted ASC 606, Revenue from Contracts with Customers Disaggregation of net revenues For the years ended December 31, 2021, 2022 and 2023, substantially all of the Group’s net revenues were generated in the PRC. The following table provides information about disaggregated revenue by types: For the year ended December 31, 2021 2022 2023 RMB RMB RMB Learning services 2,441,421 3,084,375 3,148,114 Tutoring services 2,271,036 2,886,126 2,914,064 Fee-based 170,385 198,249 234,050 Smart devices 980,424 1,256,446 909,192 Online marketing services 593,949 672,361 1,331,902 Total net revenues 4,015,794 5,013,182 5,389,208 i) Learning services Tutoring services The Group offers various types of integrated learning services, which primarily cover a wide spectrum of topics and target people from broad age groups through its diverse offerings of tutoring courses and digital learning contents, foreign languages, professional and interest education services as well as IT computer skills, etc. The Group’s tutoring courses consist of online live streaming and other activities during the online live streaming period including teaching material, quiz banks, online chat rooms, summary of lessons after each class and interactions with both students and instructors. Once the online live streaming is completed, the Group also offers the customer a content playback service. With respect to the content playback service, the customer has unlimited access to previous online live streaming courses for a specified period. The services of online live streaming, playback service, as well as the other activities provided mentioned above are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming courses and therefore are not distinct and are not sold standalone. Therefore, the Group’s tutoring courses are accounted for as a single performance obligation. This performance obligation is satisfied over the learning period of the customers. Accordingly, the Group recognizes the revenues ratably over the estimated average learning period for different courses. The Group considers the average period that customers typically spend time on the courses and other learning behavior patterns to arrive at the best estimate for the estimated learning period for each course based on the estimated learning time customers spend on the courses, the expected number of times customers will take the courses and the similarities between newly-launched The Group’s tutoring courses also consist of online pre-recorded The Group also offers digital learning contents to customers which are delivered together with online live streaming courses and customized planning services. The customers can either stream the digital learning contents online or download and watch them offline. The downloadable digital learning contents, streaming services, online live streaming courses and customized planning services are considered as distinct performance obligations in the contract. The transaction price is generally collected in advance and allocated to each performance obligation in the contract based on the relative standalone selling prices. The Group recognizes the revenues of downloadable digital learning contents as the performance obligation is satisfied upon the time of delivery. The revenues of streaming services and customized planning services are recognized ratably over the service period. For online live streaming courses, the revenues are recognized ratably over the estimated average learning period. The estimated weighted average duration of learning periods is approximately ranged from five to six months for the years ended December 31, 2021, 2022 and 2023 for both online live streaming courses and online pre-recorded There is a refund policy provided to customers for tutoring services, depending on whether the course had commenced at the time of the refund request, the length of the course, the number of sessions that the T he Group determines the transaction price to be earned by estimating the refund liabilities based on historical refund ratio on a portfolio basis using the expected value method. The Group also provides discount coupons to its customers for use in purchases on tutoring services, which are treated as a reduction of revenue when the related transaction is recognized. Fee-based Fee-based Youdao Dictionary Youdao Smart Cloud ii) Smart devices The Group sells smart devices such as Youdao Dictionary Pen, Youdao Listening Pod Youdao Smart Learning Pad Along with certain learning services, the Group also provides devices such as Youdao Smart Learning Terminal iii) Online marketing services The Group derives its online marketing revenues principally from short-term contracts. The online marketing services with display period, the contracts may consist of multiple performance obligations with a typical term of less than three months. Each performance obligation generally represents different formats of advertisement, including but not limited to banners, text-links, videos, logos, buttons and rich media. In arrangements where the Group has multiple performance obligations, the transaction price is allocated to each performance obligation using the relative stand-alone selling price. The Group generally determines stand-alone selling prices based on the prices charged to customers. If the performance obligation has not been sold separately, the Group estimates the stand-alone selling price by taking into consideration of the pricing for advertising areas of the Group’s platform with a similar popularities and advertisements with similar formats and quoted prices from competitors as well as other market conditions. Considerations allocated to each performance obligation is recognized as revenue over the individual advertisement display period, on a straight-line basis, which is usually within three months. The Group also enters into cost-per-click The Group’s online marketing services expand distribution of advertisers’ promotional links and advertisements by leveraging traffic on third parties’ internet properties, including web content, software, and mobile applications. The Group is the primary obligor to its advertisers as it is primarily responsible to the customers, bears inventory risk and has the discretion in establishing pricing. Payments made to operators of third-party internet properties are included in the traffic acquisition costs. Certain customers may receive volume rebates, which are accounted for as variable consideration. The Group estimates annual expected revenue volume with reference to their historical results and reduce revenues recognized. Practical expedients The Group has used the following practical expedients as allowed under ASC 606: (i) The effects of a significant financing component have not been adjusted for contracts which the Group expects, at contract inception, that the period between when the Group transfers a promised good or service to the customer and when the customer pays for that good or service will be one year or less. (ii) The Group applied the portfolio approach in determining the learning period of the customers given that the effect of applying a portfolio approach to a group of students’ behaviors would not differ materially from considering each one of them individually. Contract balances Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represent amounts invoiced and revenue recognized prior to invoicing, when the Group has satisfied its performance obligations and has the unconditional right to payment. Contract liabilities Contract liabilities refer to the deferred revenue and refund liabilities. Deferred revenue is relating to the learning tuition, online marketing services and fee-based premium services with fees received from customers for which the Group’s revenue recognition criteria have not been met. Revenue recognized that was included in the deferred revenue balance at January 1, 2022 and January 1, 2023 amounted to RMB941,246 and RMB987,533, respectively. As of December 31, 2023, the aggregate amount of transaction price allocated to unsatisfied performance obligations is RMB1,025.2 million which includes deferred revenue balances and amounts to be invoiced and recognized as revenue in future periods. The Group expects to recognize RMB1,008.9 million as revenue over the next 12 months. This balance does not include an estimate for variable consideration arising from sales rebates to advertising service customers. Refund liabilities represent the consideration collected by the Group which it expects to refund to its customers according to refund policy. Refund liabilities are estimated based on the historical refund ratio for each of the revenue streams. The refund liabilities were not material, as of December 31, 2022 and 2023. In the event that the actual amount of refund made exceeds the estimation, such excessive amount will be deducted from net revenues.
Cost of revenues	(q) Cost of revenues Cost of revenues primarily consists of the revenue sharing and payroll expenses to instructors and tutors, traffic acquisition costs, content costs, servers and bandwidth service fees and other direct costs of providing these services as well as costs of smart devices sold.
Sales and marketing expenses	(r) Sales and marketing expenses Sales and marketing expenses mainly consist of marketing and promotional expenses, payroll related expenses and third-party service fee for outsourced sales and marketing functions. The Group expenses all advertising costs as incurred and classifies these costs under sales and marketing expenses. For the years ended December 31, 2021, 2022 and 2023, advertising expenses were RMB1,393.3 million, RMB1,479.0 million and RMB1,384.3 million, respectively.
Research and development expenses	(s) Research and development expenses Research and development expenses mainly consist of personnel related expenses and technology service costs incurred for the learning courses and its development, as well as development and enhancement of the Group’s websites and applications platforms. For internal use software, the Group expenses all costs incurred for the preliminary project stage and post implementation-operation stage of development, and costs associated with repair or maintenance of the existing platforms. Costs incurred in the application development stage are capitalized and amortized over the estimated useful life. Since the amount of the Group’s research and development expenses qualifying for capitalization has been immaterial, as a result, all development costs incurred for development of internal used software have been expensed as incurred. For external use software, costs incurred for development of external use software have not been capitalized since the inception of the Group, because the period after the date technical feasibility is reached and the time when the software is marketed is short historically, and the amount of costs qualifying for capitalization has been immaterial. No costs incurred for development of learning content, products and advertising services have been capitalized because the period after the date technical feasibility is reached and the time when relevant products and services are marketed is historically short.
Share-based compensation	(t) Share-based compensation The Group grants options and restricted share units, or RSUs to its employees, directors and consultants with performance conditions and service conditions. In accordance with ASC 718, Compensation-Stock Compensation The Group adopts the binomial option pricing model to determine the fair value of share options. The determination of the fair value of share options is affected by the fair value of ordinary shares as well as assumptions regarding a number of complex and subjective variables, including the expected share price volatility, actual and projected employee share option exercise behavior, risk free interest rates and expected dividends. Upon the completion of the IPO, the market price of the Company’s publicly traded ADSs is used as an indicator of fair value of ordinary shares for purposes of recording share-based compensation expenses. RSUs are measured based on the fair market value of the underlying ordinary shares on the dates of grant. Share-based compensation expenses for share options and RSUs granted with service conditions are recorded net of estimated forfeitures using graded-vesting method over the requisite service period, such that expenses are recorded only for those share-based awards that are expected to ultimately vest. The Group also recognizes compensation expenses on RSUs, granted by the Parent to the employees of the Group. RSUs are measured based on the fair market value of the underlying ordinary shares on the dates of grant. Share-based compensation expenses related are then recorded for the number of RSUs expected to vest on a graded-vesting basis, net of estimated forfeitures, over the requisite service period.
Employee benefits	(u) Employee benefits PRC Contribution Plan Full-time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to the employees. Chinese labor regulations require that the PRC subsidiaries and the VIEs of the Group make contributions to the government for these benefits based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts of such employee benefit expenses, which were expensed as incurred, were approximately RMB222,690, RMB322,168 and RMB321,025 for the years ended December 31, 2021, 2022 and 2023, respectively.
Taxation	(v) Taxation Income taxes Current income taxes are provided on the basis of income/(loss) 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 provided using the 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 purposes. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of operations and comprehensive loss 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 In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step two-step 50
Business combinations	(w) Business combinations The Group accounts for its business combination using the acquisition method of accounting in accordance with ASC 805, Business Combinations If a business combination is under common control, the acquired assets and liabilities are recognized at their historical book value. The consolidated financial statements include the results of the acquired entities from the earliest date presented or, if more recent, from the date when the entities first came under common control, regardless of the date of the combination. Consolidated financial statements for prior years would also be retrospectively adjusted for periods during which the entities were under common control. In a business combination achieved in stages, the Company remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons.
Operating leases	(x) Operating leases The Group has operating leases primarily for office space. The determination of whether an arrangement is a lease or contains a lease is made at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Group obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. The Group elects not to recognize lease liabilities and associated right-of-use right-of-use The Group uses the implicit rate when readily determinable, or its incremental borrowing rate based on the information available, at the commencement date in determining the present value of lease payments. Certain leases include renewal options and/or termination options. Renewal options are included in the lease term if the Group is reasonably certain to exercise those options while options to terminate the lease are only included in the lease term if the Group is reasonably certain not to exercise those options. Lease expenses are recorded on a straight-line basis over the lease term.
Related parties	(y) 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.
Noncontrolling interests and Redeemable noncontrolling interests	(z) Noncontrolling interests and Redeemable noncontrolling interests For the Company’s majority-owned subsidiaries and VIEs, noncontrolling interests are recognized to reflect the portion of their equity that are not attributable, directly or indirectly, to the Company as the controlling shareholders. The noncontrolling interest will continue to be attributed with its share of losses even if that attribution results in a deficit noncontrolling interest balance. Redeemable noncontrolling interests represent redeemable equity interests issued by a VIE’s subsidiary of the Group to certain noncontrolling shareholders (Note 5), and have been classified as mezzanine classified noncontrolling interests in the consolidated financial statements as these interests are contingently redeemable upon the occurrence of certain conditional events, which is not solely within the control of the Group. The redeemable equity interests will automatically be forfeited upon the conditional events not occur in the agreed period. The accretion of the redeemable equity interests would be recognized when the redemption value is over the balance of noncontrolling interests.
Net loss per share	(aa) Net loss per share Net loss per share is computed in accordance with ASC 260, Earnings per Share
Statutory reserves	(bb) Statutory reserves The Company’s subsidiaries and VIEs established in the PRC are required to make appropriations to certain non-distributable after-tax non-distributable after-tax Pursuant to the laws applicable to China’s Foreign Investment Enterprises, the Company’s subsidiaries registered as majority-owned or wholly-owned foreign investment enterprise (“FIE”) in China make appropriations from their annual after-tax after-tax
Comprehensive loss	(cc) Comprehensive loss Comprehensive loss is defined to include all changes in equity deficit of the Group during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Comprehensive loss includes net loss and foreign currency translation adjustment of the Group.
Segment reporting	(dd) Segment reporting In accordance with ASC 280, Segment Reporting The Group currently does not allocate operating expenses or assets to its segments, as its CODM does not use such information to allocate resources or evaluate the performance of the operating segments. As the Group’s long-lived assets are substantially all located in the PRC and the Group’s revenues are substantially derived from the PRC, no geographical segments are presented.
