Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Reorganization	1. Organization and Reorganization TuanChe Limited (the “Company”) was incorporated in the Cayman Islands on September 28, 2012. The Company is a holding company and conducts its business mainly through its subsidiaries, variable interest entities ("VIEs") and subsidiaries of VIEs (collectively referred to as the "Group"). The Group is primarily engaged in the operation of providing auto shows, group-purchase facilitation and electric vehicle sales facilitation in the People’s Republic of China (the "PRC" or "China"). The Group commenced its auto shows business from fourth quarter of 2016. The Group decided to discontinue the electric vehicle sales facilitation business in December 2017. In 2018, the Group commenced its virtual dealership business and demand-side platform advertising business. As of December 31, 2018, the Company's subsidiaries, major VIEs and major subsidiaries of VIEs are as follows: Subsidiaries Place and year of incorporation Percentage of direct or indirect Principal activities TuanChe Information Limited (“TuanChe Information”) Hong Kong, PRC 2012 100 Investment holding TuanYuan Internet Technology (Beijing) Co., Ltd.

(“Tianjin Hengyuan”) Tianjin, PRC 2016 100 Vehicle sales facilitation * On June 22, 2018, Zhongrui Guochuang was restructured from being a VIE of TuanYuan to a subsidiary of TuanChe Internet. History of the Group Reorganization The Group commenced operations through TuanChe Internet, a PRC company established by several PRC citizens in May 2012. TuanChe Internet holds an Internet Content Provider (“ICP”) license to operate Tuanche.com that provides internet information services to automobile manufacturers, car dealers and consumers. The Company was incorporated in the Cayman Islands in September 2012. The Company established TuanYuan in January 2013 to control TuanChe Internet through contractual arrangements and TuanChe Internet became a VIE of the Group (the “Reorganization”). These arrangements were accounted for as a reorganization and the historical financial statements were presented on a carryover basis. Discontinued operations On December 10, 2017, pursuant to the resolution of the shareholders and board of directors of the Company, management decided to discontinue its electric vehicle sales facilitation business (the “Discontinued Business”). The Discontinued Business represents a strategic shift that has a major effect on the Company’s operations and financial results. Refer to Note 3 for details of discontinued operations. Initial Public Offering On November 20, 2018, the Company completed its initial public offering (“IPO”) on the NASDAQ Global Market in the United States of America. In this offering, 2,600,000 American Depositary Shares (“ADSs”), representing 10,400,000 Class A ordinary shares, were issued and sold to the public at a price of US$7.80 per ADS. The net proceeds to the Company from the IPO, after deducting commissions and offering expenses, were approximately US$15.0 million (RMB103.4 million). Contractual arrangements with VIEs PRC laws and regulations place certain restrictions on foreign investment in value-added telecommunication service businesses. The Company conducts a portion of their operations in the PRC through TuanChe Internet, and its subsidiaries. The Company has effective control over its VIEs and subsidiaries of VIEs through a series of contractual arrangements among its wholly-owned PRC subsidiary TuanYuan, VIEs and their shareholders. The contractual arrangements, as described in more detail below, collectively allow the Company to: • exercise effective control over each of its VIEs and subsidiaries of VIEs; • receive substantially all of the economic benefits of VIEs and subsidiaries of VIEs; and • have an exclusive call option to purchase all or part of the equity interests in and/or assets of each of VIEs and subsidiaries of VIEs when and to the extent permitted by PRC laws. As a result of these contractual arrangements, the Company is the primary beneficiary of VIEs and subsidiaries of VIEs, and, therefore, have consolidated the financial results of VIEs and subsidiaries of VIEs in its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Below is a summary of the currently effective contractual arrangements by and among the Company’s wholly-owned subsidiary TuanYuan, TuanChe Internet and its shareholders. Exclusive Management Services and Business Cooperation Agreement Pursuant to the exclusive management services and business cooperation agreement among TuanYuan, TuanChe Internet and its shareholders, TuanYuan has the exclusive right to provide or designate any third party to provide, among other things, transfer of technology, technology development services, online advertising services, consulting services, technological support and business support to TuanChe Internet and its subsidiaries. In exchange, TuanChe Internet and its subsidiaries pay service fees to TuanYuan in an amount at TuanYuan’s discretion. Without the prior written consent of TuanYuan, TuanChe Internet and its subsidiaries cannot accept services provided by or establish similar cooperation relationship with any third party. TuanYuan owns the exclusive intellectual property rights created as a result of the performance of this agreement unless otherwise provided by PRC laws or regulations. This agreement was entered into on March 6, 2013 and became effective on March 6, 2013 and will remain effective unless unanimously agreed by the parties concerned or unilaterally terminated by TuanYuan with a written notice. Unless otherwise required by applicable PRC laws, TuanChe Internet and its shareholders do not have any right to terminate the exclusive service agreement. Exclusive Call Option Agreement Under the exclusive call option agreement among TuanYuan, TuanChe Internet and its shareholders, each of the shareholders of TuanChe Internet irrevocably granted TuanYuan a right to purchase, or designate a third party to purchase, all or any part of their equity interests in TuanChe Internet at a purchase price equal to the lowest price permissible by the then-applicable PRC laws and regulations at TuanYuan’s sole and absolute discretion to the extent permitted by PRC law. The shareholders of TuanChe Internet shall promptly give all considerations they received from the exercise of the options to TuanYuan or a designated third party of TuanYuan. Without TuanYuan’s prior written consent, TuanChe Internet and its shareholders shall not enter into any major contract to transfer any equity of TuanChe Internet. Without TuanYuan’s prior written consent, TuanChe Internet and its shareholders shall not sell, transfer, license or otherwise dispose of any TuanChe Internet’s assets or allow any encumbrance of any assets, except for the disposal or the encumbrances of the assets that are treated as necessary for their daily business operations with the value of the assets involved in a single transaction not exceeding RMB100,000. TuanChe Internet shall not be dissolved or liquidated without the written consent by TuanYuan. This agreement was entered into on March 6, 2013 and became effective on March 6, 2013 and shall remain in effect upon expiry or early termination of this agreement. Equity Pledge Agreement Under the Equity Pledge Agreement among TuanYuan, TuanChe Internet and its shareholders, TuanChe Internet’s shareholders pledged all of their equity of TuanChe Internet to TuanYuan as security for performance of the obligations of TuanChe Internet and its shareholders under the exclusive call option agreement, the exclusive management services and business cooperation agreement and the powers of attorney. If any of the specified events of default occurs, TuanYuan may exercise the right to enforce the pledge immediately. TuanYuan may transfer all or any of its rights and obligations under the Equity Pledge Agreement to its designee(s) at any time. The equity pledge agreement is binding on TuanChe Internet’s shareholders and their successors. This agreement was enterred into on March 6, 2013 and became effective on March 6, 2013, and shall remain in effect until the fulfillment of all the obligations under the Exclusive Call Option Agreement, the Exclusive Management Services and Business Cooperation Agreement and the Powers of Attorney. Powers of Attorney Pursuant to the Powers of Attorney executed by TuanChe Internet and its shareholders, each of them irrevocably authorized TuanYuan to act on their respective behalf as exclusive agent and attorney, to the extent permitted by law, with respect to all rights of shareholders concerning all the equity interest and sponsor interest held by each of them in TuanChe Internet or its subsidiaries, including but not limited to proposing to convene or attend shareholder meetings, board meetings or council meetings, signing the resolutions and minutes of such meetings, exercising all the rights as shareholders or sponsors (including but not limited to voting rights, nomination rights, appointment rights, the right to receive dividends and the right to sell, transfer, pledge or dispose of all the equity or the sponsor interest held in part or in whole). This agreement was entered into on March 6, 2013 and became effective on March 6, 2013. In August 2014, June 2017 and August 2017, the Exclusive Management Services and Business Cooperation Agreement, Exclusive Call Option Agreement, Equity Pledge Agreement and Powers of Attorney to TuanChe Internet were amended to reflect the changes of shareholders’ holding in the VIE entity. No other material terms or conditions of these agreements were changed or altered. There was no impact to the Group’s effective control over TuanChe Internet and the Group continues to consolidate TuanChe Internet. Zhongrui Guochuang was incorporated in 2016 to carry out similar business as TuanChe Internet. The Company has effective control over Zhongrui Guochuang through a series of contractual arrangements having similar terms with that of the contractual arrangements with TuanChe Internet among TuanYuan, Zhongrui Guochuang and its shareholders (also nominee shareholders). As a result of these contractual arrangements with Zhongrui Guochuang , the Company is the primary beneficiary of Zhongrui Guochuang, and, therefore, consolidated the financial results of Zhongrui Guochuang in its consolidated financial statements in accordance with U.S. GAAP. On June 22, 2018, Zhongrui Guochuang was restructured from being a VIE of TuanYuan to a subsidiary of TuanChe Internet. Risks in relation to the VIE structure In May 2018, Best Cars Limited (“Best Cars”), a British Virgin Islands (“BVI”) incorporated company and a consolidated variable interest entity of the Group, was established by its shareholders to facilitate the adoption of the Company’s employee stock incentive plans. The Company entered into a agreement with Best Cars and its shareholder in which provides the Company with effective control over Best Cars and enables the Company to obtain substantially all of the economic benefits arising from Best Cars. As of December 31, 2018, Best Cars held 38,723,321 Class A ordinary shares of the Company. A significant part of the Company's business is conducted through the VIEs of the Group, of which the Company is the ultimate primary beneficiary. In the opinion of management, the contractual arrangements with the VIEs and the nominee shareholders are in compliance with PRC laws and regulations and are legally binding and enforceable. The nominee shareholders are also shareholders of the Group and have indicated they will not act contrary to the contractual arrangements. However, there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations including those that govern the contractual arrangements, which could limit the Group's ability to enforce these contractual arrangements and if the nominee shareholders of the VIEs were to reduce their interests in the Group, their interest may diverge from that of the Group and that may potentially increase the risk that they would seek to act contrary to the contractual arrangements. In January 2015, the Ministry of Commerce ("MOFCOM"), released for public comment a proposed PRC law, the Draft Foreign Investment Enterprises ("FIE") Law, that appears to include VIEs within the scope of entities that could be considered to be FIEs, that would be subject to restrictions under existing PRC law on foreign investment in certain categories of industry. Specifically, the Draft FIE Law introduces the concept of "actual control" for determining whether an entity is considered to be an FIE. In addition to control through direct or indirect ownership or equity, the Draft FIE Law includes control through contractual arrangements within the definition of "actual control". If the Draft FIE Law is passed by the People's Congress of the PRC and goes into effect in its current form, these provisions regarding control through contractual arrangements could be construed to include the Group's contractual arrangements with its VIEs, and as a result, the Group's VIEs could become explicitly subject to the current restrictions on foreign investment in certain categories of industry. The Draft FIE Law includes provisions that would exempt from the definition of FIEs where the ultimate controlling shareholders are either entities organized under PRC law or individuals who are PRC citizens. The Draft FIE Law is silent as to what type of enforcement action might be taken against existing VIEs, that operates in restricted or prohibited industries and is not controlled by entities organized under PRC law or individuals who are PRC citizens. If the restrictions and prohibitions on FIEs included in the Draft FIE Law are enacted and enforced in their current form, the Group's ability to use the contractual arrangements with its VIEs and the Group's ability to conduct business through the VIEs could be severely limited. The Company's ability to control the VIEs also depends on the Power of Attorney the shareholders has to vote on all matters requiring shareholder approval in the VIEs. As noted above, the Company believes these Power of Attorney are legally enforceable but may not be as effective as direct equity ownership. In addition, if the Group's corporate structure or the contractual arrangements with the VIEs were found to be in violation of any existing or future PRC laws and regulations, the PRC regulatory authorities could, within their respective jurisdictions: • revoke the Group's business and operating licenses; • require the Group to discontinue or restrict its operations; • restrict the Group's right to collect revenues; • block the Group's websites; • require the Group to restructure the operations, re-apply for the necessary licenses or relocate the Group's businesses, staff and assets; • 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 the Group's business. The imposition of any of these restrictions or actions could result in a material adverse effect on the Group's ability to conduct its business. In such case, the Group may not be able to operate or control the VIEs, which may result in deconsolidation of the VIEs in the Group's consolidated financial statements. In the opinion of the Company’s management, the likelihood for the Group to lose such ability is remote based on current facts and circumstances. The Group believes that the contractual arrangements among each of the VIEs, their respective shareholders and relevant wholly foreign owned enterprise are in compliance with PRC law and are legally enforceable. The Group's operations depend on the VIEs to honor their contractual arrangements with the Group. These contractual arrangements are governed by PRC law and disputes arising out of these agreements are expected to be decided by arbitration in the PRC. Management believes that each of the contractual arrangements constitutes valid and legally binding obligations of each party to such contractual arrangements under PRC laws. However, the interpretation and implementation of the laws and regulations in the PRC and their application on the legality, binding effect and enforceability of contracts are subject to the discretion of competent PRC authorities, and therefore there is no assurance that relevant PRC authorities will take the same position as the Group herein in respect of the legality, binding effect and enforceability of each of the contractual arrangements. Meanwhile, since the PRC legal system continues to evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit legal protections available to the Group to enforce the contractual arrangements should the VIEs or the nominee shareholders of the VIEs fail to perform their obligations under those arrangements. The following combined financial information of the Group's VIEs as of December 31, 2017 and 2018 and for the years ended December 31, 2016, 2017 and 2018 were included in the accompanying consolidated financial statements of the Group as follows: As of December 31, As of December 31, 2017 2018 RMB RMB ASSETS Current assets: Cash and cash equivalents 32,210 25,166 Accounts receivable, net 8,467 27,160 Prepayments and other current assets 14,458 16,692 Receivables due from related parties 2,260 - Amount due from the subsidiaries of the Group 1,923 4,973 Held-for-sale assets 837 - Short-term investments 4,000 - Total current assets 64,155 73,991 Non-current assets: Property, equipment and software, net 938 522 Long-term investments 1,000 4,390 Total non-current assets 1,938 4,912 TOTAL ASSETS 66,093 78,903 Current liabilities: Accounts payable 3,340 1,871 Advance from customers 9,751 13,922 Short-term borrowings 24,971 - Salary and welfare benefits payable 40,803 30,535 Other taxes payable 21,476 12,651 Other current liabilities 26,422 5,306 Amount due to the subsidiaries of the Group 182,033 233,295 Total current liabilities 308,796 297,580 Non-current liabilities: Long-term borrowings 2,932 - Total non-current liabilities 2,932 - TOTAL LIABILITIES 311,728 297,580 For the year ended December 31, December 31, December 31, 2016 2017 2018 RMB RMB RMB Net revenues 117,211 280,081 329,788 Net loss from continuing operations (69,138 ) (66,300 ) (34,674 ) Net loss from discontinued operations (5,060 ) (14,977 ) (3,612 ) Net loss (74,198 ) (81,277 ) (38,286 ) For the year ended December 31, December 31, December 31, 2016 2017 2018 RMB RMB RMB Net cash generated from/(used in) operating activities 12,930 (10,540 ) 24,144 Net cash generated from/(used in) investing activities 14,965 - (50 ) Net cash (used in)/ generated from financing activities (12,283 ) 18,148 (31,138 ) Net increase/(decrease) in cash and cash equivalent 15,612 7,608 (7,044 ) In accordance with various contractual agreements, the Company has the power to direct the activities of the VIEs and subsidiaries of VIEs and can have assets transferred out of the VIEs. Therefore, the Company considers that there are no assets in the respective VIEs that can be used only to settle obligations of the respective VIEs, except for the registered capital of the VIEs amounting to approximately RMB10.0 million and RMB10.0 million, as of December 31, 2017 and 2018. As the respective VIEs are incorporated as limited liability companies under the PRC Company Law, creditors do not have recourse to the general credit of the Company for the liabilities of the respective VIEs. There is currently no contractual arrangement that would require the Company to provide additional financial support to the VIEs. As the Group is conducting certain businesses in the PRC through the VIEs, the Group may provide additional financial support on a discretionary basis in the future, which could expose the Group to a loss. There is no VIE in the Group where the Company or any subsidiary has a variable interest but is not the primary beneficiary. Liquidity The Group incurred net losses of RMB86.6 million, RMB90.7 million and RMB78.7 million for the years ended December 31, 2016, 2017 and 2018, respectively. Net cash used in operating activities was RMB54.1 million, RMB59.7 million and RMB53.3 million for the years ended December 31, 2016, 2017 and 2018, respectively. Accumulated deficit was RMB389.3 million and RMB468.0 million as of December 31, 2017 and 2018, respectively. The Group assesses its liquidity by its ability to generate cash from operating activities and attract investors' investments. Historically, the Group has relied principally on both operational sources of cash and non-operational sources of financing from 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. The Group has been continuously receiving financing support from outside investors through the issuance of preferred shares and convertible loans. Refer to Note 13 and 12 for details of the Group’s preferred shares and convertible loans financing activities. Moreover, on July 27 and August 3, 2018, the Group entered into Series D-2 preferred shares purchase agreements with Beijing Z-Park Fund Investment Center (Limited Partner) (“Beijing Z-Park Fund”) and Beijing Shengjing Fengtai Innovation Investment Center (Limited Partner) (“Beijing Shengjing Fengtai Innovation”) whereby Beijing Z-Park Fund and Beijing Shengjing Fengtai Innovation will acquire 20,630,925 and 949,023 Series D-2 preferred shares for US$50 million and US$2.3 million, respectively. On September 28, 2018, the Company has received US$50 million from Beijing Z-park Fund. On November 20, 2018, the Company completed its initial public offering (“IPO”) on the NASDAQ Global Market in the United States of America. The net proceeds to the Company from the IPO, after deducting commissions and offering expenses, were approximately US$15.0 million (RMB103.4 million). The Group also can adjust the pace of its operation expansion and control the operating expenses of the Group. Based on the above considerations, the Group believes the cash and cash equivalents currently on hand are sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months from the date of the issurance of the consolidated financial statements. 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.

Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with 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 The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIEs and subsidiaries of VIEs for which the Company is the primary beneficiary. 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 transactions and balances among the Company, its subsidiaries, VIEs and subsidiaries of VIEs have been eliminated upon consolidation. c) Discontinued operations A component of a reporting entity or a group of components of a reporting entity that are disposed or meet the criteria to be classified as held for sale, such as the management, having the authority to approve the action, commits to a plan to sell the disposal group, should be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Discontinued operations are reported when a component of an entity comprising operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the entity is classified as held for disposal or has been disposed of, if the component either (1) represents a strategic shift or (2) have a major impact on an entity’s financial results and operations. In the consolidated statements of operations and comprehensive loss, result from discontinued operations is reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinuing operations are presented separately in Note 3. In order to present the financial effects of the continuing operations and discontinued operations, revenues and expenses arising from intra-group transactions are eliminated except for those revenues and expenses that are considered to continue after the disposal of the discontinued operations. Inventories comprise electric vehicles on display at show rooms. Inventories are valued at the lower of cost or net realizable value. Cost of inventories is determined by the weighted-average method. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. The Group continually evaluates the recoverability based on assumptions about future customer demand and market conditions. The evaluation may take into consideration inventory aging, expected demand, anticipated sales price, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future customer demand and market conditions. As of December 31, 2017 and 2018, there was no write-down of inventories. Non-current assets or disposal groups are classified as assets held for sale when the carrying amount is to be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such asset. The Group purchases cars on behalf of consumers from auto makers and auto dealers. As the Group is not primarily responsible for the acceptability of the electric vehicles and does not assume inventory risk of the cars, it is considered to be an agent in accordance with ASC 606. Commission income upon each successful sale is recognized at a point in time following the transfer of control of cars. As of December 31, 2017, the prepayments and other current assets, inventories, property, equipment and software and other current liabilities related to the Discontinued Business are classified as “Held-for-sale” in the consolidated financial statements of the Group. On June 30, 2018, the Company completed the disposal of the Discontinued Business. 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 that 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, assessment for valuation allowance of deferred tax assets, determination of the fair value of ordinary shares, preferred shares and warrant, and valuation and recognition of share-based compensation expenses. e) Functional currency and foreign currency translation The Group uses Renminbi ("RMB") as its reporting currency. The functional currency of the Company and its overseas subsidiaries which incorporated in the Cayman Islands and Hong Kong is United States dollars ("US$"). The functional currency of the Group's PRC entities is RMB. In the consolidated financial statements, the financial information of the Company and other entities located outside of the PRC have been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, and expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. Net gains and losses resulting from foreign exchange transactions are included in exchange (losses)/gains in the consolidated statements of operations and comprehensive loss. f) Convenience Translation Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2018 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.8755, representing the the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2018. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2018, or at any other rate. g) Fair value measurements Accounting guidance defines fair value as 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. Accounting guidance establishes 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 establishes three levels of inputs that may be used to measure fair value: · Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. · Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical asset or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. · Level 3 applies to asset or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the The Group's financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, other receivables, accounts payable, short-term borrowings and other payables, of which the carrying values approximate their fair value. See Note 20 for additional information. h) Cash, cash equivalents and restricted cash Cash and cash equivalents mainly represent cash on hand, demand deposits placed with large reputable banks in the United States of America or China, and highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase with terms of three months or less. As of December 31, 2017 and 2018, there were cash at bank and demand deposits with terms of less than three months denominated in US dollars amounting to approximately US$5.3 million and US$73.5 million, respectively (equivalent to approximately RMB34.4 million and RMB504.2 million, respectively). As of December 31, 2017 and 2018, the Group had approximately RMB32.2 million and RMB74.4 million cash and cash equivalents held by its PRC subsidiaries, VIEs and subsidiaries of VIEs, representing 48.3% and 12.9% of total cash and cash equivalents of the Group, respectively. As of December 31, 2017 and 2018, the Company had a restricted cash balance approximately RMB11.1 million and nil, respectively, which is a deposit in bank and held as collateral for the Group’s VIE’s short-term borrowing. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash. Therefore, amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. The Company early adopted the amendments in fiscal year 2016. The changes in restricted cash in the consolidated statements of cash flows were RMB11.1 million and RMB(11.1) million for the years ended December 31, 2017 and 2018, respectively. i) Accounts receivable, net The carrying value of accounts receivable is reduced by an allowance that reflects the Group’s best estimate of the amounts that will not be collected. Many factors are considered in estimating the general allowance, including but not limited to reviewing accounts receivable balances, historical bad debt rates, aging analysis, customer credit worthiness and industry trend analysis. The Group also makes the specific allowance if there is evidence showing that the receivable is unlikely to be collected. Accounts receivable balances are written off against the allowance when they are determined to be uncollectible. Refer to Note 4 for details. j) Short-term investments Short-term investments mainly comprised of wealth management products, highly liquid investments placed with banks with original maturities longer than three months but within one year, and interest generating loan provided to a third party. As of December 31, 2017 and 2018, the interest generating loan provided to a third party of the Group was RMB4.0 million and nil, respectively. The interest generating loan provided to a third party was fully collected on July 3, 2018. k) 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 following estimated useful lives: Furniture and electronic equipment 3 years Vehicles 10 years Software 5 years Leasehold improvements Shorter of expected lives of leasehold improvements and lease term 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. l) Assets and liabilities held-for-sale Assets and liabilities to be sold shall be classified as held-for-sale considering the recognition criteria in which all of the following criteria are met: · Management, having the authority to approve the action, commits to a plan to sell the assets and liabilities. · The assets and liabilities are available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets. · An active program to locate a buyer and other actions required to complete the plan for the sale has been initiated. · The sale is probable, and transfer of the asset is expected to qualify for recognition as a completed sale, within one year, · The assets and liabilities are being actively marketed for sale at a price that is reasonable in relation to its current fair value. · Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. m) 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 impact 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. No impairment charge was recognized for any of the periods presented. n) Long-term investments In accordance with ASC 325 Investment—Other, for investments in equity instruments which the Company does not have significant influence, and whose fair value is not readily determinable, the cost method accounting is applied. Gain or losses are realized when such investment is sold or when dividends are declared or payments are received. The Company assesses its equity investments for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, the operating performance of the companies including current earnings trends, and other company-specific information such as financing rounds. Investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC topic 323 Investments-Equity Method and Joint Ventures. The Company adjusts the carrying amount of equity method investment for its share of the income or losses of the investee and reports the recognized income or losses in the consolidated statements of operations and comprehensive loss. The Company’s share of the income or losses of an investee are based on the shares of common stock and in-substance common stock held by the Company. o) Other non-current assets As of December 31, 2018, other non-current assets comprises mainly prepayments for the purchases of softwares. p) Warrant On October 31, 2017, a warrant to purchase Series C-2 convertible redeemable preferred shares of the Company was issued in connection with the debt financing and is classified as a liability and is treated as upfront issuance costs based on the estimated fair value of the warrant at issuance date. Subsequently, changes in the fair value of the warrant for Series C-2 convertible redeemable preferred shares is recorded in the consolidated statements of operations and comprehensive loss. The upfront issuance costs are amortized over the term of the debt financing. As of December 31, 2017 and 2018, upfront issuance costs of RMB1.3 million and RMB0.7 million were included in other non-current assets, respectively. q) Revenue recognition The Group’s revenues comprise mainly auto shows revenue, group-purchase facilitation revenue, virtual dealership revenue and demand-side platform advertising services revenue. The Group adopted ASC Topic 606, "Revenue from Contracts with Customers" for all periods presented. Consistent with the criteria of Topic 606, the Group recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services using the five steps defined under ASC Topic 606. The Group assesses its revenue arrangements against specific criteria in order to determine if it is acting as principal or agent. Based on revenue arrangements, there are no multiple performance obligations identified. Revenue is recognized upon transfer of control of promised goods or services to a customer. Revenue is recorded net of Value Added Tax (“VAT”) and related surcharges collected from customers, which are subsequently remitted to government authorities. Auto shows revenue The Group’s online website and offline infrastructure allow them to organize auto shows, which aim at facilitating transactions between consumers and auto dealers that includes auto dealers, automakers and automotive service providers. The Group charges a fixed admission fee per auto show event to its industry customers for arranging, decorating and providing booth space at auto shows. The Group has identified one performance obligation for the transaction - providing a decorated venue for auto dealers, automakers and automotive service providers, as the individual service promised in auto show contracts are not distinct individually. As the Group has control of the auto show services and discretion in establishing the price of auto show admission fee to auto dealers, automakers and other automotive service providers, it is considered to be a principal in accordance with ASC 606. The auto shows revenue is recognized over the period of the contract when the services are provided. Group-purchase facilitation revenue The Group facilitates transactions between consumers and auto dealers by organizing group-purchase events. The Group charges group-purchase facilitation revenue to the auto dealers in the form of either a fixed fee per event or a fixed fee per car sold during the group-purchase event. There is no financing component or consideration payable to any consumers. The Group has identified one performance obligation - organizing group-purchase events. As the Group has control of the group-purchase facilitation services and discretion in establishing the price of group-purchase facilitation service fee, it is considered to be a principal in accordance with ASC 606. Since the Group’s performance obligation is satisfied once the transaction is complete, the group-purchase facilitation service revenue is recognized at the point in time when the service of group-purchase facilitation is rendered, which occurs upon the closing of the group-purchase event. Virtual dealership revenue The Group operates a virtual dealership by connecting automakers or franchised dealerships with secondary dealers whereby the Group purchases cars on behalf of the secondary dealers from the automakers or franchised dealerships. The Group charges a commission fee at a pre-agreed percentage of the car costs to the secondary dealers. As the Group has neither inventory risk nor the discretion to establish the cost of cars to secondary dealers, it is considered to be an agent in accordance with ASC 606. The virtual dealership commission revenue is recognized upon the secondary dealers’ acceptance of the delivery of cars from automakers or franchised dealerships. Demand-side platform advertising services revenue The Group’s demand-side platform advertising services revenue comprise mainly online advertising services of auto makers and auto dealers on the Group’s online website. The Group has identified one performance obligation for the transaction - providing online advertising services for auto makers and auto dealers. As the Group has control of online adverting services and discretion in establishing the price of online advertising services fee to auto makers and auto dealers, it is considered to be a principal in accordance with ASC 606. The demand-side platform advertising services revenue is recognized over the period of the contract when the online advertising services is provided. r) Cost of revenue Costs of revenues, consist primarily of rental costs for auto show venues, venue set-up costs, security costs, direct labor costs and other direct costs. s) Research and development expenses Research and development expenses mainly consist of payroll-related expenses incurred for the employees who develop and enhance to the Group's websites and platform of applications. t) Selling and marketing expenses Selling and marketing expenses consist primarily of advertising and promotional expenses, salaries and other compensation-related expenses for the Group's sales and marketing personnel. Advertising and promotional expenses consist primarily of costs for the promotion of corporate image and offline events. The Group expenses all advertising and promotional expenses as incurred and classifies them under selling and marketing expenses. For the years ended December 31, 2016, 2017 and 2018, the advertising and promotional expenses were RMB61.0 million, RMB134.2 million and RMB238.0million, respectively. u) Leases Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Rental expense is recognized from the date of initial possession of the leased property on a straight-line basis over the term of the lease. Certain lease agreements contain rent holidays, which are recognized on a straight-line basis over the lease term. Lease renewal periods are considered on a lease-by-lease basis and are generally not included in the initial lease terms. Rental costs for auto show venues incurred by the Group were RMB5.1 million, RMB31 million and RMB67 million for the years ended December 31, 2016, 2017 and 2018, respectively. Rental expenses for office space incurred by the Group were RMB10.4 million, RMB6.6 million and RMB6.6 million for the years ended December 31, 2016, 2017 and 2018, respectively. The Group has no capital leases for any of the periods presented. v) Share-based compensation Share based compensation expenses arise from share based awards, including share options for the purchase of ordinary shares and restricted shares. The Company accounts for share-based awards granted to employees in accordance with ASC 718 Compensation—Stock Compensation and share-based awards granted to non-employee in accordance with ASC 505. For share options for the purchase of ordinary shares granted to employees determined to be equity classified awards, the related share-based compensation expenses are recognized in the consolidated financial statements based on their grant date fair values which are calculated using the binomial option pricing model. The determination of the fair value is affected by the share price 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. The fair value of the ordinary shares is assessed using the income approach/discounted cash flow method, with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. Share-based compensation expenses are recorded net of actual forfeitures using straight-line method during the service period requirement, such that expenses are recorded only for those share-based awards that are expected to ultimately vest. Share-based compensation expenses for share options granted to non-employees are measured at fair value at the earlier of the performance commitment date or the date service is completed, and recognized over the period during which the service is provided. The Group applies the guidance in ASC 505-50 to measure share options granted to non-employees based on the then-current fair value at each reporting date. If a share-based award is modified after the grant date, the Group evaluates for such modifications in accordance with ASC 718 Compensation—Stock Compensation and if the modification is determined to be a probable-to-probable (Type 1) modification, additional compensation expenses are recognized in an amount equal to the excess of the fair value of the modified equity instrument over the fair value of the original equity instrument immediately before modification. The additional compensation expenses are recognized immediately on the date of modification or over the remaining requisite service period, depending on the vesting status of the award. w) 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, VIEs and subsidiaries of 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 RMB8.2 million, RMB10.8 million and RMB24.6 million for the years ended December 31, 2016, 2017 and 2018, respectively. x) 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 tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and any tax loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or tax laws is recognized in the consolidated statements of operations and comprehensive loss in the period the change in tax rates or tax laws is enacted. A valuation allowance is provided to reduce the amount of deferred income tax assets if it is considered more likely than not that some portion or all of the deferred income 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 approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Group recognizes interest and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheet and under other expenses in its consolidated statements of operations and comprehensive loss. The Group did not have any significant unrecognized uncertain tax positions as of and for the years ended December 31, 2016, 2017 and 2018. 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. z) Net loss per share Loss per share is computed in accordance with ASC 260, Earnings per Share. The two-class method is used for computing earnings per share in the event the Group has net income available for distribution. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company's preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. For the periods presented herein, the computation of basic loss per share using the two-class method is not applicable as the Group is in a net loss position and net loss is not allocated to other participating securities because in accordance with their contractual terms they are not obligated to share in the losses. Basic net loss per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of ordinary shares and potential ordinary shares outstanding during the period under treasury stock method. Potential ordinary shares include options to purchase ordinary shares and preferred shares, unless they were anti-dilutive. The computation of diluted net income/(loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income/(loss) per share. aa) Statutory reserves In accordance with China's Company Laws, the Company's VIEs in PRC must make appropriations from their after-tax profit (as determined under the accounting principles generally acceptable in China ("PRC GAAP")) to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appr

Income Tax Disclosure [Abstract]
Taxation	8. Taxation a) Income taxes Cayman Islands Under the current laws of the Cayman Islands, the Company is not subject to tax on income or capital gain. Additionally, upon payments of dividends by the Company in the Cayman Islands to their shareholders, no Cayman Islands withholding tax will be imposed. Hong Kong Subsidiary in Hong Kong is subject to 16.5% income tax for 2016, 2017 and 2018 on their taxable income generated from operations in Hong Kong. The payments of dividends by these company to their shareholders are not subject to any Hong Kong withholding tax. China Under the Enterprise Income Tax Law of the PRC, the Group’s Chinese subsidiaries and VIEs are subject to an income tax of 25%. The following table presents a reconciliation of the differences between the statutory income tax rate and the Company's effective income tax rate for the years ended December 31, 2016, 2017 and 2018: For the year ended December 31, 2016 2017 2018 % % % Statutory income tax rate of the PRC 25.0 25.0 25.0 Permanent differences (7.7 ) (11.5 ) (10.4 ) Change in valuation allowance (17.3 ) (13.5 ) (14.6 ) Effective income tax rate - - - As of December 31, 2018, certain entities of the Company had net operating tax loss carry forwards as follows: RMB Loss expiring in 2020 45,635 Loss expiring in 2021 28,344 Loss expiring in 2022 51,624 Loss expiring in 2023 2,150 127,753 b) Sales tax The Group's subsidiaries and VIEs incorporated in China are mainly subject to 6% VAT for services rendered. c) Deferred tax assets and liabilities The following table presents the tax impact of significant temporary differences that give rise to the deferred tax assets and liabilities as of December 31, 2017 and 2018: December 31, 2017 December 31, 2018 RMB RMB Deferred tax assets: Advertising expense in excess of deduction limit 385 25,473 Accrued expense and other payables 5,946 5,303 Net operating tax loss carry forwards 42,224 31,938 Total deferred tax assets 48,555 62,714 Less: valuation allowance (48,555 ) (62,714 ) Net deferred tax assets - - The Group does not believe that sufficient positive evidence exists to conclude that the recoverability of deferred tax assets of certain entities of the Group is more likely than not to be realized. Consequently, the Group has provided full valuation allowances on the related deferred tax assets. The following table sets forth the movement of the aggregate valuation allowances for deferred tax assets for the periods presented: Balance at January 1 Addition* Balance at December 31 RMB RMB RMB 2016 (32,914 ) (6,699 ) (39,613 ) 2017 (39,613 ) (8,942 ) (48,555 ) 2018 (48,555 ) (14,159 ) (62,714 ) * Additional valuation allowance was due to the increase of deferred tax assets recognised for advertising expenses in excess of deduction limit, accrued expense and other payables, and net operating tax loss carry forwards. d) Withholding income tax The enterprise income tax (“EIT”) Law also imposes a withholding income tax of 10% on dividends distributed by a foreign-invested entity ("FIE") to its immediate holding company outside of China, if such immediate holding company is considered as a non-resident enterprise without any establishment or place within China or if the received dividends have no connection with the establishment or place of such immediate holding company within China, unless such immediate holding company's jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. The Cayman Islands, where the Company incorporated, does not have such tax treaty with China. According to the arrangement between Mainland China and Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006, dividends paid by a FIE in China to its immediate holding company in Hong Kong will be subject to withholding tax at a rate that may be lowered to 5% (if the foreign investor owns directly at least 25% of the shares of the FIE). The State Administration of Taxation ("SAT") further promulgated Circular 601 on October 27, 2009, which provides that tax treaty benefits will be denied to "conduit" or shell companies without business substance and that a beneficial ownership analysis will be used based on a "substance-over-form" principle to determine whether or not to grant the tax treaty benefits.

Accounting for the Preferred Shares The Company has classified the Preferred Shares in the mezzanine equity of the consolidated balance sheets as they are contingently redeemable at the option of the holders. In addition, the Company records accretion to the redemption value from the issuance dates to the earliest redemption dates. The accretions are recorded against retained earnings, or in the absence of retained earnings, by charges against additional paid-in capital. Once additional paid-in capital has been exhausted, additional charges are recorded by increasing the accumulated deficit. Each issuance of the Preferred Shares is recognized at the respective issue price at the date of issuance net of issuance costs. The Company has determined that there was no beneficial conversion feature attributable to all preferred shares because the initial effective conversion prices of these preferred shares were higher than the fair value of the Company's common shares determined by the Company taking into account independent valuations. Upon the completion of the Company’s IPO in November 2018, all of the issued and outstanding pre-IPO Preferred Shares were automatically converted and redesignated into Class A ordinary shares based on the conversion rate stipulated in their Share Purchase Agreements. The Company’s preferred shares activities for the years ended December 31, 2016, 2017 and 2018 are summarized below: Pre-IPO China Best Pre-IPO Series A Pre-IPO Series B-1 Pre-IPO Series B-2 Pre-IPO Series C-1 Pre-IPO Series C-2 Pre-IPO Series C+ Number Amount Number Amount Number Amount Number Amount Number Amount Number Amount Number Amount RMB RMB RMB RMB RMB RMB RMB Balance as of January 1, 2016 5,660,000 1,695 19,798,750 5,109 12,428,343 8,671 22,742,215 35,125 3,427,812 14,352 33,408,715 144,631 - - Accretions to pre-IPO preferred shares redemption value - 126 - 467 - 376 - 3,330 - 1,066 - 11,540 - - Balance as of December 31, 2016 5,660,000 1,821 19,798,750 5,576 12,428,343 9,047 22,742,215 38,455 3,427,812 15,418 33,408,715 156,171 - - Issuance of pre-IPO preferred shares - - - - - - - - - - - - 18,855,298 88,640 Accretions to pre-IPO preferred shares redemption value - 126 - 472 - 382 - 3,376 - 1,080 - 11,698 - 3,811 Balance as of December 31, 2017 5,660,000 1,947 19,798,750 6,048 12,428,343 9,429 22,742,215 41,831 3,427,812 16,498 33,408,715 167,869 18,855,298 92,451 Issuance of pre-IPO preferred shares - - - - - - - - - - 483,702 7,093 - - Accretions to pre-IPO preferred shares redemption value - 68 - 409 - 330 - 2,922 - 935 - 10,123 - 6,069 Redesignation of pre-IPO preferred shares into Class A ordinary shares (5,660,000 ) (2,015 ) (19,798,750 ) (6,457 ) (12,428,343 ) (9,759 ) (22,742,215 ) (44,753 ) (3,427,812 ) (17,433 ) (33,892,417 ) (185,085 ) (18,855,298 ) (98,520 ) Balance as of December 31, 2018 - - - - - - - - - - - - - - Pre-IPO Series C-4 Pre-IPO Series D-1 Pre-IPO Series D-2 Mezzanine Number Amount Number Amount Number Amount Total Total RMB RMB RMB RMB Balance as of January 1, 2016 - - - - - - 97,465,835 209,583 Accretions to pre-IPO preferred shares redemption value - - - - - - - 16,905 Balance as of December 31, 2016 - - - - - - 97,465,835 226,488 Issuance of pre-IPO preferred shares - - - - - - 18,855,298 88,640 Accretions to pre-IPO preferred shares redemption value - - - - - - - 20,945 Balance as of December 31, 2017 - - - - - - 116,321,133 336,073 Issuance of pre-IPO preferred shares 7,569,628 42,826 10,046,551 150,811 21,579,948 358,567 39,679,829 559,297 Accretions to pre-IPO preferred shares redemption value - 1,808 - 7,009 - 5,393 - 35,066 Redesignation of pre-IPO preferred shares into Class A ordinary shares (7,569,628 ) (44,634 ) (10,046,551 ) (157,820 ) (21,579,948 ) (363,960 ) (156,000,962 ) (930,436 ) Balance as of December 31, 2018 - - - - - - - -

Share-based Compensation	15. Share-based Compensation (a) Description of stock option plan In July 2012, the Group permits the grant of options of the Company to relevant directors, officers, other employees and consultants of the Company. Option awards are granted with an exercise price determined by the Board of Directors. Those option awards generally vest over a period of four years. The Group recognizes share-based compensation expenses in the consolidated statements of operations and comprehensive loss based on awards ultimately expected to vest, after considering actual forfeitures. The Company has replaced these share options with restricted shares for all employees and non-employees on June 15, 2018 (Note 15(e)). As of December 31, 2018, total unrecognized compensation expenses related to unvested awards granted from 2012 to December 31, 2018, was RMB77.0 million. (b) Valuation assumptions The Group uses binomial option pricing model to determine fair value of the share-based awards. The estimated fair value of each option granted is estimated on the date of grant using the binomial option-pricing model with the following assumptions: 2016 2017 2018 Expected volatility 59.60%-62.40 % 57.90%-59.70 % 57.30 % Weighted average volatility 61.29 % 58.44 % 57.30 % Expected dividends - - - Risk-free rate 1.82%-2.70 % 2.60%-3.18 % 3.10 % Contractual term (in years) 10 10 10 Enterprise value US$0.30-US$0.32 US$0.32-US$0.65 US$0.65 The expected volatility at the grant date and each option valuation date was estimated based on the annualized standard deviation of the daily return embedded in historical share prices of comparable peer companies with a time horizon close to the expected expiry of the term of the options. The weighted average volatility is the expected volatility at the grant date weighted by number of options. The Company has never declared or paid any cash dividends on its capital stock, and the Group does not anticipate any dividend payments in the foreseeable future. Contractual term is the contract life of the options. The Group estimated the risk free interest rate based on the market yield of US Government Bond with maturity of ten years as of the valuation date, plus country default risk spread between United States and China.

No options were exercised for the years ended December 31, 2016, 2017 and 2018. (d) Founders’ shares In accordance with the restricted share agreement dated as of March 6, 2013, all ordinary shares ultimately owned by the Company’s founders would become subject to a vesting schedule, with 25% vesting on the first six months and the remainder vesting annually thereafter in equal instalments over the next three years. The founders’ shares vest immediately in the event that i) founder’s continuous status as a service provider is voluntarily terminated by the founders or ii) founder’s continuous status as a service provider is terminated by the Company for cause. The Company accounted for this arrangement similar to a reverse stock split, followed by the grant of restricted stock awards subject to service vesting conditions, though these founders’ shares are legally outstanding from the grant day. Accordingly, compensation cost was measured based on the fair value of the ordinary shares at the grant date and is recognized over the requisite service period. In connection with the issuance of series B-1, B-2, C-1 and C-2 convertible redeemable preferred shares, the Company amended the vesting schedule of all Founders’ shares under which founders’ restricted shares became subject to vesting with 1/36th of the options vesting each month after the issuance of each series of convertible redeemable preferred shares. The change in in vesting schedule was treated as a modification of the award and did not result in a modification charge as there was no incremental value resulted from the modification. For the years ended December 31, 2016, 2017 and 2018, the Company recognized share based compensation expense related to the founders’ shares of US$0.2 million, nil and nil, respectively. Grant date fair value per restricted share is US$0.01. Restricted shares Number of shares Outstanding as of January 1, 2016 15,949,454 Restricted shares vested (15,949,454 ) Outstanding as of December 31, 2016 - Restricted shares vested - Outstanding as of December 31, 2017 - Restricted shares vested - Outstanding as of December 31, 2018 - (e) Share option replacement In June 2018, the directors of the Company (the “Directors”) had approved, the TuanChe Limited Share Incentive Plan (the “Plan”). Under the Plan, 38,723,321 ordinary shares were issued to Best Cars which is a VIE of the Company for the restricted share awards at consideration of nil. Meanwhile, the incentive share options granted to employees and non-employees of the Company shall be replaced by the restricted shares. As a result of the Plan, on June 15, 2018, a total of 15,473,653 share options of the Company were replaced by 13,740,480 restricted shares. The restricted shares awards are subject to the original vesting schedule of the replaced share options. The Company concluded the cancellation and replacement of awards is a modification, and determined the modification is a probable-to-probable (Type 1) modification. The Company has recognized the portion of incremental value of RMB10.7 million as expenses immediately for those vested share options; the portion of the incremental value of RMB3.7 million as the result of the replacement for unvested share options will be recognized as expenses over the remaining vesting periods of 1 to 4 years. Concurrently, the Company newly granted 10,666,704 restricted shares to its employees. The total fair value of RMB109.0 million for those newly granted restricted shares will be recognized as expenses over the vesting periods of nil to 4 years. A summary of the restricted shares activities is presented below: Number of restricted Weighted-Average US$ Outstanding as of January 1, 2018 - - Granted 24,407,184 1.595 Vested (12,917,926 ) 1.595 Outstanding as of December 31, 2018 11,489,258 1.595 For the year ended December 31, 2018, total share-based compensation expenses recognized by the Group for the share options and restricted shares granted were RMB0.6 million and RMB71.2 million, respectively. As of December 31, 2018, there were RMB77.0 million of unrecognized share-based compensation expenses related to the restricted shares granted. That expenses are expected to be recognized over a weighted-average period of 2.97 years. (f) Super voting right On June 13, 2018, the Company’s changed its capital structure to re-designate its ordinary shares into Class A ordinary shares and Class B ordinary shares. The effect of this re-designation has been accounted for retroactively for all periods presented. Mr. Wei Wen, Chairman of the Board of Directors and CEO of the Company holds Class B ordinary shares through his British Virgin Islands (“BVI”) company and each Class B ordinary share carries fifteen (15) votes at meetings of shareholders. Upon further transfer of Class B ordinary shares by Mr. Wei Wen to anyone, such Class B ordinary shares will automatically convert into an equal number of Class A ordinary shares. The grant of the super voting right was authorized by the Board of Directors on June 13, 2018. There are no additional vesting conditions attached to the grant. Accordingly, the Company recognized the incremental value of RMB4.7 million of Class B ordinary shares in general and administrative expenses as share based compensation on the grant date. (g) Ordinary shares On September 29, 2018, the Class A ordinary share holder of the Company, First Aqua Inc., entered into a share transfer agreement with ACEE Capital Ltd., the Series D-1 preferred share holder of the Company, to transfer 521,962 Class A Ordinary Shares to ACEE Capital Ltd., for an aggregate selling price of US$1.1 million. The transfer of Class A ordinary shares was authorized by the Board of Directors on September 28, 2018. Accordingly, the Company recognized the incremental value of RMB1.7 million between the consideration and the fair value of 521,962 Class A ordinary shares in general and administrative expenses as share based compensation on the transfer date. 16. Net Loss Per Share For the years ended December 31, 2016, 2017 and 2018, the Company had potential ordinary shares, including preferred shares, restricted shares and share options granted. As the Group incurred losses for the years ended December 31, 2016, 2017 and 2018, these potential preferred shares and shares options granted were anti-dilutive and excluded from the calculation of diluted net loss per share of the Company. The numbers of preferred shares, share options and convertible loan excluded from the calculation of diluted net loss per share of the Company were 97,465,835, 20,634,496 and 6,261,743 as of December 31, 2016, the numbers of preferred shares, share options, convertible loan and warrant exclude from the calculation of diluted net loss per share of the Company were 116,321,133, 18,817,362, 7,569,628 and 670,814 as of December 31, 2017 and the numbers of preferred shares, share options, convertible loan and warrant exclude from the calculation of diluted net loss per share of the Company were nil, nil, nil and nil as of December 31, 2018. Considering that the holder of preferred shares has no contractual obligation to participate in the Company’s losses, any losses from the Group should not be allocated to preferred shares.

Fair Value Disclosures [Abstract]
Fair Value Measurement	20. Fair Value Measurement Assets and liabilities disclosed at fair value The Company measures its cash and cash equivalents, restricted cash, short-term investments, short-term borrowings and convertible loans at amortized cost. The fair value was estimated by discounting the scheduled cash flows through to estimated maturity using estimated discount rates based on current offering rates of comparable institutions with similar services. The carrying value of the Company's debt obligations approximate fair value as the borrowing rates are similar to the market rates that are currently available to the Company for financing obligations with similar terms and credit risks and represent a level 2 measurement. Assets measured at fair value on a nonrecurring basis The Company measured its property, equipment and software, long-term investment at fair value on a nonrecurring basis whenever events or changes in circumstances indicate that the carrying value may no longer be recoverable. Assets and liabilities measured at fair value on a recurring basis The Company measured its warrant at fair value on a recurring basis. As the Company's warrant is not traded in an active market with readily observable prices, the Company uses significant unobservable inputs to measure the fair value of warrant. This instrument are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. The Company did not transfer any assets or liabilities in or out of level 3 during the years ended December 31, 2016, and 2017. In 2018, the Company transferred the warrant out of level 3 to mezzanine as China Equities has effected a net cashless exchange of the warrant for 483,702 Series C-2 convertible redeemable preferred shares on September 29, 2018. The following table summarizes the Company's financial liabilities measured and recorded at fair value on recurring basis as of December 31, 2017 and 2018: As of December 31, 2017 Active Market Observable Input Non-observable Input (Level 1) (Level 2) (Level 3) Total RMB RMB RMB RMB Liability: Warrant - - 2,818 2,818 As of December 31, 2018 Active Market Observable Input Non-observable Input (Level 1) (Level 2) (Level 3) Total RMB RMB RMB RMB Liability: Warrant - - - - Warrant The Company adopted Black Scholes model to assess the warrant's fair value. Management is responsible for determining the fair value and assessing a number of factors. The valuation involves complex and subjective judgements as well as the Company's best estimates on the valuation date. Key inputs related to the Black Scholes model for the valuation of the fair value of warrants are: expiry date of warrant, fair market value per share as of valuation date, exercise price, risk free rate of interest, dividend yield, expected time to exercise as well as volatility.

Restricted Assets Net [Abstract]
Restricted Net Assets	21. Restricted Net Assets Relevant PRC laws and regulations permit PRC companies to pay dividends only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Additionally, the Company's PRC subsidiaries, VIEs and subsidiaries of VIEs can only distribute dividends upon approval of the shareholders after they have met the PRC requirements for appropriation to the general reserve fund and the statutory surplus fund respectively. The general reserve fund and the statutory surplus fund require that annual appropriations of 10% of net after-tax income should be set aside prior to payment of any dividends. As a result of these and other restrictions under PRC laws and regulations, the PRC subsidiaries, VIEs and subsidiaries of VIEs are restricted in their ability to transfer a portion of their net assets to the Company either in the form of dividends, loans or advances, which restricted portion amounted to approximately RMB139.9 million as of December 31, 2018. Even though the Company currently does not require any such dividends, loans or advances from the PRC subsidiaries, VIEs and subsidiaries of VIEs for working capital and other funding purposes, the Company may in the future require additional cash resources from its PRC subsidiaries, VIEs and subsidiaries of VIEs due to changes in business conditions, to fund future acquisitions and developments, or merely declare and pay dividends to or distributions to the Company's shareholders.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Condensed Financial Information Disclosure [Abstract]
Basis of presentation	a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with 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 The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIEs and subsidiaries of VIEs for which the Company is the primary beneficiary. 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 transactions and balances among the Company, its subsidiaries, VIEs and subsidiaries of VIEs have been eliminated upon consolidation.
Discontinued operations	c) Discontinued operations A component of a reporting entity or a group of components of a reporting entity that are disposed or meet the criteria to be classified as held for sale, such as the management, having the authority to approve the action, commits to a plan to sell the disposal group, should be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Discontinued operations are reported when a component of an entity comprising operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the entity is classified as held for disposal or has been disposed of, if the component either (1) represents a strategic shift or (2) have a major impact on an entity’s financial results and operations. In the consolidated statements of operations and comprehensive loss, result from discontinued operations is reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinuing operations are presented separately in Note 3. In order to present the financial effects of the continuing operations and discontinued operations, revenues and expenses arising from intra-group transactions are eliminated except for those revenues and expenses that are considered to continue after the disposal of the discontinued operations. Inventories comprise electric vehicles on display at show rooms. Inventories are valued at the lower of cost or net realizable value. Cost of inventories is determined by the weighted-average method. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. The Group continually evaluates the recoverability based on assumptions about future customer demand and market conditions. The evaluation may take into consideration inventory aging, expected demand, anticipated sales price, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future customer demand and market conditions. As of December 31, 2017 and 2018, there was no write-down of inventories. Non-current assets or disposal groups are classified as assets held for sale when the carrying amount is to be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such asset. The Group purchases cars on behalf of consumers from auto makers and auto dealers. As the Group is not primarily responsible for the acceptability of the electric vehicles and does not assume inventory risk of the cars, it is considered to be an agent in accordance with ASC 606. Commission income upon each successful sale is recognized at a point in time following the transfer of control of cars. As of December 31, 2017, the prepayments and other current assets, inventories, property, equipment and software and other current liabilities related to the Discontinued Business are classified as “Held-for-sale” in the consolidated financial statements of the Group. On June 30, 2018, the Company completed the disposal of the Discontinued Business.
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 that 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, assessment for valuation allowance of deferred tax assets, determination of the fair value of ordinary shares, preferred shares and warrant, and valuation and recognition of share-based compensation expenses.
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 and its overseas subsidiaries which incorporated in the Cayman Islands and Hong Kong is United States dollars ("US$"). The functional currency of the Group's PRC entities is RMB. In the consolidated financial statements, the financial information of the Company and other entities located outside of the PRC have been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, and expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. Net gains and losses resulting from foreign exchange transactions are included in exchange (losses)/gains in the consolidated statements of operations and comprehensive loss.
Convenience Translation	f) Convenience Translation Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2018 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.8755, representing the the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2018. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2018, or at any other rate.
Fair value measurements	g) Fair value measurements Accounting guidance defines fair value as 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. Accounting guidance establishes 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 establishes three levels of inputs that may be used to measure fair value: · Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. · Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical asset or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. · Level 3 applies to asset or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. The Group's financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, other receivables, accounts payable, short-term borrowings and other payables, of which the carrying values approximate their fair value. See Note 20 for additional information.
Cash, cash equivalents and restricted cash	h) Cash, cash equivalents and restricted cash Cash and cash equivalents mainly represent cash on hand, demand deposits placed with large reputable banks in the United States of America or China, and highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase with terms of three months or less. As of December 31, 2017 and 2018, there were cash at bank and demand deposits with terms of less than three months denominated in US dollars amounting to approximately US$5.3 million and US$73.5 million, respectively (equivalent to approximately RMB34.4 million and RMB504.2 million, respectively). As of December 31, 2017 and 2018, the Group had approximately RMB32.2 million and RMB74.4 million cash and cash equivalents held by its PRC subsidiaries, VIEs and subsidiaries of VIEs, representing 48.3% and 12.9% of total cash and cash equivalents of the Group, respectively. As of December 31, 2017 and 2018, the Company had a restricted cash balance approximately RMB11.1 million and nil, respectively, which is a deposit in bank and held as collateral for the Group’s VIE’s short-term borrowing. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash. Therefore, amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. The Company early adopted the amendments in fiscal year 2016. The changes in restricted cash in the consolidated statements of cash flows were RMB11.1 million and RMB(11.1) million for the years ended December 31, 2017 and 2018, respectively.
Accounts receivable, net	i) Accounts receivable, net The carrying value of accounts receivable is reduced by an allowance that reflects the Group’s best estimate of the amounts that will not be collected. Many factors are considered in estimating the general allowance, including but not limited to reviewing accounts receivable balances, historical bad debt rates, aging analysis, customer credit worthiness and industry trend analysis. The Group also makes the specific allowance if there is evidence showing that the receivable is unlikely to be collected. Accounts receivable balances are written off against the allowance when they are determined to be uncollectible. Refer to Note 4 for details.
Short-term investments	j) Short-term investments Short-term investments mainly comprised of wealth management products, highly liquid investments placed with banks with original maturities longer than three months but within one year, and interest generating loan provided to a third party. As of December 31, 2017 and 2018, the interest generating loan provided to a third party of the Group was RMB4.0 million and nil, respectively. The interest generating loan provided to a third party was fully collected on July 3, 2018.
Property, equipment and software, net	k) 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 following estimated useful lives: Furniture and electronic equipment 3 years Vehicles 10 years Software 5 years Leasehold improvements Shorter of expected lives of leasehold improvements and lease term 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.
Assets and liabilities held-for-sale	l) Assets and liabilities held-for-sale Assets and liabilities to be sold shall be classified as held-for-sale considering the recognition criteria in which all of the following criteria are met: · Management, having the authority to approve the action, commits to a plan to sell the assets and liabilities. · The assets and liabilities are available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets. · An active program to locate a buyer and other actions required to complete the plan for the sale has been initiated. · The sale is probable, and transfer of the asset is expected to qualify for recognition as a completed sale, within one year, · The assets and liabilities are being actively marketed for sale at a price that is reasonable in relation to its current fair value. · Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
Impairment of long-lived assets	m) 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 impact 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. No impairment charge was recognized for any of the periods presented.
Long-term investments	n) Long-term investments In accordance with ASC 325 Investment—Other, for investments in equity instruments which the Company does not have significant influence, and whose fair value is not readily determinable, the cost method accounting is applied. Gain or losses are realized when such investment is sold or when dividends are declared or payments are received. The Company assesses its equity investments for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, the operating performance of the companies including current earnings trends, and other company-specific information such as financing rounds. Investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC topic 323 Investments-Equity Method and Joint Ventures. The Company adjusts the carrying amount of equity method investment for its share of the income or losses of the investee and reports the recognized income or losses in the consolidated statements of operations and comprehensive loss. The Company’s share of the income or losses of an investee are based on the shares of common stock and in-substance common stock held by the Company.
Other non-current assets	o) Other non-current assets As of December 31, 2018, other non-current assets comprises mainly prepayments for the purchases of softwares.
Warrant	p) Warrant On October 31, 2017, a warrant to purchase Series C-2 convertible redeemable preferred shares of the Company was issued in connection with the debt financing and is classified as a liability and is treated as upfront issuance costs based on the estimated fair value of the warrant at issuance date. Subsequently, changes in the fair value of the warrant for Series C-2 convertible redeemable preferred shares is recorded in the consolidated statements of operations and comprehensive loss. The upfront issuance costs are amortized over the term of the debt financing. As of December 31, 2017 and 2018, upfront issuance costs of RMB1.3 million and RMB0.7 million were included in other non-current assets, respectively.
Revenue recognition	q) Revenue recognition The Group’s revenues comprise mainly auto shows revenue, group-purchase facilitation revenue, virtual dealership revenue and demand-side platform advertising services revenue. The Group adopted ASC Topic 606, "Revenue from Contracts with Customers" for all periods presented. Consistent with the criteria of Topic 606, the Group recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services using the five steps defined under ASC Topic 606. The Group assesses its revenue arrangements against specific criteria in order to determine if it is acting as principal or agent. Based on revenue arrangements, there are no multiple performance obligations identified. Revenue is recognized upon transfer of control of promised goods or services to a customer. Revenue is recorded net of Value Added Tax (“VAT”) and related surcharges collected from customers, which are subsequently remitted to government authorities. Auto shows revenue The Group’s online website and offline infrastructure allow them to organize auto shows, which aim at facilitating transactions between consumers and auto dealers that includes auto dealers, automakers and automotive service providers. The Group charges a fixed admission fee per auto show event to its industry customers for arranging, decorating and providing booth space at auto shows. The Group has identified one performance obligation for the transaction - providing a decorated venue for auto dealers, automakers and automotive service providers, as the individual service promised in auto show contracts are not distinct individually. As the Group has control of the auto show services and discretion in establishing the price of auto show admission fee to auto dealers, automakers and other automotive service providers, it is considered to be a principal in accordance with ASC 606. The auto shows revenue is recognized over the period of the contract when the services are provided. Group-purchase facilitation revenue The Group facilitates transactions between consumers and auto dealers by organizing group-purchase events. The Group charges group-purchase facilitation revenue to the auto dealers in the form of either a fixed fee per event or a fixed fee per car sold during the group-purchase event. There is no financing component or consideration payable to any consumers. The Group has identified one performance obligation - organizing group-purchase events. As the Group has control of the group-purchase facilitation services and discretion in establishing the price of group-purchase facilitation service fee, it is considered to be a principal in accordance with ASC 606. Since the Group’s performance obligation is satisfied once the transaction is complete, the group-purchase facilitation service revenue is recognized at the point in time when the service of group-purchase facilitation is rendered, which occurs upon the closing of the group-purchase event. Virtual dealership revenue The Group operates a virtual dealership by connecting automakers or franchised dealerships with secondary dealers whereby the Group purchases cars on behalf of the secondary dealers from the automakers or franchised dealerships. The Group charges a commission fee at a pre-agreed percentage of the car costs to the secondary dealers. As the Group has neither inventory risk nor the discretion to establish the cost of cars to secondary dealers, it is considered to be an agent in accordance with ASC 606. The virtual dealership commission revenue is recognized upon the secondary dealers’ acceptance of the delivery of cars from automakers or franchised dealerships. Demand-side platform advertising services revenue The Group’s demand-side platform advertising services revenue comprise mainly online advertising services of auto makers and auto dealers on the Group’s online website. The Group has identified one performance obligation for the transaction - providing online advertising services for auto makers and auto dealers. As the Group has control of online adverting services and discretion in establishing the price of online advertising services fee to auto makers and auto dealers, it is considered to be a principal in accordance with ASC 606. The demand-side platform advertising services revenue is recognized over the period of the contract when the online advertising services is provided.
Cost of revenue	r) Cost of revenue Costs of revenues, consist primarily of rental costs for auto show venues, venue set-up costs, security costs, direct labor costs and other direct costs.
Research and development expenses	s) Research and development expenses Research and development expenses mainly consist of payroll-related expenses incurred for the employees who develop and enhance to the Group's websites and platform of applications.
Selling and marketing expenses	t) Selling and marketing expenses Selling and marketing expenses consist primarily of advertising and promotional expenses, salaries and other compensation-related expenses for the Group's sales and marketing personnel. Advertising and promotional expenses consist primarily of costs for the promotion of corporate image and offline events. The Group expenses all advertising and promotional expenses as incurred and classifies them under selling and marketing expenses. For the years ended December 31, 2016, 2017 and 2018, the advertising and promotional expenses were RMB61.0 million, RMB134.2 million and RMB238.0million, respectively.
Leases	u) Leases Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Rental expense is recognized from the date of initial possession of the leased property on a straight-line basis over the term of the lease. Certain lease agreements contain rent holidays, which are recognized on a straight-line basis over the lease term. Lease renewal periods are considered on a lease-by-lease basis and are generally not included in the initial lease terms. Rental costs for auto show venues incurred by the Group were RMB5.1 million, RMB31 million and RMB67 million for the years ended December 31, 2016, 2017 and 2018, respectively. Rental expenses for office space incurred by the Group were RMB10.4 million, RMB6.6 million and RMB6.6 million for the years ended December 31, 2016, 2017 and 2018, respectively. The Group has no capital leases for any of the periods presented.
Share-based compensation	v) Share-based compensation Share based compensation expenses arise from share based awards, including share options for the purchase of ordinary shares and restricted shares. The Company accounts for share-based awards granted to employees in accordance with ASC 718 Compensation—Stock Compensation and share-based awards granted to non-employee in accordance with ASC 505. For share options for the purchase of ordinary shares granted to employees determined to be equity classified awards, the related share-based compensation expenses are recognized in the consolidated financial statements based on their grant date fair values which are calculated using the binomial option pricing model. The determination of the fair value is affected by the share price 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. The fair value of the ordinary shares is assessed using the income approach/discounted cash flow method, with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. Share-based compensation expenses are recorded net of actual forfeitures using straight-line method during the service period requirement, such that expenses are recorded only for those share-based awards that are expected to ultimately vest. Share-based compensation expenses for share options granted to non-employees are measured at fair value at the earlier of the performance commitment date or the date service is completed, and recognized over the period during which the service is provided. The Group applies the guidance in ASC 505-50 to measure share options granted to non-employees based on the then-current fair value at each reporting date. If a share-based award is modified after the grant date, the Group evaluates for such modifications in accordance with ASC 718 Compensation—Stock Compensation and if the modification is determined to be a probable-to-probable (Type 1) modification, additional compensation expenses are recognized in an amount equal to the excess of the fair value of the modified equity instrument over the fair value of the original equity instrument immediately before modification. The additional compensation expenses are recognized immediately on the date of modification or over the remaining requisite service period, depending on the vesting status of the award.
Employee benefits	w) 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, VIEs and subsidiaries of 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 RMB8.2 million, RMB10.8 million and RMB24.6 million for the years ended December 31, 2016, 2017 and 2018, respectively.
Taxation	x) 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 tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and any tax loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or tax laws is recognized in the consolidated statements of operations and comprehensive loss in the period the change in tax rates or tax laws is enacted. A valuation allowance is provided to reduce the amount of deferred income tax assets if it is considered more likely than not that some portion or all of the deferred income 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 approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Group recognizes interest and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheet and under other expenses in its consolidated statements of operations and comprehensive loss. The Group did not have any significant unrecognized uncertain tax positions as of and for the years ended December 31, 2016, 2017 and 2018.
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.
Net loss per share	z) Net loss per share Loss per share is computed in accordance with ASC 260, Earnings per Share. The two-class method is used for computing earnings per share in the event the Group has net income available for distribution. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company's preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. For the periods presented herein, the computation of basic loss per share using the two-class method is not applicable as the Group is in a net loss position and net loss is not allocated to other participating securities because in accordance with their contractual terms they are not obligated to share in the losses. Basic net loss per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of ordinary shares and potential ordinary shares outstanding during the period under treasury stock method. Potential ordinary shares include options to purchase ordinary shares and preferred shares, unless they were anti-dilutive. The computation of diluted net income/(loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income/(loss) per share.
Statutory reserves	aa) Statutory reserves In accordance with China's Company Laws, the Company's VIEs in PRC must make appropriations from their after-tax profit (as determined under the accounting principles generally acceptable in China ("PRC GAAP")) to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the respective company. Appropriation to the discretionary surplus fund is made at the discretion of the respective company. Pursuant to the laws applicable to China's Foreign Investment Enterprises, the Company's subsidiaries that are foreign investment enterprises in China have to make appropriations from their after-tax profit (as determined under PRC GAAP) to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the respective company. Appropriations to the other two reserve funds are at the respective companies' discretion. The Group has not appropriated any amount to statutory reserves for the years ended December 31, 2016, 2017 and 2018, because its PRC entities were making losses under the PRC GAAP in these years.
Comprehensive income/(loss)	bb) Comprehensive income/(loss) Comprehensive income/(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. Other comprehensive income/(loss), as presented on the consolidated balance sheets, consists of accumulated foreign currency translation adjustments.
Segment reporting	cc) Segment reporting The Group uses the management approach in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Group’s chief operating decision maker for making operating decisions, allocating resources and assessing performance as the source for determining the Group’s reportable segments. Management has determined that the Group operated its continuing operations in one segment, as that term is defined by FASB ASC Topic 280, Segment reporting.
Concentrations and Risks	dd) Concentrations and Risks Online advertising and promotional service provider The Group relied on online advertising and promotional service providers and their affiliates for online advertising and promotional service to support its operations during the years ended December 31, 2016, 2017 and 2018 as follows: For the year ended December 31, 2016 2017 2018 Total number of online advertising and promotional service providers 17 21 32 Number of online service providers that accounted for 10% or more of the Group's online advertising and promotional service 1 2 2 Total percentage of the Group's online advertising and promotional service expenses that were paid to these service providers who accounted for 10% or more of the Group’s online advertising and promotional service expenses. 59 % 50 % 43 % Credit risk Financial instruments that potentially subject the Group to the concentration of credit risk consist of cash and cash equivalents, restricted cash, accounts receivable and short-term investments. As of December 31, 2017 and 2018, all of the Group's cash and cash equivalents, and restricted cash were held in major financial institutions located in the United States of America or China, which management consider being of high credit quality. Accounts receivable is typically unsecured and is mainly derived from revenue earned from auto shows business. Short-term investments consist of interest generating loan provided to a third party of the Group, which was repaid on July 3, 2018. Major customers There was nil and one customer had receivable balances exceeding l0% of the total accounts receivable balances of the Group as of December 31, 2017 and 2018, respectively, as follows: For the year ended December 31, 2017 2018 Customer A - 22 %
Recently issued accounting pronouncements	ee) Recently issued accounting pronouncements The Group qualifies as an “emerging growth company”, or “EGC”, pursuant to the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act. As an EGC, the Group does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. In January 2016, the FASB issued ASU No. 2016-01 Financial Instruments—Overall (Subtopic 825-10) "Recognition and Measurement of Financial Assets and Financial Liabilities". The amendments in this ASU require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this accounting standard update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this accounting standard update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other entities including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Group adopted this new standard effective on January 1, 2019. The adoption of ASU 2016-01 did not have a material impact on the Group’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires that a lessee should recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expenses for such lease generally on a straight-line basis over the lease term. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public entities. For all other entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application of the amendments in this update is permitted for all entities. The Group is currently evaluating the impact ASU 2016-02 will have on the Group's consolidated financial statements, and expects that some existing operating lease commitments will be recognized as operating lease obligations and right-of-use assets as a result of adoption. In June 2016, the FASB amended guidance related to the impairment of financial instruments as part of ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For all other public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. For all other entities, including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this update are effective for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. All entities may adopt the amendments in this update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The guidance replaces the incurred loss impairment methodology with an expected credit loss model for which the Group is required to recognize an allowance based on its estimate of expected credit loss. The Group is currently evaluating the impact of this new guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides guidance for targeted changes with respect to how cash receipts and cash payments are classified in the statements of cash flows, with the objective of reducing diversity in practice. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The Group is in the process of evaluating the impact of this accounting standard update on its consolidated statements of cash flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) ("ASU 2016-18"). This ASU affects all entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The Group has early adopted this accounting standard on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07 Compensation—Stock Compensation (Topic 718) "Improvements to Nonemployee Share-Based Payment Accounting". The amendments in this update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Group is in the process of evaluating the impact of this accounting standard update on its consolidated financial statements.
