Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Principal Activities	1. ORGANIZATION AND PRINCIPAL ACTIVITIES GreenTree Hospitality Group Ltd. (the “Company”) was incorporated in the Cayman Islands on October 18, 2017. Alex S. Xu is the founder, Chief Executive Officer (“CEO”) and controlling shareholder of the Company (through his shareholding of Class A ordinary shares and Class B ordinary shares of Green Tree Inns Hotel Management Group. Inc. “GTI”) which account for 78.19% of the voting interest of the Company (the “Founder”). In preparation of its initial public offering in the United States, the Company had undergone a reorganization in 2017 whereby the Company became the parent entity of its consolidated subsidiaries. As part of the reorganization, the business operations of the consolidated subsidiaries were transferred to the Company. In return, the Company issued 48,635,252 Class A ordinary shares and 42,716,957 Class B ordinary shares to GTI, a company controlled by the Founder (the “Reorganization”). Subsequent to the Reorganization, GTI became the sole shareholder of the Company. As the Company, its subsidiaries are all under the control of the Founder, the reorganization was accounted for as a transaction under common control in a manner similar to a pooling of interests. Therefore, the accompanying consolidated financial statements have been prepared as if the corporate structure of the Company had been in existence since the beginning of the periods presented. In February and March 2018, the Company declared and paid a cash dividend of USD25,578,618 pursuant to a board resolution.

The Company offered 10,200,000 ADSs representing 10,200,000 Class A ordinary shares at USD14.00 per ADS. Net proceeds from the IPO deducting underwriting discount were USD133,518,000. IPO costs of RMB30,827,578 were recorded as reduction of the proceeds from the IPO in shareholders’ equity. In January 2019, the Company declared and paid a cash dividend of USD30,559,675 pursuant to a board resolution. On January 25, 2019 and June 27, 2019, the Company issued an aggregate of 626,746 Class A ordinary shares as a portion of the purchase consideration for the acquisition of 60% equity interest mainly in Argyle Hotel Management (Beijing) Co., Ltd (“Argyle Beijing”).

Accounting Policies [Abstract]
SUMMARY OF PRINCIPAL ACCOUNTING POLICIES	2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES Basis of presentation The consolidated financial statements of the Group have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”). Basis of consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries and the consolidated VIEs for which the Company is the ultimate primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation. The Group evaluates its business activities and arrangements with the entities that operate the franchised-and-managed hotels to identify potential variable interest entities. Generally, these entities qualify for the business scope exception; therefore, consolidation is not appropriate under the variable interest entity consolidation guidance. Variable Interest Entities The Group evaluates the need to consolidate certain variable interest entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. The Company is deemed as the primary beneficiary of and consolidates variable interest entities when the Company has the power to direct the activities that most significantly impact the economic success of the entities and effectively assumes the obligation to absorb losses and has the rights to receive benefits that are potentially significant to the entities. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Use of estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences could be material to the consolidated financial statements. The Group bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Significant accounting estimates reflected in the Group’s consolidated financial statements include allowance for doubtful accounts receivable, impairment of loans receivable, fair value measurement and impairment of investments, the useful lives and impairment of property and equipment and intangible assets, valuation allowance for deferred tax assets, impairment of goodwill, average life of memberships, estimates involved in the accounting for its membership program, contingent liabilities, purchase price allocation and share-based compensation arrangements. Cash and cash equivalents Cash and cash equivalents include cash on hand and demand deposits placed with commercial banks or other financial institutions and highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of three months or less. All cash and cash equivalents are unrestricted as to withdrawal and use. Restricted cash Restricted cash comprise of deposits pledged with banks as security in relation to the guarantee for lease agreement and the guarantees for prepaid cards. Long-term time deposits Long-term time deposits comprise of deposits placed with certain bank with a maturity of one 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Investments Short-term investments Short-term investments include time deposits with maturities of less than one year and investments in wealth management products, where certain deposits with variable interest rates or where principal amounts are not guaranteed, are placed with certain financial institutions. The Group accounts for short-term investments in debt in accordance with ASC topic 320, Investments—Debt Securities (“ASC 320”). The Group classifies the short-term investments in debt as “held-to-maturity”, “trading” or “available-for-sale”, whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at acquisition, for all categories of investments in securities, are included in earnings. Any realized gains or losses on the sale of the short-term investments, are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. The securities that the Group has the positive intent and the ability to hold to maturity are classified as held-to-maturity securities and stated at amortized cost. RMB80,000,000 (USD12,553,746) of which was pledged with banks as security in relation to the guarantee for the short-term bank loans and restricted to use (Note 11). Investments in equity securities The Group accounts for its investments in equity securities in accordance with ASC Subtopic 321, Investments – Equity Securities Long-term investments The Group’s long-term investments consist of equity-method investments, equity investments with and without readily determinable fair values and an available-for-sale debt investment. Investments in entities in which the Group 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 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Investments (continued) Long-term investments (continued) Investments in equity securities that have readily determinable fair values (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) are measured at fair value, with unrealized gains and losses from fair value changes recognized in net income in the consolidated statements of comprehensive income. The realized gains of RMB4,674,446, RMB4,746,032 and RMB1,564,892 (USD245,566) were recognized for the years ended December 31, 2019, 2020 and 2021, respectively. For the year ended December 31, 2019, there were unrealized gains of RMB6,473,358. For the year ended December 31, 2020 and 2021, there were unrealized losses of RMB9,247,254 and RMB14,058,448 (USD2,206,077) respectively. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The available-for-sale debt investment is convertible debt instruments issued by a private company that is redeemable at the Group’s option, which are measured at fair value. Interest income is recognized in earnings. All other changes in the carrying amount of these debt investments are recognized in other comprehensive income. An impairment loss on the available-for-sale debt investments, if any, is recognized in earnings when the decline in value is determined to be other-than-temporary. The interest income of nil, RMB18,667,117 and RMB544,352 (USD 85,421) was recognized in the earnings for the years ended December 31, 2019, 2020 and 2021, respectively. The fair value change of RMB2,791,663 (USD438,073) was recognized in the other comprehensive income during the year ended December 31, 2021. No impairment or significant fair value changes were recorded for these investments during any of other presented periods. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Accounts receivable, net of allowance for doubtful accounts Trade receivables mainly consist of franchise fees receivable, rental amounts due from individual and corporate customers and travel agents, and sublease rental receivables due from third-party merchandisers, which are recognized and carried at the original invoice amounts less an allowance for doubtful accounts. The Group establishes an allowance for doubtful accounts primarily based on the age of the receivables and factors surrounding the credit risk of specific franchisees, customers, and merchandisers. Accounts receivable balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Inventories Inventories mainly consist of small appliances, bedding and daily consumables. Small appliances and bedding are stated at cost, less accumulated amortization, and are amortized over their estimated useful lives, generally one year, from the time they are put into use. Daily consumables are expensed when used. Loans receivable Loans receivable are carried at the original loan principal and accrued interest based on the contract rate, less an allowance for uncollectible accounts, as appropriate. The Group classified loans receivable as long-term or short-term investments according to their contractual maturity. The allowance for uncollectible accounts is estimated based on an assessment of the payment history, the existence of collateral, current information and events, and the facts and circumstances around the credit risk of the debtors. As of December 31, 2020 and 2021, all loans receivable which are past due are nonaccrual Property and equipment, net Property and equipment, net are stated at cost less accumulated depreciation and any recorded impairment. Depreciation of property and equipment is provided using the straight-line method over the following expected useful lives: ​ ​ ​ Leasehold improvements Over the shorter of the lease term or estimated useful lives Buildings ​ 20 years Furniture, fixtures and equipment ​ 3-5 years Motor vehicles ​ 5 years ​ Construction in progress represents leasehold improvements under construction or being installed and is stated at cost. Cost comprises original cost of property and equipment, installation, construction and other direct costs. Construction in progress is transferred to leasehold improvements and depreciation commences when the asset is ready for its intended use. Expenditures for repairs and maintenance are expensed as incurred, whereas the costs of betterments that extend the useful life of property and equipment are capitalized as additions to the related assets. Gain or loss on disposal of property and equipment, if any, is recognized in the consolidated statements of comprehensive income as the difference between the net sales proceeds and the carrying amount of the underlying asset. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Intangible assets Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets acquired through business combinations are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion, and are measured at fair value upon acquisition. Favorable leases from such business combination transactions are amortized over the remaining operating lease term. Reacquired rights represent the franchise right the Group previously granted to the acquiree through franchise agreements and are amortized over the next renewal date in the applicable agreement. Amortization is computed using the straight-line method over the following estimated useful lives: ​ ​ ​ Trademark 10 years or indefinite life Technology ​ 10 years Network rights ​ 10 years Purchased software ​ 5-10 years Favorable leases ​ the remaining lease term Reacquired rights ​ the remaining franchise term ​ The trademarks acquired in the acquisition of Argyle Group and Urban Hotel Group (Note 3) can be renewed without substantial obstacles. As a result, the useful life is determined to be indefinite. The Group evaluates the trademark at the end of each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Impairment is tested annually or more frequently if events or changes in circumstances indicate that it might be impaired. Business combinations The Group accounts for all business combinations under the purchase method in accordance with ASC 805, Business Combinations The determination and allocation of fair values to the identifiable net assets acquired, liabilities assumed and noncontrolling interest is based on various assumptions and valuation methodologies requiring considerable judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the acquiree’s current business model and industry comparisons. Although the Group believes that the assumptions applied in the determination are reasonable based on information available at the date of acquisition, actual results may differ from forecasted amounts and the differences could be material. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Goodwill Goodwill represents the excess of the cost of an acquisition over the fair value of the identifiable assets acquired less liabilities assumed of an acquired business. The Group’s goodwill at December 31, 2020 and 2021 was related to its acquisition of subsidiaries and business. The Group follows ASC subtopic 350-20, Intangibles-Goodwill and Other: Goodwill In accordance with ASC 350-20, the Group has assigned and assessed goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or one level below the operating segment. The Group has determined that it has one reporting unit. The Group has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20, Testing Goodwill for Impairment In 2020, the Group elected to choose to bypass the qualitative assessment and proceed directly to perform a quantitative test. In 2019 and 2021, the Group performed a qualitative assessment for its operating unit. No impairment was recorded during any of the presented periods. Impairment of long-lived assets The Group evaluates impairment of its long-lived assets to be held and used, including property and equipment, definite-lived intangible assets and other non-current assets, when events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable in accordance with ASC subtopic 360-10, Property, Plant and Equipment-Overall 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Revenue recognition Leased and operated hotel revenues Revenues from leased-and-operated hotels are primarily derived from hotel operations, including the rental of rooms and food and beverage sales. Each of these products and services represents an individual performance obligation and, in exchange for these services, the Group receives fixed amounts based on fixed rates or fixed standalone selling price. Revenue is recognized when rooms are occupied, and food and beverages are sold as the respective performance obligations are satisfied. Sublease rental revenues are derived from subleasing partial space of the leased-and-operated hotels to third-parties, which are recognized on a straight-line basis over the contractual lease term. The sublease rental revenue is recorded in leased-and-operated hotels revenue in the consolidated statements of comprehensive income amounted to RMB74,893,930, RMB77,676,665 and RMB74,689,226 (USD11,720,369) for the years ended December 31, 2019, 2020 and 2021, respectively. Franchise and managed hotel revenues The franchise and managed agreement contains the following promised services: ● Intellectual Property (“IP”) license grant the right to access the Group’s hotel system IP, including brand names. ● Pre-opening services include providing services (e.g., property design, leasehold improvement, construction project management, systems installation, personnel recruiting and training, etc.) to the franchisees to assist in preparing for the hotel opening. ● System maintenance services include providing standardization hotel property management system (PMS), central reservation system (CRS) and other internet related services. ● Hotel management services include providing day-to-day management services of the hotels for the franchisees. The promises to provide pre-opening services and system maintenance services are not distinct performance obligation because they are attendant to the license of IP. Therefore, the promises to provide pre-opening services and system maintenance services are combined with the license of IP to form a single performance obligation. Hotel management services forms a single distinct performance obligation. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Revenue recognition (continued) Franchise and managed hotel revenues (continued) Revenues from franchised-and-managed hotels are derived from franchise agreements where the franchisees are required to pay (i) an initial one-time non-refundable franchise fee, and (ii) continuing franchise fees, which mainly consist of on-going management and service fees based on a certain percentage of the room revenues of the franchised-and-managed hotels and central reservation system (“CRS”) usage fee based on a fixed rate per transaction. For franchised-and-managed hotels, the Group has a performance obligation to provide franchisees a license to its hotel system intellectual property for use of certain of its brand names. The one-time franchise fees are fixed consideration payable upon submission of a franchise application or renewal and are recognized on a straight-line basis over the initial or renewal term of the franchise agreements. The Group does not consider this advance consideration to include a significant financing component, since it is used to protect the Group from the franchisees failing to adequately complete some or all of its obligations under the contract. The continuing fees represent variable consideration, as the transaction price is based on a percentage of underlying service revenue is recognized by the franchisees’ operations. The Group recognizes continuing franchise fees on a monthly basis over the term of the agreement as those amounts become payable. In addition, the Group designates hotel managers to certain hotels and accounts for hotel manager fees related to the hotels under the franchise program as revenues. Pursuant to the franchise-and-management agreements, the Group charges the franchisees fixed hotel manager fees to compensate the Group for the franchised-and-managed hotel managers’ salaries, social welfare benefits and certain other out-of-pocket expenses as incurred. The hotel manager fee is recognized as revenue on a monthly basis. During the years ended December 31, 2019, 2020 and 2021, the hotel manager fees that were recognized as part of franchised-and-managed hotels revenue were RMB115,638,242, RMB112,729,886 and RMB131,027,473 (USD20,561,070), respectively. Other Revenues Other revenues are derived from selling of goods through the Company’s online mall and sale of hotel related products to franchisees. Revenues are recognized upon customers’ acceptance. Membership Program The Group invites its customers to participate in a membership program with four tiers of membership – E-membership, R-membership, gold membership and platinum membership. A one-time membership fee is charged for new members except for the E-membership. The membership automatically expires after two years in the event of non-usage and is automatically renewed if used at least once within a two-year period. Members enjoy discounts on room rates, priority in hotel reservation, and accumulate membership points for their paid stays, which can be redeemed for membership upgrades, room night awards and other gifts within two years after the points are earned. Membership fees from the Group’s membership program are earned and recognized on a straight-line basis over the expected membership duration of the different membership levels. Such duration is estimated based on the Group’s and management’s experience and is adjusted on a periodic basis to reflect changes in membership retention. The membership duration is estimated to be three 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Membership Program (continued) Membership points earned by members represent a material right to free or discounted goods or services in the future. The membership program has one performance obligation that consists of marketing and managing the program and arranging for award redemptions by members. The amount of revenue the Group recognize upon point redemption is impacted by the estimate of the “breakage” for points that members will never redeem, which amount were included in revenues from leased and operated hotel or revenues from franchised and managed hotels depending on the type of hotels the membership was sold at. The Group estimates breakage based on the Group’s historical experience and expectations of future member behavior and will true up the estimated breakage at end of each period. The Group recognized revenue net of reimbursement paid to franchisees as its performance obligation is to facilitate the transaction between the member and the franchised and managed hotels. PRC Value-Added Taxes and related tax surcharges Starting from May 2016, the accommodation services of the Group are subject to 6% of Value-Added Taxes. The Group is subject to education surtax and urban maintenance and construction tax, on the services provided in the PRC. Advertising and promotional expenses Advertising related expenses, including promotion expenses and production costs of marketing materials, are charged to the consolidated statements of comprehensive income as incurred, and amounted to RMB23,934,351, RMB38,934,867 and RMB22,906,044 (USD3,594,458) for the years ended December 31, 2019, 2020 and 2021, respectively. Government subsidies Government subsidies are received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. Such subsidies allow the Group full discretion to utilize the funds and are used by the Group for general corporate purposes. During the years ended December 31, 2019, 2020 and 2021, the Group received financial subsidies of RMB9,880,735, RMB20,094,745 and RMB16,993,539 (USD2,666,657), respectively, from various local PRC government authorities. There are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. Such amounts are recorded as other operating income when received as the amount of the subsidies and the timing of payment are determined solely at the discretion of the relevant government authorities and there is no assurance that the Group will continue to receive any or similar subsidies in the future. Interest income and other, net Interest income and other, net consists primarily of interest income, and to a much lesser extent foreign exchange gains or losses. Interest income is mainly generated from bank deposits and other interest earning financial assets and is recognized on an accrual basis using the effective interest method. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Leases Leases are classified as capital or operating leases. A lease that transfers to the lessee substantially all the benefits and risks incidental to ownership is classified as a capital lease. The Group did not have any leases that qualified as capital leases for the years ended December 31, 2020 and 2021. The Group leases hotel space under certain operating lease agreements. Certain of the lease agreements contain rent holidays and rent escalation provisions. Rent holidays and rent escalation provisions are considered in determining straight-line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the lease property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. The excess of rent expense and rent paid, as the case may be for respective leases, is recorded as deferred rent. Rental expenses amounted to RMB81,379,034, RMB122,590,230 and RMB238,493,602 (USD37,424,850) for the years ended December 31, 2019, 2020 and 2021, respectively. Income taxes Income taxes are provided for using the liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or change in tax status is recognized in income in the period the change in tax status occurs or the change in tax rates or tax law is enacted. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some or all of the deferred tax assets will not be realized. In accordance with ASC subtopic 740-10, Income Taxes, Overall The Group estimates its liability for unrecognized tax benefits which are periodically assessed and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expiration of the statute of limitations. The ultimate outcome for a particular tax position may not be determined with certainty prior to the conclusion of a tax audit or appeal or litigation process. The actual benefits ultimately realized may differ from the Group’s estimates. As each tax audit is concluded, adjustments, if any, are recorded in the Group’s financial statements. Additionally, in future periods, changes in facts, circumstances and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which the changes occur. The Group has elected to include interest and penalties related to an uncertain tax position in “income tax expense (benefit)” in the consolidated statements of comprehensive income. Foreign currency translation and transactions The reporting currency of the Group is the Renminbi (“RMB”). The functional currency of the Company, GreenTree Samoa, GreenTree Suites, PHI and the entities incorporated in Hong Kong is the United States dollar (“USD”). The financial records of PRC subsidiaries of the Company are maintained in the local currency, the Renminbi (“RMB”), which is their functional currency. ​ 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Foreign currency translation and transactions (continued) Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are re-measured into the applicable functional currencies at historical exchange rates. Transactions in currencies other than the applicable functional currencies during the year are converted into the functional currencies at the applicable rates of exchange prevailing on the transaction dates. Transaction gains and losses are recognized in “interest income and other, net” in the consolidated statements of comprehensive income. Assets and liabilities are translated into RMB at the exchange rate at the balance sheet date. Equity accounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive income (loss) in the consolidated statements of comprehensive income. Convenience translation Translations of amounts from RMB into U.S. dollars into U.S. dollars are solely for the convenience of the reader and were calculated at the noon buying rate of USD1 to RMB6.3726 on December 31, 2021, as set forth in H.10 statistical release of the Federal Reserve Board. The translation is not intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into U.S. dollars at that rate on December 31, 2021, or at any other rate. Fair value Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy 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. The Group follows ASC subtopic 820-10, Fair Value Measurements and Disclosures, which establishes a three-tier fair value hierarchy, and prioritizes the inputs used in measuring fair value as follows: 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 assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Fair value (continued) Assets and Liabilities Measured at Fair Value on a recurring basis Investments in equity securities with readily determinable fair values are measured using quoted market prices, and are recorded at fair values at each balance sheet date. The fair value of the Group’s Investments in wealth management products are measured using the income approach, based on quoted market interest rates of a similar instrument and other significant inputs derived from or corroborated by observable market data. The payable for contingent consideration and the returnable consideration from Urban Hotel Group are based on the achievement of certain financial targets in accordance with the acquisition agreements for the various periods. For the available-for-sale debt investment, the Group uses a combination of valuation methodologies, including income approach and Black-Scholes-Merton valuation model based on the Group’s best estimate, which is determined by using information including but not limited to the future cash flow forecast, discount rate, expected volatility, a discount for lack of marketability, the probability of exit events and the selection of comparable companies. The carrying values of other financial instruments, which consist of cash and cash equivalents, time deposits, accounts receivable, loans receivable, amounts due from related parties, accounts payable and amounts due to related parties are recorded at cost which ap

Business Combinations [Abstract]
Business Combinations	3. BUSINESS COMBINATIONS Business combinations in 2021: During the years ended 2021, the Group completed three business combinations. The total consideration amounted to RMB23,000,000 (USD3,609,202). The consideration paid is RMB19,530,000 (USD3,064,683). The results of the acquired hotel’s operation have been included in the Company’s consolidated financial statements since its respective dates of acquisition. The Group completed the valuations necessary to assess the fair value of the acquired assets and liabilities and the non-controlling interests (if applicable) with the assistance from an independent valuation firm, resulting from which the amounts of goodwill were determined and recognized as of the respective acquisition dates. Goodwill, which is non-deductible for tax purposes, is primarily attributable to the synergies expected to be achieved from the acquisitions. The initial accounting is incomplete as the valuations of intangible assets are provisional. The net revenue and net loss of the acquire included in the consolidated statements of operations for the year ended December 31, 2021 were not material. Neither the results of operations since the acquisition dates nor the pro forma results of operations of the acquirees were presented because the effects of these business combinations, individually and in the aggregate, were not significant to the Company’s consolidated results of operations. The following is a summary of the fair values of the aggregate assets acquired and liabilities assumed: ​ ​ ​ ​ ​ ​ ​ 2021 Amortization Period Property and equipment 92,075 10 years Intangible assets Trademark 36,896,000 10 years Goodwill 20,588,461 Noncontrolling interest (34,576,536) Total 23,000,000 ​ Business combinations in 2020: During the years ended 2020, the Group completed one business combinations of one hotel. The total consideration amounted to RMB2,200,000, among which RMB153,251 was allocated to goodwill. The business acquisition was accounted for under purchase accounting. The acquired hotel was considered insignificant. The results of the acquired hotel’s operation have been included in the Company’s consolidated financial statements since its respective dates of acquisition. Business combinations in 2019: During the years ended 2019, the Group completed four business combinations, including Argyle Group, Urban Hotel Group and other two companies. The results of the acquired entities’ operations have been included in the Company’s consolidated financial statements since their respective dates of acquisition. The Group completed the valuations necessary to assess the fair value of the acquired assets and liabilities and the non-controlling interests (if applicable) with the assistance from an independent valuation firm, resulting from which the amounts of goodwill were determined and recognized as of the respective acquisition dates. 3. BUSINESS COMBINATIONS (CONTINUED) Argyle Group On April 4, 2019, the Group completed the acquisition of Argyle Group through acquiring 60% equity interest in Argyle Beijing. Argyle Group is an owner and operator of hotels, with a network of mid-scale and up-scale brands in China and Southeast Asia. The total consideration amounted to RMB126,819,172, which was measured at the fair value of the 626,746 ordinary shares on the acquisition date and cash consideration of RMB65,779,032. The business acquisition was accounted for under purchase accounting. The net revenue and net loss of the acquire included in the consolidated statements of operations for the year ended December 31, 2019 were RMB11,882,976 and RMB7,694,834, respectively. The following is a summary of the fair values of the assets acquired and liabilities assumed: ​ ​ ​ ​ ​ ​ ​ 2019 Amortization Period Current assets 3,777,860 Property and equipment 1,013,378 3 - 17 years Intangible assets Purchased software 669,206 4 - 7 years Trademark 230,500,000 Indefinite life Goodwill 42,198,903 Current liabilities (7,618,079) Deferred tax liabilities (57,625,000) Non current liabilities (15,642,000) Noncontrolling interest (70,455,096) Total 126,819,172 ​ Urban Hotel Group On November 30, 2019, the Group completed the acquisition of Urban Hotel Group through acquiring 70% equity interest in Shandong Xinghui. Urban Hotel Group is a leading franchised hotel operator in China. The total consideration amounted to RMB 190,349,496, 3. BUSINESS COMBINATIONS (CONTINUED) Urban Hotel Group (continued) The following is a summary of the fair values of the assets acquired and liabilities assumed: ​ ​ ​ ​ ​ ​ ​ 2019 Amortization Period Current assets (i) 50,482,296 Property and equipment 6,913,189 3 - 10 years Intangible assets Favorable leases 20,100,000 Remaining lease terms Trademark 212,800,000 Indefinite life Purchased software 34,739 2 years Deferred tax assets 4,000,000 Other assets 4,537,000 Goodwill 49,037,577 Current liabilities (19,831,341) Non current liabilities (11,517,000) Deferred tax liabilities (58,225,000) Noncontrolling interest (67,981,964) Total 190,349,496 (i) Current assets acquired primarily included cash and cash equivalent of RMB 28,162,864 , other receivables of RMB 16,928,966 and accounts receivable of RMB 5,116,320 . Others On July 1, 2019, the Group completed the acquisition of a company at consideration of RMB37,255,016 On August 31, 2019, the Group completed the acquisition of one hotel at a cash consideration of RMB5,530,000. As the acquires are unlisted companies, the fair value measurements for the non-controlling interest and previously held equity interest are estimated with reference to the purchase price per share as of the acquisition date and adjustment for the lack of control and marketability. The business acquisitions were accounted for under purchase accounting. The assets and liabilities of these two acquirees were immaterial to the consolidated financial statements. The Group incurred transaction cost of RMB2,589,034 for the abovementioned four acquisitions, which was expensed and recorded in general and administrative expenses in the year ended December 31, 2019. The valuations used in the purchase price allocation described above were determined by the Company with the assistance of independent third-party valuation firms. The valuation reports considered generally accepted valuation methodologies such as the income, market and cost approaches. As the acquirees are all private companies, the fair value estimates of noncontrolling interests are based on significant inputs considered by market participants which mainly include (a) discount rate, (b) projected terminal value based on future cash flow (c) financial multiple of companies in the same industry and (d) adjustment for lack of control and marketability. 3. BUSINESS COMBINATIONS (CONTINUED) Others (continued) Goodwill was recognized as a result of expected synergies from combining operations of the Group and acquired business and other intangible assets that do not qualify for separate recognition. Goodwill is not amortized and is not deductible for tax purposes. In accordance with ASC 350, the Group assigned and assessed goodwill for impairment at the reporting unit level. All the acquired business has been integrated with the Group’s business. The Group concluded that it has only one reporting unit. Accordingly, goodwill is allocated to one single reporting unit.

LONG-TERM INVESTMENTS (Continued) Investment in Yibon In April 2017, the Group acquired a 30% interest in Yibon for cash consideration of RMB103,701,474 in form of capital injection into the target company. The terms of investment in 30% equity interest in the ordinary shares of Yibon includes a contingent redemption clause if certain specified criteria are not met.

As of December 31, 2020, the performance period had elapsed and the criterion had been determined to be not met, therefore the Group has the option to require Yibon to redeem the investment at the Group’s discretion. Therefore, the Group reclassified it to available-for-sale debt security and recorded it at its fair value. The holders of 70% of equity interest in Yibon had the right to exchange their equity interest in Yibon into the Company’s shares within a certain period after Yibon delivered an audited consolidated financial report for the year of 2019 in accordance with a formula using Yibon’s net profit achieved in the year of 2019 as calculation basis.

The incentive awards granted under the Share Incentive Plans typically have a maximum life of six years and vest in typical ways as vest ratably over the following four years starting after the first/second/third anniversary of the stated vesting commencement date. Share-based compensation expense of RMB26,490,395, RMB232,558 and RMB2,464,763 (USD386,775) was recognized in general and administrative expenses for the years ended December 31, 2019, 2020 and 2021. During the year ended December 31, 2019, 2020 and 2021, cash used to settle the related share-based compensation is nil, RMB1,186,271 and nil. For options granted during the years ended December 31, 2019 and 2021, the weighted-average grant date fair value for options granted was USD3.57 and USD2.42, respectively computed using the binomial option pricing model. The binomial model requires the input of subjective assumptions including the expected stock price volatility and the expected price multiple at which employees are likely to exercise stock options. The Group uses historical data to estimate forfeiture rate. Expected volatilities are based on the average volatility of the Group and comparable companies. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of share options was estimated using the following significant assumptions: ​ ​ ​ ​ ​ ​ ​ Granted in 2019 Granted in 2021 Risk-free interest rate 1.60%-2.60 % 0.92 % Volatility 35.66%-37.98 % 40 % Dividend yield 2.5 % 2.5 % Life of option 6 years 6 years ​ ​ The aggregate grant date fair value of the outstanding options was determined to be RMB39,628,188, RMB35,828,331 and RMB34,994,421 (USD5,491,388) as of December 31, 2019, 2020 and 2021, respectively and such amount shall be recognized as compensation expenses using the accelerate method for all employee share options granted. The total fair value of share options vested during the years ended December 31, 2019, 2020 and 2021 were RMB11,316,415, RMB8,610,259 and RMB8,319,569 (USD1,305,522). As of December 31, 2021, there was RMB592,966 (USD 93,049) in total unrecognized compensation expense related to unvested options, which is expected to be recognized over a weighted-average period of 0.37 years. 16.

SUBSEQUENT EVENTS On May 13, 2022, the Company announced that its board of directors has authorized a share repurchase program under which the Company may repurchase up to US$20 million worth of its outstanding (i) American depositary shares (“ADSs”), each representing one Class A ordinary share, and/or (ii) Class A ordinary shares over the next 12 months. Subsequent to December 31, 2021, the Group made new loans of RMB162million (USD25.4million) to GTI and its subsidiaries, and these companies repaid RMB42million (USD6.6million). As of May 16, 2022, amounts due from GTI and its subsidiaries amounted to RMB403.5 million (USD63.1 million), and the amount due to GTI was RMB3.7 million (USD0.6 million). On May 16, 2022, the Company entered into a definitive agreement (the “Sale and Purchase Agreement”) to acquire Da Niang Dumplings and Bellagio, two leading restaurant chain businesses in China (collectively, the “Target Businesses”), from GTI, the Company’s controlling shareholder, and a letter agreement (the “Letter Agreement”) in relation to the Sale and Purchase Agreement. Pursuant to the Sale and Purchase Agreement, the Company will acquire all of the issued and outstanding shares in Gen-Spring Limited, which at closing will own (i) all of the issued and outstanding equity interests in the Da Niang Dumplings business, and (ii) approximately 83.9% of the issued and outstanding equity interests in the Bellagio business, for an aggregate purchase price equal to the USD equivalent of RMB399.8 million (the “Proposed Acquisition”). Upon closing, GTI and its subsidiaries will fully settle all outstanding amounts due to the Company and from the Company aforementioned above in lieu of receiving consideration for the purchase price to be paid by the Company (“Consideration”). The board of directors of the Company formed a special committee (the “Special Committee”) consisting solely of independent directors to consider the Proposed Acquisition. With the assistance of its own independent financial and legal advisors, the Special Committee assessed the Proposed Acquisition and conducted arm's-length negotiations with GTI in relation to the Proposed Acquisition. The Special Committee has received from its independent financial advisor a written opinion to the effect that the Consideration is fair, from a financial point of view, to the Company. Acting upon the unanimous recommendation of the Special Committee, the board of directors approved the Proposed Acquisition. The closing of the Proposed Acquisition is subject to the satisfaction or waiver of customary closing conditions. Management and the directors of the Group have assessed that it is probable that the waiver of the above conditions will be obtained, and currently expects that the closing will occur in the second half of 2022. As the Group and the Target Businesses are under the common control of GTI before and after the Proposed Acquisition, management expects to account for the acquisition as a common control transaction in a manner similar to the pooling-of-interests method.

Summary of Principal Accounti_2

Summary of Principal Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation The consolidated financial statements of the Group have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”).
Basis of Consolidation	Basis of consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries and the consolidated VIEs for which the Company is the ultimate primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation. The Group evaluates its business activities and arrangements with the entities that operate the franchised-and-managed hotels to identify potential variable interest entities. Generally, these entities qualify for the business scope exception; therefore, consolidation is not appropriate under the variable interest entity consolidation guidance.
Variable Interest Entities	Variable Interest Entities The Group evaluates the need to consolidate certain variable interest entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. The Company is deemed as the primary beneficiary of and consolidates variable interest entities when the Company has the power to direct the activities that most significantly impact the economic success of the entities and effectively assumes the obligation to absorb losses and has the rights to receive benefits that are potentially significant to the entities.
Use of Estimates	Use of estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences could be material to the consolidated financial statements. The Group bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Significant accounting estimates reflected in the Group’s consolidated financial statements include allowance for doubtful accounts receivable, impairment of loans receivable, fair value measurement and impairment of investments, the useful lives and impairment of property and equipment and intangible assets, valuation allowance for deferred tax assets, impairment of goodwill, average life of memberships, estimates involved in the accounting for its membership program, contingent liabilities, purchase price allocation and share-based compensation arrangements.
Cash and Cash Equivalents	Cash and cash equivalents Cash and cash equivalents include cash on hand and demand deposits placed with commercial banks or other financial institutions and highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of three months or less. All cash and cash equivalents are unrestricted as to withdrawal and use.
Restricted Cash	Restricted cash Restricted cash comprise of deposits pledged with banks as security in relation to the guarantee for lease agreement and the guarantees for prepaid cards.
Long-term Time Deposits	Long-term time deposits Long-term time deposits comprise of deposits placed with certain bank with a maturity of one
Investments	Investments Short-term investments Short-term investments include time deposits with maturities of less than one year and investments in wealth management products, where certain deposits with variable interest rates or where principal amounts are not guaranteed, are placed with certain financial institutions. The Group accounts for short-term investments in debt in accordance with ASC topic 320, Investments—Debt Securities (“ASC 320”). The Group classifies the short-term investments in debt as “held-to-maturity”, “trading” or “available-for-sale”, whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at acquisition, for all categories of investments in securities, are included in earnings. Any realized gains or losses on the sale of the short-term investments, are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. The securities that the Group has the positive intent and the ability to hold to maturity are classified as held-to-maturity securities and stated at amortized cost. RMB80,000,000 (USD12,553,746) of which was pledged with banks as security in relation to the guarantee for the short-term bank loans and restricted to use (Note 11). Investments in equity securities The Group accounts for its investments in equity securities in accordance with ASC Subtopic 321, Investments – Equity Securities Long-term investments The Group’s long-term investments consist of equity-method investments, equity investments with and without readily determinable fair values and an available-for-sale debt investment. Investments in entities in which the Group 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 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Investments (continued) Long-term investments (continued) Investments in equity securities that have readily determinable fair values (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) are measured at fair value, with unrealized gains and losses from fair value changes recognized in net income in the consolidated statements of comprehensive income. The realized gains of RMB4,674,446, RMB4,746,032 and RMB1,564,892 (USD245,566) were recognized for the years ended December 31, 2019, 2020 and 2021, respectively. For the year ended December 31, 2019, there were unrealized gains of RMB6,473,358. For the year ended December 31, 2020 and 2021, there were unrealized losses of RMB9,247,254 and RMB14,058,448 (USD2,206,077) respectively. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The available-for-sale debt investment is convertible debt instruments issued by a private company that is redeemable at the Group’s option, which are measured at fair value. Interest income is recognized in earnings. All other changes in the carrying amount of these debt investments are recognized in other comprehensive income. An impairment loss on the available-for-sale debt investments, if any, is recognized in earnings when the decline in value is determined to be other-than-temporary. The interest income of nil, RMB18,667,117 and RMB544,352 (USD 85,421) was recognized in the earnings for the years ended December 31, 2019, 2020 and 2021, respectively. The fair value change of RMB2,791,663 (USD438,073) was recognized in the other comprehensive income during the year ended December 31, 2021. No impairment or significant fair value changes were recorded for these investments during any of other presented periods.
Accounts Receivable, Net of Allowance for Doubtful Accounts	Accounts receivable, net of allowance for doubtful accounts Trade receivables mainly consist of franchise fees receivable, rental amounts due from individual and corporate customers and travel agents, and sublease rental receivables due from third-party merchandisers, which are recognized and carried at the original invoice amounts less an allowance for doubtful accounts. The Group establishes an allowance for doubtful accounts primarily based on the age of the receivables and factors surrounding the credit risk of specific franchisees, customers, and merchandisers. Accounts receivable balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Inventories	Inventories Inventories mainly consist of small appliances, bedding and daily consumables. Small appliances and bedding are stated at cost, less accumulated amortization, and are amortized over their estimated useful lives, generally one year, from the time they are put into use. Daily consumables are expensed when used.
Loans Receivable	Loans receivable Loans receivable are carried at the original loan principal and accrued interest based on the contract rate, less an allowance for uncollectible accounts, as appropriate. The Group classified loans receivable as long-term or short-term investments according to their contractual maturity. The allowance for uncollectible accounts is estimated based on an assessment of the payment history, the existence of collateral, current information and events, and the facts and circumstances around the credit risk of the debtors. As of December 31, 2020 and 2021, all loans receivable which are past due are nonaccrual
Property and Equipment, Net	Property and equipment, net Property and equipment, net are stated at cost less accumulated depreciation and any recorded impairment. Depreciation of property and equipment is provided using the straight-line method over the following expected useful lives: ​ ​ ​ Leasehold improvements Over the shorter of the lease term or estimated useful lives Buildings ​ 20 years Furniture, fixtures and equipment ​ 3-5 years Motor vehicles ​ 5 years ​ Construction in progress represents leasehold improvements under construction or being installed and is stated at cost. Cost comprises original cost of property and equipment, installation, construction and other direct costs. Construction in progress is transferred to leasehold improvements and depreciation commences when the asset is ready for its intended use. Expenditures for repairs and maintenance are expensed as incurred, whereas the costs of betterments that extend the useful life of property and equipment are capitalized as additions to the related assets. Gain or loss on disposal of property and equipment, if any, is recognized in the consolidated statements of comprehensive income as the difference between the net sales proceeds and the carrying amount of the underlying asset.
Intangible Assets	Intangible assets Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets acquired through business combinations are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion, and are measured at fair value upon acquisition. Favorable leases from such business combination transactions are amortized over the remaining operating lease term. Reacquired rights represent the franchise right the Group previously granted to the acquiree through franchise agreements and are amortized over the next renewal date in the applicable agreement. Amortization is computed using the straight-line method over the following estimated useful lives: ​ ​ ​ Trademark 10 years or indefinite life Technology ​ 10 years Network rights ​ 10 years Purchased software ​ 5-10 years Favorable leases ​ the remaining lease term Reacquired rights ​ the remaining franchise term ​ The trademarks acquired in the acquisition of Argyle Group and Urban Hotel Group (Note 3) can be renewed without substantial obstacles. As a result, the useful life is determined to be indefinite. The Group evaluates the trademark at the end of each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Impairment is tested annually or more frequently if events or changes in circumstances indicate that it might be impaired.
Business Combinations	Business combinations The Group accounts for all business combinations under the purchase method in accordance with ASC 805, Business Combinations The determination and allocation of fair values to the identifiable net assets acquired, liabilities assumed and noncontrolling interest is based on various assumptions and valuation methodologies requiring considerable judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the acquiree’s current business model and industry comparisons. Although the Group believes that the assumptions applied in the determination are reasonable based on information available at the date of acquisition, actual results may differ from forecasted amounts and the differences could be material.
Goodwill	Goodwill Goodwill represents the excess of the cost of an acquisition over the fair value of the identifiable assets acquired less liabilities assumed of an acquired business. The Group’s goodwill at December 31, 2020 and 2021 was related to its acquisition of subsidiaries and business. The Group follows ASC subtopic 350-20, Intangibles-Goodwill and Other: Goodwill In accordance with ASC 350-20, the Group has assigned and assessed goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or one level below the operating segment. The Group has determined that it has one reporting unit. The Group has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20, Testing Goodwill for Impairment In 2020, the Group elected to choose to bypass the qualitative assessment and proceed directly to perform a quantitative test. In 2019 and 2021, the Group performed a qualitative assessment for its operating unit. No impairment was recorded during any of the presented periods.
Impairment of Long-lived Assets	Impairment of long-lived assets The Group evaluates impairment of its long-lived assets to be held and used, including property and equipment, definite-lived intangible assets and other non-current assets, when events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable in accordance with ASC subtopic 360-10, Property, Plant and Equipment-Overall
Revenue Recognition	Revenue recognition Leased and operated hotel revenues Revenues from leased-and-operated hotels are primarily derived from hotel operations, including the rental of rooms and food and beverage sales. Each of these products and services represents an individual performance obligation and, in exchange for these services, the Group receives fixed amounts based on fixed rates or fixed standalone selling price. Revenue is recognized when rooms are occupied, and food and beverages are sold as the respective performance obligations are satisfied. Sublease rental revenues are derived from subleasing partial space of the leased-and-operated hotels to third-parties, which are recognized on a straight-line basis over the contractual lease term. The sublease rental revenue is recorded in leased-and-operated hotels revenue in the consolidated statements of comprehensive income amounted to RMB74,893,930, RMB77,676,665 and RMB74,689,226 (USD11,720,369) for the years ended December 31, 2019, 2020 and 2021, respectively. Franchise and managed hotel revenues The franchise and managed agreement contains the following promised services: ● Intellectual Property (“IP”) license grant the right to access the Group’s hotel system IP, including brand names. ● Pre-opening services include providing services (e.g., property design, leasehold improvement, construction project management, systems installation, personnel recruiting and training, etc.) to the franchisees to assist in preparing for the hotel opening. ● System maintenance services include providing standardization hotel property management system (PMS), central reservation system (CRS) and other internet related services. ● Hotel management services include providing day-to-day management services of the hotels for the franchisees. The promises to provide pre-opening services and system maintenance services are not distinct performance obligation because they are attendant to the license of IP. Therefore, the promises to provide pre-opening services and system maintenance services are combined with the license of IP to form a single performance obligation. Hotel management services forms a single distinct performance obligation. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Revenue recognition (continued) Franchise and managed hotel revenues (continued) Revenues from franchised-and-managed hotels are derived from franchise agreements where the franchisees are required to pay (i) an initial one-time non-refundable franchise fee, and (ii) continuing franchise fees, which mainly consist of on-going management and service fees based on a certain percentage of the room revenues of the franchised-and-managed hotels and central reservation system (“CRS”) usage fee based on a fixed rate per transaction. For franchised-and-managed hotels, the Group has a performance obligation to provide franchisees a license to its hotel system intellectual property for use of certain of its brand names. The one-time franchise fees are fixed consideration payable upon submission of a franchise application or renewal and are recognized on a straight-line basis over the initial or renewal term of the franchise agreements. The Group does not consider this advance consideration to include a significant financing component, since it is used to protect the Group from the franchisees failing to adequately complete some or all of its obligations under the contract. The continuing fees represent variable consideration, as the transaction price is based on a percentage of underlying service revenue is recognized by the franchisees’ operations. The Group recognizes continuing franchise fees on a monthly basis over the term of the agreement as those amounts become payable. In addition, the Group designates hotel managers to certain hotels and accounts for hotel manager fees related to the hotels under the franchise program as revenues. Pursuant to the franchise-and-management agreements, the Group charges the franchisees fixed hotel manager fees to compensate the Group for the franchised-and-managed hotel managers’ salaries, social welfare benefits and certain other out-of-pocket expenses as incurred. The hotel manager fee is recognized as revenue on a monthly basis. During the years ended December 31, 2019, 2020 and 2021, the hotel manager fees that were recognized as part of franchised-and-managed hotels revenue were RMB115,638,242, RMB112,729,886 and RMB131,027,473 (USD20,561,070), respectively. Other Revenues Other revenues are derived from selling of goods through the Company’s online mall and sale of hotel related products to franchisees. Revenues are recognized upon customers’ acceptance.
Membership Program	Membership Program The Group invites its customers to participate in a membership program with four tiers of membership – E-membership, R-membership, gold membership and platinum membership. A one-time membership fee is charged for new members except for the E-membership. The membership automatically expires after two years in the event of non-usage and is automatically renewed if used at least once within a two-year period. Members enjoy discounts on room rates, priority in hotel reservation, and accumulate membership points for their paid stays, which can be redeemed for membership upgrades, room night awards and other gifts within two years after the points are earned. Membership fees from the Group’s membership program are earned and recognized on a straight-line basis over the expected membership duration of the different membership levels. Such duration is estimated based on the Group’s and management’s experience and is adjusted on a periodic basis to reflect changes in membership retention. The membership duration is estimated to be three 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Membership Program (continued) Membership points earned by members represent a material right to free or discounted goods or services in the future. The membership program has one performance obligation that consists of marketing and managing the program and arranging for award redemptions by members. The amount of revenue the Group recognize upon point redemption is impacted by the estimate of the “breakage” for points that members will never redeem, which amount were included in revenues from leased and operated hotel or revenues from franchised and managed hotels depending on the type of hotels the membership was sold at. The Group estimates breakage based on the Group’s historical experience and expectations of future member behavior and will true up the estimated breakage at end of each period. The Group recognized revenue net of reimbursement paid to franchisees as its performance obligation is to facilitate the transaction between the member and the franchised and managed hotels.
PRC Value-Added Taxes and Related Tax Surcharges	PRC Value-Added Taxes and related tax surcharges Starting from May 2016, the accommodation services of the Group are subject to 6% of Value-Added Taxes. The Group is subject to education surtax and urban maintenance and construction tax, on the services provided in the PRC.

Government Subsidies	Government subsidies Government subsidies are received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. Such subsidies allow the Group full discretion to utilize the funds and are used by the Group for general corporate purposes. During the years ended December 31, 2019, 2020 and 2021, the Group received financial subsidies of RMB9,880,735, RMB20,094,745 and RMB16,993,539 (USD2,666,657), respectively, from various local PRC government authorities. There are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. Such amounts are recorded as other operating income when received as the amount of the subsidies and the timing of payment are determined solely at the discretion of the relevant government authorities and there is no assurance that the Group will continue to receive any or similar subsidies in the future.
Interest Income and Other, Net	Interest income and other, net Interest income and other, net consists primarily of interest income, and to a much lesser extent foreign exchange gains or losses. Interest income is mainly generated from bank deposits and other interest earning financial assets and is recognized on an accrual basis using the effective interest method.
Leases	Leases Leases are classified as capital or operating leases. A lease that transfers to the lessee substantially all the benefits and risks incidental to ownership is classified as a capital lease. The Group did not have any leases that qualified as capital leases for the years ended December 31, 2020 and 2021. The Group leases hotel space under certain operating lease agreements. Certain of the lease agreements contain rent holidays and rent escalation provisions. Rent holidays and rent escalation provisions are considered in determining straight-line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the lease property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. The excess of rent expense and rent paid, as the case may be for respective leases, is recorded as deferred rent. Rental expenses amounted to RMB81,379,034, RMB122,590,230 and RMB238,493,602 (USD37,424,850) for the years ended December 31, 2019, 2020 and 2021, respectively.
Income Taxes	Income taxes Income taxes are provided for using the liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or change in tax status is recognized in income in the period the change in tax status occurs or the change in tax rates or tax law is enacted. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some or all of the deferred tax assets will not be realized. In accordance with ASC subtopic 740-10, Income Taxes, Overall The Group estimates its liability for unrecognized tax benefits which are periodically assessed and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expiration of the statute of limitations. The ultimate outcome for a particular tax position may not be determined with certainty prior to the conclusion of a tax audit or appeal or litigation process. The actual benefits ultimately realized may differ from the Group’s estimates. As each tax audit is concluded, adjustments, if any, are recorded in the Group’s financial statements. Additionally, in future periods, changes in facts, circumstances and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which the changes occur. The Group has elected to include interest and penalties related to an uncertain tax position in “income tax expense (benefit)” in the consolidated statements of comprehensive income.
Foreign Currency Translation and Transactions	Foreign currency translation and transactions The reporting currency of the Group is the Renminbi (“RMB”). The functional currency of the Company, GreenTree Samoa, GreenTree Suites, PHI and the entities incorporated in Hong Kong is the United States dollar (“USD”). The financial records of PRC subsidiaries of the Company are maintained in the local currency, the Renminbi (“RMB”), which is their functional currency. ​ 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Foreign currency translation and transactions (continued) Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are re-measured into the applicable functional currencies at historical exchange rates. Transactions in currencies other than the applicable functional currencies during the year are converted into the functional currencies at the applicable rates of exchange prevailing on the transaction dates. Transaction gains and losses are recognized in “interest income and other, net” in the consolidated statements of comprehensive income. Assets and liabilities are translated into RMB at the exchange rate at the balance sheet date. Equity accounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive income (loss) in the consolidated statements of comprehensive income.
Convenience Translation	Convenience translation Translations of amounts from RMB into U.S. dollars into U.S. dollars are solely for the convenience of the reader and were calculated at the noon buying rate of USD1 to RMB6.3726 on December 31, 2021, as set forth in H.10 statistical release of the Federal Reserve Board. The translation is not intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into U.S. dollars at that rate on December 31, 2021, or at any other rate.
Fair Value	Fair value Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy 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. The Group follows ASC subtopic 820-10, Fair Value Measurements and Disclosures, which establishes a three-tier fair value hierarchy, and prioritizes the inputs used in measuring fair value as follows: 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 assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Fair value (continued) Assets and Liabilities Measured at Fair Value on a recurring basis Investments in equity securities with readily determinable fair values are measured using quoted market prices, and are recorded at fair values at each balance sheet date. The fair value of the Group’s Investments in wealth management products are measured using the income approach, based on quoted market interest rates of a similar instrument and other significant inputs derived from or corroborated by observable market data. The payable for contingent consideration and the returnable consideration from Urban Hotel Group are based on the achievement of certain financial targets in accordance with the acquisition agreements for the various periods. For the available-for-sale debt investment, the Group uses a combination of valuation methodologies, including income approach and Black-Scholes-Merton valuation model based on the Group’s best estimate, which is determined by using information including but not limited to the future cash flow forecast, discount rate, expected volatility, a discount for lack of marketability, the probability of exit events and the selection of comparable companies. The carrying values of other financial instruments, which consist of cash and cash equivalents, time deposits, accounts receivable, loans receivable, amounts due from related parties, accounts payable and amounts due to related parties are recorded at cost which approximates their fair value due to the short-term nature of these instruments. The Group does not use derivative instruments to manage risks. ​ 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Fair value (continued) The following table summarizes the Company’s financial assets and liabilities measured and recorded at fair value as of December 31, 2020 and 2021 on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at Reporting Date Using ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ As of ​ Identical ​ Observable ​ Unobservable ​ ​ December 31, ​ Assets ​ Inputs ​ Inputs Description ​ 2020 (Level 1) (Level 2) (Level 3) Other assets Returnable consideration from acquisition of Urban Hotel Group 1,833,421 ​ ​ ​ 1,833,421 Short-term investments Investments in wealth management products 201,983,182 ​ ​ 201,983,182 ​ Investments in equity securities Equity securities with readily determinable fair value 242,378,696 242,378,696 ​ ​ Long-term investments ​ ​ Equity securities with readily determinable fair value 236,812,140 236,812,140 ​ ​ Available-for-sale debt investment 103,701,474 ​ ​ 103,701,474 ​ Accrued expenses and other current liabilities Payables for contingent consideration from acquisition of Urban Hotel Group 525,685 ​ ​ 525,685 ​ 787,234,598 479,190,836 201,983,182 106,060,580 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at Reporting Date Using ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ As of ​ Identical ​ Observable ​ Unobservable ​ ​ December 31, ​ Assets ​ Inputs ​ Inputs Description ​ 2021 ​ (Level 1) (Level 2) (Level 3) Other assets Returnable consideration from acquisition of Urban Hotel Group 5,385,583 ​ ​ ​ 5,385,583 Short-term investments ​ Investments in wealth management products 147,458,675 ​ ​ 147,458,675 ​ Investments in equity securities ​ Equity securities with readily determinable fair value 157,988,851 157,988,851 ​ ​ Long-term investments ​ ​ Equity securities with readily determinable fair value 39,852,428 39,852,428 ​ ​ Available-for-sale debt investment 106,493,137 ​ ​ ​ 106,493,137 ​ 457,178,674 197,841,279 147,458,675 111,878,720 ​ 2.

Comprehensive Income	Comprehensive income Comprehensive income is defined as the increase in equity of the Group during a year from transactions and other events and circumstances excluding transactions resulting from investments by owners and distributions to owners. Accumulated other comprehensive gain of the Group includes the foreign currency translation adjustments and unrealized gains on available-for-sale investments.
Comparative information	Comparative information Certain of the prior year comparative figures have been reclassified to conform to the current year’s presentation.
Segment Reporting	Segment reporting The Group operates and manages its business as a single segment. The Group’s chief operating decision maker has been identified as the CEO of the Group. The results of operations of the Group are regularly reviewed by the Chief Executive Officer on a consolidated basis. The Group primarily generates its revenues from customers in the PRC. Accordingly, no geographical segments are presented. Substantially all of the Group’s long-lived assets are located in the PRC.
Employee Benefits	Employee benefits The full-time employees of the Group’s PRC subsidiaries participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the PRC subsidiary of the Group to make contributions to the government for these benefits beyond the contribution made. The total amounts for such employee benefits, which were expensed as incurred, RMB28,700,397, RMB25,666,575 and RMB36,617,173 (USD5,746,033) for the years ended December 31, 2019, 2020 and 2021, respectively.
Share-based Compensation	Share-based compensation Share based awards granted to employees are accounted for under ASC 718, “Compensation—Stock Compensation”, which requires that such equity awards granted to employees be measured based on the grant date fair value and recognized as compensation expense a) immediately at grant date if no vesting conditions are required; or b) using accelerated method, net of estimated forfeitures, over the requisite service period, which is the vesting period.
Earnings Per Share	Earnings per share Class A and Class B ordinary shares have the same rights with regard to dividends and distributions upon liquidation of the Group. Net income is allocated on a pro rata basis to the Class A and Class B ordinary shares to the extent that each class shares in income for the period. Basic EPS for each class of ordinary shares is computed by dividing net income attributable to that class by the weighted average number of ordinary shares outstanding of that class for the period. Diluted earnings per share is calculated by dividing net income attributable to the Class A and Class B ordinary shares as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary share equivalents are excluded from the computation of diluted per share if their effects would be anti-dilutive. Contingently issuable shares relating to shares to be issued as a part of purchase consideration associated with business combinations, are included in the computation of basic earnings per share only when there is no circumstance under which those shares would not be issued. Contingently issuable shares are included in the denominator of the diluted EPS calculation as of the beginning of the period or as of the inception date of the contingent share arrangement, if later, only when dilutive and when all the necessary conditions have been satisfied as of the reporting period end.
Concentration of Credit Risk	Concentration of credit risk Financial instruments that potentially expose the Group to concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, amounts due from related and loans receivable. As of December 31, 2020, the Group had RMB434,229,811, RMB196,456,442, RMB185,772 and RMB1,183,983 held in cash and bank deposits by entity located in the Mainland China, Cayman Island, Hong Kong and Japan, respectively. As of December 31, 2021, the Group had RMB283,847,034 (USD44,541,794), RMB31,973,714 (USD5,017,373), RMB72,907 (USD11,441) and RMB1,722,251 (USD270,259) held in cash and bank deposits by entity located in the Mainland China, Cayman Island, Hong Kong and Japan, respectively. Management believes that these financial institutions are of high credit quality and continually monitors the credit worthiness of these financial institutions. The Group conducts credit evaluations on its customers and generally does not require collateral or other security from such customers. The Group periodically evaluates the creditworthiness of the existing customers in determining an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. The Group made loans to third-party individuals and related parties under loan agreements and is exposed to credit risk in case of defaults by the debtors. The maximum amount of loss due to credit risk is limited to the total outstanding principal plus accrued interest on the balance sheet date. As of December 31, 2020 and 2021, there were RMB394,948,617 and RMB965,475,805 (USD151,504,222) of loans receivable outstanding. The Group evaluates and monitors the credit worthiness of the debtors and records an allowance for uncollectible accounts based on an assessment of the payment history, the existence of collateral, current information and events, and the facts and circumstances around the credit risk of the debtor.
Currency Convertibility Risk	Currency Convertibility Risk Substantially all of the Group’s operating activities are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the People’s Bank of China or other banks authorized by the PRC government to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Foreign Currency Exchange Rate Risk	Foreign Currency Exchange Rate Risk The functional currency of the Company is USD, and the reporting currency is RMB. Since July 21, 2005, RMB has been permitted by the PRC government to fluctuate within a managed band against a basket of certain foreign currencies. The depreciation of the USD against the RMB was approximately 2.34% in 2021. Any significant revaluation of RMB may materially and adversely affect the cash flows, operating results and financial position of the Group. As a result, an appreciation of RMB against USD would result in foreign currency translation loss when translating the net assets of the Group from USD into RMB. For the years ended December 31, 2019 and 2020, the net foreign currency translation gain resulting from the translation from USD to RMB reporting currency recorded in other comprehensive income was RMB2,933,162, loss recorded RMB19,714,207, respectively. For the years ended December 31, 2021, the net foreign currency translation loss recorded RMB6,497,403 (USD1,019,584).
Recently Issued Accounting Pronouncements	Recently issued accounting pronouncements As a company with less than USD1.07 billion in revenue for the last fiscal year, the company qualifies as an “emerging growth company” pursuant to the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include a provision that an emerging growth company 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. The Company has adopted the extended transition period. Adopted Accounting Standards The Group adopted ASU No. 2018-13, Fair Value Measurement (Topic 820 ): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement ​ 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES (CONTINUED) Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases Leases Leases (Topic 842): Targeted Improvements Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842) The Group will adopt new leasing standard using the modified retrospective method and will not restate comparable periods. The Group will elect the package of practical expedients permitted under the transition guidance, which allow the Group to carry forward the historical lease classification, the assessment whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard. The Group will also elect the practical expedient not to separate lease and non-lease components for certain classes of underlying assets and the short-term lease exemption for contracts with lease terms of 12 months or less. Certain operating leases related to buildings and offices will be subject to ASU 2016-02 and right-of-use assets and lease liabilities will be recognized on the Group’s consolidated balance sheet. The Group currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Group’s balance sheet for certain in-scope operating leases. The Group does not expect any material impact on net assets and the consolidated statement of comprehensive income as a result of adopting the new standard. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses ​ 2.
