Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of preparation The unaudited consolidated financial statements of the Company have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for the complete consolidated financial statements. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments as necessary for the fair statement of the Company’s financial position as of June 30, 2024, results of operations and cash flows for the six months ended June 30, 2023 and 2024. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related footnotes thereto contained in the Company’s most recent consolidated annual financial statements filed with the SEC on Form 20 -F Use of estimates The preparation of the Company’s unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s unaudited consolidated financial statements include, but not limited to, inventory write -down -lived -based Principles of consolidation The Company’s unaudited consolidated financial statements include the financial statements of the Company and its subsidiaries. All transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation. Functional currency and foreign currency translation The Company uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of PRC is the United States dollar (“US$”), while the functional currency of the PRC entities in the Company is RMB as determined based on the criteria of ASC 830, “ Foreign Currency Matters” Transactions denominated in other than the functional currencies are re -measured -measured The financial statements of the Company are translated from the functional currency to the reporting currency, RMB. Assets and liabilities of the Company and its subsidiaries incorporated outside of PRC are translated into RMB at fiscal year -end Convenience translation The United States dollar (“US$”) amounts disclosed in the accompanying financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ were calculated at the rate of US$1.00=RMB7.1268 on June 30, 2024, representing the central parity rate on June 30, 2024 published by the People’s Bank of China. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on June 30, 2024, or at any other rate. Concentration of credit risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents with financial institutions with high credit ratings and quality. Fair value measurement The Company adopted the guidance of Accounting Standards Codification (“ASC”) 820 for fair value measurements which clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Observable, market -based Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. ASC 820 also describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. Financial instruments included in current assets and current liabilities are reported in the unaudited consolidated balance sheets at face value or cost, which approximate to fair value because of their short -term Related party transactions Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operational decisions. Parties are also considered to be related if they are subject to common control or common significant influence. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities. Transactions involving related parties cannot be presumed to be carried out on an arm’s -length -length Cash and cash equivalents Cash and cash equivalents include cash in bank and time deposits placed with banks or other financial institutions, which have original maturities of three months or less and are readily convertible to known amounts of cash. As of December 31, 2023 and June 30, 2024, cash and cash equivalents in banks was RMB48,164,664 and RMB23,506,562, respectively. Restricted cash Restricted cash mainly represents the bank deposit frozen by the court as a result of legal proceedings. As of December 31, 2023 and June 30, 2024, the Company had restricted cash balance of RMB417,990 and RMB418,201, respectively. Inventories, net Inventories, consist of raw materials, work in process and finished goods. Inventories are stated at the lower of cost and net realizable value. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventory to the estimated net realizable value due to slow -moving Prepayments Prepayments primarily consist of advances to suppliers for future inventory purchases and prepaid processing fees. Property, plant and equipment, net Property, plant and equipment are stated at historical cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated using the straight -line Computers and electronic equipment 2 to 3 years Office furniture 5 years Transportation equipment 4 years Buildings 20 years Leasehold improvements are depreciated using the straight -line Construction in progress represents assets under construction. All direct costs relating to the construction are capitalized as construction in progress. Construction in progress is not depreciated until the asset is placed in service. Intangible asset, net The Company’s intangible asset with definite useful lives primarily consists of a franchise right and land use right. According to the law of PRC, the government owns all the land in the PRC. Companies or individuals are authorized to possess and use the land only through land use rights granted by the Chinese government for a specified period of time. The Company amortizes its franchise right and land use right on a straight -line Franchise right 2 years Land use right 50 years Impairment of long-lived assets For long -lived -of-use no -lived Revenue from contracts with customers Consistent with the criteria of ASC 606 “Revenue from Contracts with Customers”, the Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services.

The Company elected to account for shipping and handling fees as a fulfillment cost. The product sales contracts generally include product warranty provisions. The Company did not accrue warranty liabilities for the product sales as the financial impacts of the warranty have historically been and are expected to continue to be immaterial. The Company estimates sales return based on historical experiences and there was no allowance for sales return recorded during the six months ended June 30, 2023 and 2024. Service revenue The Company also generates revenue from its design and technical services under separate contracts. Revenues from the design and technical service to the customers are recognized at a point in time when services are provided. Revenue disaggregation In accordance with ASC 606, the Company disaggregates revenue from contracts with customers by revenue stream. The Company determined that disaggregating revenue into these categories meets the disclosure objective in ASC 606 which is to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors. The following table summarizes the net revenues generated from different revenue streams: For the six months ended June 30, 2023 2024 (Unaudited) (Unaudited) RMB RMB Product sales revenue 46,868,172 20,352,715 Service revenue 5,400,544 4,386,765 Net revenues 52,268,716 24,739,480 Contract liabilities Contract liabilities are recorded when consideration is received from a customer prior to transferring the control of goods or services to the customer.

The Company recognizes research and development expenses as expense when incurred. Leases Right -of-use -of-use The Company elected not to record assets and liabilities on its unaudited consolidated balance sheet for lease arrangements with terms of 12 months or less. The Company recognizes lease expenses for such leases on a straight -line Employee social security and welfare benefits Employees of the Company in the PRC are entitled to staff welfare benefits including pension, work -related -mandated -employer The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Company’s obligations are limited to the amounts contributed and no legal obligation beyond the contributions made. Share-based compensation Restricted shares and options granted to employees and directors are accounted for under ASC Topic 718, “Compensation — Stock compensation” (“ASC 718”). In accordance with ASC 718, the Company determines whether restricted shares or options should be classified and accounted for as an equity award. All grants of restricted shares and options to employees and directors classified as equity awards are recognized in the financial statements based on their grant date fair values. The value of the portion of the award that is ultimately expected to vest is recognized as compensation expense over the requisite service periods in the statements of operations. In addition, compensation expense must be recognized for the change in fair value of any awards modified, repurchased or cancelled after the grant date. The fair value of stock options granted is estimated on the grant date using the Binomial or Black -Scholes Income taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the tax income rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that some portion or all of the deferred income tax assets will not be realized in the foreseeable future. In accordance with the provisions of ASC 740, “Income taxes”, the Company recognizes in its financial statements the impact of a tax position if a tax return position or future tax position is “more likely than not” to be sustained upon examination based solely on the technical merits of the position. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement.

Earnings (loss) per share The Company computes earnings (loss) per share in accordance with ASC 260, “Earnings per Share”. ASC 260 requires companies to present basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalents shares outstanding during the period. Dilutive equivalent shares are excluded from the computation of diluted earnings (loss) per share if their effects would be anti -dilutive -based Segment Reporting The Company uses the “management approach” in determining reportable segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s chief operating decision maker has been identified as the chief executive officer of the Company who reviews financial information of operating segments based on U.S. GAAP.
