Summary of Significant Accounting Policies [Abstract]

Principles of consolidation

The accompanying unaudited interim condensed consolidated financial statements of the Company include the financial statements of the Company and its subsidiaries, VIE and VIE’s subsidiaries for which the Company is the ultimate primary beneficiary.

A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power; has the power to appoint or remove the majority of the members of the board of directors (the “Board”); and to cast majority of votes at the meeting of the Board or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

All significant transactions and balances between the Company and its subsidiaries, VIE and VIE’s subsidiaries have been eliminated. The non-controlling interests in consolidated subsidiaries are shown separately in the unaudited interim condensed consolidated financial statements.

Foreign currency

The Company’s reporting currency is the Renminbi (“RMB”). The functional currency of the Company and its subsidiaries which are incorporated in Hong Kong (“HK”) is United States dollars (“US$”). The functional currencies of the other subsidiaries are their respective local currencies. The determination of the respective functional currency is based on the criteria set out by ASC 830, Foreign Currency Matters, (“ASC 830”).

Transactions denominated in currencies other than in the functional currency are translated into the functional currency using the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are translated into functional currency using the applicable exchange rates at the balance sheet date. Non-monetary items that are measured in terms of historical cost in foreign currency are re-measured using the exchange rates at the dates of the initial transactions. Exchange gains or losses arising from foreign currency transactions are included in the unaudited interim condensed consolidated statements of comprehensive income.

The financial statements of the Company’s entities of which the functional currency is not RMB are translated from their respective functional currency into RMB. Assets and liabilities denominated in foreign currencies are translated into RMB at the exchange rates at the balance sheet date. Equity accounts other than earnings generated in current period are translated into RMB at the appropriate historical rates. Income and expense items are translated into RMB using the periodic average exchange rates. The resulting foreign currency translation adjustments are recorded in other comprehensive income in the unaudited interim condensed consolidated statements of comprehensive income, and the accumulated foreign currency translation adjustments are presented as a component of accumulated other comprehensive income in the consolidated statements of shareholders’ equity.

Cash and cash equivalents

Cash and cash equivalents represent cash on hand, time deposits and highly-liquid investments placed with banks or other financial institutions, which are unrestricted as to withdrawal and use, and which have original maturities of three months or less.

Accounts receivable and allowance for credit losses

Accounts receivable are stated at the historical carrying amount net of allowance for credit losses.

The Company maintains an allowance for credit losses which reflects its best estimate of amounts that potentially will not be collected. The Company determines the allowance for credit losses taking into consideration various factors including but not limited to historical collection experience and credit-worthiness of the debtors as well as the age of the individual receivables balance. Additionally, the Company makes specific bad debt provisions based on any specific knowledge the Company has acquired that might indicate that an account is uncollectible. The facts and circumstances of each account may require the Company to use substantial judgment in assessing its collectability.

On January 1, 2023, the Company adopted ASC326, Financial Instruments-Credit Losses (“ASC326”), using modified-retrospective transition approach. Following the adoption of this guidance, a cumulative-effect adjustment in accumulated deficit of nil was recognized as of January 1, 2023. Pursuant to ASC 326, an allowance for credit losses for financial assets, including accounts receivable, carried at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on credit losses expected to arise over the life of the asset’s contractual term, which includes consideration of prepayments. Assets are written off when the Company determines that such financial assets are deemed uncollectible and are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously written off, not to exceed the aggregate of the amount previously written off, are included in determining the necessary reserve at the balance sheet date. The Company pools financial assets based on similar risk characteristics to estimate expected credit losses. The Company estimates expected credit losses on financial assets individually when those assets do not share similar risk characteristics. The Company closely monitors its accounts receivable including timely account reconciliations, detailed reviews of past due accounts, updated credit limits, and monthly analysis of the adequacy of their reserve for credit losses.

Property and equipment, net

Property and equipment are stated at cost less accumulated depreciation and impairment loss, if any. Property and equipment are depreciated at rates sufficient to write off their costs less impairment and residual value, if any, over their estimated useful lives on a straight-line basis. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets.

Category		Estimated useful life
Leasehold improvements		Shorter of the estimated useful life or remaining lease term
Computer and electronic equipment		3 – 5 years
Office equipment		3 – 5 years
Motor vehicles		5 years

Impairment of long-lived assets other than goodwill

Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount may not be fully recoverable or that the useful life is shorter than the Company had originally estimated. When these events occur, the Company evaluates the impairment by comparing carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Company recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. Impairment charge recognized for the six months ended June 30, 2025 and 2026 was nil.

Fair value of financial instruments

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Company considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability.

Accounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Accounting guidance establishes three levels of inputs that may be used to measure fair value:

		Level 1		Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

		Level 2		Other inputs that are directly or indirectly observable in the marketplace.

		Level 3		Unobservable inputs which are supported by little or no market activity.

Financial assets and liabilities of the Company primarily consist of cash and cash equivalents, short-term investments, accounts receivables, amounts due from related parties, accounts payables, amounts due to related parties, accrued expenses and other liabilities excluding payroll and welfare payables. As of December 31, 2025 and June 30, 2026, the carrying values of these financial assets and liabilities approximate their fair values.

The following table summarizes the carrying values of the Company’s financial instruments that the management believes should be categorized as Level 2:

Cost of revenues

Costs of revenues primarily consist of staff costs, digital educational content costs, inventory cost and other direct costs of providing these services or goods.

Research and development expenses

Research and development costs are expensed as incurred. These costs primarily consist of payroll and related expenses for personnel engaged in research and development activities.

Government subsidy

Government subsidy represent cash subsidies received from the PRC government. Cash subsidies that have no defined rules and regulations to govern the criteria necessary for companies to enjoy the benefits are recognized when received. Such subsidies are generally provided as incentives from the local government to encourage the expansion of local business.

Comprehensive income

The Company applies ASC 220, Comprehensive Income (“ASC 220”), with respect to reporting and presentation of comprehensive income and its components in a full set of financial statements. Comprehensive income is defined to include all changes in equity of the Company during a period arising from transactions and other event and circumstances except those resulting from investments by shareholders and distributions to shareholders. For the years presented, the Company’s comprehensive income includes net income and other comprehensive income, which mainly consists of the foreign currency translation adjustment that have been excluded from the determination of net income.

Share-based compensation

The Company applies ASC 718 (“ASC 718”), “Compensation — Stock Compensation,” to account for its employee share-based payments. In accordance with ASC 718, the Company determines whether an award should be classified and accounted for as a liability award or an equity award, and all of its share-based awards to employees have been classified as equity awards. The cost of these awards is measured based on the fair value at the grant date. The related compensation expense is recognized using an accelerated method over the requisite service period, which generally corresponds to the vesting period. For awards where no future service is required, the cost is expensed immediately on the grant date.

Earnings (loss) per share

Net income (loss) is not allocated to other participating securities if based on their contractual terms they are not obligated to share the income. Basic earnings per share is computed by dividing net income attributable to ordinary shareholders by the weighted-average number of ordinary equivalent shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to ordinary shareholders, as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the year. Ordinary equivalent shares consist of ordinary shares issuable upon the exercise of share options using the treasury stock method.

Statutory reserve

Pursuant to the laws applicable to the PRC, PRC entities must make appropriations from their after-tax profit to the non-distributable “statutory surplus reserve fund.” Subject to certain cumulative limits, the “statutory surplus reserve fund” requires annual appropriations of 10% of after-tax profit until the aggregated appropriations reach 50% of the registered capital (as determined under accounting principles generally accepted in the PRC (“PRC GAAP”) at each year-end). For foreign invested enterprises and joint ventures in the PRC, annual appropriations should be made to the “reserve fund.” For foreign invested enterprises, the annual appropriation for the “reserve fund” cannot be less than 10% of after-tax profits until the aggregated appropriations reach 50% of the registered capital (as determined under PRC GAAP at each year-end). If the Company has accumulated loss from prior periods, the Company is able to use the current period net income after tax to offset against the accumulate loss.

Commitments and Contingencies

In the normal course of business, the Company is subject to contingencies, including legal proceedings and claims arising out of the business that relate to a wide range of matters, such as government investigations and tax matters. The Company recognizes a liability for such contingency if it determines it is probable that a loss has occurred and a reasonable estimate of the loss can be made. The Company may consider many factors in making these assessments including historical performance and the specific facts and circumstances of each matter.

Recent accounting pronouncements

The Company is an emerging growth company (‘‘EGC’’) as defined by the Jumpstart Our Business Startups Act (‘‘JOBS Act’’). The JOBS Act provides that an EGC can take advantage of extended transition periods for complying with new or revised accounting standards. This allows an EGC to delay adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to take advantage of the extended transition periods. However, this election will not apply should the Company cease to be classified as an EGC.

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which enhances the transparency of income tax disclosures. The amendments in ASU 2023-09 requires (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 on a prospective basis, with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating ASU 2023-09 to determine the impact it may have on its consolidated financial statements disclosures.

In November 2024, the FASB issued ASU 2024-03, “Reporting Comprehensive Income — Expense Disaggregation Disclosures”, which focuses on improving the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard and does not expect that the adoption of this guidance will have a material impact on its financial position, results of operations and cash flows.

In January 2025, the FASB issued ASU 2025-01, “Income Statement – Comprehensive Income – Expense Disaggregation Disclosure (Subtopic 220-40): Clarifying the Effective Date.” This pronouncement revises the effective date of ASU 2024-03 and clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Entities within the ASU’s scope are permitted to early adopt the accounting standard update. The Company is currently evaluating these new disclosure requirements and does not expect the adoption to have a material impact.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments provide a practical expedient and, if applicable, an accounting policy election to simplify the measurement of credit losses for certain receivables and contract assets. The amendments are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in any interim or annual period in which financial statements have not yet been issued or made available for issuance. The Company is currently evaluating the potential impact of ASU 2025-05 on its condensed consolidated financial statements and disclosures.

In December 2025, the FASB issued ASU 2025-11, which is intended to improve the navigability of the guidance in ASC 270 and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. The ASU also addresses the form and content of such financial statements, adds lists to ASC 270 of the interim disclosures required by all other Codification topics, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. As the Board stated in the proposed guidance and reiterates in the ASU, the amendments are not intended to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements. For public business entities, the amendments in ASU 2025-11 are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. For entities other than public business entities, for interim reporting periods within annual reporting periods beginning after December 15, 2028. Early adoption is permitted for all entities. The Company is currently evaluating these new disclosure requirements and does not expect the adoption to have a material impact.

In December 2025, the FASB issued ASU 2025-12, which is to correct, clarify, and otherwise improve U.S. GAAP. ASU 2025-12 includes 33 improvements that span a wide range of topics, including Clarifying diluted earnings per share (EPS) calculation when a loss from continuing operations exists, Clarifying disclosure requirements for lease receivables from sales-type or direct financing leases, Revising the calculation of the reference amount for beneficial interests to prevent double counting credit losses, Clarifying the permissible methods to account for treasury stock retirements, and Clarifying the guidance for transfers of receivables from contracts with customers. The amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. If an entity adopts the amendments in this Update in an interim period, it must adopt them as of the beginning of the annual reporting period that includes that interim reporting period. An entity may elect to early adopt the amendments on an issue-by-issue basis. For example, an entity may decide to early adopt certain amendments and adopt the remaining amendments at the effective date. An entity should apply the amendments in this Update (except for the amendments to Topic 260, Earnings Per Share, related to Issue 4) using one of the following transition methods: (i) Prospectively to all transactions recognized on or after the date that the entity first applies the amendments, or (ii) Retrospectively to the beginning of the earliest comparative period presented. An entity should adjust the opening balance of retained earnings (or other appropriate components of equity or net assets in the statement of financial position) as of the beginning of the earliest comparative period presented. The Company is currently evaluating these new disclosure requirements and does not expect the adoption to have a material impact.

Except as mentioned above, the Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated balance sheets, condensed consolidated statements of operations and comprehensive income (loss) and condensed consolidated statements of cash flows.
