Foreign Currency Transactions and Translations Policy [Policy Text Block]

d)

Foreign currency translation and transactions

The Company conducts substantially all of its operations through its PRC operating subsidiaries and VIEs, PRC is the primary economic environment in which the Company operates. For financial reporting purposes, the financial statements of the Company’s PRC operating subsidiaries and VIEs, which are prepared using the functional currency of the PRC, Renminbi (“RMB”), are translated into the Company’s reporting currency, the United States Dollar (“U.S. dollar”). Assets and liabilities are translated using the exchange rate at each balance sheet date. Revenue and expenses are translated using average rates prevailing during each reporting period, and stockholders’ equity is translated at historical exchange rates. Adjustments resulting from the translation are recorded as a separate component of accumulated other comprehensive income in stockholders’ equity.

Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the dates of the transactions. The resulting exchange differences are included in the determination of net loss of the consolidated statements of operations and comprehensive loss for the respective periods.

The exchange rates used to translate amounts in RMB into US$ for the purposes of preparing the consolidated financial statements are as follows:

	As of December 31,
	2022		2021

Balance sheet items, except for equity accounts		6.9646		6.3757

	Year Ended December 31,
	2022		2021

Items in the statements of operations and comprehensive loss		6.7261		6.4515

No representation is made that the RMB amounts could have been or could be converted into US$ at the above rates.

Accounts Receivable [Policy Text Block]

f)

Accounts receivable, net

Accounts receivable are recorded at net realizable value consisting of the carrying amount less an allowance for uncollectible accounts as needed. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on aging data, historical collection experience, customer specific facts and economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company did not have any off-balance-sheet credit exposure relating to its customers, suppliers or others. For the year ended December 31, 2022, the Company recorded approximately US$1.76 million of allowance for doubtful accounts against its accounts receivable. For the year ended December 31, 2021, the Company did not provide any allowance for doubtful accounts against its accounts receivable.

Property, Plant and Equipment, Policy [Policy Text Block]

h)

Property and equipment, net

Property and equipment are recorded at cost less accumulated depreciation/amortization. Depreciation/amortization is calculated on the straight-line method after taking into account their respective estimated residual values over the following estimated useful lives:

Leasehold improvements (years)	3
Vehicles (years)	5
Office equipment (years)	3	-	5
Electronic devices (years)	5

Depreciation/amortization expenses of fixed assets are included in sales and marketing expenses, general and administrative expenses and research and development expenses. Leasehold improvements are amortized over the lesser of the lease term or estimated useful life.

When property and equipment are retired or otherwise disposed of, resulting gain or loss is included in net income or loss in the period of disposition. Maintenance and repairs which do not improve or extend the expected useful lives of the assets are charged to expenses as incurred, whereas the cost of renewals and betterments that extend the useful life of the assets are capitalized as additions to the related assets.

Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]

j)

Impairment of long-lived assets

In accordance with ASC 360-10-35, long-lived assets, which include tangible long-lived assets and intangible long-lived assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recognized for the difference between the carrying amount of the asset and its fair value.

For the year ended December 31, 2022, the Company recorded aggregately US$2.12 million impairment loss associated with its intangible assets. For the year ended December 31, 2021, the Company did not record any impairment loss associated with its long-lived assets.

Stockholders' Equity, Policy [Policy Text Block]

l)

Reverse stock split

The Board of Directors of the Company approved a reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.001 per share (the “Common Stock”) at a ratio of 1-for-5 (the “Reverse Stock Split”). The Reverse Stock Split became effective on January 18, 2023 (the “Effective Date”). As a result, the number of shares of the Company’s authorized Common Stock was reduced from 100,000,000 shares to 20,000,000 shares and the issued and outstanding number of shares of the Common Stock was correspondingly decreased. The Reverse Stock Split has no effect on the par value of the Company’s Common Stock or authorized shares of preferred stock.

When the Reverse Stock Split became effective, each five shares of issued and outstanding Common Stock were automatically converted into one newly issued and outstanding share of Common Stock. No fractional shares were issued in connection with the Reverse Stock Split. Any fractional shares of Common Stock that would have otherwise resulted from the Reverse Stock Split were rounded up to the nearest full share. No cash or other consideration was paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split.

As a result of the Reverse Stock Split, 35,827,677 shares of Common Stock that were issued and outstanding at January 18, 2023 was reduced to 7,174,506 shares of Common Stock (taking into account the rounding of fractional shares).

Except where otherwise specified, all number of shares, number of warrants, share prices, exercise prices and per share data in the consolidated financial statements and notes to the consolidated financial statements have been retroactively restated as if the Reverse Stock Split occurred at the beginning of the periods presented.

Cost of Goods and Service [Policy Text Block]

n)

Cost of revenues

Cost of revenues primarily includes the cost of Internet and other forms of advertising resources and related technical services purchased from third parties, amortization of software platform development cost and other direct cost associated with providing services.

Lessee, Leases [Policy Text Block]

p)

Lease

The Company leases office spaces from unrelated parties in its normal course of business. Other than these office spaces lease contracts, the Company does not have any other contract that is or contains a lease under ASC Topic 842.

The Company’s lease contracts do not contain any option for the Company to extend or terminate the lease, and do not contain the option for the Company to purchase the underlying assets. Based on the noncancelable lease period in the contract, the Company considers contract-based, asset-based, market-based and entity-based factors to determine the term over which it is reasonably certain to extend the lease, and then determine the lease term of each contract, which is 1-8 years. The Company’s lease contracts only contain fixed lease payments and do not contain any residual value guarantee.

The Company’s office lease contracts do not contain any nonlease component and are classified as operating leases in accordance with ASC Topic 842-10-25-3.

For lease contracts with a duration of twelve months or less and thus met the definition of a short-term lease under ASC 842, the Company, in accordance with ASC 842-20-25-2, elected not to apply the recognition requirements (i.e. not to recognize right-of-use asset and related lease liability) to these short-term leases. Instead, the Company recognized the lease payments of these short-term leases in its consolidated statements of operations and comprehensive loss on a straight-line basis over the lease term. As of December 31, 2022 and 2021, lease payments liability related to these short-term leases was approximately US$0.10 million and US$0.15 million, respectively.

For lease contracts with a duration of over twelve months, as the implicit rates of the Company leases cannot be readily determined, in accordance with ASC Topic 842-20-30-3, the Company used its incremental borrowing rate as the discount rate to determine the present value of the lease payments for each lease contract. The Company’s incremental borrowing rate was determined based on the interest rate expected to be used by the commercial banks in the PRC for long-term loans with the same maturity terms as the respective lease contracts at lease inception, if lent to the Company on a collateralized basis.

As of December 31, 2022, operating lease right-of-use assets and total operating lease liabilities recognized was approximately US$1.76 million and US$1.88 million, respectively.

Income Tax Uncertainties, Policy [Policy Text Block]

r)

Uncertain tax positions

The Company follows the guidance of ASC Topic 740 “Income taxes”, which prescribes a more likely than not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As a result, the impact of an uncertain income tax position is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.

The Company recognizes interest on non-payment of income taxes under requirement by tax law and penalties associated with tax positions when a tax position does not meet the minimum statutory threshold to avoid payment of penalties. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes. The tax returns of the Company and its subsidiaries and VIEs are subject to examination by the relevant local tax authorities. The statute of limitations related to these tax returns under different circumstances various from 3-10 years, and for PRC entities, there is no statute of limitation in the case of tax evasion. The Company did not have any material interest or penalties associated with tax positions for the years ended December 31, 2022 and 2021 and did not have any significant unrecognized uncertain tax positions as of December 31, 2022 or 2021.

Comprehensive Income, Policy [Policy Text Block]

t)

Comprehensive income (loss)

The Company accounts for comprehensive income (loss) in accordance with ASC Topic 220 “Comprehensive Income”, which establishes standards for reporting and displaying comprehensive income (loss) and its components in the consolidated financial statements. Comprehensive income (loss) is defined as the change in equity of a company during a period from transactions and other events and circumstances excluding transactions resulting from investments from owners and distributions to owners. Accumulated other comprehensive income, as presented in the Company’s consolidated balance sheets are the cumulative foreign currency translation adjustments.

Commitments and Contingencies, Policy [Policy Text Block]

v)

Commitments and contingencies

The Company adopts ASC Topic 450 “Contingencies” subtopic 20, in determining its accruals and disclosures with respect to loss contingencies. Accordingly, estimated losses from loss contingencies are accrued by a charge to income when information available before financial statements are issued or are available to be issued indicates that it is probable that an asset had been impaired, or a liability had been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred.
