The majority of the WFOE, the VIE and VIE’s subsidiaries’ contracts have one single performance obligation as the promise to transfer the individual goods is not separately identifiable from other promises in the contracts and are, therefore, not distinct. The revenue streams are recognized at a point in time when title and risk of loss passes and the customer accepts the goods, which generally occurs at delivery. The WFOE, the VIE and VIE’s subsidiaries’ products are sold with no right of return and the WFOE, the VIE and VIE’s subsidiaries do not provide other credits or sales incentives, which would be accounted for as variable consideration. Sales taxes invoiced to customers and remitted to government authorities are excluded from net sales.
The contract liabilities are recorded on the consolidated balance sheets as advance from customers as of September 30, 2022 and September 30, 2021.
Refer to Note 15 for disaggregated revenue information.
Government Grants
Government grants are recognized when there is reasonable assurance that the attached conditions will be complied with. When the grant relates to an expense item, it is net against the expense and recognized in the consolidated statements of operations and comprehensive income over the period necessary to match the grant on a systematic basis to the related costs. Where the grant relates to an asset acquisition, it is recognized in the consolidated statements of operations and comprehensive income in proportion to the useful life of the related assets. Government grants received for the year ended September 30, 2022, 2021 and 2020 were $76,299, $152,265, and $764,962, respectively. Grant income recognized for the year ended September 30, 2022, 2021 and 2020 were $352,262, $559,828 and $1,079,200, respectively, included in other income within the consolidated statements of operations and comprehensive income. As of September 30, 2022 and 2021, the deferred government grants were $431,485 and $755,312, respectively. The weighted average remaining periods for the government grant to be recognized were 3.96 years and 4.15 years, respectively.
Research and Development Expenses

For the year ended September 30, 2022, 2021 and 2020, total research and development expense were approximately $1,224,344, $8,000 and $54,000, respectively, which were recorded in general and administrative expenses in the consolidated statements of operations and comprehensive income.

The Company incurred $166,064, $118,020 and $2,488 of advertising costs during the years ended September 30, 2022, 2021 and 2020, respectively. Advertising costs consist primarily of online marketing costs, such as advertising on social networking sites and e-mail marketing campaigns.
Income Taxes
The Company, its subsidiaries, the VIE and VIE’s subsidiaries account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company, its subsidiaries, the VIE and VIE’s subsidiaries determine deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
The Company, its subsidiaries, the VIE and VIE’s subsidiaries recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, the Company, its subsidiaries, the VIE and VIE’s subsidiaries consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company, its subsidiaries, the VIE and VIE’s subsidiaries determine that they would be able to realize the deferred tax assets in the future in excess of their net recorded amount, they would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
