I set up a Hong Kong company. How to do accounts in finance?

Accounting in Hong Kong is somewhat different from that in mainland companies. The mainland needs to make an accounting declaration once a month, and Hong Kong does it once a year. The first time may be when the company was established 18 months ago. The audit report only provides the company's financial data to the tax bureau, but this is not a tax return. The declaration needs to get a tax bill from the tax bureau, fill it out and submit it to the tax bureau, which is regarded as the completion of the declaration, but the time when the tax bureau issues the tax bill is not the same.
