Ask for help and use your passport to go from Hongkong to Taiwan Province Province.

Mainland citizens (mainland residents) are required to hold the Pass for Mainland Residents to and from Taiwan issued by the mainland and sign the endorsement of the Pass. You also need an entry permit issued by the Taiwan Province Provincial Immigration Bureau. Only when these two certificates are complete can you go to Taiwan Province Province. These two certificates are complete, and you can transfer from Hong Kong to Taiwan Province Province, and you can stay in Hong Kong for 7 days during the transfer.

Note: In some airports, you need to check whether you have a return ticket. There is no city in Chinese mainland where Taiwan Province Province can travel freely. Please consult the local public security exit-entry administration separately.
