May I ask if I go to Taiwan, can I leave the airport if I transit in Hong Kong or Macau? Do I need a visa?

The Travel Permit for Traveling to and from Taiwan is not a passport, so it cannot be used as a document to stay in the urban area of ​​Macau.

You can leave the airport without a Hong Kong and Macau Pass and endorsement. This is how I went the year before last. When I arrived in Hong Kong, I just had to use the Taiwan Entry Permit and Pass, and when I left the customs, I filled out an entry card. The customs would put a small label on the visa page of the pass. Just keep that and the entry card. You can stay for 7 days, but you must keep the immigration card well, and it will be checked when you leave the country. Welcome to click the green "Accept as best answer", thank you

You can leave the airport without a visa. <br/><br/>Regulations on the entry and exit of non-Macao residents on the website of the Macao Public Security Police Force:<br/>Statutory exempt "visa" or "entry permit" persons:<br/>Holding "Mainland Residents "Taiwan Travel Permit" and "Taiwan Travel Permit" for mainlanders<br/>Duration of stay: up to 7 days (whether going to Taiwan via Macao or returning to the mainland from Macao)<br/><br/>Hong Kong also has similar regulations, so they are not listed up.
