From Hong Kong to Macau on August 28th, stay in Zhuhai at night, and then fly to Kaohsiung from Zhuhai in the morning on the 29th

It should be impossible, because you have entered Macau twice in this way, and you need to sign twice.

You have a pass, one endorsement for Hong Kong and Macau. You should also have a Taiwan Pass and a Taiwan Entry Permit. <br/>You can go like this. Mainland-Hong Kong-Macao-Zhuhai, using the Hong Kong and Macau Pass and two endorsements, each place can stay up to 7 days. From Zhuhai to Macau, use the Taiwan Pass and stay for up to 7 days. Then fly to Kaohsiung. <br/>Also: Mainland - Hong Kong, then Hong Kong and Macau Ferry Terminal (China Ferry Terminal) by boat to Zhuhai Kyushu Ferry Terminal. Zhuhai Gongbei Port to Macau, use Taiwan Pass and Taiwan Entry Permit, stay up to 7 days. Then fly to Kaohsiung! <br/>If it helps, please click to accept. Thank you 🙏

OK. Your itinerary on the 28th needs to use up the Hong Kong endorsement and the Macau endorsement. On the morning of the 29th, although it seems to be going to Macau, the actual destination is Taiwan. Therefore, this itinerary does not need to use the Hong Kong and Macau Pass and Macau endorsement. What you need is the Taiwan Pass (Chase Permit) and Taiwan endorsement when you clear the customs.

If it's just a one-time sign, it's definitely not possible.

1. From Hong Kong to Macau, use the Macau endorsement;<br/>2. From Macau to Zhuhai, the Macau endorsement is invalid;<br/>3. From Zhuhai to Macau to Kaohsiung, you need to show a valid Taiwan endorsement.
