By the way, travel from Hongkong or Macau to Taiwan Province Province. How to go through the relevant procedures (see the instructions for details)?

First of all, divide your trip into two parts, one is to Taiwan Province Province, and the other is to Hongkong, which makes it easier to break it down.

First of all, to go to Taiwan Province Province, you need to bring two kinds of certificates. One is the passport for mainland residents to travel to and from Taiwan, which you also mentioned in your explanation. Here, you need to know what your passport endorsement is, and then whether the endorsement is still valid before you leave the country. You mentioned that you started from Beijing, which is a city that can apply for free travel endorsement in Taiwan Province Province. Free travel endorsement will be marked with "G" endorsement type. Then, if you didn't get a pass in Beijing, you may have got a tourist visa for Taiwan Province Province, "L". Simply understand, the "G" sign is free to travel, while the "L" sign is only allowed to join the group.

The other is the entry permit issued by the immigration department of Taiwan Province Province. If the mainland pass is free, the entry permit can be directly entrusted to a qualified travel agency. If you apply for a tourist visa, you can only join a tour group, and a group travel agency is responsible for handling it for you.

In terms of free travel, only when you have a free travel pass to Taiwan and a free travel pass to Taiwan can you go to Taiwan Province Province smoothly. According to what you said above, in fact, you can fly from Beijing to Hongkong with your Taiwan Pass and Taiwan Province Entry Pass. After staying in Hong Kong for a few days, you can also check in at the Hong Kong airport with your Taiwan Pass and Taiwan Province Entry Pass. If you don't know how to use it, you can use the Hong Kong and Macao Pass to go to Hong Kong, and then use the Taiwan Pass and Taiwan Entry Pass to go to Taiwan Province Province.
