Has anyone traveled this route from Shanghai to Hong Kong and Macao, then from Hong Kong to Xiamen and finally back to Shanghai?

① There is nothing wrong with the self-help tour route you designed. Before you travel, just apply for a Hong Kong travel endorsement and a Macau travel endorsement.

② You have a Hong Kong endorsement, and you can stay in Hong Kong for 7 days. This 7-day stay is counted from the day after you enter Hong Kong, which means you can stay in Hong Kong for 8 days before and after. The simple notation is: you arrive in Hong Kong on Monday and can leave Hong Kong at the latest next Monday; You arrive in Hong Kong on Tuesday, and you can leave Hong Kong next Tuesday at the latest. And so on.

③ During your stay in Hong Kong, if you travel to Macau and then return to the Mainland via Hong Kong, the Hong Kong Immigration Department counts your stay in Macau as an "incidental trip", which means that you don't need a second endorsement if you count your stay in Hong Kong with one endorsement. However, there are special regulations as follows:

④ If the day you return to Hong Kong from Macau is the eighth day after you enter Hong Kong, you should have left Hong Kong on the same day according to the stipulation of one-time endorsement of stay in Hong Kong. However, in order to facilitate tourists to return to the mainland via Hong Kong, the Hong Kong Immigration Department has given them an extra day to stay in Hong Kong, allowing them to leave Hong Kong before midnight the next day.

⑤ If the day you return to Hong Kong from Macau is the seventh day after you enter Hong Kong, you must leave Hong Kong before midnight the next day according to the stipulation of one-time endorsement for staying in Hong Kong.

⑥ If the day you return to Hong Kong from Macau is more than the eighth day after you enter Hong Kong, you can't return to the mainland via Hong Kong without another Hong Kong tourist endorsement. You can only return to Zhuhai from Macau or fly from Macau to Xiamen.

⑦ You can stay in Macau for seven days once you sign an endorsement for Macau, but if you want to return to the mainland via Hong Kong after visiting Macau, you must follow points 4 and 5.
