Do I have to go back to Hong Kong within seven days to fly to Hong Kong with my passport?

Don't worry, your wife won't have a bad record. She transited from Hong Kong to a foreign country with a passport, and there is no requirement that she must return to Hong Kong within seven days. She transits through Hong Kong, and will return to Shenzhen after more than seven days. Even after 1 month, it is legal to transit Hong Kong again, and foreign countries can fly back to Shenzhen directly. In fact, the most important thing to be solved is whether the travel agency allows you and your wife to take off in Thailand. If allowed, because Bangkok's return to Hong Kong is a group ticket and the return date is specified, you may ask your wife to make up the money or buy another ticket. Please understand. ....
