Why can some cities handle individual tours of Hong Kong and Macao Pass, while others cannot go with tour groups?

Whether to open individual tours is decided by the relevant departments of Hong Kong and the Mainland through consultation. It doesn't mean that if everyone wants to go, others have to accept them as gifts, but also depends on their affordability. If they are unable to accept such a large tourism market, the service quality will be uneven, which is not good for anyone.

If you want to travel to Shenzhen, Hong Kong, Macao, Hong Kong and Shenzhen, it is best to sign in Hong Kong twice, and Macao once is more secure. Just buy a visa to go to Hong Kong before going through customs. Don't cheat the travel agency into buying more than three times. Signing the bill is only the proof document that China Customs will collect before the group tourists leave the customs, and they only need to buy it once.
