I have a Hong Kong and Macao pass, but I am visiting relatives. Can I go with the tour group?

Judging from your question, you are still dizzy about leaving the country. First of all, if you have a Hong Kong and Macao pass to visit relatives, then you are free to travel to Hong Kong and Macao. As for whether to travel during your stay in Hong Kong and Macao, it is entirely your personal business, and has nothing to do with entry and exit management. If you are going to sign up for a tour in China, you can take care of yourself when you go to Hong Kong and Macao, and sign up for a tour in the local area to avoid unnecessary trouble.
