As for your Hong Kong and Macao Pass, I will give you a standard:
Name: Hong Kong and Macao Pass
Conditions: Persons with Guangzhou household registration.
Procedures: To apply for the 2000 version of Hong Kong and Macao Pass for the first time, the personnel of provincial units can choose to apply to the third-level exit-entry administration department of the province, city or unit and the region (county) where the household registration is located, and the personnel of municipal units can choose to apply to the second-level exit-entry administration department of the city or unit and the region (county) where the household registration is located; Other personnel apply to the district (county) public security exit-entry administration department where the account is located or where the unit is located. (Non-registered personnel are required to apply at the place where the unit is located, but do not need to submit the opinions of the unit, and cannot provide work permits or other certificates. In principle, they should apply at the place where the account is located. )
With a valid 2000 version of the Pass to and from Hong Kong and Macao, regardless of whether it was endorsed before, the applicant can apply to the acceptance department in person or entrust a travel company with the right to operate outbound tourism to apply on his behalf.
Simply put, if you are not registered in Guangzhou, you can only go back to the Exit-Entry Administration Office of the Public Security Bureau where your household registration is located. So, whether to move or not, here you can weigh the pros and cons and see which is more convenient.
I hope the answer will help you.
