In 2022. Is it necessary to cancel the mainland household registration when the mainland moves to Hong Kong with its children after retirement?

The question should be this: first, clarify the concept of Hong Kong identity. Hong Kong identity can be divided into Hong Kong resident identity and Hong Kong permanent resident identity. The difference between resident status and permanent residence is mainly manifested in obvious rights and interests such as political power, whether to join civil servants or not, and of course, some social welfare. Therefore, the so-called Hong Kong identity actually includes two aspects. It is often said that taking permanent residence requires cancellation of the mainland account, and even if you don't want to, the Hong Kong government staff will inform you.

Another Hong Kong identity is usually what we call temporary resident status. This kind of thing does not need to cancel the mainland identity. Just like a visa, you can stay in Hong Kong indefinitely, just renew it. This continuation is indefinite. Some people don't want to renew indefinitely but want to keep their mainland hukou, so they usually have a third-country passport, which can realize the worry-free return of the mainland. Hope to adopt.
