In fact, compared to obtaining permanent residency overseas, Hong Kong's policy is very flexible; as long as the renewal is handled in an orderly manner, obtaining permanent residency is very easy.

Hong Kong does not have an immigration monitoring requirement, nor is there a clear requirement for the number of days spent in Hong Kong; long-term residence is not required for renewal.
 

The policy of the Immigration Department is to maintain regular contact with Hong Kong, so during these 7 years, you can renew through business and living renewals.
 

► Business renewal means that your work in the mainland has business dealings with Hong Kong, and the Immigration Department determines that you contribute to Hong Kong; in this case, you do not need to frequently visit Hong Kong.
 

► Living renewal requires having entry and exit records for Hong Kong. If you visit frequently, such as friends from Shenzhen going 5 or 6 times a year, long-term residence is not necessary. However, if friends from Beijing or Shanghai go only once or twice a year, then each visit requires a longer stay to maintain living records for renewal (utility bills, transportation proof, etc.).
 

The Hong Kong Immigration Department will consider various aspects of the applicant, including work and family (such as children's education).
 

As long as you can convince the Immigration Department through your application materials that you genuinely want to develop and live in Hong Kong, renewing your visa will not be a difficult task.
