I had relatives in Hong Kong in the 1970s and 1980s. Can I move my account?

I had relatives in Hong Kong in the 1970s and 1980s, so I couldn't move my hukou. You can immigrate to Hong Kong in the following three situations:

1, invested 6.5 million in Hong Kong.

2. Excellent talent plan.

3. Marry a Hong Kong person. Therefore, in the 1970s and 1980s, there were relatives in Hong Kong, so the household registration could not be moved. The Hong Kong Special Administrative Region (hereinafter referred to as "Hong Kong"), which is the full name of People's Republic of China (PRC) Special Administrative Region, is located in the south of China and east of the Pearl River Estuary.
