I am a mainlander (17 years old). How to apply for a Hong Kong permanent resident card?

There are only three legal ways to get a Hong Kong identity card: 1, and the immediate family members are in Hong Kong. (including husband-wife relationship, parent-child relationship) 2. Investment immigration. 3. Talents plan to immigrate. Three methods: to obtain a Hong Kong identity card after emigration, you must have lived in Hong Kong for seven years before you can apply for a Hong Kong permanent identity card. Only babies born in Hong Kong can directly have the right of permanent residence, that is, they can directly change their permanent identity cards when they are adults.
