About mainland children moving to Hong Kong?

You must meet any of these conditions.

If you are a minor child, you can apply to settle in Hong Kong, and the entry-exit administration department will approve your application for settlement if there is no problem with DNA identification.

You are an adult, and your parents have no children in Hong Kong. You can apply for settlement at the age of 60. DNA identification doesn't need this. Of course, the Hong Kong Immigration Department will also conduct surveys on Hong Kong parents in Hong Kong to see if they have children in Hong Kong. If it is true, the exit-entry administration department of the mainland public security organ will issue a one-way permit to you within three months.

I wonder how the landlord feels about my answer. Can you add some points?
