Do non-child parents have the opportunity to settle in Hong Kong?

The applicant is a permanent resident, over 60 years old, unattended, and needs to rely on immediate family members or close relatives who have settled in Hong Kong or Macao.

That is to say, parents are over 60 years old and have no other children outside Hong Kong. If you have two or three children in Hong Kong, this condition is also suitable. But if you have a child registered in the mainland, it won't work.
