(3) The helpless elderly and children in the Mainland have to rely on their immediate family members and close relatives in Hong Kong and Macao; (4) The property of immediate family members who have settled in Hong Kong or Macao has not been inherited, and only mainland children who have settled can inherit it; (5) There are other special circumstances that must be solved.
