Non-permanent residents of Hong Kong who remarry in the Mainland will not have their registered permanent residence smuggled back to the Mainland. Marriage does not involve household registration transfer. Non-Hong Kong permanent residents have permanent rights in Hong Kong as long as they hold a Hong Kong visa for seven years. Those who haven't seen each other for seven years will remarry during this period, and the other party's household registration is in the mainland, which does not involve household registration transfer.
