The first question to be discussed is whether Lin Daiyu has the right to inherit Lin Ruhai's heritage. If Lin Daiyu is a son, of course there is no need to discuss it; If Lin Daiyu got married before her father died, her parents should have distributed her due property in the form of dowry when she got married. The water spilled by the married daughter becomes someone else's daughter-in-law, economically divorced from her parents, and an independent economic entity together with her husband's family. However, subtly, although Lin Daiyu was fostered in her grandmother's house, she was not married yet. Therefore, according to the property division rules of that era, her father's little wives could not exclude her, and should give her part of the property as her future dowry.
