The post-2000 generation is so wild. A couple of days ago, two post-2000 young lovers told me they found a legal loophole, saying that not getting married or registering a marriage is really awesome. They analyzed it for a while, almost confusing me. They said there are five benefits of not registering a marriage that can even save lives: First, not registering a marriage still allows you to have children, and the children can directly take the mother's surname, and both parents' household registrations can be maintained.
