Why should I be separated from my parents when I grow up and get married?

Married people are their own independent new families. The basic composition of the family is that husband and wife and children will go out and form their own family independently when they grow up. After marriage, it means that they are no longer members of their previous family, but members of a new family. As can be seen from the changes in household registration, the adjustment of the head of household is not simple due to different living conditions. This adjustment also means the formation and rebirth of a new family. The emergence of responsibility in China is due to the theory of filial piety and the traditional concept of family reunion in China, which holds that the family is composed of husband and wife and their branches, and a series of contradictory concepts have emerged.

I think the current practice is to analyze the specific situation. If all your family members think that they should be separated, this is of course reasonable. If you don't want to be separated, it is not unreasonable to handle many contradictions reasonably.
