Why can't children live in the woman's house?

The phenomenon that children can't live in a woman's house is a custom change left over from the old society. In the old society, there was such pressure. At the beginning of that year, the first daughter could not spend the New Year in her family. These are the customs of the old society, but now it is a new society. How can a son-in-law not spend the night at her parents' house?

Uncle: Generally speaking, it refers to the son-in-law. Uncle or son-in-law according to the status of children.

Noun explanation:

Uncle is a common name, and the word uncle is derived from girls. In the past, girls in large families were called girls when they were a little older. The Lord gives birth to a big generation, so he is called Niang. After marriage, his son-in-law is the same generation as a girl, so the inferior people generally call him son-in-law. Of course, if everyone calls him son-in-law, it's really outrageous. As for why Lian Yue's parents later called her son-in-law son-in-law, it is unclear.
