As for the question of "can husband and wife live together when they return to their mother's home", the customs are different from place to place, so the practices are different. In some places, a wife can't live with her husband at her mother's home, but in some places, a wife can live with her husband when she comes back to her mother's home.
So, in some places, why don't wives be allowed to live with their husbands when they are at their mother's home? This is actually related to some feudal superstitions. Some people think that their daughter is an outsider when she is married. Outsiders have a husband and wife's life in their own home, which will bring disadvantages to their own home, so the two can't be allowed to live together in their mother's home. In fact, this is a way of discriminating against women, and it is also the expression of the idea that men are superior to women in family relations.
Of course, there is no scientific basis for the view that an outsider's husband and wife's life in his own family will be harmful to his own family, so it is increasingly ignored. What's more, if his daughter is married or his own daughter, since his son-in-law has married his own daughter, he can't be said to be an outsider. More and more people realize that it is beneficial to promote their husband and wife relationship to let the two live together in their mother's home. As parents, they should allow the two to live together and actively create conditions for them to live together.
For example, our wife can't live with her husband in her mother's house, but now the situation is that each family has a special room for her daughter and son-in-law. It should be said that this is a manifestation of social progress and the result of the implementation of the concept of equality between men and women in family relations.
Of course, if you live in a place where your wife is not allowed to live with her husband at her mother's house, and your wife does not hold any objection, I think that although this approach is extremely unreasonable, in order to maintain the harmony of family relations, the best thing is to do as the Romans do, after all, the good days are still long. If the two emotions last for a long time, why should they go from day to night and endure it. What do you think, friend?
