The second point: the problem of life. Parents are old, do they live with their sons or daughters? A n experienced person tells the truth. If she is with her daughter, her mind is more delicate and she can carefully consider every detail of her parents' life, so she can provide her parents with a better life and make them comfortable, and most of her sons-in-law are very filial to their parents. But there are often contradictions between mother-in-law and daughter-in-law. Even if the relationship is very good, sometimes the daughter-in-law will have some other small thoughts, so the parents may not be so happy.
The third point: economic problems. In most families in China, men earn more money, so many parents don't have to worry about financial problems when they live in their sons' homes. Many sons will take the initiative to give their parents pocket money so that their parents are not short of money. If you live in a son-in-law's house, the gap may be too big, because the burden of supporting the family originally falls on the son-in-law. Meanwhile, my father-in-law and mother-in-law live in. Although the son-in-law won't say anything, many old people will feel embarrassed and will take the initiative to help the family do more things to make up for it by taking on housework.
However, gender equality is now advocated. Both sons and daughters have the obligation to support the elderly. It is entirely up to the elderly to choose. It is normal to live in a son's house or a daughter's house. As long as the elderly are willing, no one can object.
