Talk about being a door-to-door son-in-law Is it unfilial to parents?

Door-to-door son-in-law is what we call an inveterate woman, also known as adoption. A son-in-law refers to a daughter's husband. Under normal circumstances, a daughter is going to marry a son-in-law. The door-to-door son-in-law means that the woman is responsible for the cost of marriage. After marriage, the man lives in the woman's house, lives with the woman's house, and later dies for the woman's house. In the past, it was usually people who had no money to marry a daughter-in-law at home who would be the door-to-door son-in-law for others. It will be a shame for you to be looked down upon by others as a door-to-door son-in-law. Moreover, in the past, the custom of the son-in-law was to support the woman's parents and not her own. Therefore, some people will think that not being a son-in-law after being killed is unfilial to their parents. Moreover, the door-to-door son-in-law is afraid of being looked down upon in the woman's house and is a head lower than others. Forget it, that's all in the past, and now there's not so much to say about being a door-to-door son-in-law Now most of them are only children, and some families don't want to let their precious daughters marry far away, so they will choose to let their daughters find a family with two brothers and recruit a door-to-door son-in-law. Now a family has only one precious daughter, and the son-in-law is treated as half a son. How can there be such a saying as inferiority complex? No parents can't support themselves. Parents are old, two brothers can take care of themselves, and two families take turns to support them. Besides, filial piety is not filial, isn't it because you can be a son-in-law just because you're not a son-in-law? Filial piety lies in behavior, not in title.
