If your father-in-law and mother-in-law always dislike your daughter-in-law and find fault with her, how should you deal with it as a son?

Filial piety comes first among all good deeds. You are juniors, and filial piety is a traditional virtue. If mother-in-law and daughter-in-law don't get along, don't make things difficult for your husband, they are his parents. What a husband should do is to discuss the source of their dissatisfaction with their daughter-in-law in front of their parents, and in the spirit of filial piety to the elderly, secretly discuss with their daughter-in-law how to deal with the old man's temper, so that they can have nothing wrong with them. If the daughter-in-law can do this, it means that she is very cultivated and understands that respecting and loving the elderly is the duty of a human being. If your daughter-in-law goes against your parents-in-law and talks about everyone being equal, then you are totally wrong. In the end, you will not be able to take advantage, but will let others poke your spine. In this way, your road will become narrower and narrower in the future, so it is not a wise move to go against the old man.
