Daughter-in-law is often angry with my father-in-law and says she can't stand it. To put it bluntly, it's all small things. What should I do?

After all, they are related by blood, and nothing can be avenged overnight. However, as the husband of your daughter-in-law, you still have to fight back, do a good job in the hearts of both sides, and strive to improve this state. After all, old people will be more talkative when they are older. As children, we should be more considerate and understanding. After all, the elderly are just around us, and sometimes nagging is also a sign of love, but most people can't accept it. If one day the old man is gone, as a child, my opinion is that you can not do what the old man says, but you must listen. One is respect, and the other is filial piety.
