I think everyone will get angry when their mother-in-law scolds their children, especially when some mothers-in-law swear, especially when these words are vicious. It's hard for very young children to accept these words. Perhaps for the older generation, they still believe in filial piety under the stick in educating their children. This sentence has little effect in modern society. It may be more useful when raising a child, but this child is still useful.
If the mother-in-law says the child is right, it is understandable that the child did something wrong. After all, it's easy to say anything when a person is angry. If so, we can still accept it. If the mother-in-law often scolds her children and doesn't avoid herself, we can't accept it. We can communicate and mediate with our mother-in-law If she doesn't correct it, we must.
If we have the conditions to take care of our own children, we must take care of our own children. After all, there is a big age gap between our mother-in-law and us, and there is also a problem in educating our children. It is best to bring their own children.
