Because the woman marries the man's house, the person who has the most contact is the man's mother. The more contact, the more contradictions and frictions. The man rarely contacts the woman's mother, and naturally he rarely has the opportunity to know his mother-in-law, so he rarely says that his mother-in-law is bad.

At present, most marriage modes in China are still that the woman marries into the man's family and lives with him. Instead of leaving family of origin, they formed a new family. Daughter-in-law and mother-in-law have lived under the same roof since childhood. The two generations have different lifestyles, ideas, parenting concepts and so on. They were born without blood relationship, and after a long time, there will be more natural contradictions. My mother-in-law thinks that when you come to my house, you have to abide by the rules of my house, so you have to take care of your daughter-in-law.

Daughter-in-law thinks I am also the little princess at home. Why do I want to come to your house, do laundry, cook and do housework for your family, take care of your parents with the baby, and you have to guide me. Even if some mother-in-law and daughter-in-law do not live together, it is inevitable that mother-in-law and daughter-in-law will intervene in the family of two people.

As for the son-in-law, she visits her mother-in-law's house on New Year's Day. Every time she goes, her mother-in-law treats her as a distinguished guest and makes her happy. Get up early in the morning to do cleaning, prepare a big table of delicious food, and don't forget to prepare a big bag of delicious food for your son-in-law to take home when you leave. At most, it is to say a few words that two people should get along well.

A long-term suffer indignities in her mother-in-law's house, a taste of sweetness in her mother-in-law's house from time to time. Nobody can spit out a few words. Besides, as long as the son-in-law is "kind to his daughter, take time to go home and have a look", he will pass. If he buys a dress and gives some gifts to his husband's family, he will get appropriate points. Mother-in-law has high expectations for her daughter-in-law, and some of them are even harsh. Even if the daughter-in-law washes clothes, cooks, earns money, manages the house, gives birth to children and takes care of them, she barely gets over 60 points.

So this is a test paper with different standards: the "extra points" in the mother-in-law's mind is the "deduction points" in the mother-in-law's mind, and everything the son-in-law does is considered as extra income by the mother-in-law. The mother-in-law takes everything her daughter-in-law does for granted. So some people will say that the mother-in-law is not good, but the mother-in-law is not good.
