My parents-in-law look down on my parents. What should I do?

Then there should be less contact between them You should do what you should to be filial to them, no matter what they say about you, because no one can replace your parents who raised you. Don't marry a chicken with that old idea. If they treat you as their daughter, they won't look down on your family. You should ask your husband to be more concerned and filial to your parents. This is the right thing. It's your mother's family that will help you in the future, not you.
