Whether to let my parents-in-law live with me

This can't be together, and there will be more troubles after being together. It's not that I can't stop. It is also right to stay and see my daughter once in a while. But permanent residence is not enough, although the son-in-law is half a son. Discuss with your wife and build a house in your hometown. Let your wife discuss it with her sister, and then the money. After all, everyone has a family.
