Sister-in-law is cooking at her parents' house.

For the eldest sister who is in charge, you should stand up and have a good talk with her. Ask the elder sister-in-law if she is a brother at home, and her brother and daughter-in-law can't live any longer. Otherwise, we won't live a good life. If you say so, we will live. How much help can you give us in life? We still have to live by ourselves day by day. So, tell my sister, as long as you take care of your home, don't go home and make irresponsible remarks.
