Husband and brother get married and become sisters-in-law. Can't they go back?

As a sister-in-law, you must attend the banquet at your husband's brother's house. As the old saying goes, eldest brother is father and eldest sister-in-law is mother. As a sister-in-law, it is natural to hold a venue for my brother to show that this is a harmonious family and let others admire you.

If you don't attend, it will make people feel that your husband's younger brother doesn't even have a good relationship with his family, and it will definitely be more difficult to get along with others.
