As the saying goes, "A nephew who can't be beaten, a son-in-law who can't be scolded" Why can't you beat a nephew?

This has to start with marriage. Marriage is the marriage of two families with different surnames. Uncle and aunt beat nephew, who is a person with a foreign surname, which easily leads to disharmony between in-laws Therefore, uncles or aunts often take the attitude of "whose children are in charge of who". Just say the nephew's fault, not fight. It is the same for a mother-in-law not to scold her son-in-law. My uncle is my mother-in-law's guest. Mother-in-law often takes a polite approach to children's mutual affection.
