What should I say when my uncle hits my aunt's nephew?

In fact, adults beat and scold each other, most afraid that the younger generation will come out to recuperate and feel that they have no face. If the younger generation is sensible and can move with emotion, they can get better results. When an uncle hits his aunt, his nephew should first take her side and criticize her uncle. Then, he should calmly find out the cause and effect of the matter and make a judgment on the merits. Finally, he will urge the unreasonable party to apologize politely and tell them to live in harmony.
