Swearing is a traditional culture in China.

Swearing is not as good as parents, and the next sentence is to expose people without revealing shortcomings. Don't hit your face, don't swear, and don't expose people's scars. These three sentences have always been the bottom line of people. When you are angry and impulsive, you can hit anywhere, but you can't hit others in the face. Swearing also exists under special circumstances, that is, you can't say it every day, let alone insult your parents. Teasing a person, you can't catch a person's shortcomings and mention them many times.
