The old sayings that warn against slandering people behind their backs include:

1. Those who talk about right and wrong are right and wrong.

Those who talk about right and wrong are right and wrong. The proverb means that people who talk about right and wrong are right and wrong. Since they say bad things about others in front of you, they will naturally say bad things about you in front of others. Their willingness to talk about people's rights and wrongs is the reason for their excessive jealousy. In their hearts, they often want others to become more and more unlucky and embarrassed. Wise people will not tell their true feelings when talking to such people.

2. Sit quietly and think about your own mistakes, and don’t talk about others’ faults in small talk.

Sit quietly and think about your own faults; don’t talk about others’ faults in small talk, proverb. It means that a person should always think about his own faults when sitting in meditation, and should not talk about the rights and wrongs of others when chatting with others.

3. No one talks behind anyone’s back, and no one talks behind anyone’s back.

"Zengguang Xianwen" says: "No one talks about someone behind their back, and no one talks about someone behind their back." It means being talked about behind someone's back and talking about others in front of others are common things in life.

4. There is no better way to save the cold than to wear a heavy coat, and to stop slander, there is no better way than self-cultivation.

To save the cold, there is no better way to save the cold than to wear heavy fur, and to stop slander, there is no better way than self-cultivation.
