First of all, you must learn to be calm, not impatient or panicked. The more impatient and panicked you are, the more others will think there is something wrong with you.
The second is to learn to remain silent, not to argue or to explain. Some words or things are deliberately manipulated by those who want to smear you, fabricated out of thin air, and the purpose is to lure you into taking the bait. Don’t do it. Argue and explain. The more you argue and explain, the more counterproductive you will be.
Learn to meditate, watch the changes, and let time prove what you have done. How you usually behave is still the same as before, and you don't have to care about other people's opinions.
“When you come out of the mud, you will not be stained; when you wash the clear ripples, you will not be evil.” This popular saying that has been passed down through the ages comes from "The Theory of Love and Lotus". Its author is a famous Neo-Confucian, writer, and philosopher in the Northern Song Dynasty. Zhou Dunyi. This famous quote perfectly explains his honest and upright life. Therefore, as long as a person behaves righteously and uprightly, he can show his noblest, purest and most ordinary side to others.
So, why worry about those rumors?
