"Don't do to others what you don't want them to do to you." This sentence comes from the Analects of Confucius, which means that if we don't want what others do to us, we shouldn't do what others don't want us to do. Confucius believed that people should have a moral conscience, and should not impose what they don't like on others, nor should they impose what they don't like on others, but should be polite to show respect.
This sentence embodies one of the basic principles of Confucius in dealing with others and is also an important concept of Confucian ethics. It conveys Confucius' idea of mutual respect and equal treatment among people, and emphasizes the moral principles that individuals should follow in their behavior. This sentence has also been widely quoted and passed down, and has become one of the classic sayings in Chinese culture, which has had a far-reaching impact on later generations.
