"Don't do to others what you don't want others to do to you" is a Chinese phrase, which means don't impose on others what you don't like. From "The Analects of Confucius - Chapter 12 of Yan Yuan".

Don’t impose things on others that you don’t want to bear. "Do not do to others what you do not want others to do to you" is the earliest principle of Zhou Rites and was highly praised by Confucius, the founder of Confucianism. That is to say, when you ask others to do something, you must first be willing to do it yourself, or if you can do it yourself, then you will feel at ease with your request. The popular understanding is that if you cannot do it yourself, you cannot ask others. Do it.

What this sentence reveals is an important principle in dealing with interpersonal relationships. What Confucius said is that people should treat others based on their own behavior. People should have a broad mind and never be narrow-minded when dealing with others. Instead, they should be magnanimous and tolerant. If you force others to do what you don't want, it will not only damage the relationship with others, but also make things stalemate and get out of hand. This principle should indeed be adhered to in interactions between people. This is a reflection of respecting others and treating others equally. In addition to paying attention to your own existence in life, you must also pay attention to the existence of others. Everyone is equal, and you must not do to others what you do not want to do to others.
