Don't do to others what you don't want others to do to you, which is the way to treat others advocated by Confucianism.

Personally, I think it's like this: don't impose on others what you don't want to do or what you don't want, or treat others with the same attitude. For example, when we go out to do business, we often meet the so-called ugly faces of the staff, but when others come to their own units or posts to do business, we must serve them with a peaceful attitude and enthusiasm. Instead of adding to others' troubles.
