It means: if you want to succeed, you must first make others succeed. If you want to be understood, you must first understand others. This is an important thought of Confucius and an important principle of "benevolence". This is an important criterion for dealing with interpersonal relationships in Confucian moral cultivation, that is, "loyalty and forgiveness", which requires inferring the thoughts and feelings of others according to one's own inner experience, so as to achieve the purpose of "pushing oneself and others". It and "don't do to others what you don't want others to do to you" introduce the principle of treating people from two aspects, namely, don't do to others what you don't want others to do to you, from desire and from self. The two complement each other and constitute a complete Confucian moral principle.
