Language comes from Laozi. The whole sentence is: "I don't see myself, so I know;" Self-evident, so obvious; Do not cut yourself, have merit; Not complacent; So long; The husband does not dispute, and the world cannot compete with it. " It means: don't show yourself, don't be self-righteous, it will be more brilliant; Do not praise yourself, so you have achievements; Don't think you are talented, so you are respected; Only those who don't argue with others, no one in the world can argue with him.

This passage fully embodies Laozi's philosophical thought of "weakness conquers strength". Laozi's so-called "indisputable" is not to give up everything, but to be invincible by striving. The ideological system of "being confused is hard to change" and "losing is a blessing" spread in later generations has something to do with Lao Tzu's so-called "indisputable virtue"
