What do you mean by introspecting your body, thinking about yourself all the time and being good at repairing your body?

Self-examination, continuous thinking and self-improvement means to analyze yourself more, find reasons from yourself, learn lessons by summing up your own shortcomings, and then sublimate yourself.

This sentence comes from the Analects of Confucius, "I will keep my body for three days" and is often used to encourage myself. Lao Tzu also said, "No one is to blame for the trip to the Avenue". No one is perfect, but we should reflect on ourselves. It is a good accomplishment and great wisdom not to blame others easily and to look at yourself more.

Connotation:

Idioms tell people that introspection is what a gentleman does and a necessary accomplishment for a gentleman. "Visiting the body three times a day" and "seeing the sage Si Qi, not seeing the sage but looking inward" are all introspection ways left by Confucian saints. Introspection is a spontaneous behavior, which depends on the individual's own consciousness and understanding.
