Everything goes with the flow and is not forced. Some people, some things, should be treated indifferently and cannot be forced. Cultivation is the cultivation of a person's quality. Really can't say only understand. Personally, I feel that self-cultivation is a requirement for my words and deeds, so that I can do everything in communication with others. There is also the cultivation of personal qualities. For example, indifference, sincerity, and principles in doing things. . . Personally, I like it better: a word from a gentleman is a promise. Perhaps it is a summary of self-cultivation. I hope my personal opinion will help.
