Those who know are wise, those who know themselves are clear, those who win are strong, those who win are strong, those who are satisfied are rich, and those who wish to lose their position will not die for a long time. Laozi: The Classic of Tao Te Ching: Chapter 33: People who know others are wise, and those who know themselves are wise. The winner is strong, and the winner is strong. The contented are rich. Those who are strong have aspirations. Don't lose its position for a long time. People who die but don't die are still alive. People who know others are smart. Note: It is common sense for mortals to know only the right and wrong of others and not their own. . . . . . . . . . . . . . . . . . He who knows himself knows. Note: Only those who know the shortcomings of their actions are truly wise. The winner is strong. Note: People who can surpass others are smart. He who conquers himself is a strong man. Note: Those who can overcome their privacy are truly self-reliant. The contented are rich. Note: Only those who can understand the truth and are satisfied with not being greedy can be considered rich. Those who are strong have aspirations. Note: Those who can push themselves onto the road are truly ambitious. Don't lose its position for a long time. Note: People who have not lost that place (the place where they really stopped) can persist for a long time. Those who die but not die are still alive. Note: A person's prosthesis is gone, but his reputation will remain in the world forever, his spirit will return to the root, and he will die after living out of life. This is called longevity. Knowing others is wisdom, and knowing yourself is wisdom. It is powerful to defeat others, and it is also powerful to defeat yourself. A contented person is rich. People who persist in doing things are ambitious. Having without losing is lasting, and dying without being forgotten is long-lived.
