Mencius thought: "A gentleman has three pleasures, but the king of the world does not exist." . Parents exist, brothers have no chance, and they are happy. Be worthy of the sky, live up to people, and be happy. If you are educated by talented people in the world, you will have three pleasures. "

Analysis: in the trilogy, parents, brothers and families live in harmony, which should be said to be family happiness; Being a man and doing things with a clear conscience should be regarded as your own pleasure. The above two kinds of happiness can be achieved by many people, and they are also the foundation of settling down and living, and are the happiness of families and individuals. Sanle is different. Not everyone can "be educated by the world's talents." Therefore, Sanle is bliss, which cannot be compared with family and one's own happiness.
