Confucius has a famous saying: the knower is happy [sound: Yao, meaning: hobby] water, and the benevolent is Leshan; The knower moves, and the benevolent is quiet; People who know are happy, and people who are kind live long.
It is vivid and profound to describe mountains and rivers as different people have different opinions. This is like Zhu's comment in The Analects of Confucius: "Without a deep understanding of benevolence and wisdom, such a description can never be made." The sage has both wisdom and benevolence, so the patent right of this description belongs to him.
A wise man is a wise man. Smart people are rational, quick-thinking, active and active, just like water is always flowing, so compare it with water.
A benevolent person is also a kind person. Good-hearted people are content with justice, kind and tolerant, but not impulsive, quiet and stable, so use mountains as a comparison.
