Heaven taboo, human taboo. It means that everything should have a margin, so that creation can't avoid me and ghosts and gods can't harm me.
Idiom: Heaven avoids profit, industry is not profitable, water is overflowing, and monthly profit is losing. External worries: external attacks, jealousy, foreign invasion.
No matter what you do, you should leave room. Don't do things too badly, so that even the creator's God won't envy me and ghosts won't hurt me.
If everything is required to be perfect, all contributions are expected to reach the peak. Even if there is no civil strife, it will inevitably lead to foreign criticism and jealousy.
Things are like floating clouds, circulating and changing rapidly. "Zhouyi Fu Gua Xiang Ci" said: "Fu, it sees the heart of heaven and earth"; "The sun is round and the moon is round."
Confucianism got spiritual enlightenment from repeated natural changes: "No malice, no, never to return." That is to say, life is ever-changing, just like water, when things flourish, they will decline, and when things decline, they will reverse.
In this kind of life, we should pay attention to proper discretion everywhere when dealing with people. Too much is not enough, too much is a big mistake, too much is a great evil, and just right is impartial neutralization.
As the saying goes, "Don't be a man, don't talk all the time." Lian Po was really incompetent and had to go to Lin Xiangru to make amends. Zheng Bo talked too much, so he had no choice but to dig for spring and went to see his mother. You can leave room for everything and avoid going to extremes.
