As the ancients said, there is no fish in clear water, and there is no disciple in people's view. This sentence, I understand, is that if the water is too clear, there will be no living environment for fish. People are too harsh to tolerate others, so there will be no apprentices. Therefore, in life, be generous and confused, life will be better and society will be more harmonious.
In a word, being confused is a good medicine, and being stupid is a kind of wisdom.
