Zhuangzi further pointed out that heaven and earth coexist with me, and everything is one with me, and clearly put forward the idea of the unity of heaven and man. Generally speaking, people and heaven and earth coexist in the world and are one. We can't put ourselves in a very high position and think that everything in the world should be based on our own will, which will definitely backfire. In a word, Taoism believes that heaven, earth and man are a whole and interdependent, and man should act according to the natural laws of heaven and earth. The current smog phenomenon just confirms its correctness.
