The core cultural thought of the unique life concept of the Chinese nation is a word "harmony", which has evolved into a spirit and sublimated into a realm after more than 5,000 years of heart-to-heart communication.
Source: At the beginning of Sun Tzu's Art of War, there is a cloud "Heaven and Earth are in harmony": "Soldiers are the major events of the country, the place of life and death, the way of survival, one saying, two saying, three saying, four saying, and five saying. Those who know this will be ignorant, those who know this will win, and those who don't know this will be invincible.
Vernacular interpretation: the person who uses soldiers is the most important thing of a country, which is related to the life and death of the military and civilians and the survival of the country. One is Tao, the other is heaven, the third is earth, the fourth is general, and the fifth is law. These are all things that the general can't ignore. If you know, you can win, but if you don't know, you can't live.

The unity of heaven and man is the main idea of Taoism. Is the essence of Zhuangzi thought. It is the inheritance of Laozi's thought. It has a profound influence on China culture. Taoist culture in China is deeply influenced by it.
Zhuangzi's "Tao" is heaven, imitating nature's "Tao", not man-made harm. In Zhuangzi's philosophy, "heaven" is two opposite concepts to "man". "Heaven" represents nature, and "man" refers to everything that is artificial and deviates from nature. The word "artificial" is a "fake" word when combined.
Zhuangzi advocated obeying the Heaven and discarding the "artificial" and "false" impurities in human nature. It is the "virtue" advocated by Zhuangzi that obeys the "heaven" and thus communicates with heaven and earth.
