What is the idea of "harmony between man and nature" that the ancients in China often said?

China's ancient geography thought expressed a kind of thought of "the unity of man and nature". Dong Zhongshu in Han Dynasty put forward "man's deputy day", saying: "man has 360 days, even days; The flesh and blood of the body, even the thickness of the land; There are eyes and ears in the world, and the image of the sun and the moon is also; The body is empty, but the pulse is clear, and the image of the valley is also. ..... Day is the end of adults, so section 366, vice day also; Large section 12 points, the number of months also; There are 5 dirty inside, and the number of vice five lines is also; There are 4 limbs outside, and the number of auxiliary seasons (seasons) is also; At first glance, the lieutenant also day and night; At first glance, it is just soft, and it is also winter and summer; At first, I was sad and happy. Deputy yin and yang. " He added: "Heaven and earth are in total, one yin and one yang. Yang is heaven's virtue and Yin is heaven's punishment. ..... Heaven also has emotions, similar to people. By analogy, heaven and man are one. " Therefore, "when everything is in harmony with the name, the name is in harmony with the sky, and the heaven and man are one." "The great source of Tao comes from heaven." As such, "Heaven and earth are the big universe, and human body is the small universe", so the ancient people in China inferred the universe from themselves. In the Book of Changes, the so-called "taking all things close, taking all things far" also contains such a meaning.
