Harmony is the most important, the doctrine of the mean is conservative. China culture emphasizes harmony and unity, which is in sharp contrast with western culture. This huge difference between Chinese and western cultures largely reflects the different characteristics of farming civilization and commercial civilization. China's traditional culture is rooted in farming civilization, showing a "static" feature, attaching importance to the harmony between nature, man and nature, man and society, man and man, and man's own body and mind. Advocating the harmonious spirit of harmony is the most typical embodiment of China traditional culture in the ideological tradition of "harmony between man and nature". In the eyes of ancient thinkers in China, heaven, heaven and human nature are similar and interlinked, thus achieving harmony and unity. On the relationship between man and nature, China culture pays more attention to the harmonious unity of man and nature, while western culture emphasizes that man should conquer and transform nature. This point can be clearly confirmed from Confucius' so-called "courtesy and harmony are precious" to Mencius' "weather is not as good as geography, and geography is not as good as human harmony" In ancient China, the doctrine of the mean can be said to be a way to adjust social contradictions.
