What economic theories did China have in ancient times?

China economics is a highly original new economic paradigm founded by China people according to the symmetrical logical thinking mode contained in China traditional culture. It is essentially different from the existing western schools of economics in theoretical basis, system structure and practical function. It not only reflects the general economic laws of mankind, but also reflects the special economic laws of China. It can effectively explain China's economic phenomenon, guide China's economic development, and become the theoretical basis for China to establish a perfect market economic system. In the era of globalization, China's economics should be the logical development of western economics and the compatibility and transcendence of the latter; China economics has replaced western economics as the mainstream of human economics, which is a natural historical process of the development of human economic thought, and shows the arrow of time alternately through space. China economics is the representative and typical form of oriental economics. China economics is a paradigm concept, not just a regional concept. Symmetry, nonlinearity and complex system theory are the basic characteristics of China's economic paradigm. China's economic paradigm is symmetrical.
