China's feudal economy has been further developed, especially in the north. The leap of productive forces triggered the revolution of production relations. During the Spring and Autumn Period and the Warring States Period, the well field system was gradually replaced by feudal private ownership of land, and was finally established through reforms in various countries.
At the beginning of the Spring and Autumn Period, local governors competed for supremacy, but the original situation of Zhou Wenhua's supremacy was gradually destroyed, and local cultures began to show a trend of "localization".
After the Warring States period, this situation became more obvious. In terms of word usage, it can be roughly divided into five major departments: Eastern Qi, Northeast Yan, Southern Chu, Northern Jin and Western Qin. The characters of each system are generally similar, with only a few differences, so there is not much problem in the exchange of documents.

The leap of productive forces triggered the revolution of production relations.

A major development is the adoption of various measurement methods, such as recording population and taxes, and counting crop yields.
