Primitive agriculture has developed from slash-and-burn to what kind of digging tools are used for various purposes.

There were three modes of agricultural production in ancient China: slash-and-burn cultivation, stone hoe cultivation and iron plow Niu Geng. 1 was slash-and-burn in primitive society. The land belongs to the clan commune, and the tools and appliances are very simple. People work in clans, cultivate collectively, enjoy the fruits of labor, work together and consume together, without oppression and exploitation. 2. It was a stone hoe in Xia, Shang and Zhou Dynasties. The land belongs to the king (well field system), and the tools have been improved, mainly including thunder, stone knives and stone hoes. Laborers are slaves and civilians. They collectively cultivate mineral fields, and slave owners deprive them of the fruits of their labor. Niu Geng has been an iron plow since the Spring and Autumn Period and the Warring States Period. The land is privately owned, and the production tools are iron farm tools and Niu Geng. Workers are farmers. They either cultivate their own land or rent the land of the landlords. Taking the family as a unit, men plow and women weave, self-sufficient, and pay attention to intensive cultivation. Exploited by feudal countries and landlords.
