Residual agricultural management mode in Neolithic age. It belongs to primitive and barren farming system. First, use a stone axe, then use an iron axe to cut off the dead roots of trees on the ground, and then dry the vegetation and burn it with fire. After burning, the land becomes soft and will not turn over. The surface plant ash is used as fertilizer, but it is not fertilized after sowing. It is usually planted in another place after one year.

Eating hair and drinking blood: refers to the life of eating raw animals with hair and blood before human beings learn to use fire. Li Yun: "No cremation, you eat the real things of plants and animals and drink their blood, just like their hair."
