How did agricultural farming methods evolve in ancient China? What was its performance?

The main farming method of primitive agriculture is slash-and-burn. People first used stone knives and axes to cut trees, dry them in the sun and then set them on fire, and then used stone plows to turn the soil and plant seeds.

Bronze agricultural tools appeared in the Shang and Zhou Dynasties.

During the Spring and Autumn and Warring States Periods, people began to use iron farming tools and ox plowing and gradually spread them. After the Han Dynasty, iron plow and oxen plowing became the main farming method of traditional agriculture in China.

Sui-Tang period, the Jiangdong region appeared in the curved plow. By this time, China's plow plowing has been quite perfect.
