Traditional farm tools and plows

Before the Spring and Autumn Period and the Warring States Period, the tools were mainly class tools and chisel tools. After the Spring and Autumn Period and the Warring States Period, iron and Niu Geng were used, and Qu Yuan Plough was invented and used in the Tang Dynasty.

Iron is hard, sharp and light, far better than heavy and rough wood and stone tools and precious bronze tools, which makes deep ploughing possible and greatly improves productivity. The arrival of the Iron Age marked the remarkable improvement of social productive forces in China. Niu Geng liberated human resources, which was a revolution of China's agricultural forces and greatly improved the farming efficiency; Qu Yuan's plough has the characteristics of reasonable structure, convenient use, flexible rotation and adjustable depth, which is very suitable for paddy field cultivation. Its appearance indicates that the traditional step plough in China has been basically finalized, which is a breakthrough in the reform of farm tools after the development of ploughing in Han Dynasty.
