Introduction to waterwheel spinning: In the distant ancient times, the industrious Tujia ancestors worked hard to cultivate the fields and had to rush for watering. In order to avoid severe drought years, the fields would crack and the crops would wither. The Tujia people were in long-term production. Various waterwheels were created during labor, and later a round plate was created that could rotate on its own without manpower and rely on the impact of water, and then be fed into farmland. These waterwheels were used for grinding flour, pounding rice, making paper, pumping water for irrigation, etc., which fully demonstrated the ingenuity of the Tujia ancestors.
