The rivers in the middle and lower reaches of the river are vertical and horizontal, and the autumn crops there are mainly rice. In the average year, the height difference between the river surface and the field surface is between 1-2 meters. This kind of water lifting height is just suitable for the ancient human water lifting method of treadmill. Perhaps, from the time when there was farming in the water town, there was a treadmill, and at least it should have been hundreds of years old.
