In the light rain, came to Shuhe Ancient Town, in addition to the lively bar tea rooms on both sides, there are some traditional and ancient cultures preserved. At first, I thought that the three-eye well was a well with three springs, but it was not, and the wisdom of the local people was crystallized. The canals are sequentially three square wells, and the water flow speed is reduced by staggering positions, and then the three square wells are specified for different uses according to the flow of water. The first mouth is used for drinking, the second is used to wash vegetables with rice, and the last is used to wash clothes, which ensures the safety of drinking water in the town and saves water resources. Praise the wisdom of the working people.
