Introduction to Waterwheel Fengqing Street: Waterwheel Fengqing Street includes the Emerald River, Fengqing Street and the largest waterwheel group in Asia. There are up to 6 waterwheels in the group, with a maximum of 28 meters, a diameter of about 20 meters, and a minimum of 24 meters. The weight of a single waterwheel is 9.6 tons, the largest in Asia. The shape of the Cha'a waterwheel resembles a huge ancient wheel, which can lift water up to 26 meters high. The center of the wheel spokes is a thick axle. There are about 50 wooden buckets diagonally installed around the wheel, and there are twice as many horizontal boards as the wooden buckets. . The rapids hit the horizontal plates on the round wheel, and the wheel slowly rotated. At this time, the wooden bucket submerged in the water is filled with water. When it rises to the top of the round wheel, you can see the waves rising up and splashing towards people like flying beads, as if taking tourists to the ancient farming era.
