Introduction to the Waterwheel Kingdom: At the source of the rafting, there are 102 waterwheels for irrigation, mills, rice harvesting, and a rather spectacular and interesting group of waterwheels, which are reminiscent of the sunrise, An ancient farming scene at sunset, with men plowing and women weaving. Walking all the way into the mountains, the fairy tale-like waterwheel kingdom is fascinating. It can be called "the largest and most interesting waterwheel group in China".
