Introduction to Dou Valley: The valley is tens of miles deep and the valley road is relatively open. The mountains on both sides are gentle, bushy, the mountain road is winding, and the river is plentiful. There is Wangdiao Cave on the top of the ridge on the west side of the valley. Myths and legends have made it very magical. In the old days, people often climbed to the ridge from this valley to worship. There is a peak named Chaolai Mountain in the valley, which is tall and majestic. The mountain looks like a minister paying homage to Mount Huashan, hence its name.
