Introduction to Dazhai Valley: This ditch runs northeast to southwest, starts from the west side of Taipingding in the northeast, and finally flows into Huangshiya Reservoir, with a total length of 3.5 kilometers. There are cliffs and strange rocks on both sides of the ditch, giving it a primitive forest look. Therefore, the ditch extends in front of Dazhai Mountain, hence the name Dazhai Valley.
