Introduction to Canglang Valley: Entering the mountain from the Xiyuan Gate of Culai Mountain, Tuanshang Valley, Chunyangpo Valley, and Dongshan Valley merge into a stream. It flows in front of the temple and turns westward. Because the ditch is narrow and there are many huge rocks, the water surges on the rocks. It comes out of the flying wave vortex, so it is named Canglang. Nowadays, three small reservoirs have been built up and down Canglanggou, and new attractions have been added.
