"Yadan" is Uighur, the original meaning refers to a hill with a steep wall. In geology, the Yadan landform refers to a landscape composed of a series of parallel ridges and grooves after long-term wind erosion.

Dunhuang Yadan National Address Park is the end of the Dunhuang West Line, about 170 kilometers from Dunhuang City. The average tourist is to choose to charter a car or to report a day tour. When summer is over, there will be a lot of people, and the whole scenic spot is bustling. The sun is too hot, evaporating all the water on the surface, but even so, the source continues to get visitors to the sun. In winter, it seems to be much more desolate. The color of the Black Gobi has not yet been blackened, and there are few tourists in the scenic area. I walked in it and really felt the charm of nature.
