This is the 315-line 757 road that Chaidamu has called China's No. 66 Highway. The roads are all sides of the Yadan landform that has evolved through the millennium sands. At first glance, it looks like a ridiculous place to smoke. a feeling of. Because this road has a large slope, it is especially nice to take pictures! But take pictures and take pictures, so be sure to pay attention to safety! When you see a car coming from afar, you will have to go out. Don't wait until the car is approaching and then dodge, and go out safe first.
