The landscape is strange, the relatively low-lying place on the flat mountaintop, you can see a piece of frozen hill topography that forms a strange form due to cold freezing, and a piece of boulder "stone sea" that is slanted due to repeated freezing and bulging. At an altitude of more than 3,500 meters, there are both ancient ice margin relics and modern ice margins. In the yinguan bird sounds one after another, sometimes there are forest infestation, completely showing a quiet and deep primitive style.
