Introduction to Yinhongtan: is the abbreviation of Yinsugeti River Red Willow Beach. The Yinsugeti River originates from the Yinsugeti Glacier in Crown Peak. There are large tracts of wild tamarisk forest on both sides of the river valley, and a variety of wild animals. There are many green grasses in summer, clear spring water, and cold water fish living in the water. The terrain here is flat and open, with ample water and grass, making it easy for people and camel teams to stop and rest, so it was chosen as a mountaineering base camp.
