叶尔羌河
The southern part of Akto County is the northern slope of Kunlun Mountains, which is the main mountain of the Kunlun. In addition to the Jogori Peak, the other three famous peaks of Muztagh Ata, Kongur Tagh and Kongur Tiube are almost all in Akto. Kunlun is famous for its jade production. It is located in the mountains of Akto in the upper reaches of the Yarkand River. There are many jade mines. These jade stones exposed in the rock formations by the river are washed into the riverbed in the lower reaches by water, and stepping on jade in the Yarkand River has become a production activity and industry that the locals have been engaged for thousands of years.
