Located in Riwoqe County, Yiri is the most famous spring of the hot springs in Chamdo. It is surrounded by mountains, with green grass and wild flowers at the foot of the mountain, and thick forests on the mountain. The hot springs are distributed along a narrow zone of 100 meters, and six of the springs are serviceable with a water temperature 20-40℃. Because the water has an obvious curative effect on some diseases, it is greatly favored by those who suffer from rheumatic arthritis, bone fracture, semi-paralysis, calcium deficiencies and skin disease.
