Tianwan River runs through Kangding of Garze and Shimian of Ya’an in Sichuan. In early winter, its neighborhood takes on a magnificent look with diversely-tinted plants and towering snow mountains setting out each other. Originating in the south slope of Gongga Mountain, Tianwan River is the largest of all rivers in the mountain. It passes vigorously through more than ten peaks that stand over 5,000 meters above sea level. [Photo by Tang Li/Huang Gang/China.org.cn]
