Three Sacred Mountains is located in Daocheng County, Garze Tibetan Autonomous Prefecture of Sichuan Province. From the meandering ranges, emerge the three sacred mountains of Daocheng: Xiannari, Yangmaiyong and Xianuoduoji. Since the ancient times, the three sacred mountains have been a sacred place for Tibetan Buddhism.

Xiannairi, the main peak of the three sacred mountains with an altitude of 6,032m, is first among Daocheng's high peaks. According to legend, it is the incarnation of the Buddhist Goddess of Mercy Guanyin or Avalokitesvara. Its slopes are vast; its gradient gentle, the mountain looks like Great Buddha sitting in peace, graceful and poised.
