Tholing, Toling, Tuolin, or Toding, alternatively Zanda, Tsanda, Tsada, or Zada, is a town and seat of Zanda County, Ngari Prefecture, in the west of Tibet Autonomous Region, People's Republic of China. The town was the former capital of Guge Kingdom in western Tibet when it was ruled by Langdarma. Now an isolated military town, it has a well laid out new street, a post office, and telecommunication facilities. The Tholing Monastery, established in 997 AD, is in the suburbs of the town, in the Grand canyon of the Langchen Tsangpo. Historically, this was an important monastery; the second dissemination of Buddhism in Tibet emanated from it.
