I used to think that Langmu Temple was a temple. I did my homework before I left and found that it was actually a town on the border of Ganchuan Province, called Langmu Temple Town. A small stream one or two meters wide divided a town into two pieces, Sichuan and Gansu each. "Langmu Temple is a specific geographical name, which includes Langmu Temple Town under the jurisdiction of Luqu County, Gannan Tibetan Autonomous Prefecture, and Langmu Temple Village under the jurisdiction of Red Star Country in Ruoergai County, Sichuan Province. Langmu Temple is also a shorthand for Dacang Langmugeldi Temple, Sichuan Gelu Temple. In the Langmu Temple ditch there are two temples across the river: one is the Dacang Langmu Gedi Temple in Sichuan, and the other is the Saichi Temple in Gansu. The birthplace of Langmu Temple is the Grand Canyon of Langmu Temple in Sichuan, where Langmu Cave, Tiger Cave, and Bailongjiang are located.
