Langmu Monastery is not only a name for a monastery, but also a name for a township. With Buddhist believers in a leisurely life style, the Langmu Monastery Town is located between Gansu Province and Sichuan Provice. A river, Bailong River, separates the township into two parts: one part in Gansu and another one in Sichuan.

In Tibetan language, Langmu means "fairy maiden". It got the name because many stones in the cave look like pretty girls. Besides, inside the monastery there is a tiger's den. So the Langmu Monastery can be translated as "a fairy maiden in the tiger's den".
