Introduction to Panpo Pass: Panpo Pass is named after a military fortress. The reason is that Panpo is formed by eighteen turns. There are also Tibetan, Hui and Han nationalities living in harmony with each other. The Xialiang Market was built here. The pass is the only passage between the Gongtaizi Peak and the Mother Taizi Peak. It can be said that one man is in charge of the pass and no one can open it.
