Dousha town 20 kilometers from the county seat of Yanjin County in the northeast of Yunnan is one of the important ancient passages linking Yunnan and Central China as early as the 3rd century BC.

For centuries, Dousha town has served as the first pass for those who entered Yunnan from Sichuan as one can see the existent Five-Chi passage that was built the Qin Dynasty (221 BC-206 BC). 

A pavilion named “Tang Bei Ting” has been built at Dousha Pass, where one could appreciate the cliff carvings by Yuan Zi, a procurator and famous calligrapher in the Tang Dynasty (618-907). On the opposite of the pavilion, one could further see the miraculous Suspended Coffins of Bo people.
