Yumen Pass, Dunhuang, Gansu 甘肃敦煌玉门关
The site of Yumen Pass, known locally as Xiaofangpan Fort, stands in the gobi northwest of Dunhuang, Gansu. The pass was set up on the western frontier under Emperor Wu of Han – its name, Jade Gate, is said to come from the jade brought in this way from the Western Regions – and with Yang Pass it was a gateway to the west; Wang Zhihuan’s line “The spring wind does not pass the Jade Gate” made it famous. The site is a component of the World Heritage Site “Silk Roads: the Routes Network of Chang’an-Tianshan Corridor”.
