Abstract:

According to the narrate on Xuanzang’s smuggling out of the Yumen Pass from Guazhou recorded in “The Biography of Master Sanzang of the Daci’en Temple”, combined with studies on Soviet military maps and field investigations to carry out “accurate restoration”, it is determined that the site of Xiaowan City is the only possibility of the site of the Yumen Pass in the Tang Dynasty. A deserted beacon was discovered at the southern end of the Jieshanzi Valley, making it even more certain that this road was the route from Guazhou City to the Yumen Pass in the Tang Dynasty.

Key words: Yumen Pass, Xuan Zang, Suoyang County, Guazhou
