【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.
