Han-Dynasty Bamboo Slips, Xuanquan Posthouse Site
From 1990 to 1992, Gansu Institute of Cultural Relics and Archaeology conducted archaeological excavations at the Xuanquan Posthouse Site, bringing to light a total of 70,000 artifacts including 35,000 bamboo slips. These bamboo slips represent a preserved portion of the archival documents generated from the daily operations at the Xuanquan Posthouse Site, with 18,000 pieces currently cataloged and organized. These slips provide detailed records of the organizational structure and operational status of the postal routes along the Silk Road during the Han Dynasty. As essential archival documents from a significant waystation serving interactions between the Han and the Western Regions, they contain over 30 geographical names from the Western Regions, referencing ancient kingdoms such as Yuezhi, Kangju, Jibin, Wuyishanli, and Tiaozhi. This rich information offers valuable insights into the exchanges between the Central Plains and the Western Regions during the Han Dynasty.
In 1990, slips containing The Book of Relay Stations and Distances (Slip No. II90DXT0214 A : 130) were unearthed at the Xuanquan Posthouse Site. The book records the postal traffic routes and stations of the Han Dynasty, along with their distances. The route begins at the eastern end in Cangsong of Wuwei Prefecture, passes through Wuwei, Zhangye, and Jiuquan, and terminates at the easternmost point of Dunhuang Prefecture, Yuanquan Posthouse. This slip documents a route that connects to the route recorded on Juyan Han-dynasty Bamboo Slip EPT59:582, forming a complete transportation route from Chang'an through Pingliang and Wuwei to Dunhuang Prefecture. It indicates the existence of nearly 60 waystations along the journey between Chang'an and Dunhuang, providing an authentic depiction of the historical landscape of the Silk Road segment between the two places.
