It is equivalent to the post station of later generations. Archaeological excavations have proved that in the same year (101 B.C.) when Li Guangli and Dawan won the bloody horse, the Western Han Dynasty set up an important institution in Xuanquan, specializing in delivering official documents, mails, and receiving past officials and envoys - Xuanquanzhi. This Han Dynasty site was discovered in 1987. Since 1990, the cultural relics and archaeologists of Gansu Province have organized cultural relics and archaeologists to excavate it for two years. More than 20 sheets of hemp paper with Chinese ink marks unearthed in Xuanquanzhi have been identified as Chinese paper. This discovery pushed the time of the invention of paper in my country by nearly a century, and overturned the conclusion of Cai Lun's papermaking theory. It is the earlier paper discovered at home and abroad so far. The number of Han bamboo slips unearthed in Xuanquanzhi is staggering, with a total of more than 15,000 pieces. Its content is very rich, including edicts, judicial orders, post-booking books, cultural technology and other miscellaneous things. The connotation has expanded from the simple frontier garrison in "Falling Slips in Quicksand" to the administrative affairs of the border county, the postal business, the exchanges with the Western Regions, and the commercial activities. Other relics unearthed in Xuanquanzhi are also more precious, with a wide variety of agricultural tools, hunting tools, currency weapons, pottery clothing, grains, stone inkstones and brushes, etc. Although these relics have been preserved for thousands of years, they are still intact.
