Emperor Wu of the Han Dynasty sent Zhang Qian to the Western Regions, which formed the basic trunk road of the Western Regions. It starts from Chang 'an in the Western Han Dynasty (Luoyang in the Eastern Han Dynasty) in the west and passes through Hexi Corridor to Dunhuang. Starting from Dunhuang, it is divided into two roads: South Road from Dunhuang passes through Loulan, Yutian and shache, passes through Qingji, now Pamir to Da Yue, rests in peace, and reaches Tiaozhi and Daqin in the west; The North Road runs from Dunhuang to Jiaohe, Qiuci and Shule, crosses Qingji to Dawan, rests in the west longitude and reaches Daqin. Its original function was to transport silk produced in ancient China. Therefore, when the German geographer Ferdinand von Richthofen first named it "Silk Road" in 1970s, it was widely accepted.
