Introduction to Qin Daocheng: Donglian Qin Daocheng was built during the Qin Dynasty for two and a half years, starting from Jiuyuan (southwest of Baotou City today) to Ganquan (now Chunhua County, Xianyang) in the south. The road is thousands of years long. Eight hundred miles (700 kilometers), because the road is "straight through the mountains and valleys", it is called the "Old Qin Road" or "Eastern Qin Road City" in history.
