Introduction to Qinhuang Ancient Post Road: The history of Qinhuang Ancient Post Road can be traced back to the Qin Dynasty. It was once an important transportation pass from Yanzhao to Qin and Jin in ancient times, and the chokepoint that controlled the two provinces of Hebei and Jin. After Qin Shihuang unified China, he built a post road centered on Xianyang. The Jingxing Ancient Post Road was an important section of the main line at that time. This place is surrounded by mountains and the terrain is dangerous. It is the transportation hub between Shanxi and Shaanxi and Beijing, and it has been a battleground for military strategists of all ages.
