Introduction to the Straight Road: The Sage-Qin Dynasty Ancient Road is one of the two world-famous projects after Qin Shihuang unified the six kingdoms. "Sage Expressway" is more than 1,800 miles long and is known as the earliest expressway in human history. The famous stories in history of Wei Qing and Huo Qubing's northern expedition to the Huns, Su Wu's mission to the Huns, Zhaojun's departure from the fortress, and Wenji's return to the Han Dynasty all happened on this ancient road. This ancient road in the scenic area is 3.6 kilometers long and 30 meters wide. On both sides, some military buildings and civilian facilities such as beacon towers, passes, and post stations have been restored.
