The Road of Qin Dynasty was a military thoroughfare ordered by Qin Shihuang to be overseen and repaired by Meng Tian in 2 12 BC. With Xianyang as the center, it has 8 parts, passing through Ordos grassland and passing through 14 counties. The whole journey is more than 800 kilometers, passing through Gansu, Shaanxi and Inner Mongolia. In terms of width, the average width of Qin Zhi Road is over 20 meters, and the maximum width can reach 60 meters. It is a veritable ancient expressway. In the case of limited productivity in ancient times, its construction was not a spectacle, and the Qin Straight Road was also very important in the Qin Empire at that time.
1, the first is to resist foreign invasion. During the Qin dynasty, the Huns in the north were still eyeing up. Although the Great Wall prevented the Huns from going south, the transportation of grain, grass and military power between the Great Wall remained a huge problem. This straight Qin road just acts as a bridge. Qin Zhi Road intersects the Great Wall in a T-shape, so as to strengthen the connection between Guanzhong area where the capital of Qin Dynasty is located and Hetao area, and strengthen the defense capability of the Great Wall. It is conducive to resisting the Xiongnu in the north and making the Xiongnu afraid to go south.
2. Secondly, Qin unified the six countries to maintain the internal stability of the empire, but there were still unstable factors. The construction of roads played an important role in transmitting information and suppressing peasant uprisings to maintain the stability of the empire.
3. Finally, Qin Zhi Road has a certain positive effect on people's travel. The construction of Qin Zhi Road is conducive to the people's exchanges between the territories of Qin State, and also promotes the exchanges between the regions of Qin Dynasty.
Far-reaching, historical treasure. The function of the way of Qin dynasty is not only in the Qin dynasty. In the late Western Han Dynasty, in order to resist the invasion of Xiongnu, the Western Han Dynasty maintained and trimmed Qin Zhi Road to resist the invasion of northern forces. The shelf life of this expressway "Qinzhidao" exceeds 1000 years. After more than two thousand years of wind and rain, it was still in use in the Qing Dynasty. It can be seen that this expressway is of high quality and is really a treasure of the Chinese nation.
