In the official history, the influence of Qin Shi Huang on transportation—that is, the content of the Qin Straight Road—is very brief, and only records the Qin Straight Road built by Qin Shi Huang for tourism, while ignoring the more far-reaching influence behind it.
However, modern scholars believe that starting from the Qin Linguang Palace, the Qin Straight Road traveled northward along the main vein of the Meridian Ridge to today's Dingbian County, then turned northeastward, passed through the Wushen Banner and Yijin Huoluo Banner in Inner Mongolia and Haiziwan in Dongsheng County, and finally reached the vicinity of Zhaojun's Tomb, crossed the Yellow River, and arrived at the Qin Jiuyuan County Governor.
When planning the Qin Straight Road, the ancients were mainly faced with two problems: the determination of the starting point and the end point, and the selection of the corridor belt.
When solving these two problems, the ancients mainly considered factors such as transportation location, military security, economic and cultural exchanges, natural conditions, and the level of technological development at that time.
At that time, the most important significance of Qin Zhidao was its military value.
It made it easier for Guanzhong to project troops and transport grain and grass to the northern border.
The reason why the corridor of the Gansu section of Qinzhidao was selected in Ziwuling was mainly due to the factors of military security.
During the Qin Dynasty, Xianyang was the political, economic, cultural, and military center of the country, which also determined that Xianyang must be the transportation center of the Qin Dynasty.
At the same time, the unification of the Qin Empire provided sufficient manpower and financial resources for the construction of the Qin Straight Road.
Qin Shi Huang first built the Great Wall, and later built the Qin Straight Road in order to maximize the role of the Great Wall.
The Qin Straight Road along the ridge can reduce the likelihood of being ambushed by the enemy on the march.
In the vast territory, only the southern Baiyue needed to continue the conquest, and the greatest threat to the north came from the Xiongnu.
Therefore, military security factors have become one of the main considerations in the selection of the Gansu section of the Qinzhi Road.
In general, the construction of the Qin Straight Road had both political, economic, and cultural needs, as well as military considerations.
During the Qin Dynasty, the lush vegetation in the Meridian Ridge area facilitated covert warfare, and the opening of the Qin Straight Road became an important means of controlling the river valley road.
Due to its commanding location, Meridian Ridge can control the valley avenues on both sides, thus effectively maintaining the safety of Kyoto.
In addition, in peacetime, Qin Zhidao was also used as a corridor for cultural exchange.
Qin Shi Huang used the Qin Straight Road during a tour of the Qin Dynasty during his eastern tour.
After that, the Qin Dynasty fell, and there is no large-scale record of the use of the straight road.
However, during the Western Han Dynasty, with the relaxation of Han-Hungarian relations, exchanges were carried out through straight roads many times.
The straight road was not only a major route for defense and commerce, but also spread the advanced technology and production tools of the Central Plains to the west.
Qinzhidao is one of the few ancient traffic artery sites preserved in China, and has important historical value.
The "Straight Road" is an ancient transportation route that connects China's Shaanxi Province, Gansu Province, and Ningxia Hui Autonomous Region.
For a long time, this route has been an important passage route for people, travelers and traders, as evidenced by the fact that a large number of ancient coins, waddang and other cultural relics from the Song Dynasty have been found on the straight.
Many sections of the Qin Straight Road are still passable today.
In particular, the Qinzhi Road, located on the Meridian Ridge, was once an important passage between Gansu and Ningxia.
In the "Zhengning County Chronicles" during the Qianlong period of the Qing Dynasty, it was recorded: "If this road is repaired, it will be able to open to traffic and lead to Kangzhuang."
In the Ming Dynasty, because the straight road could go directly to Yinxia, the merchants passed here.
With the shift of the political center, the traffic road pattern in the northwest region has changed dramatically since the Tang Dynasty.
However, the "straight road" still plays an important role in the economic exchanges connecting the provinces of Shaanxi, Gansu and Ningxia, and has been passed down to this day.
The construction of the Qin Straight Road connected the Guanzhong region with the Mongolian plateau, allowing the Qin Dynasty's policies and unification measures to be quickly conveyed to the foot of the Yin Mountains.
Advanced production techniques and tools are also able to spread beyond the Loop.
It can be said that in history, the "straight road" has played a positive role in promoting economic development and cultural exchanges, and is part of the Silk Road, and it is also the southern end of the grassland Silk Road.
