There are endless layers of black technology in ancient times. Qin Shihuang's thoroughfare on the road is the road of people. After unifying the country, the road was built with great fanfare. The Qin Dynasty also became the first country to build a highway in history. Therefore, the Qinchi Road is also known as the ancient railway.

In 221 BC, Emperor Qin Shihuang unified the six kingdoms. The following year, he ordered the construction of a road that centered on Xianyang and led to all parts of the country. "Historical Records of the First Emperor Qin Shihuang" contains: "In the twenty-seven years, the first emperor toured the west and north of Longtau, came out of Jitou Mountain, and passed back to the middle. The fortune letter palace Weinan has already replaced the letter palace as a pole temple, like Tianji. Since The Jimiao Road passes through Laoshan Mountain (that is, Laoshan Mountain) and serves as the front hall of Ganquan. The Dao Road is from Xianyang. It is an old age, and it is given a rank of Jue.

There are 9 famous galleries, including Shangxian Road, which is now in Gaoling Tongshang County (Northern Shaanxi), Linjin Road, which passes through the Yellow River in Shanxi, and Dongfang Road in Henan, Hebei, and Shandong that passes through the Gugu Pass, and southeast of Shangluo Tong. Wuguan Road, the Qinling Road through Sichuan, the Long Road through Ningxia, Gansu, the Western Road, and the Chunhua Road through Jiuyuan.

From "Han Shu Jia Shan Biography", Qin Chi Road is flat, the road is fifty steps wide (about 69 meters today), a tree is planted every three feet (about 7 meters today), and metal cones are used on both sides of the road. It is thick and thick, and the middle part of the road is dedicated to the emperor's patrol line. It can be said that this is the earliest official national highway in Chinese history, and it is the exclusive lane of the emperor. Ministers, ordinary people and even relatives of the emperor have no right to go. The Qin and Han dynasties were the most popular, with a prescribed width of fifty steps and trees on both sides.

The first highway in the modern world was built in Germany in 1932. The highway doubled the German combat effectiveness. After the Second World War, Eisenhower was very surprised by the German combat effectiveness. After research, he discovered the Germans ’ wisdom. The German highway network and waterway network are connected, and within 24 hours, the German army can be sent from any place on the mainland to another. So after Eisenhower successfully ran for president in 1953, the American highway program began. At present, the four countries with the longest highway mileage in the world are China, the United States, Canada and Germany.

The construction of the Chidao is another feat that has exhausted the power of the Qin Dynasty, but the same rail is an indispensable moment for the unity of the Chinese people. Believe that anyone who knows a little bit about martial arts knows that this has the greatest strategic significance in the military. China's professional saying is called Binggui speedy, and German's professional saying is called flash strike.

Even today, the strategic significance of highways is still extraordinary. Nuclear missiles can be launched on highways, and fighter planes can take off on highways. This still inherits military ideas from more than 2,000 years ago.

All history is contemporary history. The milestone of infrastructure madness is once again standing on the top of the world.

Qin Shihuang was able to make such a move more than 2000 years ago, which shows that he has an extraordinary strategy. Qin Shihuang also contributed very much to China's development. Qinchi Road was used for more than 2,000 years and was an important transportation hub. A stunning project. Editor / Zhao Yongjing
