Qin Shi Huang was the first monarch in China to be called emperor, and he was also known as the "Emperor of The Ages". However, at that time, it was very difficult to complete the great unification of this vast land of China, and he made a number of unifications for this purpose, among which one of the roads in the "Cultivation Road" did not grow weeds in 2200, which was amazing.
The "Chi Dao" is the earliest "national road" in Chinese history, which began in the Qin Dynasty. In 221 BC, Qin Shi Huang unified the six kingdoms, and in order to popularize his rule as soon as possible, he unified writing, currency, weights and measures, and ruts.
Before Qin Shi Huang unified the Six Kingdoms, the vehicle widths of the princely states varied, the lanes were wide and narrow, and the traffic between countries was very troublesome. After Qin Shi Huang ascended to the throne, he stipulated that the distance between the 2 wheels on the vehicle was changed to 6 feet, so that the distance of the wheels in the whole country was the same, which was called "the same track of the car". Now that the wheels are unified, the road for cars has become a must-change project.
So in 220 BC, he ordered the construction of chi roads centered on Xianyang and leading to all parts of the country, the most famous of which are 9. This measure is of great significance for the development of land transportation and the promotion of economic and cultural exchanges in various places.
However, at the beginning, the road was the emperor's special lane, and there were trees on both sides, which was very exquisite. The ministers, the people, and even his relatives below the emperor were not qualified to take the road.
Recently, in the mountains of Nanyang, Henan Province, it was surprising to find ancient rail (rail) roads. After carbon-14 dating, it was confirmed that it was a product of the Qin Dynasty more than 2200 years ago, and the most amazing thing is that this "highway" has not grown weeds today without being taken care of!
This "highway" is known as the Qin Straight Road. In the 35th year of Qin Shi Huang (212 BC), he ordered the construction of a road from Yunyang to Jiuyuan County, with a total length of more than 800 kilometers, which was a straight road for Qin. Until the Sui and Tang dynasties, it was still in use, and during the Qing Dynasty, the Qin Straight Road was gradually abandoned.
The Qin Straight Road is about 800 kilometers, passing through hills and valleys of various terrains, but the Qin Straight Road has few curves, they encounter mountains and split mountains, meet valleys and fill in valleys, all rely on people's hands to build this straight road.
Such a scale of highways, even today, the difficulty is very large, the widest part of the Qinzhi road surface is more than 60 meters, can parallel 12-15 cars, and even as a runway for medium-sized aircraft, it is a miracle.
The most powerful thing is that today, 2200 years later, the Qin straight road that has gone through ups and downs has actually been preserved, and most of the pavement is well preserved, and even no weeds grow! It attracted the attention of scientists, who came to Qinzhidao to conduct research.
It turned out that the soil on the Qin Straight Road was all "cooked soil" that had been fried by fire, and there was no nutrient on such soil, let alone weeds.
People can't help but sigh at the wisdom of the ancients, and their wisdom and sweat have allowed qin zhidao to be completely preserved for 2200 years, which is really admirable. Nowadays, the qinzhidao site has been listed as a national key cultural relics protection unit.
