After Qin Shi Huang swept through the Six Kingdoms, he made many measures conducive to national unification, such as the unification of weights and measures in the same track as the book and the book, and these measures made many contributions to the development of the Qin state.
Although Qin Shi Huang implemented various favorable development measures for the development of the country during his reign, at the same time, he also used a large number of migrant workers to build the Great Wall, the Mausoleum of Qin Shi Huang and the Afang Palace, causing a lot of losses to the people. In addition, Qin Shi Huang also used a large number of laborers to build a major transportation road, the Qin Straight Road.
The development of qin straight
The construction of the Qin Straight Road began in 212 AD, and after the completion of this traffic artery, it provided a good transportation platform for the transportation of goods in the subsequent dynasties, and until the Qing Dynasty, the Qin Straight Road was still in use.
The QinZhi Road is a road from Yunyang to Jiuyuan County, with a total mileage of more than 700 kilometers. As for the reason why Qin Shi Huang ordered the construction of the Qin Straight Road, there are many different theories, perhaps to facilitate the tour, or to be specifically used to transport troops or to transport various materials.
The reason why the Qin Dynasty built straight roads
After the completion of the Qin Straight Road, it played a lot of major roles in the transportation of military materials for many later dynasties, and many generals led troops across the Qin Straight Road to the front line to resist the enemy. Emperor Wu of the Han Dynasty attacked the Xiongnu and Li Shimin against the Turks, both of which passed through the Qinzhi Road, which also recorded the cool and heroic posture of many ancient generals and soldiers who went to the battlefield to fight.
The times are constantly changing, the role of the Qin Straight Road has also changed, many places have been abandoned, and the Qin Straight Road that people can spy on is not particularly much at all.
Don't grow grass on the road?
When people once again opened archaeological exploration of the Qinzhi Road, the Qinzhidao, which had been devastated by wind, frost, rain and snow, had undergone great changes in the changes of the times, and it was somewhat incredible that there were almost no weeds on the surface of the Qinzhi Road.
It has been more than two thousand years since the Qin Straight Road was built, why has it been so long since the Qin Straight Road was overgrown with weeds? In order to know the secrets, archaeologists use instruments and equipment to test the soil layer of Qinzhidao.
The results of the test showed that the soil composition of The Qinzhidao was quite different from other soils, the saline and alkali content was higher, and the soil seemed to have traces of being burned by fire, and when these soils were squeezed with other tools, they would become unusually thick.
It seems that when Qin Shi Huang first ordered the construction of the Qin Straight Road, the structure and texture of the soil were changed, so that the soil environment was no longer suitable for the growth of plants. As a major project in the transportation of the Qin Dynasty, the Qin Straight Road must ensure that it can provide favorable conditions for the transportation of troops and goods at any time.
If the Qin straight road is full of weeds, it is not conducive to all kinds of vehicles to walk on it, and cleaning up weeds will also hinder transportation, so they have long thought of curbing the growth of weeds. So they made changes to the soil composition of the Qin Straight Road, destroying the soil and firing the ingredients, making it unfavorable to the growth of plants.
Therefore, archaeologists saw the Qin straight road that was hardly open to wild grass. Because Qin Shi Huang originally paid great attention to the construction of the Qin Straight Road and strictly controlled it himself, if he found that someone cut corners, the end would become very miserable.
epilogue
Judging from the construction process of the Qin Straight Road, the wisdom of the ancients is endless, although they did not have the current high technology at that time, many projects can only be completed by manpower, but the final completion is very good, and many buildings have been preserved to the present. With the rapid development of transportation, the former QinzhiDao has become a scenic spot, but the ancient traffic construction experience it has left for people has always influenced future generations.
