Qin Shihuang built a road. Why hasn't he dared to grow weeds yet?

The reason for this magical phenomenon is mainly because the workers who built these roads at that time were all built with cooked soil. Because the soil quality of mature soil is more delicate than other soils, seeds are extremely difficult to grow in such soil quality. After a long time, there will naturally be no plants on this road. This road is Qin's straight road. At that time, Qin Shihuang ordered people to build roads in Inner Mongolia, Shaanxi and Gansu. But there is no record in the history books when this road was built. It is undeniable that this move by Qin Shihuang brought a lot of convenience to future generations. It can be said that until the Qing Dynasty, people used this road to transport materials. At that time, according to people's actual consideration, this road was always more than 800 kilometers, and there were traces of this road on many complicated terrains. At that time, in order to let people establish this way of Qin, it can be said that Qin people made a lot of efforts. Due to the terrain, this road encountered many difficulties in the excavation process. Even so, Qin people gradually solved these difficulties. Today, there are not any weeds on this road, mainly because people built it with ripe soil at that time.

Ordinary soil is burned and crushed, which becomes the main soil for building Qin Road, which is often called cooked soil. Those plant seeds don't grow in mature soil, so there are no weeds on the roads that have been successfully built for thousands of years. This strange phenomenon can reflect how superb the skills of ancient craftsmen were at that time. It stands to reason that the implementation of this project is very difficult, but at that time, Qin Shihuang did not take into account the actual situation of Qin State, and stipulated to those people that this road needs to be built in a very short time. Although later generations lamented the wisdom of the ancients, they also felt sorry for them. The ancients at that time must have accomplished this feat under great pressure of life.
