If you want to talk about the most magnificent building in China, it is certainly the Great Wall. The Great Wall has a history of more than two thousand years, and no matter how the dynasties change, it will always stand there. In ancient times, there was no heavy machinery of the present, no sophisticated instruments and reinforced concrete, and the entire project was almost built by manpower, and it is not known how many lives were sacrificed during construction. Although the construction process was difficult, the Great Wall was not a large-scale construction project for qin shi huang for no reason, when the xiongnu in the north were rampant, and the great wall had a real function of resisting the outside world.
The Great Wall was not only a major project in ancient times, but is still a difficult project today. It is really too long, the easternmost all the way to Liaodong, the westernmost all the way to Gansu. The Great Wall existed long before Qin Shi Huang and was used to defend against foreign tribes, and before the Qin Dynasty, each country defended itself against foreign enemies and was built separately. After Qin Shi Huang unified the whole country, he connected these walls against foreign enemies, and the Great Wall has been connected ever since.
As a defensive measure, the Great Wall is certainly very difficult to break. Although there is a certain degree of damage to each enemy attack, it still exists after so many years. In fact, most of the walls we see now are the Ming Great Wall, but there is also the Qin Great Wall that still exists, and it can last so long, it must be very strong, which is unimaginable to people.
The Great Wall can be retained for so long, it can be seen that it is strong, and the difficulty of construction is certainly very unusual, it can be said that you are the best of the best, whether you are wall bricks or mortar. And the Great Wall can be preserved for so long, and the construction method adopted at that time is inseparable, so how is the Great Wall built in the end?
There was no cement at that time, so what did they build the wall? It turned out that Qin Shi Huang asked the craftsmen to add glutinous rice juice to the mortar. In fact, glutinous rice porridge is made of glutinous rice. The mortar made of glutinous rice is very viscous and very sticky, and the viscosity of glutinous rice mortar is far more than the current mortar, and it is this way of bonding that allows the bricks of the Great Wall to go through thousands of years without falling off.
Using glutinous rice juice as a building material is simply too luxurious. The production of grain in ancient times was very low, and there was not enough food to eat, and it was really very luxurious to use grain for construction. Even in modern times, it is estimated that people will not be willing to do it, this is simply a waste of food.
Although the Great Wall built by Qin Shi Huang can survive for a thousand years, although the Great Wall is strong, it can only defend against external enemies, and the collapse of internal people's hearts cannot be prevented. Therefore, in the strong city walls, it could not prevent the demise of the Qing Dynasty. It is ironic that the Great Wall, which was supposed to stabilize its rule, became a more rapid catalyst for the collapse of the Qin state. As the saying goes, "if you want to be outside, you must first be inside", the Qin state is not even stable internally, it wants to go outside, and its demise can be predicted
