"You are not a hero if you don't get to the Great Wall." As one of the landmark buildings in China, the Great Wall is mentioned by Chairman Mao in many poems. And Qin Shihuang, who built him, is also a topical figure in ancient history. In ancient times, there were no such things as reinforced concrete. What materials did Qin Shihuang add to the Great Wall when he built it, so that the Great Wall could stand for 2,000 years and not fall down ?

1. The role of the Great Wall =============================

First of all, we need to know the role of the Great Wall. Qin Shihuang didn’t build it for good looks. Although the Great Wall is a tourist attraction today, it focuses on the protection of cultural relics, but at that time, the Great Wall was actually built as a military defense project !

Here I have to talk about the "beacon fire show princes", the beacon tower on the Great Wall is a little bit of wolf smoke, the princes all came to rescue, and they acted very quickly. Although this incident is about a faint king, it can be seen from the side that the beacon tower is used for Communication is fast and broad .

But wasn't the Great Wall built by Qin Shi Huang? Did the Zhou Dynasty already have the Great Wall? Yes, now when we talk about the Great Wall, we generally refer to the Great Wall built by Qin Shihuang, but it is true that the Great Wall was built to defend against foreign enemies during the Zhou Dynasty . Only after Qin Shi Huang began to build the Great Wall on a large scale to protect border security.

Qin Shihuang was an ambitious emperor. He knew that it was more difficult to defend the country, but at this time, he mainly focused on dealing with foreign risks. After Qin Shihuang built the grand and majestic Qin Great Wall, almost all dynasties built and fortified the Great Wall , and the Great Wall was also the main base for retreating and attacking in historical wars.

2. Raw materials for building the Great Wall ============================================

Now when we go to the Great Wall, we can see that the Great Wall is mainly made of stone bricks, but at that time there was no cement and no steel bars, not to mention that 6,000 stone bricks were needed for one meter of the Great Wall . What about down?

It is definitely not possible to use ordinary mud. To make the Great Wall hard enough to resist foreign enemies, special materials must be added to it. This problem was finally overcome by the ancients, and now we can still see such a majestic wall. The Great Wall is the best proof of their wisdom.

The original material used to connect the stone bricks is called glutinous rice mortar king. As the name suggests, this kind of mud contains glutinous rice . After adding this material, ordinary mud has hardness and viscosity comparable to cement, but it also consumes a lot of Sticky rice. In addition to this kind of mud, the main material for the construction of the Great Wall - brick, Qin Shihuang also set strict standards. Once the bricks produced are unqualified, the workers will be killed .

In addition, because the Great Wall ordered by Qin Shihuang spanned many places, it was very unrealistic to transport materials back and forth, so Qin Shihuang decided to choose materials according to local conditions . For example, the Great Wall in the Yumen Pass area has few loess resources, and transporting loess from other places will delay a lot of time and consume a lot of manpower.

However, there are two materials that are particularly sufficient in this place, that is, reeds and gravel , so these two materials were added when building the wall of this section of the Great Wall, and the built wall is also very strong.

Three, mixed reputation

The construction of the Great Wall undoubtedly greatly improved the national defense capabilities of the Qin Dynasty, but Qin Shihuang had spent a lot of manpower in building the Great Wall. Many men were arrested to build the Great Wall, and then buried their bones under the Great Wall. Therefore, sensual people will say that the Great Wall is Built with the blood and tears of countless working people.

It is true that Qin Shi Huang had just established himself as the emperor at this time, and while vigorously solving foreign problems, he ignored the common people who survived under his strict requirements , causing a lot of internal worries. After the construction of the Great Wall, Qin Shi Huang began to build mausoleums and terracotta warriors, which was undoubtedly worse for the common people. Before he could breathe out, he would be arrested to work as a coolie, which made life difficult for the people, and countless families were destroyed as a result.

The story of "Meng Jiangnu cried down the Great Wall" is familiar to everyone. From the beginning, Meng Jiangnu was sad because of her husband's death, and gradually spread that she cried down the Great Wall and accused Qin Shihuang. It can be seen that people at that time could not understand Qin Shihuang, who built the Great Wall. The practice, and even wish it collapsed, it can be seen that Qin Shihuang has gradually lost popular support .

Qin Shi Huang's harsh rule, coupled with the incompetence of Qin II, led to the demise of the Qin Dynasty after only two generations. However , the Great Wall built by Qin Shihuang played a very important role in later generations. The materials and methods used in the construction also allowed the Great Wall to stand for 2,000 years and not fall down , allowing us to see the wisdom and hard work of the ancient working people. Other than that, this is indeed one of Qin Shi Huang's contributions.
