Why was the Great Wall made, and how was the Great Wall made

The Great Wall was developed from a castle and a fort. Castles and forts, which served as military defensive works, began as early as the end of the primitive commune.

Originally, it was to fight against the Huns.

In order for humans to be able to see from outer space in 2,000 years.

But it failed.

It's still too small, hehe.

The Great Wall is a great project in ancient China, and it is one of the representatives of the ancient Chinese military Li Xiang defensive architecture. The construction of the Great Wall lasted for thousands of years, starting from the Spring and Autumn Period and the Warring States Period, and finally ending in the Ming and Qing dynasties, after the construction and expansion of many dynasties, the total length of more than 10,000 miles.

The construction of the Great Wall mainly used stone, earth, brick, wood and other materials, of which stone and earth were the main materials. The construction of the Great Wall required a lot of manpower, material and financial resources, so the way and scale of the Great Wall were built in different dynasties. During the Spring and Autumn Period and the Warring States Period, the Great Wall was mainly built by various countries to defend against foreign enemies, and the scale was small, mainly using a combination of adobe walls and stone walls.

In the Qin Dynasty, after Qin Shi Huang unified the six kingdoms, in order to defend against the invasion of the northern nomads, he began to build the Great Wall, and connected the various city walls to form a Great Wall that was thousands of miles long. The Great Wall of Qin mainly adopts a combination of stone walls and rammed earth walls, with a grand scale and huge projects.

In the Ming Dynasty, the construction of the Great Wall entered a new stage. During the Ming Dynasty, the Great Wall was built mainly to defend against Mongol and Manchu invasions from the north. During the Ming Dynasty, the Great Wall mainly used a combination of brick and stone walls, which was more grand in scale and more complex in engineering.

The construction of the Great Wall during the Ming Dynasty not only required a lot of manpower, material and financial resources, but also required scientific design and exquisite technology.

In short, the construction of the Great Wall took thousands of years and was a great project in ancient China. The Great Wall was built not only to defend against foreign enemies, but also to be one of the symbols of ancient Chinese civilization. The construction of the Great Wall not only reflects the wisdom and diligence of the ancient Chinese people, but also reflects the outstanding achievements of ancient Chinese culture.

Maybe in everyone's impression, the Great Wall will have beacon towers, platforms and other fortifications, this is mainly the impression created by tourism now, the Great Wall we see in the scenic area has been repaired, and more TV series are also rendering in this direction, in fact, when it comes to the real role of the Great Wall, it is just a courtyard wall of the two big families of the Youchan farming people and the nomads, the farming people have built more, and the nomadic people are responsible for demolishing it, which is also the Inner Mongolia although it has the most Great Wall resources, There is one reason why there are very few left.

While we all now bemoan the demolition of the majestic Great Wall of Jin (built by Jin to defend against the Mongols led by Genghis Khan), the meaning is another interpretation from the perspective of ecological restoration and communication. Spike dust.

We know that the Great Wall is a fortification made by using the moat, through artificial changes, so that it becomes easier to defend and difficult to attack, of course, there must be the function of sentry and sentry, which is generally built with local materials, such as the Ming Great Wall near the mouth of the tiger, most of them are the Great Wall of earth, because there are not a large number of bricks and stones here, and the soil is not suitable for burning bricks, so the Ming Great Wall near the Qingshui River, no matter how majestic and magnificent, is the Great Wall of earth;

If you are fortunate enough to have been to the Great Wall of the Qin and Han Dynasties in Bayannur City, the Great Wall there is also built along the mountain range, it is said that Qin Shi Huang sent Meng Tian and Gongzi Fusu to build together, more like a "dry base" made of local materials, and now in the rural areas of the west, there is still such a custom, and most of their livestock pens are built with stones. I don't know if it's left over from that time.

Of course, in the Qin and Han dynasties, Juyan Gusai and Jilusai were also built with stone "dry bases", which were actually "courtyard walls" to separate the exchanges between the two ethnic groups in the past, and then sent troops to guard them in important positions in an attempt to prevent the northern nomads from coming.

Some people say that building the Great Wall is a waste of money and labor, it is better to be friendly, especially in the Qing Dynasty, the role of harmony has been brought to the extreme, and the princess's mansion is built on the grassland, the prince's mansion, and various summoning temples, everyone lives in peace and mutual benefit, and these courtyard walls are no longer needed, just like many parks and green spaces now, which used to be fenced, and now they have begun to open.
