I just think I should. As early as the Spring and Autumn Period in the 7th century BC, the Chu State was the first to build a defense against invasion by other countries"Chu Fang City"It opened the curtain on the construction of the Great Wall in Chinese history. During the Warring States Period, Qi, Wei, Zhao, Qin, Yan and Zhongshan were also built one after another"The princes defended each other on the Great Wall"。
Among them, the three kingdoms of Qin, Zhao and Yan were adjacent to the Xiongnu, a powerful nomadic people in the north, and at the same time as the Great Wall of the princes defended each other, they were also built in the north"The Great Wall of Hu is rejected"。
After the unification of Qin, the Great Wall that isolated the countries was abandoned, and the Great Wall on the northern border of Qin, Zhao and Yan was connected, expanded and repaired, forming a Great Wall for the first time from Lintao in the west to more than 10,000 miles in the east of Liaodong, and the Great Wall of Wanli appeared.
The Great Wall is the greatest military defense project in the ancient history of the world, it is not a simple isolated first-line city wall, but from point to line, from line to surface, the passes, military forts, gates and military towns along the Great Wall are connected into a tight network to form a complete defense system. At the same time, a large number of enemy platforms and beacon towers were built along the Great Wall, which effectively improved the defensive combat capability and military communication capability of the Great Wall.
The Great Wall was the guarantee of peace and stability in ancient China's agricultural society. In the long history of more than 2,000 years, the rulers of successive dynasties have repelled the invasion of the northern nomads many times by virtue of the Great Wall, created a relatively flat production environment for the survival and development of the agricultural economy in feudal society, and also made the people's lives more stable.

I think it's a matter of neutrality. The good thing is that we have richer Chinese characteristics, but the bad thing is that it was built with the lives of many people! So, it should, it should be, it shouldn't, and it makes sense.
-
No, because it is not cost-effective to spend too much manpower and material resources, and if there are bullets, is this kind of project still meaningful?
-
Of course it should be, the traditional way of defending the country in ancient times.

The Great Wall is a very great project in ancient China, and its construction took thousands of years. The construction of the Great Wall began in the Spring and Autumn Period and the Warring States Period, and was rebuilt and expanded in the Ming and Qing dynasties, with the purpose of defending the country against foreign invasion. The construction of the Great Wall has a special historical background and construction conditions, which are described in more detail below.
The construction of the Great Wall began during the Spring and Autumn Period and the Warring States Period, when the first side of the Zhou Chan Dynasty in China was in constant turmoil and there was a constant threat of national invasion. In order to defend themselves against these invaders, the vassal states began to build walls and fortresses to defend their lands. Over time, these walls gradually joined together and became the Great Wall built by the people who came before them.
The main building materials of the Great Wall were stone, loess, and brick. At that time, the construction technology was relatively rudimentary, so when building the Great Wall, many workers used manual labor to transport heavy objects such as stones. It was a very difficult job, and many workers sacrificed their lives.
However, the construction of these high walls has made China's borders much safer. For thousands of years, the construction of the Great Wall continued, from a small city wall, to the entire defense line of China, until the Ming and Qing dynasties.
Although the construction of the Great Wall has gone through a lot of painstaking work, it has also brought some benefits. The Great Wall brings more security and morale to the Chinese people, while also increasing the convenience of communication and the spread of culture. Up to now, the Great Wall has become one of the famous 1080 scenic spots in China and an important cultural heritage of the whole of China.
To sum up, the Great Wall was built by people of many Chinese dynasties with hard work and wisdom over thousands of years. As a very great project in Chinese history, the Great Wall demonstrates the high construction technology and governance capabilities of ancient China. It has historically carried the spirit of the Chinese people's struggle and defense of their homeland, and Qi Zhengzhi is still admired and admired by the people of the world.

How the Great Wall was built:
First of all, the construction of the Great Wall requires a lot of manpower and material resources. In ancient times, in order to build the Great Wall, various dynasties mobilized a large number of laborers and soldiers, who not only had to perform heavy manual labor, but also had to endure harsh living conditions and harsh natural environments. In addition, in order to build the Great Wall, a large number of building materials such as stone, wood, earth and stone were also required, and these materials needed to be transported from afar, which increased the difficulty and cost of construction.
Secondly, the construction of the Great Wall requires sophisticated design and construction techniques. In ancient times, the design and construction of the Great Wall was carried out by specialized engineers and architects, who needed to take into account various factors such as topography, climate, and the need for prevention and resonance to formulate a reasonable design plan. During the construction process, they also need to use a variety of tools and techniques, such as stone hammers, rope slides, pulleys, etc., to complete the complex construction tasks.
Finally, the construction of the Great Wall requires a strong will and perseverance. The construction of the Great Wall took hundreds of years, during which there were many wars and political upheavals, but each generation of architects and migrant workers firmly believed in their mission and worked hard to complete this great project.
In short, the construction of the Great Wall is a great project in ancient China, which requires a lot of manpower and material resources, meticulous design and construction techniques, and firm will and perseverance. The construction of the Great Wall is not only an outstanding representative of ancient Chinese civilization, but also a great achievement in the history of human civilization. <>

The Great Wall is a magnificent project built in ancient China, which not only has the role of defense, but also shows the civilization and wisdom of ancient China. The construction of the Great Wall lasted thousands of years and is an outstanding representative of ancient Chinese engineering. So how was the Great Wall built?
Let's take a look.
Preparations. Due to the vast area of the construction of the Great Wall, which involves many people and people, a lot of preparatory work is required before the construction of the Great Wall. First of all, it is necessary to conduct a survey, determine the construction location according to the topography, slope, mountains and rivers, etc., and then need to prepare materials, such as stones, earth, wood, etc.
At the same time, it was necessary to organize a large number of laborers, including soldiers, migrant workers, and prisoners.
How it was built. The Great Wall was built in a variety of ways, from imposing masonry structures to wooden moats dotted on lofty mountains. Among them, the most typical are the rammed earth method and the masonry structure method.
The rammed earth method refers to the rammed earth wall by ramming materials such as clay, stone and mud with sticks; The masonry method refers to the construction of walls with stones or bricks, and the walls are divided into three types: single arches, urn cities, and fortresses.
Efforts and resources. The construction of the Great Wall cost a lot of manpower and material resources. Historically, there were three main types of labor involved in the construction of the Great Wall:
Army, laborers, and prisoners. Soldiers were responsible for defense and management, migrant workers were responsible for carrying and tamping earth and stones, and prisoners were forced to participate in the construction of the Great Wall. In terms of materials, the work required to build the Great Wall involved a large amount of building materials and food, so it was necessary to rely on supplies from many sources.
Technical features: The construction techniques of the Great Wall have unique characteristics, the most special of which is the rammed earth method. The biggest feature of the rammed earth method is that it is durable, and it is very convenient to use, which can promote the progress of repairing the imperial reputation.
In addition, many other techniques were used in the construction of the Great Wall, such as multi-perspective surveys and clay stamping bricks, which made the Great Wall an outstanding example of early construction.
Conservation work. After the construction of the Great Wall was completed, conservation work was needed to ensure its long-term preservation. In the protection work, it mainly includes anti-corrosion, earthquake-proof, reinforcement and other aspects.
Among them, earthquake prevention is the top priority of the protection of the Great Wall, because China is located in the ** belt, and the tremor at ** may cause safety problems on the Great Wall.
Summary. The construction of the Great Wall is an outstanding representation of Chinese culture and history, and at the same time a testament to the extraordinary engineering technology of ancient China. The construction of the Great Wall originated from the need for war defense and developed into the later commercial **, the Great Wall is the ruins of a long process with thousands of years as the time scale.
It has had a profound impact on China's cultural, political, military, economic, and technological development.

In the early days, the Great Wall was built using local materials, i.e., rammed brick walls. This is the same method used to build dwellings: two rows of planks are erected to form two sides of a wall, and then the earth is poured into the sealed planks in layers, and then it is tamped.
The planks are on average 4 meters long and can hold 80 cubic meters of earth. This made it possible to produce a layer of bricks 8 10 cm thick, although it was later found that there were also layers of bricks 3 20 cm thick. Sometimes, a thin layer of reeds is sandwiched between the soil layer to speed up the drying process of the bricks.
In the Gobi Desert and steppe areas, the construction of the city walls was based on local plants. Fifteen centimeters of red palm leaves or reeds were mixed with a not-so-thick layer of pebbles and earth to create a brick wall with a local character. In the Tarim Basin, the walls were built with large bundles of shrubs, poplar trunks mixed with tamped adobe.
An important feature common to all walls is that each layer is rammed hard and then another is rammed. The durability of this type of construction can be seen in the few sections of the wall that have been preserved. These sections of the wall were built in 656 BC.
In the north of Zhongkuang, the Qin city wall from 300 BC is still 3 meters high. The bottom of the wall is meters wide, and the upper part of the wall is meters wide, and it is made of yellow mud and a small amount of rubble rammed. In Gansu, the 4-meter-high Han city walls are preserved, including one of the largest fortresses at Wangmen Pass.
The bricks of the walls are staggered at the corners, and the square gates are narrow at the top and wide at the bottom, which prevents the walls from collapsing. In this area, there are also more than 100 beacon stations. They were built either of rammed adobe or of sun-dried bricks.
On these sections of the city wall, every 1600 2500 meters, there is a beacon tower with a width at the bottom and a narrow tower at the top, with an area of 17 square meters at the bottom and a height of 25 meters. On the wall of the beacon. There are also obvious traces of scaffolding.
Most of the Great Wall was built during the Ming Dynasty, when some new methods of construction emerged. The western section of the Great Wall is still built according to the traditional method. But in order to protect the capital Beijing from the Mongols and Manchus, its eastern section was made of stone and bricks, and its foundations were made of compacted earth or gravel.
Other fortresses, such as Shanhaiguan, are built like a small castle. There are bunkers and shelters for preparing for war, drawbridges for opening and closing, training grounds for training soldiers, and warehouses for war readiness. There is also a hay field outside.

As a defensive project, the Great Wall is mainly composed of three parts: passes, city walls, and beacon towers.
1. Pass:
The pass is generally composed of a square or polygonal city wall, a city gate, a city gate tower, and an urn city. There are also Luo Cheng and Guess Xiao Moat. Among them, the city wall is the main project of the Great Wall, and the inner and outer eaves walls are mostly covered with giant bricks and stones, filled with loess and gravel, and the height is generally about 10 meters.
The top is 4 5 meters wide, and there are horse paths and stairways for the upper and lower city walls. On the outer eaves of the city wall, there are battlements for lookouts and shooting, and on the inner eaves wall, there is a wall (or women's wall) about 1 meter high.
2. City wall: The city wall is the link that connects Xiongguan, passes, enemy platforms, etc. The average height is about 7.8 meters, and in places with steep hills, the walls are relatively low.
The average width of the wall base is about one meter, the top is wide one meter, and the section is small and large into a trapezoid. The wall knots mainly include plate rammed earth walls, adobe walls, brick walls, etc. Other structural facilities are:
Coupon door. Battlements. Castle Tower.
3. Beacon:
The beacon tower is a building that uses beacon fire and smoke to transmit military information.
