Mentioned the great projects of ancient China. The Great Wall is undoubtedly one of the greatest projects. Most of the Great Walls that everyone sees were built in the Ming Dynasty. In fact, the history of ancient Chinese building the Great Wall can be traced back to the Western Zhou Dynasty. In the Western Zhou Dynasty, everyone had heard the story of King Zhou You's "Feng Huo Opera Princes", which shows that the Great Wall, which played a role of military defense, had already been built at that time. During the Spring and Autumn and Warring States period, the princes fought and the princes in the north faced the intrusion of ethnic minorities. Therefore, countries like Yan, Qin, and Zhao all built the Great Wall from the perspective of their own security. After Qin Shihuang achieved great unification, he carried out repairs on the basis of the Great Wall of the Warring States, and it became known as the Great Wall.
The Great Wall is a super fortification of the Qin Dynasty and a symbol of five thousand years of civilization and wisdom of the working people in ancient my country. During the Qin Dynasty, the high mountains and ridges where the Great Wall of China was located separated the inside of the pass and the outside of the pass. The geographical environment inside the pass was relatively more suitable for living and farming. However, there were obvious production seasons and labor limitations outside the pass. The nomads will vigorously cross the lofty mountains and looting the rich areas in the pass!
The people engaged in farming work are naturally weaker than the nomads who wandered on horseback for a long time, so they can only watch the destruction of their carefully constructed homes. In the long run, this incident has caused Qin Shihuang’s concern, so he deliberately defended his people, and began to build the great construction of the Great Wall!
The Great Wall has a total length of more than 6000 kilometers and is a rare defense project in human history. So how much would it cost to build such a huge project in ancient times when productivity was lagging behind? How much is it now? The Great Wall has an average height of 7.8 meters and a base of 6.5 meters wide. It is basically constructed of blue bricks and mortar. I believe many people will be interested in this topic.
It takes about 6000 green bricks and 7 cubic meters of mortar to build a one-meter Great Wall, a blue brick costs 4 yuan, and a cubic meter of white mortar about 400 yuan, plus machinery Cost, management cost is about 2,000 yuan, five-day labor cost is 30,000 yuan, it can be estimated that it will cost about 60,000 yuan to build a one-meter Great Wall, then it will cost more than 360 billion yuan to build a wall of more than 6,000 kilometers.
In addition, the Great Wall has a total of 60,000 enemy buildings, which is also a considerable amount of expense. The cost of each enemy building is about 200,000 yuan, and 60,000 enemy buildings. The floor is 12 billion yuan. Coupled with the cost of important passes such as Shanhaiguan and Jiayuguan, it is estimated that there will be nearly 100 billion yuan. The entire Great Wall will cost about 472 billion yuan. Such a huge cost, even if it is put now, can be said to be a super project.
Its total cost is approximately equal to the sum of the three projects of our country’s current Hong Kong-Zhuhai-Macao Bridge, Jiuquan Wind Power Plant and Three Gorges Dam. To this day, the Great Wall is still Standing on top of the mountains, it is not only a symbol of Chinese civilization, but also a miracle in human history.
