The Great Wall of the Yangtze River and Huangshan Mountain of the Yellow River are the lyrics of a song. In the hearts of our people, the Great Wall is a spiritual symbol and will never give up. However, it is also true that the Great Wall still stands there after thousands of years. As a historical symbol of Chinese civilization for thousands of years, it is also an excellent proof of China's architectural technology.

As eight wonders of the world, the Great Wall is by no means a hollow reputation. The Great Wall embodies the efforts and wisdom of many people in China, and our ancestors even paid precious lives. Although many of them are involuntary, they can still reflect the hard work of the ancient working people. It was the hard work and wisdom of our ancestors that built this ancient civilization for us. This is a symbol of which we can be proud. When we tell the world that our Chinese civilization can have such a tangible proof, it also makes everyone proud.

The Great Wall was built in the Qin Dynasty. It has a history of more than 2000 years. How did the craftsmen at that time come up with the idea of building such a strong wall? For the time being, building such a huge project. It's also hard. New research has found that the Great Wall is so strong, which is a surprising reason. This is the crystallization of the wisdom of many working people.

At that time, tens of thousands of laborers were needed to build the Great Wall, and the amount of labor per laborer was unimaginable. As for the quality of this project, there is no problem at all. At that time, the labor force was unambiguous, and people with architectural knowledge were transferred from all over the country. This is also the result of many people's efforts.
