Why are almost all the existing Great Walls the Ming Great Wall?

Because only the Ming Great Wall took the longest time and the quality of the project was excellent, it can still be well preserved. The Ming Great Wall was a military defense project built in northern China in the Ming Dynasty, also known as the side wall. In the process of construction, the materials used in Ming Great Wall are very similar to those used in Qin Changcheng, but they are quite different from those used in Han Great Wall and Qing Great Wall. The reason why the Great Wall was built at that time was to resist foreign invasion. In ancient times, it played a huge military role for our country. Then let's talk about the difference between the Ming Great Wall and the Han Great Wall.

The Great Wall was built in the Han Dynasty to resist the Huns. As we all know, Liu Bang beat the Huns in the early Han Dynasty, and then there was a siege of Deng Bai. At that time, Liu Bang had just unified the world and established the Han Dynasty. After such a huge failure, he is incapable of launching a large-scale war again. So it took Liu Bang about 70 years to build the Great Wall to resist the Huns.

During the period of Emperor Wu of the Han Dynasty, the construction of the Great Wall stopped. The reason was that Emperor Wu of the Han Dynasty defeated the Xiongnu at that time and had no chance to go south again. It was not until the Eastern Han Dynasty and the Three Kingdoms period that the nomadic people in the north formed a large tribal alliance, so the Great Wall was rarely built during this period. The reason why the Great Wall of Ming Dynasty can be preserved so far is that it took too long to build and the quality of the project was too good. Because the Great Wall of the Ming Dynasty was basically built after Zhu Yuanzhang unified the world, it has been like this for the whole 270 years of the Ming Dynasty.

After that, Judy moved the capital to Beijing after she ascended the throne. At that time, it was closer to nomadic people and there was almost no strategic buffer zone. Therefore, the Great Wall has become more important, and Ming Chengzu dare not be indifferent to such things. The Great Wall was basically not built in the Qing Dynasty. The Ming emperor was very keen on building the Great Wall, so the quality of the Great Wall is very good and can continue to this day.
