Only the remains of the Great Wall of Qin remain. Qin Shi Huang mobilized 300,000 people to build the Great Wall, creating a miracle in the history of human architecture. The construction of the Great Wall objectively played a positive role in preventing the southern invasion of the Xiongnu and protecting the economic and cultural development of the Central Plains.

Among them, thousands of miles away, there are the Great Wall of Qin, the Great Wall of Han and the Great Wall of Ming.

3. The project is huge

According to the rough calculations of scientists, if a wall of 1 meter wide and 5 meters high is built from the earth, bricks and stones of the Great Wall of the Ming Dynasty, it can go around the earth; If it is used for laying meters of thickness and width of 5 meters. This path can circle the earth up to three times.

Length. Due to the age, most of the Great Wall of the early dynasties are incomplete, and the Great Wall built in the Ming Dynasty is relatively intact, so people generally refer to the Great Wall of the Ming Dynasty, and the length of the Great Wall is the length of the Great Wall of the Ming Dynasty.

On April 18, 2009, the State Administration of Cultural Heritage and the State Bureau of Surveying and Mapping jointly announced that the Great Wall of the Ming Dynasty stretched from Hushan in Liaoning Province in the east to Jiayuguan in Gansu Province in the west, and traveled from east to west through 156 counties in ten provinces (autonomous regions and municipalities directly under the central government) of Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu and Qinghai, with a total length of kilometers. After thousands of kilometers of trenches, the natural natural danger is kilometers.
