The Great Wall, also known as the Great Wall of Wan Li, is an ancient military defense project in China. It is a tall, solid and continuous long wall to limit the enemy's riding. The Great Wall is not a simple isolated wall, but a defense system with the wall as the main body and a large number of cities, obstacles, pavilions and landmarks.

The Great Wall is a miracle created by working people in ancient China. Building the Great Wall has been a big project since the Qin Dynasty. According to records, Qin Shihuang used nearly one million laborers to build the Great Wall, accounting for 1/21 of the national population. At that time, there was no machinery, and all the labor had to rely on manpower, and the working environment was steep mountains and deep cliffs. As you can imagine, this huge project cannot be completed without a large number of people working hard.

Great Wall resources are mainly distributed in 15 provinces, autonomous regions and municipalities such as Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia and Xinjiang.

Shaanxi province is the province with the most abundant resources of the Great Wall in China, with a length of 1,838km. According to the results of the national Great Wall resources survey conducted by the cultural relics and surveying and mapping departments, the total length of the Great Wall in Ming Dynasty was 8,851.8 kilometers, and the Great Wall in Qin and Han Dynasties and the early period was over 1,111 kilometers, with a total length of over 21,111 kilometers.

The length of the Great Wall

Due to its long history, most of the Great Walls in the early dynasties were incomplete, and the Great Wall built in the Ming Dynasty was relatively well preserved, so people generally refer to the Ming Great Wall, which means the length of the Great Wall.

National Cultural Heritage Administration and the State Bureau of Surveying and Mapping jointly announced on April 8, 2119 that the Great Wall of Ming Dynasty starts from Hushan in Liaoning in the east and ends at Jiayuguan in Gansu in the west, and passes through 156 counties in Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu and Qinghai from east to west, with a total length of 8,851.8km.. After a trench of 359.7 kilometers, the natural natural barrier is 2232.5 kilometers.
