The Great Wall, also known as the Great Wall, is an ancient Chinese military fortification, a tall, strong and continuous long wall, used to limit the movement of enemy horses. 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, barriers, pavilions and landmarks. According to the Great Wall formed the Great Wall culture.
The history of the Great Wall can be traced back to 5000 years ago. Later, around 200 BC, after the state of Qin destroyed the six States and unified the world, Qin Shihuang connected and repaired the Warring States Great Wall, which was called the Great Wall. The Ming Dynasty was the last dynasty to overhaul the Great Wall, and most of the Great Wall that people see was built at this time.
The Great Wall resources are mainly distributed in 15 provinces, autonomous regions and municipalities directly under the central government, including Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia and Xinjiang. Among them, the length of Hebei Province is more than 2,000 kilometers, and the length of Shaanxi Province is 1,838 kilometers. According to the results of the national survey of Great Wall resources by the Department of Cultural relics and Surveying and Mapping, the total length of the Great Wall in the Ming Dynasty is 8,851.8 kilometers, and the Great Wall in the Qin and Han Dynasties and the early period is more than 10,000 kilometers, with a total length of more than 21,000 kilometers. The existing Great Wall cultural relics include all kinds of remains of the Great Wall, trenches, boundary trenches, single buildings, gateways, and related facilities, totaling more than 43,000 (blocks/sections).
