The history of the construction of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous allusion "bonfire drama princes" occurred in Haojing, the capital (now Xi 'an, Shaanxi) originated from this. During the Spring and Autumn Period and the Warring States Period, countries competed for hegemony and defended each other, and the construction of the Great Wall entered its first climax, but the construction length at this time was relatively short. After Qin destroyed the six countries and unified the world, Qin Shihuang connected and repaired the Great Wall of the Warring States Period, which was called the Great Wall of Wan Li. The Ming Dynasty was the last dynasty to overhaul the Great Wall, and most of the Great Wall seen by people today was built at this time.
According to the results of the national Great Wall resources survey conducted by cultural relics and surveying and mapping departments, the total length of the Great Wall in Ming Dynasty was 885 1.8km, and it was more than 1 1,000 km in Qin and Han Dynasties and its early period, and the total length was more than 2 1 1,000 km. The existing cultural relics of the Great Wall include the Great Wall, trenches/trenches, single buildings, customs castles and related facilities, totaling more than 43,000 places (blocks/sections).

Military influence of the Great Wall:
The Great Wall is the greatest military defense project in the ancient history of the world. It is not a simple isolated first-line wall, but from point to line, from line to surface, connecting the passes, military fortresses, Guancheng and military towns along the Great Wall into a tight network, forming a complete defense system. The system of military fortress, Guancheng and military town has many functions, such as fighting, command, observation, communication, concealment and so on, and it is equipped with point, line and surface defense engineering of the resident army.
The military defense thought embodied in The Great Wall occupies an important position in the history of military development. The birth and development of the Great Wall is in step with the whole military development in ancient China, which is of great significance to the study of the formation and development of ancient military operational thought. Qin Huang and Wu Han, including the early Ming Dynasty, built the Great Wall when they took the initiative to attack and gained overwhelming military superiority. It can be seen that building the Great Wall is not only an active defense, but also a strategy of accumulating strength and continuing to forge ahead.
