Where does the Great Wall start in the west and the east?

The Great Wall starts from Shanhaiguan in Liaoning in the east and ends at Jiayuguan in Gansu in the west. 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 history of the construction of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous allusion "bonfire plays princes" that happened in the capital Haojiang originated from this.

Great Wall resources are mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia, Xinjiang and other provinces, autonomous regions and municipalities. Among them, the length of Hebei province is more than 2000 kilometers, and the length of Shaanxi province is 1838 kilometers.

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.

In the two-way historical evolution, the military practical function of the Great Wall has gradually faded, and the role of cultural spirit has been continuously enhanced. Aesthetic charm is increasingly obvious. On the one hand, it constantly shows the wisdom and creativity of the Chinese nation to the world, on the other hand, it also shows the strong will and majestic spirit of mankind.
