The Great Wall, also known as the Great Wall, is a military fortification in ancient China, which is a tall, strong and continuous long wall to limit the movement of enemy cavalry. The Great Wall is not a simple isolated city wall, but a defense system with the city wall as the main body and a large number of cities, barriers, pavilions and beacons.
The defense engineering construction of the Great Wall has accumulated a wealth of experience in the construction process of more than 2,000 years. The Great Wall is not just a single city wall, but a complete defense engineering system composed of various fortifications such as city walls, enemy towers, gates, dungeons, camps, guards, and beacon towers in the town city. This defense engineering system is commanded and controlled by military command systems at all levels.
The Great Wall influences the significance.
From the Qin and Han dynasties to the Ming and Qing dynasties, many passes along the Great Wall became places or centers for ethnic trading in the two major economic and cultural systems of agriculture and animal husbandry, and some gradually developed into important towns along the Great Wall. The Great Wall not only ensures the normal development of agricultural economy, culture and animal husbandry economy and culture, but also provides a place and convenience for the exchange and complementarity between the two.
It also plays an important role in mediating the two economies and enabling the agricultural and animal husbandry economies to develop in the direction of mutual cooperation between the main and auxiliary industries. Therefore, the Great Wall not only played the role of separating the two economies and cultures, but also shouldered the important task of closely binding the two economies and cultures together.
In terms of culture, the Great Wall has also played an important role in the formation and development of the pluralistic and integrated pattern of the Chinese nation. The construction and defense of the Great Wall, as well as the battles in the Great Wall area, led to the extensive integration of the Han and more than a dozen ethnic minorities in ancient China.
