The Great Wall, also known as the Great Wall of Wan Li, was an ancient military fortress in China. It is a tall, solid and continuous long wall, which is used 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 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.
Importance of influence:
From the Qin and Han Dynasties to the Ming and Qing Dynasties, many passes along the Great Wall became places or centers for ethnic transactions 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 their exchange and complementarity.
