The Great Wall of Wan Li, China 1
The Great Wall, also known as the Great Wall of Wan Li, is an ancient military defense project 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 building the Great Wall can be traced back to the Western Zhou Dynasty, and the allusion of "playing princes by campfire" 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. 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.
