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 actions.
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 story of the famous bonfire drama Prince, which took place in Haojing, the capital, and now Xi 'an, Shaanxi Province, originated here. 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.
For more than 2,000 years, the construction of the Great Wall in China has basically been recorded, but the names used in the construction and recording of the Great Wall in different dynasties and generations are different. Some of these different names are common to each other in the same historical period, while others are only used in a certain historical period or a certain region.
