How many passes are there in the Great Wall of Wan Li?

Mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia, Xinjiang and other 15 provinces and cities.

The construction history of the Great Wall can be traced back to the Western Zhou Dynasty. At that time, Haojiang, the capital (now Xi 'an, Shaanxi), had a famous allusion-bonfire drama princes, which also 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 that people see today was built at this time.
