The Great Wall, also known as the Great Wall of Wan Li, is an ancient military defense project in China. 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 ramparts, pavilions and landmarks. Why build the Great Wall? In which dynasty was the Great Wall built? In fact, the construction history of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous song "bonfire play" originated from the Great Wall.

During the Spring and Autumn Period and the Warring States Period, countries increased mutual defense, and the construction of the Great Wall entered its first climax. However, the construction time in this period is very short. After the Qin Dynasty unified the world, Qin Shihuang connected and restored the Great Wall during the Warring States Period, which was called the Great Wall of Wan Li. The construction of the Great Wall lasted nearly two thousand years, including the Western Zhou Dynasty, the Spring and Autumn Period, the Warring States Period, the Qin Dynasty, the Han Dynasty and the Northern Wei Dynasty.

Fan Wener:

The Great Wall is a great architectural project in ancient China and one of the miracles in the history of human civilization. The Great Wall now spans Tianjin, Heilongjiang, Jilin, Shandong, Henan, Qinghai, Xinjiang, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing, Liaoning and other 15 provinces, autonomous regions and municipalities directly under the central government, with a total length of about 2 1 196. 18km.

Some people may ask, how was such a huge project built? The bottom of the Great Wall is made up of countless stones weighing two or three pounds. Because there were no advanced machines in ancient times, we could only rely on countless working people to stretch out their hard-working hands, carry a stone step by step with generous shoulders, climb steep mountains, and then slowly build the Great Wall.

Now we are at the foot of the Great Wall. This section of the city is built on Badaling. It is tall and strong, made of huge stones and city bricks. The top of the city wall is paved with square bricks, which is very flat, like a wide road, and five or six horses can walk side by side. There are rows of buttresses more than two meters high along the outer edge of the city wall, and there are square observation ports and shooting ports on the buttresses for observation and shooting.

On the top of the city wall, there is a square platform every 300 meters, which is the fortress of the garrison. When fighting, platforms can echo each other. Now that we are standing on the Great Wall, standing on the square bricks under our feet and holding the stones on the wall, you will naturally think of the working people who built the Great Wall in ancient times.
