Plot Summary

The Great Wall is a miracle created by the laboring people in ancient China. Since the Warring States period, building the Great Wall has been a major project. According to records, Emperor Qin Shi Huang used nearly one million laborers to build the Great Wall, accounting for 1/20 of the country's population! At that time, there were no machines, all labor had to rely on human labor, and the working environment was steep mountains and steep cliffs. It can be imagined that without a large number of people working hard, it is impossible to complete this huge project. The important experience of building the Great Wall was to use dangerous barriers due to the terrain, which was affirmed during the reign of Emperor Qin Shi Huang. Sima Qian wrote it into the Records of the Grand Historian. In the future, every dynasty's construction of the Great Wall will be carried out according to this principle. Any construction of a city pass is right or wrong, and it is chosen to be located between two mountain valleys, or at the turning point of a river, or at a necessary point for the passage of flat rivers. This can not only control the danger, but also save manpower and materials, achieving the effect of "one man holding the pass, ten thousand men unable to open it". The construction of castles or beacon towers is also chosen in the "four important places". As for the construction of city walls, the terrain was fully utilized, such as the Great Wall at Juyongguan and Badaling, which were built along the back of the mountains. Some sections of the wall looked very steep from the outside, while the inside was very gentle, achieving the effect of "easy defense but difficult attack". In Liaoning Province, the Great Wall in Liaodong Town during the Ming Dynasty had a type called "mountain danger wall" or "split mountain wall", which used steep cliffs and walls to create the Great Wall with a slight cut. There are also some places that completely use dangerous cliffs and cliffs, Rivers and Lakes as natural barriers, which can be said to be an ingenious work. The Great Wall, as a great project, has become a precious heritage of the Chinese nation. On June 25, 2001, the Great Wall, as an ancient building from the Spring and Autumn Period to the Ming Dynasty, was approved by the State Council to be included in the fifth batch of national key cultural relics protection units. The total length of the Great Wall is about 12600 miles.
