Speaking of the Great Wall, we will definitely think of Qin Shi Huang, Qin Shi Huang in architecture, can be called a "miracle", whether it is Afang Palace or qin shi huang mausoleum or terracotta warriors are called "world miracles", today's Great Wall is the same, the Great Wall is a defense against foreign invasion projects.
Since the 7th and 8th centuries BC, it has lasted for more than 2,000 years, with a total length of more than 50,000 kilometers, known as "more than 2,000 years up and down, more than 100,000 miles in length", such a vast project is not only in China, but also in the world is unique, but Qin Shi Huang was not the first person to build the Great Wall.
During the Spring and Autumn Period, the Seven Kingdoms were strong one after another, and all wanted to unify the Yellow River and the middle and lower reaches of the Yangtze River by force, but the Xiongnu in northern Shaanxi and northern Jin tended to be stronger, and they constantly plundered the northern borders of the three kingdoms of Qin, Zhao, and Yan, and there were Yiqu and Xiongnu in the north of the Qin State; there were Lin Hu and Lou Fu in the northwest of the Zhao Kingdom, and there were Ragged and Xiongnu in the north; and there was Dong Hu in the northern border of the Yan Kingdom.
They are good at riding and shooting, good at field combat, and the combat troops of the three kingdoms of Qin, Yan, and Zhao are infantry and chariots, slow to move, in order to restrain this passive situation, the Three Kingdoms have successively reformed, the Qin State Shang Martingale implemented the change of law, the Zhao State Wuling King nineteen years, the implementation of Hu costume riding shooting, the Yan State also recruited talents, the Three Kingdoms also successively built beacons in the north, and connected, which also formed the earliest Great Wall.
After the Three Kingdoms began to build the Great Wall, the rest of the countries also began to build, the South Great Wall was built by the State of Chu, the Great Wall of the State of Qi in the west from the northeast of present-day Pingyin County, Shandong, in 215 BC, Qin Shi Huang unified the world, the northern Xiongnu began to invade the territory, Qin Shi Huang in order to solve the problem, he ordered Mengtian to build the Great Wall, using nearly a million laborers.
It is precisely because Qin Shi Huang is too famous in history, so many people identify the Great Wall as built by Qin Shi Huang, but if you hold this psychological state, then what you see today is the "fake" Great Wall, the real Great Wall, maybe you did not find it at all.
Because the Great Wall we see now is the Great Wall of the Ming Dynasty, but this Great Wall is not called the Great Wall, called "Border City", after the establishment of the Ming Dynasty, the Mongolian nobles who returned to the desert steppe, the Tatar and Valar departments continued to harass and plunder in the south, in order to consolidate the northern border defense, in 1448, the Ming Dynasty began to build vigorously.
The Ming Great Wall starts from Liaoning Hushan on the banks of the Yalu River in the east, to Jiayuguan in Gansu in the east at the eastern foot of Qilian Mountain, and runs from east to west through ten provinces such as Liaoning, Hebei, Tianjin and Qinghai, with a total length of 8851.8 kilometers, in order to distinguish the Ming Great Wall and the Qin Shi Huang Great Wall, the Ming Great Wall is collectively known as the "Border City".
The real Qin Shi Huang Great Wall, in the 1561 AD Ningxia earthquake, the loss of 7788, only a little bit, although in cognition, the Great Wall is still built by Qin Shi Huang, but I have to tell you that the Qin Shi Huang Great Wall you see is fake.
The real Qin Great Wall is in the Liangtou of the Qinglong Gorge North Watershed and the Liangtou of the North Lotus Pond of Mutianyu, with a residual height of 2 meters, because they are all built of maoshi soil, so they have been preserved for a while.
