The Great Wall is one of the eight wonders of the world and a representative of ancient Chinese architecture. After the unification of the Six Kingdoms, Qin Shi Huang began to build the Great Wall, to be precise, it continued to build, because as early as the Yan Kingdom, the Zhao State began to build the Great Wall, and Qin Shi Huang only connected what they built. Qin Shi Huang built the Great Wall to resist foreign aggression, why did some people say that they harmed Europe?
Why did it take a lot of manpower and financial resources to build the Great Wall in ancient times? Qin Shi Huang was an emperor with a brain, certainly not for fun. In fact, at that time, the main purpose of Qin Shi Huang's construction of the Great Wall was to resist the northern nomadic Xiongnu, the Xiongnu as a nomadic people, although it caused any substantial danger to the Qin Dynasty, but the Xiongnu were a people living on horseback, all the raw materials for life were missing, except for meat, which day there was no grain to attack the surrounding areas. When the Qin Dynasty was ready to gather a large army, they had already robbed and rode away, for which Qin Shi Huang was also very distressed, after Qin Shi Huang unified the Six Kingdoms, the land area increased a lot, and the military jurisdiction was not perfect, so the surrounding areas were always invaded by foreign countries. Although the Xiongnu did not dare to make a big move, Qin Shi Huang did not know where to focus on defense.
Why not build a Great Wall in the north? This would allow them to be held out outside the Great Wall, and when they did not have horses to attack the city, their combat effectiveness would be vulnerable. And every other distance to build a beacon tower, when the Xiongnu came to invade, they lit the beacon, when other places saw that there was a beacon, they could gather troops to support, so the Qin Dynasty used a lot of manpower and financial resources to start building the Great Wall, such an idea is good, but when it is really built, it is very troublesome, because it takes a lot of manpower, material resources, and financial resources.
The Huns were a nomadic people who did not farm, lived by herding, and they lacked food every winter. Now that the Qin Dynasty has built the Great Wall, there is no hope of encroachment. But they had to survive, so they turned the spearhead and changed the target of the invasion from the Qin Dynasty to the European countries, which suffered under the powerful iron horse of the Xiongnu. In the early days, the Great Wall shifted the flames of war from the Qin Dynasty to Europe, and in the later period it blocked the exchange between China and the West, which was not conducive to the visit of Europe to China in the later period. This is also the pros and cons of building the Great Wall.
Because the barrier of the Great Wall also interrupted the trade between China and the West, from the Qin Dynasty onwards, the world outside the Great Wall was a hostile attitude, even after the pacification of the Xiongnu, this deep-rooted concept could not be removed in people's minds. The Great Wall is like a gate, and only by closing the gate will you feel safe. Before Zhang Qian of the Han Dynasty sent his mission to the Western Regions, the West had always had an unknown attitude towards the Han Dynasty, and when the Silk Road connected the economies of China and the West and brought the advanced technology of the Han Dynasty to the West, people really understood this ancient Eastern power, and the Western science and technology achieved new developments and breakthroughs in some unknown fields.
The Great Wall is an ancient chinese building, and the emperors of all dynasties and generations are very concerned about the Great Wall and strengthen the construction of the Great Wall, because this can not only effectively prevent foreign aggression, but also this is a precious treasure left by the ancestors.
