This rumor should be false. In the Qing Dynasty, the number of newly built Great Wall was very small, and the old Great Wall was only repaired for a long time. As early as the Western Zhou Dynasty, the northern part of the Great Wall began to be built. At that time, the Great Wall was built to resist the nomadic people in the north, so it has been built slowly since then. Later, in the Spring and Autumn Period, various vassal states were slowly building the Great Wall, not only in the north, but also in the south.
After continuous construction in various dynasties, by the time of the Qin Dynasty, few Great Walls needed to be built, and most of the time was spent on repairing the old Great Wall. The Great Wall of China that we are talking about now is not the original Great Wall, but the result of continuous repair from generation to generation. After the Ming dynasty, it was enough to have it, and it was renovated once to make the Great Wall stronger. The work of repairing the Great Wall was still being done in the Qing Dynasty. The Great Wall that we see when we go to Beijing now is actually mostly repaired by the Ming and Qing Dynasties. It didn't take long for the Qin Dynasty to build the Great Wall, which didn't add up to more than ten years. In such a short time, it is impossible to spend a lot of manpower and material resources.
Besides, other major projects were still under construction in the Qin Dynasty. According to historical records, more than 7, laborers were mobilized when the Epang Palace was repaired, and some walls that blocked countries needed to be removed, which also required a lot of manpower. Many projects are under construction, so there is not much labor to build the Great Wall. Generally, the labor force in ancient transportation was mostly young and middle-aged, while the old people and children had no strength and could do nothing, so they would just stay at home. At that time, there were not so many young people, and the number was limited. In the distribution of the number of people in various major projects, reasonable plans will be made, and most of the manpower will not be concentrated on repairing the Great Wall, because other projects are also very important.
besides, repairing the Great Wall is not a war with troops, and there is no sword and shadow, and we will meet each other at short notice. At most, they can only die because of illness or overwork. The mortality rate is definitely not war, and the mortality rate is high. From all angles, at that time, the number of people who built the Great Wall by Qin Shihuang was very small, and many people who died were rumored to be false.
