What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
As we all know, Qin Shi Huang was a very controversial emperor in Chinese history. Some people say that he was the greatest emperor of China, unifying the Six Kingdoms, unifying the script, and building the Great Wall. Some people also say that he is the most brutal emperor, burning books and pit Confucianism, building Afang Palace, regardless of the lives of the people of Li, and extravagant to the extreme. His merits cannot be matched, but his brutal character also caused the Qin Dynasty to perish in less than ten years. At the time of the fall of the Qin Dynasty, there was a Qin army of 500,000 people at that time, but not a single soldier resisted.

The Qin Dynasty because whether it was Qin Shi Huang or Qin II, they only cared about their own pleasures, regardless of whether the common people were dead or alive. Therefore, It led to Chen Sheng and Wu Guang standing up and revolting. So why was the Qin army, which could unify the Six Kingdoms, so vulnerable in the face of an armed uprising? This is because after the Qin Dynasty unified the Six Kingdoms, there were still some people of foreign nationalities who were not subdued, and these people had always been eyeing the Central Plains, so Qin Shi Huang had to arrange for the Qin army to go to the town to defend.
The factions were also the main force. Because the country was already unified and did not need too many troops, Qin Shi Huang sent 500,000 troops to border passes to guard the town. But these 500,000 troops did not go back for a lifetime, and until the end of the Qin Dynasty, these people did not go back, only because of a death order issued by Qin Shi Huang. That is, it is not allowed to go north.
After these people were sent to the border pass of South Vietnam, they actually completed the task of recovery very quickly, but Qin Shi Huang did not let them return. First, in order to ensure that it will always be under their own management, and second, they are afraid that the foreign people will continue to rebel, so they issued this order. However, the world is unpredictable, if there were these half a million troops in the first place, Chen Sheng, Wu Guang, and other non-governmental organizations would not be opponents at all. But in this case, the people may still have to live in the depths of the water.
