Why did the Qin Dynasty perish so soon?

The whole world says that Qin died of tyranny, as the saying goes, the king of Qin has no way, and the world is against him. This childe quite disagree. First, the burning of books to cultivate Confucianism in the Qin Dynasty is nothing compared with the ousting of a hundred schools of Confucianism by Emperor Wu of the Han Dynasty. Besides, burning a few books can ruin the country. It's a joke. Second, Qin Fei has no way. Qin is only known for its strict laws and strict sitting. It embodies the rule of law and the ruthless law. Qin's laws are harsh, but it is in this legal background that Qin Neng swept Liuhe and the whole world from a vassal of Xirong in the northwest, swallowing mountains and rivers. It is true that this law may not be acclimatized. In the homeland of the Six Kingdoms, the local people can't adapt to the laws and regulations with Qin characteristics. However, there was an invincible million-strong division in the Qin Dynasty. This army once made people feel frightened and turned pale. According to Sima Qian's Records of the Historian, Qin Jun went into battle shirtless, holding prisoners under his arms and carrying the enemy's head (this is related to the military reward system of the State of Qin, and the reward of the Qin army is based on the head, so the head is the most important), which is extremely brave. And Qin Jun's military experience was the highest at that time. The production process of Qin weapons is also the best, and the assembly line production procedure has been implemented. For this reason, Qin still uses bronze weapons instead of iron weapons (because the production process of bronze weapons was much more mature and perfect than iron weapons at that time). Imagine why such a powerful army fell apart in just a few years! ! Why was an army that could sweep the six countries wiped out by the newly armed peasant rebels? Why can an army in Changping fight with Zhao's 45, fighters for several months and be wiped out by the 3, cross-swords Xiang Army? In the end, this army couldn't even keep the pass (Hangu Pass) and lost its lair. Imagine that when Su Qin held the seal of six countries, he could not capture a million troops. Liu Bang and Xiang Yu both had only tens of thousands of troops, thus putting an end to the mighty Qin Dynasty. Why on earth is this? ! This childe secretly thought that it was the internal consumption of the Qin Dynasty that fulfilled Liu Bang's boy. Qin Shihuang's failure lies in his failure to establish his eldest son, Fu Su, as a prince (this is an eternal mystery) and improper use of personnel, especially his trust in Reese, a villain, and a sand dune conspiracy. Which led to the subsequent killing of General Fu Su and General Meng Tian. Jiangshan fell into the hands of this fellow Hu Hai. In a few years, eunuch Zhao Gao killed Hu Hai, made Zi Ying, the son of Fu Su, emperor, and then Zi Ying killed Zhao Gao. All this led to the internal division of the Qin Dynasty, which quickly lost its political and military advantages. What's more serious is that when the uprising started, 2, Qin Jun, who fought against the Huns in the north, and 3, Qin Jun, who was in Baiyue (now Vietnam), stayed put. Isn't it strange? Even in the end, the Qin dynasty relied on prisoners to guard the capital Xianyang. Now the truth of history is clear. Qin Fei died in tyranny, nor in the resistance of the adherents of the six countries to Qin, but in his own backyard. 15 years, it took only 15 years (221 ~ ~ ~ 26 BC) from the most powerful to the extinction, which is worth pondering! ! ! !

Qin's downfall is rooted in two people, one is Reese and the other is Zhao Gao.

why do you say Reese? In The Theory of Qin Dynasty, it is said that it is because the law remains unchanged. After reading many books, I don't think it is. If it is said that the Qin law is too strict, why didn't the Qin people rebel and respond in a chaotic time? There is a lot of noise outside, except Guanzhong, which is not owned by Qin, but Guanzhong is quiet. Xiang Yu killed 2 thousand people in the pit, all of whom were Qin people. So, the reason is not the law, but because the Kanto people and the Qin people were not family at that time, that is to say, the Qin people were Qin people, and now they are Shaanxi people. If you just pull a province, such as Hebei people, you can't say that they are Qin people, but if you say that he is Han Chinese, he will certainly not object. Therefore, the anti-Qin cause at that time was so vigorous, and the most important reason was that when everyone didn't think they were Qin people, that is to say, there was no such orthodox idea in the mind of the Qin dynasty, and there would be the idea that although three families died, Qin would be Chu. We know that China people's orthodoxy is very heavy. Wang Mang usurped the Han Dynasty, and everyone helped him recover. The most important reason for this is that the Qin Dynasty did not implement the enfeoffment system. Everyone may know the disadvantages of the enfeoffment system, but it has its value because it existed. As mentioned in Ma's The Prince, when the kingdom conquers a region, there are two ways to occupy it permanently. One is to station a large number of troops, which is useful, but not economical. Second, the monarch lives directly in the newly occupied place. But there is only one monarch. The enfeoffment system actually played the role of the monarch body double. Many things are not harmful or beneficial to light, but the important thing is to weigh them. When the king of Qin took the examination rate, the victory was not as interested as some people thought, so he listened to Reese. So when Chen Sheng uprising, I said nothing but Xiang Yu and Liu Bang, who finally played a decisive role in the process of eliminating Qin, and Xiang Yu opposed it with the local satrap, and then killed the satrap himself unexpectedly; Liu bang discussed with the county magistrate to get along well, but later the county magistrate saw that Liu Bangren was afraid of not controlling his remorse before he could kill him. It can be seen that the local officials of Qin played a role. Who can say that the demise of Qin has nothing to do with the absence of packet?
