Beginning in 230 BC, Qin Shihuang wiped out the other six countries in a short period of nine years, and established the Daqin Empire, the first feudal monarchy in the history of China. During the reign of Qin Shihuang, the national weights and measures were unified, and the Great Wall of Wan Li was built to resist the invasion of Xiongnu. Take the achievements of Qin Shihuang Ying Zheng as an example. But unfortunately, such a perfect emperor died at the age of 49. It was because of his sudden death that the Qin Dynasty became a short-lived dynasty. So many readers think that if you give Qin Shihuang 30 years, you can create? Daqin Shi Sheng? Really? In fact, this is very possible. If Qin Shihuang can really live for 30 years, it is absolutely impossible for Qin Ershi and Hu Hai to ascend the throne of Daqin Empire and March in the direction of Qin Shihuang's budget. After the Qin Dynasty unified the six countries, Qin Shihuang gave his generals enough honor. For example, Meng Tian and others were sent by Qin Shihuang to the border town to protect the Great Wall, and Qin Shihuang sent his future heir Fu Su to Meng Tian, showing how broad-minded Qin Shihuang was. For veterans who can't fight, such as Wang Yi, Qin Shihuang also gave Wang Yi a lot of gold and silver jewelry, which solved the worries of veterans. This is the spirit of a generation of wise kings. Secondly, since Shang Yang's political reform, Qin Shihuang attached great importance to legalists, strictly enforced the rule of law, and severe punishment was essential, but it effectively ensured the fairness of the laws of the Qin Dynasty. ? Is the prince guilty of breaking the law with civilians? It is precisely because Qin respects the law from top to bottom that Daqin can make ten thousand people obey. On the surface, Qin Shihuang's collection of weapons from all over the world seems to be a restriction on the people. In fact, this restriction is also to protect the people. If we can reduce the number of civilian weapons, the people can reduce the bloodshed of many casualties. On the whole, Qin Shihuang was a brave and fearless emperor who could achieve great things. If he can live for 30 years, Zhao Gao and others should not covet the throne. If his son Fu Su succeeds to the throne, Qinchuan will have no problem for hundreds of years. Daqin became a short-lived dynasty because the sudden death of Qin Shihuang left a power vacuum. Moreover, Li Si, the prime minister at this time, colluded with Zhao Gao to make Hu Hai, the son of Qin Shihuang, emperor, which eventually led to the tragic ending of Qin Ershi's death.
