According to this observation, it should be said that Qin Shihuang was an outstanding historical figure who made great contributions to the historical development of China, and was also a brutal tyrant. His achievements are the main aspects, but they can't cover up his sins; His sins are deep, but this should not erase his great historical achievements.
Qin Shihuang's most important historical achievement was to complete the great cause of reunification and establish the first feudal centralized state in history.
Of course, the unification of Qin is an inevitable trend of historical development, and the objective situation has created conditions for reunification. Qin Shihuang came to the orchard when the unified fruit was ripe. But this historical inevitability does not mean that the role of individuals is insignificant. Why was reunification achieved by the State of Qin? Why should reunification be completed in 22 1 year BC? In these respects, it shows the personal role of Qin Shihuang. But Qin Shihuang was still a rare tyrant. Qin Shihuang's cruelty can't be explained only by the general reason of "the nature of the landlord class". Tang Zhen once said: "Since Qin Dynasty, emperors have been thieves" ("Hidden Book Language"), and this view is correct. But the "thief" Qin Shihuang seems to be more tyrannical and guilty than other emperors. He is not only extravagant, but also causes the suffering of the broad masses of people; What is conducive to reunification is measures. Although it was beneficial to social development in the long run, it became a catastrophe at that time, such as the construction of the Great Wall. For decades, hundreds of thousands of people were recruited to do extremely heavy work. From the following records, we can see how terrible the pain caused by the burden of swinging labor is. Yang Tinglie, a A Qing writer, wrote in Fang County Records that a hairy "hairy man" was discovered. It is said that their ancestors were migrant workers who escaped the labor of Qin Shihuang to build the Great Wall. Because they hide in the deep mountains and forests, they are covered with long hair. It is said that when they met the long-haired man, he asked you first, "Is the Great Wall finished?" Is Qin Huang still there? He replied, "The Great Wall is not finished, and Qin Shihuang is still there! "Long-haired men will scare away. Of course, this record can only be regarded as a folk legend. However, if there is no such cruel reality in history, this terrible legend will never appear. It reflects that what Qin Shihuang did was based on the cruel exploitation and oppression of the broad masses of working people, which far exceeded the degree that society could bear, making it difficult to maintain the simple reproduction of society, so even some measures conducive to historical development caused disasters to the people at that time.
