Qin Shihuang contributed a lot, and his contribution must be greater than in the past. The most important historical achievement of Qin Shihuang was to complete the great cause of reunification and establish the first feudal centralized state in history. Qin Shihuang's contribution also lies in laying the foundation of a multi-ethnic feudal country. Some policies and measures implemented after Qin's reunification not only affected the feudal society in the next two thousand years, but also affected the present, such as the unification of characters. He is not only a politician with great contributions, but also a tyrant. It's true that punishing people is cruel, but history is often like this. Because of the rapid development, it will leave future troubles. Because drastic reforms will gain and lose, there are many opponents. Without the pain of Qin reunification, there would be no peace after the civil strife, and how many people would be killed or injured?
Emperor Wu of the Han Dynasty is an emperor with outstanding contributions. The Western Han Empire in the Hanwu period was the most powerful country in the world at that time, and it was also a relatively strong period in the history of China. There has been a saying that "the Han and Tang Dynasties flourished". The "Han" here mainly refers to the period of Emperor Wu of the Han Dynasty. People often compare Emperor Wu of the Han Dynasty with Qin Shihuang, because China's feudal autocratic centralized state was established by Qin Shihuang and consolidated by Emperor Wu of the Han Dynasty. During his 54 years in office, he implemented many new measures, which brought unprecedented prosperity to the Western Han Dynasty.
