Personally, I think Qin Shihuang Ying Zheng is the most successful person. Qin Shihuang was the first monarch to use the title of "Emperor" in the history of China, which had a far-reaching influence on the history of China and the world. The Qin Dynasty established a centralized political system, which was followed by successive dynasties. Among them, the "three public officials and nine ministers" in the Han Dynasty basically copied the Qin system. Qin Shihuang's order to unify and simplify Chinese characters is a summary of the development and evolution of ancient Chinese characters and a great reform of Chinese characters, which has played an important role in the development of China culture. Qin Shihuang made many unprecedented achievements in unifying China, and listed several influential ones as follows: 1. Unify the written language, making it the foundation of a nation and continuing to this day; 2. Abandoning state-owned counties became the standard management mode after the unification of China, which lasted for thousands of years; 3. Unifying currency and weights and measures greatly facilitates domestic commercial exchanges. 4. Burning books to bury Confucianism, objectively unifying thoughts and avoiding the division of the country due to historical issues; However, the destruction of ancient books in various countries has made a considerable number of ancient cultural faults and ancient history in China dating, which is really regrettable; 5. The construction of Lingqu strengthens the control of the Pearl River Basin, making this area the territory of China forever; 6. Build the Great Wall to make it a natural dividing line between agricultural and nomadic peoples, and the Great Wall will become a national border for a long time; 7. Attack the Huns in the north and recapture the Hetao area, making this area the territory of China forever.
