Sun Haohui's " The Great Qin Empire " was a historical novel that made up the historical background and character settings of the Qin Kingdom. However, there were some differences between the history of Qin State depicted in the novel and the historical facts. Here are some historical issues that may be involved: 1. The name of Qin State was "Qin" and not "Great Qin Empire". The Qin State was founded in 246 B.C., not 221 B.C. The capital of Qin State was Xianyang, not Xi'an. Qin's monarchical system adopted an autocratic monarch rather than a constitutionalist one. After Qin unified the six states, it was Legalism that emphasized the rule of law and reform, rather than benevolence and etiquette that Confucianism emphasized. After unifying the six states, Qin carried out a series of reforms and constructions, including the construction of the Great Wall, the promotion of ironware, the unification of currency, and so on. These activities had a profound impact on Chinese history. Although " The Great Qin Empire " made up the history of Qin, it also reflected part of ancient Chinese history, which helped people better understand and understand ancient Chinese history.
