It is the long-cherished wish of several generations of monarchs in Qin State to unify the six countries, which was finally realized in the hands of the king of Qin. Immersed in the joy of victory, in order to show his success and highlight his supreme power position, at the beginning of the founding of the People's Republic of China, Qin immediately asked his ministers to discuss the issue of giving themselves titles. After discussion, the ministers and doctors of Qin thought that there were emperors, Huangdi, Tai Huang and Tai Huang in ancient times, and the most expensive was. Qin Wang's contribution to the unification of the six countries is unprecedented, which is beyond the reach of the five emperors. Therefore, everyone agrees that Tai Huang's honorific title is the most appropriate. However, the king of Qin did not fully adopt the opinions of ministers. He just adopted the word "emperor" and added the word "emperor", which is to give himself the title of emperor. Because this is the first emperor in the history of the Qin Dynasty, it is also called Qin Shihuang. The emergence of the title of emperor is by no means a simple change of the name of the emperor, but reflects the emergence of a new concept of governing the country, that is, the establishment of supreme imperial power. The tragic root of the centralized ruler lies in his violation of objective laws, and anyone who violates objective laws will not come to a good end. For example, the emperors of China are sincere in their pursuit of immortality and try their best to make an elixir. As a result, they lost their lives prematurely because he violated objective laws. For another example, Qin Shihuang wanted his family to be passed down from generation to generation, which violated the objective law. Under the dragon chair is a latent volcano. How can it be passed down from generation to generation? It's only a matter of time before it dies. Any efforts of centralized rulers are just stalling for time. There are only two tragic sources that cause great pain to human society: one is absolute power and the other is natural disaster. In today's world, human beings have awakened, absolute power can be eliminated and natural disasters are inevitable.
