If Qin was not destroyed by II, there would be no Han Dynasty, if the Western Han Dynasty was not destroyed, there would be no Eastern Han Dynasty, if the Eastern Han Dynasty was not destroyed, there would be no Three Kingdoms, if the Three Kingdoms were not destroyed, there would be no Jin Dynasty, if the Jin Dynasty was not destroyed, there would be no Sui Dynasty, if the Sui Dynasty was not destroyed, there would be no Tang Dynasty, if the Tang Dynasty was not destroyed, there would be no Song Dynasty, and if the Song Dynasty was not destroyed, there would be no Yuan Dynasty.
However, if any dynasty does not follow the historical routine, history will change, and the existing faces will no longer exist and be replaced by new faces. Therefore, any dynasty is the founder of the historical process of mankind. If you want to feel lucky to come to this world, you should thank the evolution of dynasties.
To sum up, without Qin Shihuang, there would be no later dynasties and modern society. Do you still want to scold Qin Shihuang?
