After the establishment of the glorious Qin empire, Qin Shihuang once thought smugly: I am the first emperor, and there are many descendants, and the second and third generations will last forever. However, the Qin dynasty did not go through the third world, but enjoyed the country for fifteen years, so the country changed its name and died. There are many reasons for this. Zhao Gao's role is not the fundamental reason, but it is also an important reason. People in the Han Dynasty said: Qin let Zhao Gao control his car. People in the Qing Dynasty said that # 2 was the first to destroy the imperial clan, and Zhao Gao was rival.
