趙高
Li Si and the chief eunuch Zhao Gao conspired to kill Fusu because Fusu's favorite general was Meng Tian, whom they disliked and feared; Meng Tian's brother, a senior minister, had once punished Zhao Gao. They believed that if Fusu was enthroned, they would lose their power. Li Si and Zhao Gao forged a letter from Qin Shi Huang saying that both Fusu and General Meng must commit suicide. The plan worked, and the younger son Hu Hai became the Second Emperor, later known as Qin Er Shi or "Second Generation Qin".
