Zhao Gao
When Qin Shi Huang died while away from the capital, Li Si and the chief eunuch Zhao Gao suppressed the late emperor's choice of successor, which was Fusu. At that time Fusu was close friends with Meng Tian. If Fusu became the next emperor there was a high chance Meng Tian would replace Li Si as prime minister. Fearing a loss of power, Li Si decided to betray the dead Qin Shi Huang. Li Si and Zhao Gao tricked Fusu into committing suicide, and installed another prince, Qin Er Shi (229 BC – 207 BC), in his place. During the tumultuous aftermath, Zhao Gao convinced the new emperor to install his followers in official positions. When his power base was secure enough, Zhao Gao betrayed Li Si and charged him with treason. Qin Er Shi, who viewed Zhao Gao as his teacher, did not question his decision. Zhao Gao had Li Si tortured until he admitted the crime and once even intercepted a letter of pleas he had sent to the Emperor. In 208 BC, Zhao Gao had Li Si subjected to the Five Punishments and executed via waist chop () at a public market and also had his entire family to the third degree exterminated. Sima Qian records Li Si's last words to his son as having been, "I wish that you and I could take our brown dog and go out through the eastern gate of Shang Cai to chase the crafty hare. But how could we do that!"
