During his tenure, he monopolized power, used power for personal gain, taxed more, and his administration was more harsh. In 208 BC, he designed and killed Li Si, and then he became the prime minister of the Qin Dynasty. In the third year, he forced Qin Ershi to commit suicide and made Zi Ying king of Qin. It was soon designed and killed by Zi Ying, killing three tribes.

Zhao Gao was born in the state of Zhao, and he is a descendant of the nobles of Zhao. It can be said that he lived a carefree life, but it didn't last long. In 228 BC, in the war to unify the six countries, the general of Qin took the lead in attacking Zhao, and Zhao Gao's father left Xianyang with Zhao Gao's four brothers to join Zhao. Zhao was defeated in the battle of Changping, and all of Zhao's 400,000 troops were buried alive, including these five fathers and sons.
From then on, Zhao Gao became a child without a father. After Zhao was defeated, his father and brother were both killed. Those who were not killed, including women and children, were taken to the state of Qin as slaves, including Zhao Gao, who was weak, and his mother. From then on, the three of them lived alone.
In the painful life, Zhao Gao's mother became ill again. Not only does she have no money to see a doctor, but she also has to drag her sick body to do rough work to earn money. Shortly after his mother's death, Zhao Gao held his younger brother in his arms and wept bitterly, vowing to subvert the State of Qin and avenge his relatives and tens of thousands of Zhao people in Qian Qian.
With hatred, Zhao Gao has never forgotten his mission of revenge. Finally, he stayed in Qin Ershi for three years, which helped Liu Bang and Xiang Yu to end their lives, and directly led to the downfall of the Qin Dynasty in troubled times. Although the folklore is not credible, it at least shows that Zhao Gao is not only a villain in many people's eyes, but also a loyal minister of Zhao.
