Zhao Gao. Zhao Gao's ancestral home is from the State of Zhao. He grew up with his mother in the palace of Qin since he was a child, and he has been purified since he was a child. Zhao Gao was a strong and capable man and was proficient in calligraphy. He was promoted and appointed by Qin Shihuang. He later tutored Qin Shihuang's youngest son Hu Hai. In 210 BC, Qin Shihuang began his fifth tour and died of illness in the sand dunes. At this time, Zhao Gao began to plan a coup. He said After consulting Prime Minister Li Si, he tampered with the imperial edict and established Hu Hai as emperor, and issued an imperial edict to kill the young masters Fusu and Meng Tian. In fact, Hu Hai did not want Meng Tian to die, but Zhao Gao had committed crimes before and wanted to ask Meng Tian's younger brother Meng Yi not to report. But because Meng Yi was rejected by him for his integrity, Zhao Gao held a grudge. In the end, Zhao Gao ordered Meng Yi to hang himself. After Zhao Gao won the coup, he did not stop killing people. He used Li Si's son Li You to kill Li You on the groundless charge of foreign enemies. After killing Li Si's family, Li Si was cut in half. He then became the first eunuch and prime minister in Chinese history. Then uprising armies rose up in various places. He was afraid that the Second Emperor would find out about the situation outside and blame him, so he sent his son-in-law Yan Le to lead troops into the palace. He killed the second generation and established Ziying as emperor. He originally wanted to use it to continue to control the state affairs of Qin, but Ziying killed him first in the Qin palace. Zhao Gao kept harming people throughout his life before he achieved his goal. It can be said that the reason why the Qin Empire perished so quickly had a lot to do with him. Even so, he could not escape the punishment of God. He followed the old saying, harming people. It will end up harming yourself!
