The hero of "Calling a Deer a Horse" is Zhao Gao. After Reese's death, Zhao Gao became prime minister. Regardless of the size, it was entirely up to him, and he almost became the emperor's father, and gradually ignored Hu Hai. One day, Zhao Gao took the opportunity of congratulations from his ministers and ordered someone to bring a deer to Hu Hai, saying, "I will present a horse for your majesty's appreciation." Although Hu Hai is confused, he can tell a deer from a horse. He laughed and said, "The Prime Minister is wrong. This is obviously a deer. How can you say it's a horse? "

Zhao Gao asked about ministers with a straight face; "Do you think this is a deer or a horse?" Some onlookers were awed by Zhao Gao's arrogance and remained silent; Some people are used to flattery and are busy saying that they are horses; Some people were puzzled by Zhao Gao's intentions and told the truth. As soon as II left, Zhao Gao executed those who dared to say "deer".

Brief introduction of other situations in Zhao Gao.

Zhao Gao started as a eunuch. During the reign of Qin Shihuang, he was promoted to the commander of CRRC Palace, Che Yu, and was asked to teach his youngest son, Hu Hai, to judge and break the prison. After the death of Qin Shihuang, Zhao Gao staged a coup in the sand dunes. He conspired with Reese to forge the imperial edict, forced Fu Su to commit suicide, made Hu Hai emperor and served as a doctor himself.

Relying on Hu Hai's favor, Zhao Gao monopolized power during his tenure, cronyism, heavier collection and stricter administration. In 208 BC, he designed and killed Li Si, and 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. Finally, Han Tan, the eunuch sent by Zi Ying, was assassinated, and all three families were killed.
