Zhao Gao refers to a deer as a horse.

1. Although Zhao Gao was a eunuch, he was a controversial figure in history, including his life experience, birth year, merits and demerits. This man is proficient in law. Although he was a eunuch, he was deeply loved by Qin Shihuang. However, he is also an evil figure who can reverse good and evil, right and wrong, loyalty and treachery, beauty and ugliness. It can be said that Qin died in his hands.

2. At that time, Hu Hai and Qin Ershi were young and ignorant, and they always depended on Zhao Gao. They were ignorant of Zhao Gao's ambition. Zhao Gao has always been listed as a junior after Reese, while Qin Ershi doesn't think that Zhao Gao has any plans to go into politics.

One day in August in the third year of Qin Ershi (207 BC), Zhao Gaoyou had a deer brought up and said to Qin Ershi, "Your Majesty, I will give you a good horse." When Qin Ershi saw where it was, it was obviously a deer. He smiled and said, "The Prime Minister is wrong. This is a deer. How can you say it's a horse? " Zhao Gao said with a smile, "Please look carefully. This is obviously a swift horse. " Qin Ershi looked at the deer again and said incredulously, "Why does a horse have horns on its head?" Zhao Gao said, "If you don't believe me, you can ask all the ministers."

Ministers know that he has run amok, reversed right and wrong, and dared to speak out. Some honest ministers insisted that it was a deer, not a horse, and some Zhao Gao confidants listened to Zhao Gao. Before long, those honest ministers were punished by Zhao Gao in various names and even hacked to death.

5. The storm of "referring to a deer as a horse" let Zhao Gao know who depends on himself and who opposes himself. The next day, Zhao Gao sent a fortune teller to see Hu Hai and said, "Your Majesty, you can't even tell a deer from a horse. It must be that you didn't fast well when you sacrificed, and your head was dizzy. " Hu Hai didn't doubt him, so he went to Shanglinyuan to fast. Later, Qin Ershi accidentally shot a passerby during a hunting. Zhao Gao said to Hu Hai through Hu Hai's shooting of the living: "Your Majesty, if you kill someone for no reason, God may blame you, so you should hide." Hu Hai immediately hid in Wang Yigong outside Xianyang. Zhao Gao's cronies were in Wang Yigong, but Hu Hai, who had been trapped in a cage, didn't know it and lost his life in a daze.

6. After Hu Hai's death, Zhao Gao wanted to be king by virtue of his bloodline of winning the surname Zhao. But because he was a eunuch, he had to pass the imperial seal to Zhao Ziying, the younger brother of Qin Shihuang. Because the strength of Qin was not as good as before, Zi Ying had to cancel the title of emperor and call it the King of Qin again. Then he negotiated with his personal eunuch, Han, and agreed to cut off Zhao Gao's plan, so that Zhao would be superior to the public and the three clans would perish.
