For the word eunuch, people's first impression is that there is a defect in a certain part of the body, and then it is a sharp voice, which is extra infiltrative, and because of the operation, their psychology is not particularly healthy. But in fact, the word was originally a title for higher-ranking officials, and it was not until the Ming Dynasty that eunuchs were called eunuchs, and then it became a special pronoun. In this way, there is no eunuch who must be a physically defective person. For example, Zhao Gao, people generally think that he is a eunuch, but in fact, he is not really a eunuch.

He was a royal nobleman and held important positions, but after the death of Qin Shi Huang, he feared that his position was threatened, so he found Li Si and conspired with him to forge the emperor's edict, causing Fu Su to commit suicide, and then supporting Hu Hai to ascend to the throne. Because Hu Hai could do nothing, and after succeeding to the throne, he began to indulge in wine, which made Zhao Gao more indulgent, monopolizing power in the court and exercising the power of the emperor. Later, not satisfied with this, he killed Hu Hai and made Zi Bao the king, and Zi Bao knew that he was just his puppet, so he designed to kill Zhao Gao, and even more so, Zhao Gao ended his sinful life.
The reason why he so much harmed the Qin Dynasty was because he particularly hated the Qin Dynasty, because he was originally a nobleman of the Zhao Kingdom, but at that time, both the king and the heirs of the nobles were generally sent abroad as hostages, and it was actually difficult to go back in the end. He stayed in the Qin State, and his status was even lower than that of the ordinary people in the Qin State, so you can imagine his treatment. Therefore, he started from the official field, first allowing himself to read military books and then practicing a good martial art. Later, at the age of fifty-one, he became the prime minister and took power. Therefore, he began to sabotage the Qin Dynasty, causing a sharp decline in national strength and the imperial court.
The reason why later generations said that he was a eunuch was, on the one hand, because the literati of later generations hated him very much, and he caused chaos in the government, murdered many important imperial courtiers, and caused the Qin Dynasty to collapse rapidly, so they scandalized him as a eunuch. On the other hand, even in the Chronicle of History, it is not said that he was a eunuch. However, people have some misunderstandings about its records, and in the biography of Meng Tian in the historical records, it is written that Zhao Gaoyin Palace, but in fact, this is a misunderstanding, and the correct should be the hidden official. A hermit is a workplace where someone with a disability is housed. His mother was tortured because of her guilt, so she worked as a hermit official, and later Zhao Gao and his brothers were born here, so they were not eunuchs at all.
In addition, Zhao Gao was not only not a eunuch, but also had a daughter, who later married Yan Le, who participated in the coup and led troops to kill Qin II.
