Zhu Yuanzhang, the pioneer of the Ming Dynasty, was ruthless and killed people without blinking an eye, but he deeply understood the harm of eunuch chaos. In order to keep Zhu Jiachao standing, he specially hung a plaque on the door of the palace, which read the words that ministers should not interfere in state affairs and those who disobey orders should be beheaded to warn future emperors that it is forbidden to appoint eunuchs to handle affairs.

However, Zhu Yuanzhang's mediocre grandparents and grandchildren could not take his words seriously at all, which led to endless troubles for the eunuchs in the Ming Dynasty and seriously shook the rule of the dynasty. The disaster of castration was comparable to that of the Eastern Han Dynasty and the Tang Dynasty. After Ming Yingzong Zhu Qizhen came to power, he relied heavily on Wang Zhen, the eunuch who raised him. When his mother Zhang and Sanyang were alive, they didn't dare to make waves, but after Zhang's death, Sanyang died, so naturally they couldn't resist. Arrogantly, he took the iron plaque made by Mao outside the palace gate and intervened in politics generously. Courtiers who dare to be rude to him and those who dare to speak ill of him will be put in prison or brutally executed. Ming Yingzong ignored the opposition of courtiers, only listened to Wang Zhen, and was captured by Walla Army.

Amin Wuzong Zhu Houzhao, stubborn by nature, is also a favorite of eunuchs. His name is Liu Jin. Liu Jin specially arranged a leopard room for him to collect beautiful women and wild animals from all over the country for him to play. Liu Jin took this opportunity to monopolize the power and bring disaster to the country and the people. The courtiers secretly called him Emperor Liu. The East Factory, the West Factory and the Royal Guards are all controlled by eunuchs, and they all obey the arrangement of Liu Jin. After the fall of Liu Jin, the emperor was shocked to find imperial robes, jade belts and other special items from his home.

Emperor Amin, Zhu Youxiao, loved carpentry all his life and did nothing. He handed over state affairs to his wet nurse, Hakka, and eunuch Wei Zhongxian. Wei Zhongxian, who claimed to be nine years old, was in power, mastered the actual state affairs, formed the eunuch power, and created many false and wrong cases of Lindong Party, which directly brought the Ming Dynasty into the abyss of perdition. Zhu Yuanzhang under the grave would never have thought that he had so many unworthy descendants.
