You know, before the Ming Dynasty, the demise of many dynasties was often due to their own reasons, such as ministerial power and political corruption. Therefore, after the establishment of the Ming Dynasty, Ming Taizu should avoid things similar to the Ming Dynasty, and he needed to control the power in the hands of ministers. So Ming Taizu chose to transfer the power of the minister to the eunuchs around him.
Of course, the eunuch's excessive power will also affect the imperial power, such as what happened at the end of the Han Dynasty? The chaos of ten regular servants? But in contrast, Ming Taizu thinks this is much better than giving ministers power. For example, although this eunuch has too much power, it will affect the throne. After his death, power will naturally return to the king. Instead of those ministers who are in power, they will pass on power to future generations.
Of course, there are times when eunuchs are allowed to do something shameful for themselves. For example, Emperor Judy of the Ming Dynasty sent Zheng He to the Western Seas. While enhancing the national prestige, he also sent Zheng He overseas to look for his missing nephew Zhu Yunwen. Because Zheng He is a close relative of Judy, he doesn't have to worry about others when he comes to do things for himself.
Of course, there were eunuchs who eventually became kings because they were young and helpless, such as Ming Yingzong, and Ming Yingzong was nine when he became king. At that time, when the imperial power was in the hands of the Empress Dowager and some powerful ministers, these people simply ignored the young Ming Yingzong. This naturally makes Ming Yingzong very uncomfortable. At this time, the eunuch Wang Zhen appeared, and he was closely related to Ming Yingzong. After that, he was deeply trusted by Ming Yingzong, which finally caused the difficulty of Jingkang.
