Let's talk about the first point. When he became emperor, Zhu Houzhao could not choose a candidate. As an emperor, he should choose people wisely, while Zhu Houzhao attached great importance to eunuchs, which made Manchu officials dissatisfied and caused people's suffering. The eunuchs he used in western Zhejiang, relying on their own power, have always been very arrogant and lawless. Oppressing the people, occupying fertile land and doing evil. It made the people miserable and led to the intensification of internal contradictions in the Ming Dynasty, which was all caused by Zhu Houzhao conniving at eunuchs.
Let's talk about the second point. Zhu Houzhao is a person who loves beauty very much. For the woman you like, regardless of whether you are married or not, you will try your luck first. He visited the south of the Yangtze River, and without taking his own concubine, he asked eunuchs to find local women to serve him. Some people don't want their daughters to go, so eunuchs just grab them, even pregnant women are no exception.
Finally, the third point. It is understandable that Zhu Houzhao can fight, and his record in history is good, but he has no foresight. He once personally led an army and defeated the Mongolian army with fewer people. This is a true record in the history books, but he has no foresight. At that time, he thought Jiayuguan was not important, so he easily threw it away, giving the Tubo people the opportunity to occupy the territory near the Great Wall. So from these aspects, Zhu Houzhao is undoubtedly a bad king.
