Extended information:

There were two diligent emperors in the Ming Dynasty, one was Zhu Yuanzhang, and the other was Emperor Chongzhen Zhu Youjian. At the beginning of Emperor Chongzhen's accession to the throne, he purged the eunuch group headed by Wei Zhongxian, which brought some fresh air to the dark political arena at that time, and then used a large number of talents in the hope of changing the fate of the Ming Dynasty's demise. However, he later went on a killing spree, and the Ming Dynasty was in ruins. On his hand was destruction.

The Ming Dynasty was the last dynasty established by the Han people in China. Its establishment enabled the Han people in China to escape the brutal rule of the Mongolian aristocrats and once again win national independence; its demise made the Han people the object of slavery and oppression by the Manchu aristocrats, and China gradually fell behind on the world stage.
