What did a 75-year-old man do to make Kangxi afraid and ordered him to be executed that year?

Because at that time, Kangxi mainly dealt with Zhu Cihuan. So I found a very old man to replace Zhu Cihuan. This is mainly because many people are engaged in anti-Qing activities under the banner of Zhu Cihuan. However, in later investigations, it was found that these people often had nothing to do with Zhu Cihuan. So in order to put an end to such a thing, Kangxi chose to find someone to pretend to be Zhu Cihuan, and then killed this person. Because once this is done, it is impossible for anyone to engage in anti-Qing activities in the name of Zhu Cihuan.

This actually had a lot to do with the demise of the Ming Dynasty at that time, because after Li Zicheng entered Beijing, Chongzhen chose to commit suicide. But later, the Qing army defeated Li Zicheng and occupied the original site of the Ming Dynasty. In addition, at that time, the Qing dynasty implemented some policies of tonsure, which made many children of the Ming dynasty feel very dissatisfied. This is why they engage in anti-Qing activities under various flags. This also brought great hidden dangers to the rule of the Qing Dynasty.

Of course, in the whole process of the Qing dynasty, the anti-Qing movement was not completely eliminated. This is mainly because the rulers of the Qing dynasty despised the interests of the Han people very much during their reign. Some Han Chinese were very dissatisfied, so they chose to overthrow Manchu. The Ming Dynasty, as the last feudal dynasty established by the Han people in the history of China, naturally became the name these people used to resist. And this name has also achieved very good results.

Of course, we can also see that Kangxi was actually a very successful monarch, and under his rule, the Qing Dynasty also reached a peak level. But Kangxi also made many mistakes that monarchs would make, that is, he became very fatuous in his later years.
