First, according to historical records, Yong Zhengdi was killed by a woman who came for revenge, and her head was cut off. This woman flew away with Yong Zhengdi's head.
This was also an unsolved case at that time. After all, it was the emperor who killed it. Still attracted a lot of people's attention. At that time, such a woman should be punished by Jiuzu, but according to historical records, this woman's whole family was killed by Yongzheng, so she wanted revenge.
Second, there is not much practical basis for this statement.
After all, it is based on historical records, and the truth remains to be verified. But there is indeed such a legend in history, which has been passed down from generation to generation and has been passed down to this day. So Yong Zhengdi didn't die of illness or karoshi, but was killed by a woman who came for revenge. That's why he was called the most cowardly emperor in the Qing Dynasty.
To sum up, the most cowardly emperor who died in Qing Dynasty was Yong Zhengdi. He was killed by a woman, and his head was taken away by this woman, and he didn't find it when he flew away, so he was not a complete body when he was buried. So he was called the most cowardly emperor in Qing Dynasty. There are many versions about the cause of Yong Zhengdi's death, but most of them were killed by a woman and her head was taken away, so the credibility of this matter should still be quite high.
