As Cao Pi's favorite woman, why does her hair cover her face and her mouth is full of bran after her death?

Cao Pi's favorite woman is Guo Nvwang, a famous woman in history. The reason why she was treated so tragically after her death was because the newly succeeded emperor Cao Cao held a grudge against her, because in Cao Cao's eyes, Guo Nvwang had killed his mother, and if there was no Guo Nvwang, her mother would not have been abused, which is indeed the case. At that time, Guo Nvwang blew many times in xelloss's ear in order to win the favor.

Therefore, Cao Cao's attitude towards his mother is in his eyes. Then before Xelloss died, he had no good way to change this situation. Now that you've become an emperor, it's natural to ask for an explanation for your mother. I believe that not only Cao Cao would do this, but he would still do it if someone else replaced Cao Cao.

Secondly, Zhen Ji died in a miserable situation, and her hair was long, so she didn't have the graceful posture of Zhen Xuan. So after Guo Nvwang's death, Cao Cao also wanted Guo Nvwang to taste the suffering of his mother, so he ordered his men to fill Guo Nvwang's mouth with bran, which can be said to be revenge in disguise!

But then again, all this in Guo Nvwang is self-inflicted. Imagine that if she was not jealous of Zhen Ji, but lived in peace with Zhen Ji, I believe that Cao Pi would not be so cruel to Zhen Ji, and then Cao Cao might have awe of Guo Nvwang after he ascended the throne, but all this is just a hypothesis. After all, this kind of infighting can be said to be the most common thing in ancient feudal dynasties.
