What happened when civet cats became princes? When did it first happen?

In fact, this story is originally from China traditional opera, so it is difficult to judge whether the information in this story is true or not. However, the story he described was actually in the Song Dynasty, when concubines and spies conspired to exchange civet cats for real princes.

So Li Chenfei was in limbo because of this matter, so Bao Zheng later found this thing in the process of judging the case and rehabilitated her. In fact, from the beginning, what was put forward was mainly for the purpose of a theater, that is to say, I wanted to announce it to the world in a theater way. However, everyone is actually very confused about this matter, and I wonder if he has this matter.

In fact, civet cats are replaced by princes because there is such a thing in history. But because there is no clear identification, it is still difficult to judge whether the content of the matter is like this until now. In fact, in the end, Song Renzong didn't know his mother, and he also had many questions about his life, so he had a follow-up story.

In fact, in this whole incident, Bao Zheng didn't have much to do with it, because when it happened, Bao Zheng was just a commoner in cloth and clothes, so I later learned that Bao Zheng didn't really go to Beijing when he became a court official. So it was a dramatic event that the emperor didn't find his own mother at that time.
