What kind of farce is the "civet cats for princes" in history? How did this farce end?

This is a palace fight farce, and it is a conspiracy for concubines to compete for favor.

Anyone who has seen Bao Qingtian Series knows the story of "Civet cats for princes". This story comes from the novel Three Heroes and Five Righteousnesses. It is about the Northern Song Dynasty. When the queen of Song Zhenzong died, she left no prince. So all the concubines in the harem have their own ideas. Whoever gives birth to a prince is the queen, even the queen mother.

Soon, Li Chenfei and Liu Fei became pregnant, but Mr. Li Chenfei gave birth to a boy. Seeing that things were not good, vlon colluded with eunuch Guo Huai, secretly replacing the baby with a skinned civet cat, claiming that Li Chenfei gave birth to a deformed child. At first glance, the emperor was very angry, so he put Li Chenfei in limbo, and then she fled among the people with the help of eunuchs. Li Chenfei gave birth to a child, and the maids and eunuchs sent by Liu Fei couldn't bear to kill him, so they gave the child to the Eight Immortals to raise.

Liu Fei soon gave birth to a prince and was made a prince. The good times didn't last long. The prince of Liu Fei is dead. Song Zhenzong had no children, so he had to adopt the descendants of the late king as a prince in Liu Fei. The child happened to be born to Li Chenfei, who was later Song Renzong.

Many years later, Li Chenfei, who was reduced to a folk life, happened to meet Bao Qingtian and told his identity and experience. Finally, under the investigation of Bao Qingtian, the truth that civet cats became princes came out, Li Chenfei was welcomed back to the palace by Injong, and Liu Fei, who had become the queen mother, committed suicide.

However, a novel is a novel after all. The historical truth is that Song Zhenzong loved the queen Liu E, but Liu E never gave birth. Later, Zhenzong favored Liu E's maid Li, who became pregnant and gave birth to a baby boy. Injong adopted the child to Liu E and Liu E for raising. This is the later Song Renzong Zhao Zhen.

Li was also named Chen Fei, but unfortunately, Li died on the same day. When she was buried, Liu E dressed her in the queen's clothes and gave her a first-class funeral.

After Liu E's death, Song Renzong came to power. He was told that his biological mother was not Liu E, but Li Chenfei, and Li Chenfei was poisoned by Liu E.. Song Renzong was very scared. He ordered Li Chenfei's grave to be opened, only to find that Li Chenfei was wearing the queen's clothes. He was very sad and honored. Song Renzong sighed. "You can't believe everything you say." He prefers the descendants of the Liu E family.

So the story is wonderful and we enjoy it, but we also need to know the historical truth.
