That was after the death of Song Zhenzong's first queen. At that time, Liu Fei and Li Fei were pregnant. Obviously, whoever gives birth to a son may be the main palace. Liu Fei had been jealous for a long time, fearing that Li Fei would be made queen after giving birth to his son, so he made suggestions with the palace master Guo Huai. With the cooperation of the midwife You Shi, he took advantage of Li Fei's delirious dystocia to peel off the fur of a civet cat and replace it with a newborn prince with blood and oil. Liu Fei ordered the maid-in-waiting to knock on the beads and strangle the prince. Kou Zhun couldn't bear it, and secretly handed the prince to eunuch Chen Lin. Chen Lin put the prince in a suitcase and sent him to Nanqing Palace to raise him. In addition, when Zhenzong saw the skinned civet cat, he thought that Li Fei had given birth to a monster and exiled it to the cold palace. Soon, Liu Fei gave birth, gave birth to a son, and was made a prince, and Liu Fei was also made a queen. Who knows that six years later, the son of Queen Liu died. When Liu Houxing learned that Li Feisheng's son was not dead, he took him in and raised him to fill the vacancy of the prince. One day, the prince met his birth mother Li Fei in the cold palace. Both of them were born with tears on their faces. When Liu learned this, he tortured Kou Zhun, and Kou Zhun touched the steps and died. Then, Liu slandered in front of Zhenzong, and Zhenzong ordered Li Fei to be executed. The little eunuch Yuzhong was willing to be martyred for Li Fei and let her go. Another eunuch, Qin Feng, took Li Fei out and sent him to Chen Zhou. Qin Feng also set himself on fire. Li Fei couldn't live in Chen Zhou, but he ended up living in a broken kiln, begging for food. Fortunately, Bao Zheng released grain in Chen Zhou, learned the truth, took in Li Fei and her son, and brought Li Fei back to Kaifeng. At this point, the true Sect has perished, and Li Fei's son became emperor, known as Song Renzong in history. Bao Zheng also used the opportunity of entering the palace to congratulate Queen Injong on her birthday to bring Li Fei into the palace, so that Li Feicai could meet his own son Injong and tell the truth.
Later, Bao Gong designed Chen Lin to tell the truth. Liu, who was the queen mother, knew that the plot was exposed and died of convulsions. Bao Zheng was appointed Prime Minister by Injong because of his great contribution in this case. The whole story is vivid and tortuous, with a beginning and an end, so someone made it into a drama and put it on the stage, which caused great influence in society. The story of the civet cat becoming a prince is because Renzong did recognize his mother in history.
