Civet cats for princes, the classic story in the classic "Three Heroes and Five Righteousness", comes from the first, fifteenth, sixteenth, seventeenth, eighteenth and nineteenth chapters of "Three Heroes and Five Righteousness". Someone told Song Zhenzong Zhao Hengshi that Liu Fei conspired with Guo Huai, an internal reference, to exchange a skinned civet cat for a baby born in Li Chenfei, and Li Chenfei was put in limbo. After Zhao Heng's death, Renzong Zhao Zhen acceded to the throne, Bao Zheng investigated and dealt with Li Fei, the victim of Zhou Chen's uncle Pang Yu's fraudulent donation for disaster relief, and Bao Zheng accepted Li Fei's injustice to rehabilitate him and welcome Li to fly back to the DPRK. This story is well known to future generations.
