There were many complicated and strange cases that happened in ancient China. Not only were the plots of these strange cases thrilling and complicated, but the process of solving the cases was also difficult and tortuous, and full of suspense.
These strange cases not only have strange plots and difficult and tortuous solving processes, but also often strongly reflect the conflict between good and evil, good and evil, loyalty and traitor, which is touching and thought-provoking. Therefore, literati in the past dynasties either recorded them in the annals of history, or wrote novels, notes, operas and other literary and artistic works based on them, while the general public regarded them as topics after dinner. Shocking anecdotes were widely circulated and have survived for hundreds of years.
