Cause

Zhou Jia brought Mr. Qian and two clerks to the county office to check the files of the taxes and various cases in Ling County. When Mr. Qian flipped through a case file called Qi Shilian, he found that a man named Zhao Cheng had sued Qi Shilian of the Qi family's medical center for misdiagnosing and causing the death of his mother. Qi Shilian refused to admit it and was imprisoned. Before the case was investigated, Qi Shilian died in prison and the case was left unsettled.

There was also a dossier noting that after Qi Shilian died in prison, his son, Qi Zhanpeng, sued Zhao Cheng for false accusation. In the end, for some reason, the case was left unsettled and the two cases were not closed.

Mr. Qian felt a little suspicious and brought the dossier to Zhou Jia. "Sir, look, these two cases involved the same person, but both cases are not closed. I remember that the young man who wrote for a living today was also called Qi Zhanpeng. Could it be the same person?"
