In October of the 12th year of Tongzhi in Qing Dynasty (AD 1873), a murder case occurred in Yuhang Town, the seat of Yuhang County, Zhejiang Province, and Ge Pinlian, a waiter of tofu shop, died of a sudden illness. The death of her son's nose and mouth bleeding aroused the suspicion of Ge Mu Shen Yushi, who believed that her son's death must be related to her daughter-in-law. Daughter-in-law Bi Xiugu is the first beauty in Yuhang Town. She is handsome and watery, and people call her "Chinese cabbage". Liu Xitong, the magistrate of a county, suspected that Yang Naiwu, the juren of this county, seduced Bi Xiugu, the wife of Ge Pinlian, and poisoned Ge Pinlian, and tortured Yang Naiwu and Bi Xiugu to extract confessions, and he was convicted of "seeking husbands and taking wives" and reported it to the Hangzhou government and the Zhejiang Provincial Department. Hangzhou government and Zhejiang province also broke up according to the original plan and reported it to the punishments. Later, Yang Shuying, the elder sister of Yang Naiwu, was charged by Beijing for the second time, which alarmed a group of justice officials in the court and appealed jointly. The imperial court decreed that the punishments should open the coffin for autopsy, and the truth was revealed and the unjust case was cleared.
