After discovering that some migrant workers fled back to Pei County, the county magistrate knew that Liu Bang had run away. In order to find Liu Bang's whereabouts, the county magistrate could only arrest Liu Bang's wife in Pei County, but since Liu Bang had never been back to Pei County, his wife did not know. In addition, the laws of Qin were very humanized at that time, and the human rights law had begun to take shape. It is also prohibited to extract confessions by torture. However, the county magistrate in Peixian mainly acted according to law, rather than extorting a confession by torture in order to get the news of Liu Bang. This is practical and conscientious.
People who know the history of the Qin Dynasty should know that there is a special part in the laws of the Qin Dynasty to write the criminal procedure law, mainly focusing on the laws and regulations to protect the human rights of criminal suspects. This law stipulates that the prisoner's account must be heard and recorded during the trial, and no interruption or reprimand is allowed in the process. Even if you feel that there is a flaw after listening to it, you should listen to its excuse and record it. But if you are too tired to justify yourself, you will be punished. Therefore, for Liu Bang's wife, if she doesn't lie and tells everything she knows during the interrogation, the county magistrate can't torture her.
In fact, all the laws of the Qin Dynasty were formulated by Qin Shihuang and implemented from top to bottom. As a result, Lv Hou was not embarrassed, tortured, beheaded or imprisoned for a long time, but was put back home after a few days.
