At the end of Living Hell, the characters in Li Boyuan's book borrowing said that the prison system in China in feudal autocratic society was really dark to the extreme! Undoubtedly, the unjust prison created by feudal rulers, the cruelty of cruel officials and the cruelty of prison owners are closely related to autocratic rule. Even the lynching and humiliation of prison leaders are the evil consequences of the essence of the old prison. Simple prison cells and inhuman prohibited tools provide objective conditions for their misery; The purpose of prohibiting simple punishment in prisons has cultivated their cruel nature; Corrupt officials' bribery led them to blackmail prisoners under their control. As Hugo, a great French writer, said, these people are "the embodiment of prison" and "the embodiment of prison" ... just like the image of a bolt, they have the image of a person. This wall is a prison of stones; This door is a wooden prison; And these warders and guards are prisons with bones and muscles. Prison is a terrible, complete and inseparable thing, half a house and half a person. Moreover, in a sense, the living torture devices of the warden and the prison bully are more fierce and terrible than the death penalty in prison. If the living things are immoral, it is unthinkable to do bad things.
