1. Warning function for criminals: Criminals commit crimes again in prison, which means that they don't have a deep understanding of their mistakes, which violates social morality and legal bottom line and should be severely punished by law. The result of the trial will not only serve as a warning to the criminals themselves, but also serve as a strong warning to other criminals, reminding them to seriously think about their actions and abide by laws and regulations.
2. The supervisory role of prison management: criminals commit crimes again in prison, which shows that prison management is flawed and fails to effectively control criminals and effectively reform and educate criminals. We must supervise and correct the deficiencies in prison management in order to improve the level and quality of prison management.
3. Warning function to society: Criminals committing crimes again in prison will bring serious harm and negative impact to society. Such criminals must be severely punished according to law, and at the same time, warning information should be sent to the society through trials to remind the public to strengthen supervision and management of criminals and safeguard the rule of law and security of society.
