The system of "graded treatment" refers to the management mode that criminals are divided into different grades and treated differently. Its purpose is to embody the policy of differential treatment and give play to the guiding and encouraging role of management. Prisons can be managed separately and treated differently according to the performance of prisoners' reform. Specifically, it is divided into three levels: strict management, general management and slack management, and criminals with different risks are treated differently. Graded treatment is dynamic, and you can get promoted and preferential treatment after the reform; Otherwise, it will be downgraded and subject to stricter management. In addition, the Prison Law also provides a reward and punishment system for criminals and sets up incentives such as leaving prison to visit relatives. It can be said that China made full use of progressiveness in prison reform.
