Vocational and technical education for criminals is an important part of China's education and reform of criminals. It is of great practical significance for prisons to carry out vocational and technical education for criminals. It is conducive to carrying forward the concept of "people-oriented", embodying the deep rational value of punishment, improving the basic vocational skills of criminals after they are released from prison, promoting their smooth transformation from "prison people" to "social people", becoming law-abiding citizens and self-reliant workers, thus ultimately preventing and reducing recidivism and promoting the stable and harmonious development of the whole society.
