Zibo Kunlun Prison's sentence has expired.

You don't need to go through any formalities to get out of prison. Just fill out a form and issue a release certificate, which is usually sent directly to the released person.

If you want to know the exact release time, you usually have to contact your family actively, such as whether you get commutation or parole, the exact release time and so on. These are all known by your relatives on their own initiative, and the prison will not take the initiative to inform your family. Prisoners do not need to hand in materials after serving their sentences. Generally, the prison office staff fill in the prisoner's exit appraisal form, truthfully fill in the basic performance and rewards and punishments of the prison reform, and conduct appraisal through the prison meeting. After the expiration, the prison management department will review and handle the release certificate.
