My friend is being held in Jimo Pudong Detention Center. I want to ask.

Hello, first of all, your friend was sentenced not because he didn't testify in court, but because he was really involved in the crime, or because he didn't appear in court to defend himself. Those who shelter others are generally sentenced to fixed-term imprisonment of not more than three years, public surveillance or criminal detention, and are also fined. Of course, this is without involving other crimes. Before the court decides, the family members need to entrust a lawyer to meet, and after the judgment, the family members can apply for a meeting.
