After criminal detention, people will always be held in detention centers, and their families will not see them. Only after a few months or more, when the case is heard in court, can their families see people.
After a person is detained in a detention center, his family can only entrust a lawyer to meet with him to understand the case and the needs of the detainee.
Criminal procedure law:
Article 33 A criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or compulsory measures are taken. During the investigation, only lawyers can be entrusted as defenders.
Article 37 A defense lawyer may meet and correspond with a criminal suspect or defendant in custody.
