Write letters, articles, etc. Everyone needs to be checked, and they should be registered in detail, and then go through the formalities. The last step is to send the letter to the prisoner. If it is not inspected, it shall be handed over to the case-handling organ for handling.
Extended data:
To detain a criminal suspect in a detention center, one should rely on an arrest warrant, a criminal detention certificate issued by a public security organ or a state security organ at or above the county level, or a certificate issued by a public security organ, a state security organ, a prison, a reform-through-labor institution, a people's court or a people's procuratorate at or above the county level to hunt down and escort the criminal suspect for temporary detention.
There is no such certificate, or the record and actual situation of the certificate.
The criminal suspect who enters the detention center is being examined, and it is absolutely forbidden to contact anyone outside, but he has the right to meet a lawyer. Defense lawyers can meet and correspond with criminal suspects and defendants in custody.
Other defenders, with the permission of the people's courts and people's procuratorates, may also meet and correspond with criminal suspects and defendants in custody. If a defense lawyer holds a lawyer's practice certificate, a law firm's certificate, a power of attorney or a letter of legal aid to ask for a meeting with the criminal suspect or defendant in custody, the detention center shall arrange the meeting in time, which shall not exceed 48 hours at the latest.
In cases of crimes endangering national security, terrorist activities and particularly serious bribery crimes, defense lawyers should obtain permission from the investigation organ when meeting with the criminal suspect in custody during the investigation. The investigation organ shall notify the detention center of the above situation in advance.
When a defense lawyer meets a criminal suspect or defendant in custody, he can understand the case and provide legal advice. From the date when the case is transferred for examination and prosecution, the relevant evidence may be verified with the criminal suspect or defendant. Defense lawyers are not monitored when meeting with criminal suspects and defendants.
