Legal analysis
According to China's criminal laws, regulations and rules, people detained in detention centers are basically prisoners, that is, people who violate the relevant laws of China's criminal law and are considered as criminal suspects. For such criminals who have violated the criminal law of our country, their freedom has been restricted since they entered the detention center. All personal belongings should be registered and checked, and all prohibited items should be confiscated. Although you can communicate with close relatives during detention, you need to get the consent of the case-handling organ and the approval of the public security organ. Then, if these handling organs are randomly deployed, they will decide whether they can communicate according to the relevant provisions of the law. Generally speaking, in the process of investigation, except lawyers, it is impossible for criminal suspects to be agreed. As a lawyer, not every suspect can meet. The relevant laws have been agreed and will depend on the nature of the specific case. So it's hard to say whether you can bring a letter. If you can't communicate, you can't bring a letter. It is illegal to bring letters, which will affect the investigation and evidence collection.
