Leave a few prison relatives behind.

According to the inquiry of China Travel Service. Com, no more than three prison relatives. According to the law, criminals can communicate with others while serving their sentences, and the home number is based on the telephone number registered at the time of admission. People who talk to criminals, only their relatives, should talk for ten minutes.

Legal basis: Article 47 of the Prison Law of People's Republic of China (PRC): A prisoner may communicate with others during his sentence, but the communication shall be inspected by the prison. Letters found in prisons that hinder the reform of criminals may be detained. Letters written by criminals to higher authorities and prison judicial organs are not subject to inspection.
