Legal analysis: What if no one in the detention center gives me living expenses? First of all, whether I have living expenses is not a big problem. After all, conditions are much better now than before. At least, can I eat enough? The recipes for the whole week are written on the publicity wall, and the family members will see them. Secondly, according to the regulations of detention center and prison department, I can only spend 300 yuan a month in 500 yuan, so don't panic if I don't have any family members to pay the bill, as long as you follow the instructions and do a good job.

Legal basis: Article 47 of the Prison Law of People's Republic of China (PRC). A prisoner may correspond with others during his sentence, but he 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.

Article 48 While serving a sentence, a prisoner may meet with his relatives and guardians in accordance with regulations.
