It's not that we can see the case only after closing it. You just can't see it until he wrote an interview form in it after the verdict. Each interview will not last more than 30 minutes. (I was detained by Zhangjiang detention center for drunk driving for two months and just released) It is not recommended to bring a note. The best way is to hire a lawyer. The lawyer can bring a letter to your boyfriend, and your boyfriend can also write a letter to bring it out for you immediately. If you find the hidden note, you can't send clothes and money in the future.
I hope I can help you.
You don't understand downstairs. Don't talk nonsense Where did the prison guards come from? The prison guard was called. Detention centers are used for discipline. Unless your social relations are in place and the detention center is not in the police station (you are a great god), let the discipline take a message for you. I have more than 8000 detainees in that detention center. Seven prisons. Four floors. Go shout!
