Please help those who have been to Da Lang detention center. . . very urgent

The six questions are as follows:

1. Do I need to shave my head when I enter the detention center? (not needed)

2. What about being detained for 15 days? (Eat, sleep, sleep and eat)

3. Do you need a job? (If the prison guard takes it, he will do it. If he doesn't take it, he won't have to do it. )

4. Basic life? (Not hungry, not enough to eat)

5./kloc-will you come out in 0/5 days? (The detention book has the date of detention and the date of release. If it is criminal detention, it will not come out for a while, and the chances of sentencing are quite high. )

6. Can I make a phone call inside? (If you are looking for a relationship, you can bring your mobile phone in. )
