For sure nobody has got any knowledge of how a prison is constructed. To closely simulate a prison environment, they called opon the services of experienced consultants. Foremost among them was a former prisoner who had served nearly 17 years behind bars.

The prison was constructed by boarding up each end of a corridor in the basement of Stanford's Psychology Department building. The corridor became "The yard" where prisoners were allowed to walk, eat or exercise like the large one we have seen in Prison Break. To create prison cells, they took the doors off some laboratary rooms and  established specially made ones with steel bars and cell numbers.

Where did they place the surveillane cameras? At one end of the hall was a small opening through which they could videotape and record the events that occured. On the other side of corridor opposite the cells was a small closet which became "solitary confinement" that is dark and confining.

I have been curious about how it feels to be confined in such a small dark world with merely cold walls and no light. It is said to be the highest level of typical measure to deprive prisoners of freedom in a devastating approach.How distressful would it be? How does it relate to the classic punishement we have seen in American TVs that kids are grounded by their parents? 'Ground' is to punish a child by not allowing them to go out with their friends for a period of time. Why is this punishment not commonly seen among Chinese parents? As an introverted boy, being secluded has never been a big deal for me but how long can you endure in such a solidary confinement how long will it take to bring about psychological trauma?

What's more, an intercom system was built to secretly bug the cells to monitor what the prisoners discussed and also to make public annoucements to the prisoners.

There were no windows or clock to judge the passage of time.

With these features in place , the jail was read to receive its first prisoners who were detained in police department.
