This is my first time going into a prison.... This is one in Central HK, which has a long history. It has been made empty and is now used for selected design/art exhibitions. Frankly, the first impression was kinda cold. There are some dark rooms which you can imagine what would take place in there. Seriously, I wouldn't expect so many detailed rules in the area. It's a nice and quiet place but too much history and happenings.
