At 8:50 p.m., in the library of the Rose Iron Prison Core Zone, more than half of the reading room seats were occupied by inmates quietly flipping through books under the watch of the guards, with only a few near the bookshelves whispering to each other as they searched for books.
During the evening in prison, there was a short period of time designated for inmates' free activity. Although called "free" activity, it actually consisted of limited options such as attending extra skills courses in the education room or visiting the library to read books, all under the constant supervision of the guards.
Many inmates chose to go to the library, as reading was one of the few entertainment options allowed in the prison. The reading room was also much brighter than the cells, and as long as one had a normal treatment grade, one could typically choose to sit in the reading room in the evening and then borrow one or two books to continue reading back in their cell.
