The maps illustrate how the rooms have been changed over the past five years.
Overall, the room has largely preserved its original design, with only a few changes made. Additional tables and a printing machine were installed, and a new conference room was created.
More precisely, five years ago there were four study tables in the center of the room. The classroom and the book information area were situated on the left side, with meeting room located between them. There were two bookshelf areas, situated at the bottom and top sides of the study tables. The office was positioned in the bottom-right corner, with the computer bookshelves located above it. The room had only one entrance, which was positioned between the printing machine and the conference room.
By contrast, although the room has largely preserved its original style, minor changes have been made. These include the addition of a printing machine just below the book information area and two extra tables. Furthermore, the classroom has been converted into an audio room, and the office has been transformed into a conference room.
