The given maps illustrate the changes in a room over 5 years.
Overall, it is clear that the room underwent significant development, with increasing study tables and establishing a new thing being the most notable transformations. In addition, the audio room and conference room were removed during this period.
5 years ago, the room consisted mainly of four study shelves in the center of the room and 3 rooms in the left corner of the room. At the top of these 3 rooms was a classroom, while at the bottom of these was a meeting room and last was book information. There was also computer books in the opposite corner to these 3 rooms, with an office in the southeast corner of the room. On both the north and south of the building were located book shelves, and near to the south book shelves was the entrance.
By now, however, considerable changes have taken place. The classroom was replaced by an audio room, and the office gave way to a conference room. Meanwhile, the study tables remained unchanged, but they increased to 6 tables, and a new printing machine was constructed in the southwest corner.
