Right now, Qingshui High had two school blocks. They faced South and were split into East and West blocks. They occupied the East and West sides of the school's main road respectively.
The West school block housed Grade 10 and 11 students whereas the East school block mainly housed the Grade 12 students with the exception of some Grade 11 students.
After pushing through three consecutive lessons, most of the Grade 12 students would choose to head to the corridors to take a breather. The breaks allowed them to chit-chat, relax, and in turn, maintain clear heads.
Since classes had just ended, it was the time when human voices echoed throughout the entire campus. Students packed the corridors of every floor. Some were talkative, some in deep thought, some were looking in the distance, and some came out to head to the restroom. It was packed with people to the point that shoulders and heels were always in contact with one another.
