This is the entrance to the school.

The office is to the the right as you come in.  Nowhere near as nice as Dun-San.

Bub-Dong has two hallways, with classrooms down the center and on the outside of each hallway.  That first door on the right leads into the teacher's lounge.  This is one of the unusually quite times in the day.

This is a stereotypical classroom in Bub-Dong.  This is the room I taught most of my classes in.  All room have windows on either side that show the hallway, other classrooms or the outside world.

This is the teacher's lounge.  A lot smaller, and with less storage space than Dun-San, which doesn't really make much sense since they have twice as many teachers.  But that's my spot where my bottle is and I sat on the far side of the couch.
