The principal and the teacher, Teacher Yang, are such cardboard cutouts of authority figures, aren't they? The principal is all about reports and procedures, while Teacher Yang is just flustered and ineffective. And the way the butler shows up, stammering about "no, yes, no," is hilarious and sad at the same time. It really drives home how absent Liang Liang’s parents are. Money is the only language his family speaks. The whole scene in the meeting room feels like a parody of a disciplinary hearing, with the kid just swaggering in and insulting the teacher.
