Detention Class 留堂！

I was looking at my old sketchbooks and found this which I think is quite special!  This old sketch was done in 2006 when I was working in a secondary school. I was on duty looking after a detention class and I sketched many of the students as the students were asked to copy classical literature for hours as punishment!  What do you think?

一張舊畫！當時我在一中學任教，此畫是在課後留堂班中畫的。留堂的同學都要抄寫古典文學作品直至留堂班完結。
