It's hard to pass a judgement on other countries policy; but regardless of where you are, this penalty is a little too severe.

What Mr. Gurung did was not ideal for a teacher. Yeah, I'd be pissed to if some 12 year old good-for-nothings kept teasing me with racial slurs (and don't tell me it ain't); but if I am a teacher, I should be handling it differently; that too in a foreign country with known boundaries on speech.

Still the penalty is too severe. Hope Mr. Gurung is freed soon.
