What have you got against Geography teachers?
I was a geography teacher before I came to China and that didn't stop me from finding work as an English teacher in Kunming.
Says it all really. China no longer wants geography teachers or tourists as teachers.
That's my point. Geography teachers (or History, Art, Music) can only really find employment in China as English teachers. I'm an ex-Maths teacher who now teaches English.
it is possible as a foreigner to be a Geography (or Social Studies, Art, Music, Design, Maths, etc) teacher in China. The jobs do exist, though of course in smaller numbers than English teachers.
