Tenzin Tsedring's dream job is apt, given the Tibetan teen's studies under a scheme aimed at training more professionals for the underdeveloped region.

The student of a Beijing school for the Tibetan ethnic group wants to become an engineer, "preferably in the environment sector in my hometown".

"Every time I take a train back to Lhasa, I'm shocked by the garbage along the railway line. I want to do something to improve the plateau environment," she said.
