A great escape changes one student's life

Wearing a loose, white tank top, skintight trousers and a pair of flip-flops, 26-year-old Li Tian presents the aura of a hippie, with long black hair casually flowing past her shoulders.

Last July, she gave up her five-year doctorate study at Tsinghua University after careful consideration and negotiation with her parents and supervisor.
