When her best friend died from leukaemia last year, Ran Jing made a promise to herself; she would travel to Tibet as soon as she graduated from high school. Her classmate had been a Buddhist, and it had been her dream to see Lhasa.
A few months after her 18th birthday, Ran set off alone from her home in Henan province, taking buses and sharing cars, on a pilgrimage to the Tibetan capital in memory of her friend.
