Yin Fan, 24, a post-graduate student at Anhui University and a cornea donor, said she used to think donating would be bad luck. But she changed her mind after seeing many helpful cases. "What I do will be a kind of contribution, although it won't be helpful anytime soon," said Yin, hoping she can inspire her fellow students. Photo was taken on Dec 4, 2012.[Photo/Xinhua]
