Since she was a young girl, Li Juhong dreamed of becoming a doctor. Then, at 4 years old, she lost her legs in a tragic and painful accident. But that experience didn’t weaken Juhong's resolve; rather, it drove her to help others in pain. Now, the 38-year-old is one of two doctors responsible for around 2,000 people in the mountainous Chinese village of Wadian. Armed with her medical training and a determination that often sees her work well into the night, Juhong says she feels "happy and lucky" to have helped so many people in her village.
