He fell ill with a form of arthritis of the spine at the age of five, making him unable to stand and take care of himself independently. His mother, Cheng Wumei, has been transporting him to and from school for years. Li said he will endure the famous college entrance examination no matter how hard it is. The exam is scheduled for early June this year. [Photo/Xinhua]
