A student has overcome losing nearly half of his body in China's massive Sichuan earthquake to become a top swimmer.When the roof fell in on his school in Beichuan three years ago, Dai Guohong's legs were crushed under tonnes or rubble that killed 26 of his classmates.But after a series of operations, Guohong, now 18, was picked by local disabled sports chiefs to train as a Paralympics swimmer and is coming to compete in London next year."I didn't have any professional swimming training before. But doctors said swimming is good for the body, so I went to have a try," he explained."I just seemed to take to it because of the freedom it gave me to move. Suddenly I wasn't disabled any more. I can't wait to get to London and show what I can do," added Guohong.Source: orange.com
