An armless pianist who plays with his toes has won the first series of China’s version of the internationally popular TV talent show, “China’s Got Talent.”

Liu Wei, a 23-year-old Beijing-born pianist, who lost both his arms at the aged of 10 when he was electrocuted(触电)during a game of hide-and-seek. Liu Wei stayed in rehabilitation(康复)centre for 2 years. When he got out, he was introduced to Beijing’s disabled swimming team, and he managed to take 2 gold medals in the National Disabled Swimming Championship at the aged of 14. But soon he was told not to do too much sport by the doctor.

Liu Wei was very sad. Luckily, the door was shut on sports, but it opened in music. At the age of 18, he started to learn the piano.
