Liu Wei is very famous in China because he can play the piano with his toes(脚趾).
One day when Liu Wei was only 10 years old, he played a game with some friends. He lost
both his arms because of electricity.
Liu Wei was very sad when both his arms were cut off after the accident. But soon he had to
make a choice.
“For people like me, there were only two choices. One was to give up all the dreams, which
would cause a quick death. The other was to work hard without arms to live an excellent life.”
says Liu Wei.
Liu Wei’s dream was to be a pianist. He learned to play the piano with his toes. And teaching
himself to play the piano with his toes was very hard. Many times he wanted to give up, but his
parents went on encouraging him and he wanted to make his parents proud.
