     What is your favorite cartoon? It may be difficult for you to decide. But for the pianist Lang Lang,

Tom and Jerry                       .

     When Lang was two years old, he saw Tom playing the piano. This was his first time to enjoy

Western music and this experience encouraged him to learn to play the piano. His talent for music has

taken him from Shenyang to the world.

     Lang became a good piano student at the age of three. Ever since, the boy has been doing better and

better. In 1997, the 15-year-old boy studied at a famous American music college.

     Lang's performances are energetic. He is wellknown for making facial (面部的) expressions and

moving around while playing the piano. The road to success has never been easy. Lang's father stopped

his job to look after him, while his mother stayed in Shenyang to make money. But Lang thinks himself

lucky and believes he should give something back. He has helped the children in poor areas a lot.
