What’s your favorite cartoon? It may be difficult for you to decide. But for pianist Lang Lang, Tom and Jerry is the best one.

When Lang was two years old, he saw Tom play the piano. This was his first time to enjoy western music and this experience encouraged him to learn to play the piano.

His talent at the keyboard has taken him from Shenyang to the world. Lang became a good piano student at 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 well-known for making facial （面部的）expressions and moving around while playing the piano.
