Lang Lang is a world-class young pianist who grew up in Shenyang. He went to a piano school in Beijing when he was just eight. “You need luck,” his father said. “But if you don’t work hard, no fortune will come.”

What made him sad was that his piano teacher in Beijing didn’t like him. “You have no talent. You will never be a pianist.” As a nine-year-old boy, Lang Lang was badly hurt. He decided that he didn’t want to be a pianist any more. For the next two weeks, he didn’t touch the piano. Wisely, his father didn’t push, but waited.

Luckily, the day came when his teacher asked him to play some holiday songs. He didn’t want to, but as he placed his fingers in the piano keys, he realized that he could show others that he had talent after all. That day he told his father what he had been waiting to hear---that he wanted to study with a new teacher. From that point on, everything turned around.

He started to win competitions and then became famous at home and abroad. Lang Lang finally worked to reach the place where fortune finds him, and lets him shine.
