    Who is your hero (偶像)? Why do you like the person? Cool looks? Money? A lot of talent? Shanghai teenagers say they look for more than that. Most of them say their heroes are hard-working and brave.

    NBA star Yao Ming was the No.1Chinese hero with 48 per cent of all votes (投票). Zheng Hua, a 13-year-old boy from Shanghai, told us that it was hard for him to go all the way to the NBA. He's a big star. Most of us think he is still kind and loves others after he becomes a famous star. He also helps disabled (残疾的) children.

    Jay Zhou from Taiwan is the teen's most favorite star. Liu Yan from a high school of Shanghai is one of Jay's big fans. In her sight, Jay is not just a pop star. "Jay's so kind to his mother and grandma. He takes good care of them," said Liu Yan.

    Wang Hao, from a high school of Guangdong, said he liked Zhou Enlai."He's great. He loved his people. He saw people as his own children. And he never thought he was different from others."

    Shanghai students also like US businessman Bill Gates. More than half consider him as their hero. One teenager from Beijing who likes Gates said, "Bill was not born rich. He worked hard. And he doesn't like to tell everyone how rich he is. He also has courage (勇气). He left school to start his own business."
