     His songs are a bit sad, but his boy-like smile can quickly warm you up! And people love A-do for both

reasons.

     He has been singing for only two years, but he's already a famous star in Asia's pop world. The Singaporean

singer has already made three albums. Together they have sold more than five million copies across Asia.

     China's Music Radio named him "the Asian King of Pop". A-do said he didn't expect the award (奖)."It's

great for me. It makes me want to work even harder."

     His new album "Hello" came out in December. He sings with the same rough (粗糙的) voice, and he puts

in some rock music. In the "Hello" music video, Vicky Zhao (赵薇) is with A-do outside on a cold day in

Northern China.

     A-do used to be a house builder. Every day after work, he would sing by himself. Other workers heard

him and told him he should be in a contest.

     A-do hasn't changed much. He still gets nervous in front of cameras. Peng Yiting, a junior at a middle

school, says, "He's real and doesn't show off (炫耀). He's an everyday hero and shows anyone can do well

if they work hard."
