Su Xing (simplified Chinese: 苏醒; traditional Chinese: 蘇醒; pinyin: Sū Xǐng; Allen Su; born March 5, 1984) is a Chinese singer, songwriter and actor. He took the 2nd place in the 2007 Super Boy 快乐男声contest, which was a national singing contest for young male contestants held by Hunan Satellite Television. Although he was only 23 years old while participating in the contest, Allen appeared much more sophisticated than many other young men of his age. After winning second place in the contest, he released his first EP, including six brand new songs, of which two of them were written by Allen himself.
