Su Xing 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.
Born in Xi'an, the capital city of northwestern China's Shaanxi, Allen Su had always been an excellent student since childhood. When he was 17 years old, his parents sent him to Sydney to pursue his study. Allen managed to study business at Macquarie University, but soon he realized that he was not interested in business and what he really goes in for is music, so he transferred to SAE College Sydney to study in digital media.
