Ko is the son of the late Taiwanese stuntman/actor,
Blackie Ko Shou Liang and his wife Sung Lai Wah. For his father, he wrote two songs, each in one of his albums in the same number of track. "Wake Up" and "I Miss You". These two songs shows his relationship with his father and how much his father had changed him. Before receiving the chance to release his first album, he went through a lot of hard work. Ko was initially a guitarist who had minimal experience writing songs and lyrics. He first entered Alpha Music in 1999, where he worked as a host under
Jacky Wu's branch of artists before quitting in 2002. Ko was eventually mentored as he befriended
Jay Chou, who told him that he should know how to write his own songs, so that people would want to listen to his music. Ko began to write more as a
lyricist, including styles of
R&B,
rock music,
rap,
pop music and various genres. Ko's music director required him to edit and edit his songs, every year, every month, every week, and every day. Ko pushed harder on working on his songs for perfection despite his courage being challenged. Within six years of preparation, Ko eventually selected the best 12 songs for all the people anticipating for his music. Ko's father died of an accident in 2003, but it neither stopped him nor did he want to be like his father, and insisted on going his own route. Prior to his death, his father told Ko "to achieve success and not let him down, or else he would not acknowledge Ko as a son". On August 19, 2005, Alan Kuo's first album came out with 12 songs and gained heavy support by famous
Hong Kong singer/actor,
Jacky Cheung. Since then, Ko acted in various shows and films. == Personal life ==
