If you are not an Aaron Fan, or have ever heard of him, you are probably saying "Who is Aaron Kwok"?
Aaron Kwok is a Hong Kong PopStar (singer/dancer/actor), who has starred in many Hong Kong movies and TVB (Television Broadcast) series such as "Heartstrings" (a.k.a. "Running Through the Flames") and "Wars of Bribery" (a.k.a. "OICAC Action Team"). However, these are just two examples out of many.
Aaron has accomplished International fame with his unique individual style as an artist, in a relatively short period of time. He has gone through various transitions, since the beginning of his career to the present, which includes his singing, dancing, acting and appearance.
It was in the very late 1980's when Aaron first made his appearance as a background dancer for TVB and various artists. It wasn't until the early 1990's when Aaron's talent was discovered and that was the beginning of his career.
