Question
When was jackie chan born?
Answer
In his early stuntman and acting career (prior to New Fist of Fury in 1976) he was known as Chen Yueng Lung (or Chen Yuen Lung). In his autobiography Chan states that he used this name, which is close to his opera brother Sammo Hung's opera name, so that he didn't have to put his name on film's he wasn't happy with. He was thereafter known as "Jackie", named by his Australian co-workers when living in Australia in 1976-1977. Working on a building site alongside a labourer named Jack, Chan's co-workers nicknamed him "Little Jack", and later shortened this to Jackie. Because his father's family name was originally Fong and was changed only when arriving in Hong Kong, Chan's Chinese name was changed in family records years later to "Fong Si Lung". He has also been listed as "Sing Lung" (meaning "already a dragon" in an attempt to jump out of Bruce Lee's shadow), particularly in relation to his music and it may be no coincidence that his character in the film Fearless Hyena was called "Shing Lung".
