The Jackie Chan directed and starred film CZ12 invited Emil Chau Wa Kin to sing the trailer theme song. Their previous collaboration was TRUE HEARTED HERO in 1993. The song was based on Chang Chen-Yueh's song with new lyrics about life philosophy. Jackie Chan went to Taiwan for the recording as well as the music video shoot. During the shoot Chau Wa Kin's "lyric forgetting disease" spread to Jackie Chan, the team prepared cue cards so the shoot went smoothly. Jackie Chan said that when he sang TRUE HEARTED HERO with Chau Wa Kin he was able to step foot into the music scene. This song also became his theme song. He finally understood why Chau Wa Kin did not invite him to collaborate for so many years. Jackie Chan joked, "If I keep singing, he will be unemployed!"
