Lo joined the film industry in 1976, and soon caught Chang Cheh's eyes. He starred in 18 of Chang's films within five short years, with The Five Venoms and The Kid with the Golden Arm as two of his signature performances. In the 1990s, Lo began to develop his second career in TV. He was widely accepted by the audience after joining the prominent Hong Kong TV station TVB.
Lo has recently changed his name to Lo Wang, and is trying to re-position himself rather as a comic actor. At present, he is mostly seen on television and local showbiz circuits.
