Liu had been interested in acting at an early age, and decided to enter the film industry after graduating high school. He took on various
film crew positions to accumulate industry experience, and was initially rejected from acting school because of his height and "ordinary" appearance. He was eventually accepted into the
TVB artist training programme in 1979. Liu was first known for his appearance in the hit 1980 TV series
The Bund. Liu continued to work with Lam on a number of films including
The Sniper and
The Stool Pigeon, the latter of which earned him another nomination for Best Supporting Actor in 2011. In 2014, Liu was cast in a leading role for two
Hong Kong Television Network drama productions,
The Election and
The Borderline. The two dramas were selected in a public poll for their online launch on 19 November 2014. ==Personal life and death==
