Him Law Chung-him (born 28 August 1984) is a Hong Kong film and television actor. Law began his acting career by starring as supporting characters in several well-known films, most notably in Mob Sister (2005), which was also Law's debut film. He later began filming for several internet and television dramas, later receiving a Best Supporting Actor nomination at the TVB Anniversary Awards in 2008 for his performance in the sports drama Your Class or Mine.
Law was born to a simple Hakka family in the New Territories. As his parents were divorced when he was young, he was brought up by his uncle who did not have any children. He has an older sister who is two years older than him. His father is a hair stylist, his mother is a make-up artist, and his older sister is a piano teacher.
Law attended Tai Po Government Secondary School where he was a member of the basketball and association football teams. He was devoted to sports—he would go to basketball practice everyday after school and football practice every weekday night. On weekends, he would hang out in football courts during the day and basketball courts at night. When Law was 16, he worked as a part-time lifeguard.
