[2] Law attended Tai Po Government Secondary School [zh] where he was a member of the basketball and association football teams.

Following his Form 5 graduation in 2001, he briefly worked as a lifeguard at a private swimming venue in Villa Esplanada, Tsing Yi Island, using the money he earned to study stress and rescue diving at the Happy Valley Athletic Association.

[3] Seeing that being a lifeguard earns little income and is unsuitable to be a lifelong career, Law planned to attend a fire academy to become a firefighter.

[2] Law debuted in the 2005 Hong Kong action film Mob Sister as the boyfriend of Annie Liu's character.

"[4] Although Dressage To Win was Law's first drama to broadcast on television, he first filmed the 2008 sports comedy-drama Your Class or Mine, starring opposite Bobby Au-yeung and Sheren Tang.

Law portrayed Fan Pui-tung, a high school football player, and received a Best Supporting Actor nomination at the 2008 TVB Anniversary Awards.

[5] According to Law, filming for television dramas was difficult as he only gets two to four hours of sleep daily, but he exclaimed that it was a good way to improve his acting.

[6] Law was later cast to portray Joe Ma's younger brother in the romantic comedy drama Suspects in Love, produced by Poon Ka Tak.
