劉家良
In his youth (ages 15–20), he skipped school to train in Chinese martial arts without his parents' knowledge. He trained at Lau Cham's martial arts school of Hung Gar discipline, which descended from Wong Fei-hung's grand student (father to Lau Kar Leung). Lau Cham's wife assisted in his training and due to the friendship and respect Liu felt for Lau and his wife, he took on the name Lau Ka-fai. As he grew up, he found a job as a shipping clerk to make ends meet. His interests had always been towards martial arts and he was eventually offered a role by Lau Kar-leung.
