At the age of 17, a tender Ching Ying started a carrier as a martial art coach and stuntman for the Shaw Brothers Studios. Due to his slender build he was often called upon to substitute actresses, as it happened in his first film he really appeared on screen, in 1970. He was chosen to double for the ultra cool Cheng Pei Pei in the film called Gold Sabre Big Hero and he played a young monk as well. His salary was 60HK dollars a day, 1/3 of which went to his mentor, another 1/3 he took home to his parents. The remaining 1/3 he treated his brothers to snacks, but sometimes he got them out of the hole. He was always considered as a generous person. He once mentioned those were his happiest days in his life.
These years' experiences at The Shaw Brothers made him sufficient to undertake more significant piece of works. Gradually he had a good credit as a reliable action choreographer and stuntman.
After two years of apprenticeship he switched over to a new budding studio of Golden Harvest. His good old acquaintance Sammo Hung worked there, though their fate haven't totally entwined yet, as Ching Ying got a personal invitation from Bruce Lee himself to work for him as a stuntman and actor in his new film called The Big Boss.
Ching Ying didn't say an ultimate farewell to the Shaw Brothers company, as he was often called as a stuntman and got minor roles (generally baddies, henchmen) even in the late 70s.
