When Cathay wanted to end the company's association in Hong Kong, Chow left Shaw Brothers to establish Golden Harvest along with film producer Leonard Ho in 1970. He capitalized on the shortcomings of Shaw Brothers, who had a system that limited creativity, and was able to lure Bruce Lee into Golden Harvest, making it a serious competitor to Shaw Brothers. Under Chow's leadership, Golden Harvest would become the cornerstone for Hong Kong cinema leading Hong Kong box office sales for two decades from the 1970s to 1980s.
