This is a full fledged Korean production that was edited into a Hong Kong version by Hwang Jang Lee and his short lived production company. There are two versions, the HK and Korean versions(recently found in Seoul Korea, which was edited personally by Hwang), which have major differences, including the fighting sound effects, a reshot and edited Shaolin temple scenes, and a finale fight with Eddie Ko that last 15 minutes longer than the HK version. The Korean version is the best, and in both versions, the music score sare excellent. The Korean version is available on the Eastern Heroes special edition DVD. Both versions are well written and the fight scenes are beautifully shot by Hwang, Mang Hoi, and Corey Yuen. **** for the Korean version/*** for the Hong Kong version/*****
