I need your help finding a kung fu movie!!!

[Guest rlerma21]

Its the very first kung fu movie i ever watched. It was back when i lived in the philippines in the mid 80s. I watched it on tv, i think it was made in the 70s or 80s. Most of what i remember is the final fight, but the Basic plot is the main character sets out to kill the bad guy who killed his master. he saves a girl who helps him fight in the end. I think when he saves her he had to fight a bunch of girls, and she gets released and helps him fight. The last battle is the girl and the main character fight fight the bad guy. then in the middle This guy with long black pants and long hair comes and all three fight the bad guy at the same time. I think in the end the bad guy kills everyone except the main guy, who beats him. sorry if this was too stupid or general a description, but i watced the movie when i was 6 or 7.
