I just got my hands on a very old magazine article (official karate, feb 1976): "Pat Mei Kung Fu, designed for fighting". It is about a west-coast pak mei school lead by a sifu Patrick Lee. Lee states in that article, that originally there were only 4 Pak Mei forms, but since they were very difficult to learn, other forms were added to make it easier for the students. So now my question would be: What were the original 4 Pak Mei forms?
