a common misperception is that all "hung style" / "hung fist" is related to the Wong Fei Hung / Tiger-Crane lineage
There are literally hundreds of different versions of "hung style" almost to the point you begin to think "hung style" was a generic name back in the day
My personal belief is that it indeed was almost "generic" because there are three characters all pronounced "hung" and associated with various martial arts traditions in China. There is of course the family name but there is also "hero" and "red".
The "red" is particularly interesting if you examine the relationship to secret societies and underground activites. The "Hung Gwun" or "Red Poles" were the enforcers of these groups, their martial arts technical "Hung Gwun Kyuhn Seut / Fat" (Red Pole fist/martial arts techniques)... of course, when appreviated as in standard Chinese practice that phrase becomes "Hung Kyuhn" or "Hung Fist"....
