For some there is a difference between Hung Kuen and Hung Ga.
Some view Hung Ga as a more family oriented system based almost exclusively on the teachings of WFH.
They view HK as the original system before it was modified by WFH.
Not sure how much there is to that and don't really care all the much to be honest.
But I do notice that the HK I do from my lineage in Macao doesn't always "add up" the the WFH lineages.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
