exchanges happen but every choy lay fut school does the chop choi with a panther fist. I don't think emphasis on the chop choi/panther fist means buk sing influence.
In my honest opinion, i believe it was indeed Tam Sam who inspired the use and research into the different usages of the chop Choy with panther fist. Original/OLD fut san hung sing kuen (CLF) did our chop choys with solid fists. a few fut san hung sing lineages still do till this day.
all choy lay fut schools have these techniques.
true. but its about the usage and personal experience the old masters based their usages on.
