(i thought i'd revive some old threads!) some of what they are doing is taiji, however, much of it is straight external shaolin or wushu. just look at all the force-against-force blocks! if they used taiji 100% of the time they wouldn't block any attack dead-on, they'd blend and redirect as they do the rest of the time. fun to watch anyway. there's way too much standing still in one spot in a wide stance for my taste. and still very wushu/theatrical in that they land a blow but don't follow up to finish off the opponent. thanks for the entertaining link!
The only purpose in reviving this thread was to remind us that Gerard has gone off to live in a Jin Yong novel.
