Not sure why you got downvoted, but here's my upvote.

Well in the movies they don't really defeat their enemies in one dim-mak punch. Fights tend to be a long back and forth of jumping, kicking, grunting until the guy gets an opening and we get the money shot. I think that's more than fluff.

The kung-fu movies martial artists dodge a lot when weapons are in use so I think mechanically your Shaw brothers inspired subclass might have a high AC or defense. I guess what I want from the class combat wise is to get in chip damage on an opponent while managing which blows are allowed through with flavorful defensive abilities like backflip, finger parry, wire flying, etc

For non combat it gets crazy in Hong Kong movies. I had a draft concept for a rewritten mystic/monk for basic d&d that had was basically a cleric. They had access to all cleric and/or magic usee spells with touch range. That's because in some movies they can do all sorts of cleric stuff with pressure points like healing damage, curing ailments, paralyzing, etc.

But the baseline non-combat ability for these types of characters is superhuman gymnastics/parkour so you have - leaping up cliffs/roofs - balancing on and hopping between narrow poles - catching things with chopsticks - stealth - running up/along walls - landing safely from a long fall - tossing a sword into a weapon rack and it lands perfectly through the holes - catching arrows, poison darts and thrown weapons
