Flying Crane
Sr. Grandmaster
Exactly what I was going to ask. Maybe not 'chi sau' exactly, but surely there are two-person drills that incorporate the system's ideas of movement and principles?
I train Tibetan White Crane and we have a chi sau drill. It's very differnent from Wing Chun's chi sau, but we call it the same thing.
So yeah, I think whether by the same name or by another name, there ought to be some training method in there that accomplishes the same thing.
