Recently came across a video of a (relatively unknown) Malaysian CMC-style teacher called Lee Bei Lei (aka Lee Bian Lei):
The reason I'm posting it here is because the teacher and his material seems so much more martial in focus than the vast majority of CMC taiji out there. Some of the 2-person drills, applications and push hands look pretty interesting too.
Particularly amusing to see the guy in the video (who IIRC was a student of Donn Draeger) try to put wrist locks and arm locks on Lee to no avail.
Does anyone on this board know more about this branch?
