http://www.youtube.com/watch?v=O2W2tW1M9gAIt is always fun to watch his moves and apps. in the clip, he used some examples or final postures from tai chi.
he was saying or proposing that we always have to think about apps for defense, hitting/striking, qin na and shuai or grappling and throws all the time from all postures.
for example
1. Peng, left forearm upward peng, and right hand around the waist.
This is the final posture, but we may use the same posture for defense, striking, grappling and throw. He showed these apps sequentially in the clip.
2. Lu or 2 hand lu downward posture or just double downward pushing palms or down ward sealing hand posture
again defense apps, strikes apps, grappling and throwing apps.
3. Ji posture
4. An posture or double pai zhang (tapping palm) or pa zhang (climb palm)
defense apps, strikes apps, grappling and throwing apps.
He called them 3 principles of MA
1. defense uses
2. strike uses
3. grappling and throwing uses.
I guess he just used them to illustrate his points.
