I wasn't backing you up re the hips in Wu style. Wu style leans, flexes their pelvis.
Can you imagine what that might do to a helpless spine. Especially if you twist it at the same time.
Anyways, don't worry about putting the twist back in.
Bart Saris has found it hidden under his master's big belly.
Here's what he says:
"A last example of how things sometimes happen concerning the turning of the waist, comes from my own experience.
Before becoming a student of master Ma Jiang-Bao and the original Wu style, I had been practicing Cheng Man-Ching's simplified Yang form for some 5 years. At that time Ma Jiang-Bao, Wu Chian-Chuan's grandson, was still teaching in Düsseldorf, Germany. Until then people like Benjamin Lo and William Chen had been my t.c.c. role models. In the Yang style version they practice, the archery stance is an upright one and the body from the hips upward is moved as one whole under the slogan "turn, don't twist". The shoulders always have to be on the same plane as the hips, so I was taught.
During the first almost 2 years that I followed master Ma's lessons, I did not even notice the difference in the way he moved! Though he would frequently mention during instruction that "the waist" had to be turned, which meant that the upper body had to be turned by twisting in the waist area, I automatically translated that for myself into "turn hips plus upper body". Of course Wu style t.c.c. did not feel very comfortable as a consequence! When he showed the movements, the fact that I changed them into something entirely different escaped my attention completely. Apart from my having been wrongly programmed, there were two other reasons for this. First of all, master Ma is a fairly large and above all sturdily built person with a big belly, behind which the turning in the waist area is partly hidden. Besides, it is not the case that, while twisting in the waist area, the hip area is forced to be immobile. It rather loosely follows the rest of the body. In the movements the twisting of the waist area functions within the sequence "hand-trunk-foot/weight". Taken together it was difficult for my biased eye to see exactly what happened. Also the issue did not have master Ma's special attention at that moment, because of the way he structures his lessons."
Now, it appears, we have the hands leading the body.
So, many ways to do it and so many ways to arrive at the right one.
The master's clearly don't say do it anyway you like, do they?
So, when different masters do it differently, who do you wish to follow?
What did you conclude from looking at Chen Fake?
