To enhance the power of the punch in Step Up, Parry, Punch try doing this. So I said to my student before demonstrating the additional tweak that can boost the power and penetration of the punch.
Right away some light bulb went on in his head and he blurted out that this was what he thought of as more of a punch based on the reading of the Chinese character.
Yes, indeed. In fact, when we change the characteristics a bit it could well resemble the famous Xingyi half-step Beng Quan except in Yang style Tai Chi we call our version by another name. Its actually not found in the basic Yang style long form but I see no harm to tell my student about it at this stage.
The point here is that once you filter out the wrong ways of doing things and go more into the more optimal ways you might find more similarities than differences amongst styles. Hence, the importance of discarding the notion of styles sometimes.
