Visitors from China and one of our students at our Classical Tai Chi class Buffalo State College. What we do with this "small frame, small circle" Tai Chi is really not known in China. This after talking with our visitors and then our Master Stephen Hwa For example, they told me my pronunciation was good but they don't understand that things like "Neigong* really does come from the abdomen and back aka "core". Their perception only extends to it simply being a "mind/body" disciplineDoing the Lions share of repairing the hole where logical reasoning disappeared, "righting the ship" and saving Tai Chi.

A push is no push unless it's ordinsry

Note that Tom is going upward as well as going backward with the punch. In light of that, I would not bet any money make the stereotype remark and say this is a "push".  If it was a push then Dr. Hwa would be pushed back by a reaction force. "Push" yourself back from the wall for yourselves and note the reaction. The reaction force from a push is a hallmark of ordinary force. The reaction force of ordinary force is also in accord with Newton's 3rd Law. You know this as every action having an equal and opposite reaction. He is doing a punch that uses 1/4 body internal discipline. There would be a reaction force if his punch did not adhere to the following path: Relax arm,  Tense arm, Relax the arm and he is able to do this because force comes from the core and not external (arms and legs). So, is his 1/4 body "punch" in violation of Newton's 3rd law or not?   There is logical and scientific reasoning at work here. In Classical Tai Chi We are doing Lion's share of repairing the hole where logical reasoning disappeared, "righting the ship" and saving Tai Chi.
