Really have no desire to feed into this, or get into a detailed discussion with you on something you are attacking, do not understand, and are using silly videos to make your point. Spent years in security, hospitals, college and government, months of that working for a hospital with a mental health and detox unit, I stopped tracking physical confrontations after 60 in 3 months, used many things I learned in Taijiquan, mostly redirecting force and qinna. Have no idea if Qi had anything to do with it.... There is no projection of "Qi" in traditional Taijiquan, and the claim by anyone doing so is considered rather silly. Best description of Qi (internal energy) I have ever heard is, strong Qi you're healthy, weak qi you're sick, no Qi you're dead.
As for the video you show, first that is not push hands, push hands is a training tool, not sparing, not fighting. So your comment, based on that video, are not applicable to my post about push hands, since that is decidedly not push hands.
You really do not seem to know what you are talking about here.
