Using qi

Qi alone is not going to defeat anyone. If it could, why bother to learn the system? Why not just hit people with your qi?

To apply tai chi effectively in combat you have to learn pretty much all the same skills you would learn in any martial art, but with a twist.

Unlike the external arts, your focus will be upon whole-body movement, softness, gravity, sensitivity and going with the flow. There is no holding, blocking, bracing or forcing of any kind.
