In Dempseyās mechanics, a punch is essentially a push delivered with bodyweight in motion ā short contact, high acceleration, and an impulse designed to shock the target.
Mechanically they use the same chain (ground ā legs ā torso ā arm), just arranged for a different timing and intention.
Taiji organizes force differently.
Once contact is made, Taiji doesnāt rely on launching mass or creating impulse. It uses attaching (ē²), joining (čæ), following (é), and releasing (ę¾/å) to manage the interaction. Force is channeled
through continuous structure rather than through collision.
What looks like a push in Taiji is usually long power (éæå²), used so the other person can feel the direction and adjust safely.
What looks like a push In Taiji its often referred to as "long" power...used in demos and training to allow the other to feel it, with out being damaged.
Using "short power " å°å² (cold power), is different. It releases so quickly and cleanly that the opponent has no time to react or brace ā the effect is sudden and internal.
The outward appearance can seem similar ā just as a push and a punch can share basic mechanics ā the timing, intent, and internal organization behind long power and cold/short power are not the same.
Regarding the video:
Itās a demonstration meant to show that force can travel through the body and into another person with very little visible external movement. The changes come from internal adjustments that create pressure or torque which are released only when the connection point is established.
If you slow the video down, you can see that the partner is reacting to changes already happening inside his own structure ā not from external striking or pushing. The effect is triggered from the inside, not imposed from the outside.
