A prominent feature of Wing Tsun kung fu training is defending and attacking at the same time. Wing Tsun’s hands, located at the center of the chest, go out to meet the attack simultaneously in some long-range applications. In other applications, a bridge is established microseconds before the fight is underway to establish the direction, the power and speed of the attack, as well as the posture, tension and even the attitude of the attacker.
In some instances, a simple straight-line thrusting punch is all that is needed. This is the ultimate in simultaneous defense and offense.
The backup to this approach can be bong sau (wing arm) which is an arm which bends like a green branch of a sapling tree, followed by the punch, pinning hand-punch (gum dar), or edge of the hand strike (fak sau).
