The last technique is Push.
I feel that Push is a mistranslation of the Chinese term An but that’s another story.
Here’s how to do Push :-
Push is often perceived as a double palm attack but it can well be a single palm attack.
Separating the hands comes before Push. This is a neutralizing movement and can be used whether on the opponent’s side gate or inside gate.
The hands after separation on the side gate can attach to the opponent’s arm to repel him. Alternatively, if on the inner gate you can attach the hands to the opponent’s crook of the arm. There you can jerk him off balance, followed by the double palm attack.
The energy of the double palm attack is like that of a pouncing tiger. To generate this power you must learn to coordinate the movement of the wrist-elbow-shoulder and waist-leg in the manner of a hammer hitting a nail.
