Energy Principles Give up your own Force (捨拙力-捨棄不必要之力量) One needs to be relaxed in order to move dynamically and to react to the actions of an opponent. When you are tense, your "own force" acts as a parking brake -- you must disengage it first before you can move quickly. Get rid of your opponent's Force (卸來力-卸減他人來攻的力量) This is similar to the third fighting principle. When an attacker wants to use strength to overpower a fighter, the response is not to try to overcome strength with strength but to nullify this force by moving your attacker's force away from you or to move yourself away from it. Use Your Attacker's Force against him (借他力-來留去送) Take advantage of the force your opponent gives you. If an opponent pulls you toward him, use that energy as part of your attack. Or if an opponent pushes the left side of your body, you can act as a revolving door and use that force in an attack with your right arm. Add Your Own Force (施巧勁-甩手直衝) In addition to borrowing power from your attacker, you can add your own force in an attack when your hand is free.
