When an opponent delivers a series of punches at a practitioner of the Original Li Style Feng Shou-Kung Fu. The practitioner has a vast amount of defensive hand methods (Shou Fa) they can use to deflect the in-coming blows away from their intended target, but it is important that the practitioner remains in contact with the opponents limb using their sticking (Nian) and adhere (Zhan) skills to listen and feel for the opponents direction of strength and pressure. Once the practitioner has made their contact with the opponents striking limb using their chosen ward off method, it is important to take control of one of the opponent joints on the striking limb, either the wrist, elbow or shoulder, this will limit your opponents ability to respond with another attack.
We are taught in Feng Shou-Kung Fu that taking control of your opponents striking limb below their elbow will manipulate their upper body to tilt forwards, backwards or to either side. Whereas, controlling their elbow joints will control the opponents ability to maintain their balance. For example if I was to use an outside arm ward off to deflect the opponents punch, making contact on the outside of their elbow, then I slide down their arm to their wrist for which I then grasp and pull, there upper body will be pulled and tilted forwards from their waist, for which I could then lead them onto a counter strike of my own.
If I were to make contact with the opponents elbow joint on the outside of their punching arm. I could then manipulate their elbow by adding pressure to the outside of their arm forcing it across their body that twists and rotates their whole body causing them to lose balance. Obviously there are many ways that the practitioner of the Original Feng Shou-Kung Fu can manipulate the opponents elbow joint to control their balance and leading them into counter strikes, kicks, joint locks and throws.
Every defensive hand method that a practitioner of the Original Feng Shou-Kung Fu uses to deflect or ward off the opponents attacks. Can also be methods of entering into the opponents defensive space, but only if they are used intelligently by each practitioner, by controlling and manipulating the opponents punching limbs joints to limit their mobility. To many practitioners of the Original Feng Shou-Kung Fu simply use a particular ward off to deflect the opponents blow away, but have no intention in remaining in contact to the opponents limb to control and enter deeply into their defensive space.
