One of the most underrated defensive & offensive hand methods (Shou Fa) taught within the Li Style Feng Shou-Kung Fu I believe is the “Cloudy Palm Method” (Yun Zhang Fa). Many practitioners who study and practice the Li Style Feng Shou-Kung Fu only teach the Cloudy Palm as a defensive technique to deflect in-coming blows away from their intended target. But the usefulness of the Cloudy Palm Method is to use the back of the wrist and back of the hand as a hooking technique that can be used skilfully to trap and move the opponents limbs, creating better lines to attack with powerful striking techniques.
As with every defensive & offensive hand techniques that are taught within the Li Style Feng Shou-Kung Fu. They can be used in a singular, double or changing hands methods and so it is the same when using the Cloudy Palm Methods. As a defensive tool the Cloudy Palm can be used to defend against high or low blows that come from various angles, such as hooks, straight blows, uppercuts etc. When using the Cloudy Palm Method to defend with it can not just be used to deflect blows, but it can also be used to remove an opponents guarding limb out of the way, if it is in the way of your line of attack, or it can be used to trap and pin your opponents limb.
Primarily the Cloudy Palm Methods can be used to open up your opponents defence by either entering from the outside to inside or vice-versa. It can also be use to hook the opponents wrist to pull the opponents arm downwards from a high line to low-line position or the Cloudy Palm can be used to hook the opponents elbow joint and pull it in an horizontal direction to create an opening line to attack the opponents body. The Cloudy Palm Method is a great tool to have and develop if one knows how to fully use it other than just as a method to deflect blows away, but knows how to use it to remove obstacles to enter deeply into your opponent defence.
As with all of the defensive and offensive hand methods that are taught and practiced within the Feng Shou-Kung Fu System they can all be used alongside striking methods (Da Fa), kicking methods (Ti Fa), wrestling methods (Qin Na Fa) and throwing methods (Shuai Fa). And so it is the same when using the Cloudy Palm Methods to defend against an opponent.
