When you begin to practice the Chinese internal martial art of the Original Feng Shou Quan-Gongfu (Hand of the Wind Boxing) you will be introduced to a wide variety of footwork or stepping methods (Bu Fa) which ch should be combined with both defensive and offensive techniques. Usually all students are taught to start their practice of the Feng Shou Quan-Gongfu using the Ladder stepping method (Ti Bu Fa) which are performed using both a short attack/ defensive stepping method and a long attack/defensive stepping method, these two particular Ladder stepping methods are linear in their actions. Whereas the ZigZAg stepping methods (Jiu Chi Xing Fa) are diagonal in their stepping actions.
When using the ZigZAg stepping method the stance that is manly used is the Riding Horse Stance (Qi Ma Shi) which allows the student to combine a series of low line kicking methods in combination with their defensive or offensive hand methods (Shou Fa). Also because the ZigZag step moves in a diagonal direction it can also be used to dodge the opponents attacking techniques, allowing the student of Feng Shou Quan-Gongfu to position themselves around the opponents back or sides to launch effective counter attacks.
Within the practice of Feng Shou Quan-Gongfu we are taught that every stepping action can be easily turned into a kicking methods (Jiao Fa) and this is so with the ZigZAg stepped no methods. When the student steps out diagonally into a riding horse stance the whole of the leg and foot can be used to apply an effective low line kicking technique such as stamping, hooking, stomping and springing methods which are used to disrupt the opponents balance, while the student attacks the opponents upper body with powerful striking techniques.
Today many practitioners of the Original Feng Shou Quan-Gongfu mainly use the more direct stepping methods of the Ladder step and do not fully advocate the ZigZAg stepping method against one opponent, but do teach it to their students when surround by multiple opponents. But I was taught that to become fully accomplished with the Feng Shou Quan-Gongfu that you had to be comfortable using your defensive and offensive techniques using any type of footwork or stepping method no matter how many opponents were in front of you.
