Four Doors Four Gates http://www.tigerandcrane.com.au/photos7.htm http://www.tigerandcrane.com.au/images/ph-4gates.gif The areas of the body to which an attacker may strike, or a defender may block, are divided into the four gates. The above illustration shows that the body can be divided into upper, middle, lower and sub-gates. Below the knee, or sub-gate, a leg check will be used to effectively block, since an arm/hand block to this lowest gate will put the defender off balance and out of stance. In ATAC Kung Fu, punches and kicks to the upper three gates can effectively be blocked by hand techniques. Reciprocally, attacking punches and kicks are applicable to certain gates e.g. side kick - middle gate Chinese front kick - sub gate Tornado kick - upper gate The doors of ATAC Kung Fu represent the directions from which an attack or defence may emanate: e.g. FORWARD or TO THE FRONT REAR or BEHIND TO/FROM THE LEFT SIDE TO/FROM THE RIGHT SIDE
