Although Qin Na techniques from one Gongfu style may seem quite different from the techniques of another style, the theories and principles of application remain the same. These theories and principles form the root of all Qin Na techniques. If you adhere to these roots, your Qin Na will continue to grow and improve, but if you ignore these roots, your Qin Na will always remain undeveloped.
First you should understand that there is no technique, which is perfect for all situations. What you do depends upon what your opponent does, and since your opponent will not stand still and just let you control him, you must be able to adapt your Qin Na to fit the circumstances. Like all martial arts techniques, your Qin Na must respond to and follow the situation; techniques must be skillful, alive, fast, and powerful. You should further understand that Qin Na must take the opponent by surprise. In grabbing Qin Na you have to grasp your opponent's body, and so if your opponent is aware of your intention it will be extremely difficult for you to successfully apply the technique. In such a case you may be obliged to use a cavity strike Qin Na instead of a grabbing technique. Click to learn how Chinese medicine treats Amenorrhea.
It is usually much easier to strike the opponent than to control him. Subduing an opponent through a Qin Na controlling technique is a way to show mercy to someone you do not want to injure. To successfully apply a grabbing Qin Na, you often need to fake or strike the opponent first to set him up for your controlling technique. For example, you can use a punch to cause your opponent to block, and when he blocks, you quickly grab his hand and use Qin Na to control him. Alternatively, you might kick his shin first to draw his attention to his leg, and immediately grab his hand and control him.
