Really? Well then that proves my point, doesn't it? You are NOT learning traditional, but modified. Ok, if you are using traditional, then name the ten concepts? Do you know how to use them appropriately in a fight? I bet YOU DON'T! If you have to supplement it with any other style, then it is NOT traditional! Yes skill is internal, but in the case of wing chun, it is also external. It is both! See, you DON'T know as much as you think you do, now do you? I doubt others because people like YOU make me laugh, thinking you have it figured out, when you don't. Do you know the proper stance(toes slightly pigeon-toed, knees pulled in, hips pulled in to maintain the triangle, legs adducted to strengthen the link?), proper footwork (circle inside a triangle. The circle protects the groin and the triangle puts you at the correct 45 degree angle to the OUTSIDE of your opponent's defenses?), proper way to close the distance (This is done through initial contact. When the punch or kick is thrown, contact is made through a soft block and a forward ANGLED step, using your arm as a gage to distance. This is done several times until you are close enough (2 to 4 feet, depending on your height and arm length) until one last contact is made. At this point, you make contact, entering in on an angle one more time, trapping the arm and countering. If your opponent retracts his arm, then you FOLLOW HIS CENTER OF MASS IN without hesitation (THAT is from Master Wong Shun Leung, considered on of the best fighters in the 20th century), stepping again at an angle, trapping the arm and countering. Do you follow this? If not, you are NOT doing traditional. If you leave out any one of these, then you are taking out a vital portion of wing chun that makes it work properly. And FINALLY, and MOST IMPORTANTLY, learning and using the ten concepts, which, like I said before, is the guideline to wing chun's proper application in a fight or self defense scenario. THIS IS CRUCIAL IN WING CHUN to maintain it's flexibility and with this, you can tailor your wing chun to your abilities or disabilities, your personality, and to that of your opponent, which, again, is CRUCIAL to it's proper application. Get all that? Now, you were saying? Just because you learn wing chun doesn't necessarily mean you are learning wing chun. Not the whole system, anyway. And this is very important to know to make sure you wing chun works right when you need it most, in a fight or self defense situation.
