Right, Quan Sao, there are NO SECRET MOVES in wing chun. The only moves that people consider "Secret" are the ones they don't know because their CRAPPY MODIFIED SYSTEM doesn't teach it to them! I take TRADITIONAL wing chun, and it is a COMPLETE system, and has all the key elements that make wing chun work left in. This is NOT the case in modified. As the name suggests, it is missing elements like proper footwork (the circle inside the triangle), PROPER way to close the distance (using initial contact to either push the opponent's hand past his center, causing an opening you can exploit, or you can either maintain contact and close the distance or if contact is broken and you are close enough, ENTER IN and trap the arm and leg and finish the fight), and the TEN CONCEPTS, which, many of you do not know, is the GUIDELINE for the proper application of wing chun in a fight or self defense scenario. Without the ten concepts, your wing chun will be stiff, rigid and LIMITED IN IT'S RESPONSES! This is why ALL ten concept must be used EVERY TIME YOU DO YOUR WING CHUN! This allows flexibility in your response, and allows you to go up against ANY system, even one you have never seen before, effectively, as long as you adhere to the ten concepts, and know the whole system, including the aforementioned proper footwork and proper way to close the distance, using an ANGLED step with a body rotation square, to the outside of the attacking arm, putting you out of reach of his counter and putting you in a great position to counter. Those "secret moves" they are talking about comes from the third form, bil sau. It is the "EMERGENCY" form that gets you out of severe trouble when you either make a mistake, or you have been hurt, and allows you, hopefully, to go home in one piece. The reason why they say it's secret is because most do not get that far in their training to learn this, along with the locks and throws, weapons, and the new wing chun grappling system called Biu Jitsu, based on the same third form.
