"Wong Shun Leung said that when you punch the head the brain hits the side of the skull. If the brain is against the side of the skull and a second hit follows, then damage and a knockout results because there is no cushioning possible. This is why Wing Chun has its rapid fire punches instead of the pull back approach."

“VING TSUN KICKING METHODS , by Clive Potter”

“Against a strong kicker there are two ways to fight. If you are experienced, just go into their center and hit. But if you aren't, then back up. Each time the opponent misses, he will lose one degree of confidence. After a while you have more chances.”

“In training Biu Jee we are taught to be free . The first forms tell us about normal situations. Biu Jee is for the abnormal situations . The ideas in Biu Jee sometimes will contradict normal Ving Tsun ideas in order to allow the person to survive in a bad situation . We are told to do what is necessary to survive and so there are no limitations . Styles have different concepts and objectives . With Ving Tsun we want to attack our opponent in a very direct and savage manner . Other styles will contradict this objective by attempting non-direct tactics . If we combine them our objectives can become confused in the heat of the fight . We will be less effective .”

“The situation where you need to wrestle is when both opponents want to grab.”

“In Wing Chun if you throw two fast punches to someone's head they'll be knocked out. The first punch causes the brain to go to one side of the skull. If a quick second hit comes, the person is knocked out. If you withdraw the hand to give the second punch, then the brain can recover , but if you don't give this time then a knockout results.”

“This situation can happen to anyone. If you learn Wing Chun you can cope with it better than someone that doesn't know Wing Chun.”
