Wing chun looks so legit in demo. And the good fighters in the past use wing chun. Like bruce lee, wong shun leung. They have crazy speed with their hand and highly sensitive arms (trapping). Extremely fast straight blast etc etc.(search on youtube for example samuel kwok). But why we never see it against real kickboxer/boxer/mma fighters? If it doesnt work. Why guys bruce lee,ip man, wong shun leung be the best with wing chun? And if you look the history of wong shun leung. He beat all style with his wing chun.
