Excerpted from "How Effective is Wing Chun":
A famous “fight,” which is still discussed today after years of bickering, once took place between William Cheung and a student from another lineage. The choppy video of this event is held up as “proof” of any number of spurious claims. “Cheung can’t fight,” is one. “Cheung got his *** kicked,” is another. “Wing Chun is not street effective,” some conclude. “Wing Chun people can’t grapple,” some argue. Of these, only the latter has even a little validity, though a single scuffle proves very little about the skills of those involved. Anyone, after all, can screw up or have a bad day, and nobody is alert to danger at all times (though they should be).
An objective look at the video (which both sides claim has been edited to the benefit of the other) shows us that A) Cheung protects his center as heÂ’s been taught to do; B) the aggressor mounts him and throws wild blow after wild blow; C) Every time Cheung tries to throw a leg up over his opponent, he slides across the gymnasium floor, providing the viewer with a valuable lesson on the ways in which terrain can screw up our best laid plans.
When the “fight” was over, neither party was injured. So what does this tell us? It tells us almost nothing. From it we learn nothing about Wing Chun as a system (other than the need for cross-training in grappling to cover what is arguably a blind spot in Wing Chun, though most schools do train in “anti-grappling”). We learn relatively little about the two participants, other than that they didn’t hurt each other. We learn, simply, that politics can leave a black eye on a style that no amount of punching can inflict.
I believe there is a right way and a wrong way to perform certain techniques, even though some lineages teach the variations as acceptable. As always, reality is the deciding factor. In my school, for example, we are taught to distribute our weight evenly on both feet for optimum balance and mobility. Anyone who tells you, therefore, that “Wing Chun is ineffective because the weight is placed primarily on the rear leg” is in error – though that error may be the product of poor teaching in a lineage or school imparting improper structure.
When we discuss the efficacy of Wing Chun, then, we must acknowledge that many schools and lineages teach different things. Where there is conflict, we must be biased towards those techniques and principles that offer the best REALISTIC results. All else is not “proof of Wing Chun’s ineffectiveness” – it is proof of poor teaching (or poor learning). The final arbiter is reality, not claims or stories or family trees. Wherever a better alternative exists in the pantheon of Wing Chun masters, it is that alternative that represents “true Wing Chun.”
