Practitioners are trained to employ rapid punches, quick kicks, and a strong defense, as well as synchronized nimble stances and footwork. The aim is to make your opponent look foolish by using the law of angles to your advantage. Wing Chun has been proven time and time again to be effective for both self-defense and combat, with many styles including techniques from other systems. Although it was originally created as a system for use by police officers, today it is practiced by people from all walks of life who want to be able to defend themselves if needed. In conclusion, yes, Wing Chun is effective.
