This is a topic of some heated conjecture. It seems everyone has a strong opinion on this. As far as we are concerned this just refers to the 2 different strains of Wing Chun Systems in the Yip man Lineage. Perhaps two halves of a greater whole? Most notably, from a technical standpoint, Traditional Wing Chun has a greater focus on active footwork, whereas Modified Wing Chun will tend to lean and pivot rather than stepping out. There are a few differences, but really, it’s all Wing Chun. There are many different strains of Wing Chun, let us not get bogged down with labels. At Eastern Kung Fu we come from the Traditional Wing Chun Line.
