In its classical form (meaning passed from one genuine sifu to another without modification), Ving Tsun is regarded as an effective fighting system for three primary reasons:
First, CVT's primary pillar is that of its classical lineage with no deviation from its basic theories and principles. This obstinate clinging to classicism is the student's assurance that what he is learning is not significantly different from that which Ng Mui imparted to her first students. Some would argue that this obstinancy hinders any betterment of the system that otherwise would have occurred, but a system that ain't broke doesn't need fixing. Furthermore, CVT's effectiveness is heavily supported by its consistent production of effective fighters.
The second pillar upon which CVT stands is its introspective approach. Rather than stressing and capitalising on its own strengths, CVT uniquely focuses on its weaknesses in a constant effort to minimize them. One could also say that they system looks inward on itself, rather than externally to how it matches up to other styles. CVT has reached such a state of perfection that even a potential knock-
CVT's final and most practical pillar lies in its realism. The world of fighting is infinite, varied and unpredictable, as are the fighters themselves. Understanding this unpredictability of fighting has aided CVT in producing a system that stresses sensitivity over reaction -
The system supported by these three pillars is a complete one that is widely applicable to nearly every situation, whether it be bar fights, street fights, multiple opponents, slippery/uneven footing, grappling etc. The aim of CVT is to produce well-
Since a female created the system, it could be said that it works better for frail, small statured students. That is not totally the case, as larger students have an innate advantage in strength, and so have an edge over smaller students of an equal skill level. Ironically, though, smaller students tend to be more coordinated and more sensitive, and therefore pick up the system more quickly than a larger, especially bulkier, student. So, there is a balancing formular here: larger students have innate strength advantages but innate speed and coordination disadvantages when compared with smaller students.
Many other styles require constant training and daily exercise, also become obsolete when the fighter reaches a certain age because of their emphasis on external training. Approaching CVT Kung Fu in a a realistic fashion provides two primary benefits: low maintenance and long shelf-
Grandmaster Kan himself is over 60 years old, is still in top fighting condition and teaching CVT full time.
