Wing Chun is a simple system,  in many Shaolin Arts there are showy and superfluous techniques put into forms because they are appealing to the eye. Wing Chun was created without these, instead it has only the most vital and most effective techniques!
Wing Chun is taught in grades, a system comprising of 12 student levels and 9 additional Technician and Practitioner levels. Ranks and grades are used  to show what aspects of WC you are learning, not as a contest or status symbol.
