Wing Chun training is dominated by partner exercises that repeat and hone all imaginable movement patterns involved in fighting off attackers from different fighting styles, all the way to unorthodox street fighters who do not comply with any rules or follow any particular patterns at all.
Depending on the experience of the trainee, the speed, intensity, and complexity of these exercises will increase and lead all the way to sparring and free-fighting. The goal of these exercises is to instil impulse-reflexes in the beginner through initially slow and repetitive movement sequences that can eventually be recalled on a purely subconscious level during stressful self-defence encounters.
Superficially viewed, the techniques do not appear particularly complicated. Although the applications are fast and powerful, the trainee must stay relaxed and avoid relying purely on brute strength. That’s why it is far more difficult to master these movements and techniques than it initially appears. This is also where the “internal” aspects of this art come to the fore.
