Kwok is credited as one of the key people who systemized Practical Wing Chun study into a modern-day training program. He promotes the concepts of martial skills and teaching skills as two different skill sets, and that martial arts teachers' training should include teachers education such as curriculum design and analysis, motor learning, and teaching methods. In addition, he emphasizes the need to balance physical training of technique with philosophical training of the mind "like Yin and Yang...complementing and supplementing each other",[1] believing that a strong sense of culture and humility - what he calls "martial virtue"[2] - are critical to the study of martial arts and the improvement of the martial artist.[17]
