This first video not only includes detailed analysis and explanation of the Wing Chun striking and blocking systems, but shows how many hand techniques have a corresponding leg technique. It's this parallel development between upper and lower body techniques which allows the Wing Chun practitioner to make the rapid progress associated with this art.
The chi sao or "sticky hand" training is shown and then Sifu Chow demonstrates the chi gerk or "sticky leg" techniques. This video also shows this art's grappling strategy and the empty hand defenses against knife and club.
