Bong sao video
Info about "Bong sao video"
The Bong Sao (wing arm) is a Wing Chun Kung Fu blocking technique. It uses the little finger side of the arm to deflect your opponents strike with the palm facing the opponent and the fingers held relaxed in line with the center of the body. The elbow forms a 135 degree angle with the wrist lower than the elbow and the elbow higher than the shoulder (depending on the height of your opponent). The thumb is held loose in this block which ensures that the strength is on the little finger side of the arm to correctly deflect the incoming strike.
