This lesson explains the change between Tan Sau and Wu Sao which is coordinated with lateral stepping. The next drill for front (Tan Sao) and back arms (Wu Sao) will show “two ways” this exchange will be done.
1) First change will be during Wu Sao slipping from under the front arm (Tan Sao) and the other exchange will be above the front arm.
2) Lastly, the following practice will give you great coordination between front and back arm through other Wing Chun techniques.
