Jeroen applies Butterfly Palms to counter Max' double grips

Grandmaster Wong makes the attack situaion more difficult. Now he applies a double grip on an opponent's arm instead of a single grip on his elbow as in the previous series. If the opponent is slow, he pulls him onto the ground. How would you counter this double-grip chin-na technique. Again the course participants come out with excellent counters. At the end Grandmaster Wong demonstrates using Butterfly Palms to counter the double-grip chin-na attack.
