Wing Chun’s second form Chum Kiu means seeking bridge or bridging hand.  It is a way of closing the gap to make contact with your opponent coming in to Sticky Hand range.  The use of power is between hand and elbow.  It’s application of horizontal forward and back elbow combined with chain palm techniques to shut down your opponent’s hand and elbow attacks.  Chum Kiu combines the use of Bong Sau, Chum Sau, Tau Sau and Lan Sau with a strong stance and kicking techniques during attack and defence.  Practical application of these techniques require long term practice.
