This is the DVD that got me started on the Wing Chun dummy. I have written about it earlier in the blog but here is a DVD clip about it. I like the way Michael Wong is ballistic on the dummy - absolute contrast to many other practitioners of the 116 movements. Note: it's a contrast, not the alternative.
The form is Pen Nam's form it has eagle claw moves in it, too, plus a re-juggling of many of moves that Yip Man's system has. If you know this form then you can add in Yip Man moves to spice it up. Yip Man's moves has more diverse kicks, (but not as diverse as Randy Williams / Austin Fong's system). There is some straight blasting in this form but not in Yip Man's form.
