Query: Simply outstanding

Everything in this DVD is wonderful--Helen Liang's technique is simply top-notch. My only critique is that for those unfamiliar with the snake style, the DVD lacks a step-by-step breakdown of how to execute each phase of the form. Some of the techniques and postures are rather complicated, and may require extra time and patience in order to be successfully digested. Don't let that be a put-off for getting this video, however; this program is really a delight once you have put in the time and figured out how to dance the dance.
