Over all, this is a very good intructional book. It has a very detail text explaination and plantiful of pictures to guide you from one movement to another movement. The only thing that I don't understand is: how come there are no instructions on breathing sequences for each movement? I understand that the integration of inhaling and exhaling with each movement is very important for Tai Chi, why is this book not teaching it? I hope Master Huang will publish a booklet of breathing sequences for these set of Wu Style Tai Chi forms.
