Oxy, with all due respect, I have also recently learned the Li He Bua Fa movements from a classmate who learned the complete long form form from Liang Shouyu, the father of Helen Liang, one of the best water boxing practitioners. Do you realize that this form is a combo of Tai ji, ba gua and hsing i with elements of all integrated into one beautiful, effective form and fighting system. When I stated Yang did not have many up and down movements, maybe my comments were not clear. We of course do snake creeps down, etc, but when moving in internal or external, it is essential to be rooted for that moment of contact. As a great believer in good footwork being essential to great fighting prowess, Yang tai ji helped me connect the dots in my footwork, if you will, from my kung fu practice. In fact, the footwork drills we did for our moving push hands were directly relational to the patterned foot work I learned in Ying Jow Pai eagle claw, Wudan Nine birds family style, and southern white crane as well as the Tai Ji. As a bird mover (LOL! See my external styles), it has been a great help in understanding how foot movement and fa jing can be combined to generate great focused power for a little guy like myself, who is 5" 4" and 150 lbs against much bigger opponents. The foot movement of tai ji also taught me how to move concentrically as well as linearly, and provided insight to merge offensive/defensive into a flowing combined movement. As I stated, Li He Bua Fa is a combo and incorporates the best advantages of all three major internal styles. Again, just my opinion and personal experience.
