Originally there were only 3 old palms. Over several generations of practitioners, 8 palm methods were compiled. From these 8 palm methods, 64 palm methods were derived. Thus we call the original 8 palm methods "old 8 palms" or "8 large palms". These palm methods are the foundation of Ba Gua Zhang fighting methods. Due to diversified schools and lineages, there are many variations of the 8 palm methods. In this book, the 8 palm methods from Cheng Ting Hua style are introduced. For anyone that is interested in Ba Gua Zhang fighting methods, the contents of this book are essential to know. The 8 palm methods may derive into more fighting methods. They are like the 8 diagrams in the book of change or Yi Jing. Thus they gained the name of Ba Gua Zhang(Eight Diagrams Palm).
