An impressive work opening the doors to a rare system of the Chinese fighting arts. In this book you will learn about the history of the Fukienese White Crane style and specifically about one of its rarest branches wich is Fei He Chuan (Flying Crane Fist). You will also find (among other things) detailed pictures of the complete basic form and many self-defense applications and training tips. But the main treasure in this book is in the clear explanation of the main fighting principles and fundamental concepts and theories in applied martial arts. No matter what art you practice, this is one of those book you will find yourself going back to over and over again.
