This is one of my favorite books in my martial arts library. It contains a wealth of information, most of which are forms, on the major internal style of Hising-I chuan (or else known as Xingyi quan). It also shows applications in combat, with step-by-step instructions for everything. Its real treasures, though, are the stories about the masters, and the advice the masters themselves give. Not to mention the really cool pictures of a few of them doing the techniques themselves! Awesome book.
