This slender and concise classic has never been surpassed. In just a few pages, Chen Wei-Ming outlines the key points regarding T'ai Chi application, particularly explaining the use of the art in clear language with excellent examples (although other areas are covered as well). The chapter on Free-Fighting alone is worth the price of the book. In an era where knowledge of T'ai Chi application as a martial art has almost disappeared, this book is not only the best study guide (to be read and reread) but also a great "test" for steering clear of bogus teachers. Simply put, if a teacher of T'ai Chi cannot understand or demonstrate the concepts within this book, he or she should close up shop at once. Finally, this book was translated largely by Ben Lo, world renowned for his extremely high level of skill in push hands and application. Every true T'ai Chi practitioner will treasure this classic.
