Moi Fah: The Plumb Flower Fist is one of the easiest books on forms to understand. The form itself is clearly photographed, and the author does a great job of explaining what's going on. Applications of techniques are spread throughout the form. Also of value are the warm-ups at the beggining of the book, as well as the explainations of body movements in the back. This is a good book to learn this particular form, and gave me my first exposer to Chinese long boxing. The only reason I didn't give it five stars is because of it's limited scope.
A very good demonstration of the Moi Fah form. Unlike some of the books that came out of Hong Kong in the early 1980's, Kwon Wing Lam includes the applications of the techniques. Also includes Chinese and English table for the techniques of the set, and well written sections on the history of Northern Shaolin (or Sil Lum) and kung fu in general.
