Query: Wothwhile tai Chi Book

This is not a fancy tai chi book with lots of color pictures of the form, but it does have a lot of good information. The tai chi form used in the book is the Yang Short Form. Each step of the form is shown in a black and white pencil sketch with a good description of each move. Of value to me was the accompanying diagram that shows foot placement and relative weight that is placed on each foot as well as text that tells how to properly breath for each movement.The latter part of the book describes the importance and history of each move that gives good background to the form. The last section includes the series of all the form element line drawings in sequence to give you a better idea of the flow of the form.
