excellent reference . Like other reviewers, I agree that a book is no substitute for instruction by a teacher. Nevertheless, this comes as close (for the Yang style short form) as anything I've found. Even if you have no interest in the martial aspects of taiji, having the potential applications of the form enriches practice. I found the illustrations clear. I own a half dozen or so books on taiji, and this is the only one I regularly consult

Ex Output:
POS

I officially hate this book! . I, also, must second Mark Twain. This book is a waste of time! Why do teachers make us read it when we should be reading Tolkien, GK Chesterton, CS Lewis, and the like? Agh. Then, that could just be my wacky taste in novels... But this was bad. Oh my gosh!!! The descriptions were ALWAYS needlessly long, the conversations ALWAYS needlessly long, the... blah, blah, blah, blah. That's what the whole thing was. Blah. The whole plot could have been totally condensed to a hecka short 200 pg novel and it would have been a million times better! Maybe even good! And I like long books! This book is terrible. Listen to the warning of a fellow voracious reader and do not waste your time!

Ex Output:
NEG

When Mr. Pignati dies, John and Lorraine feel the only way they can relieve their guilt is to write down what happened in their time together. This is their story
