Dr Wu was always surprising. Here was a small man, slightly stock, yet extremely nimble in his movements. He was well versed in many forms of Tai ji. So many in fact that it has been difficult to remember all that he has taught and kept up. He usually started every one with 24 form yang style and for warm up we would do either Liang gong, or the Mulan form. These were simple and average stretching, twisting and bending forms to prepare oneself. Once in a while we would do Silk reeling exercises. There were so many forms that he would teach, that he compiled two books, where his students would dissect the form and try to explain each of the movements. After editing and proofing, these were all compiled into two books. The book, let say, is decent enough in its explanation, but however since there are no pictures of the forms explained, then it is difficult at times to follow. One could use the book as a guide to remember the particular forms, but never to learn off bat. I remember the long summers where we would do the forms, and then afterwards all sit down, and break it down with pen and paper. It was tedious at times, for each one of us would have their own little variation of the form or own way of explaining it.
I still have my book, and when in doubt of a movement would refer back to it.
