By Stuart A. Olson. #287. 7 X 10, 176 pages, paperback. ISBN #1-892515-15-6. This book presents for the first time in one comprehensive volume a complete record of Yang style Tai Chi 'push hands' or 'sensing hands' techniques. Although most Tai Chi practitioners are currently familiar with three or four of the main push hands techniques, there are a variety of other 'hidden' sensing hands methods that previously have not been presented to the public.
