|By David Chow and Richard Spangler. #103. 7 X 10, 240 pages, paperback. ISBN 0-86568-011-6. Revealed for the first time in English are some of kung-fu's most outstanding secrets-the reality behind some of the enigmas. From original sources in China, Chow and Spangler describe feats which most Westerners consider impossible, including: how to walk up the side of the wall; how to beat an enemy with the flick of a finger, and the delayed death-producing Red Sand Palm.
