The first book in English that presents both internal and external requirements of Chen Taijiquan Classic Old Frame First Road (Lao Jia Yi Lu) and Straight Sword routines. Over 1,300 photos by artist Martin von Haselberg offer unprecedented visual detail, revealing transitions, weight shifts and other aspects of the forms. In presenting these time tested forms together in one guide, authors Ren Guang-yi and Stephan Berwick reveal the similarities and differences between these influential martial routines. More so, the authors hope readers will appreciate the classsical partnership these enduring Taiji forms share.
