This is the fifth book in a new and important series on Chen style Taichi Chuan, demonstrating three different weapons sets for mastering Taichi, plus Push Hands (Tui Shou.) This fifth volume breaks down the Tai Chi Spear, the Tai Chi Halberd (Kuan Knife) and three different Tai Chi Pole sets: 13 Form Long Pole, Interactive Pole and Two-Section Pole. There is also a section on Push Hands, followed by a section called "Masters on Taichi" offering biographies of many masters and memorials of Master Chen Zhaopi and Chen Zhaokui. Every one of these classic routines shows the flavor and elegance of Chen Taichi. The descriptions are solid and make comments on what to emphasize and some written examples of application to combat. Chen Zhenglei (yes, it's no accident that his family name is that of the creators of Taichi) is a 19th generation descendant of the Chen family and an 11th generation direct line inheritor of Chen's Taichi. His Taichi studio in China is one of the most visited in the world. He has disciples in many countries. The entire series of books is a major contribution from Chen Zhenglei and Jack Yan. It is, at its core, a very detailed description of Taiji health movements, the two key routines of Old style and the two beautiful forms created by Chen Fa Ke of the New style, then a volume with four major weapons sets explained. The translation is literate and intelligent and very clear. Jack Yan resolves translation problems that have been stumbling blocks for a long time.
