Chen style is the oldest form of Taijiquan from which all the major styles originated. Created at the end of the Ming dynasty, it is based upon a profound body of ancient knowledge that has influenced the Chinese way of thinking through the ages. It draws upon the principles of the Yijing (Book of Change), the Yin-Yang theory, and Daoist philosophy. Chen style Taijiquan combines the study of traditional Chinese wu shu, movement science, and the Chinese medical theory of "jingluo" (energy channels), "daoyin" (leading and guiding energy), and "tu-na" (breathing methods), resulting in a comprehensive system of self-defence and a valuable health exercise. This text guides the reader through the historical development of the system, its philosophical roots, and through the intricacies of the various training methods of this unique form of Chinese boxing. Descriptions of the Silk-Reeling Exercise, Laojia Yi Lu, Laojia Paocui, Fajin, Qinna, Push Hands, and Taijiquan weapons are all featured. Legendary exploits of the Chen family are included to inspire today's practitioners.
