≡Imperial Renaissance Fighting Systems/IRFS≡ is a training system of ancient martial science and psychology, geared for the modern man. The knowledge and foundation are extracted from the Beijing Imperial Renaissance arts of Yin Style Baguazhang, Cheng Baguazhang, Shaolin, Bajiquan, and Gongfu Jia Chen Tai Chi Chuan. Our organization takes an academic journey through factual military history, however, adapted for the 21st century and modern lifestyles. Dong Haichuan’s historical system is unlike anything in the kungfu cinemas, nor similar to the mainstream interpretation popular in modern culture. Popular Baguazhang instruction today is inspired by the popular 1920s novel ‘Tong Lin Chuan’, which presents the founder of Baguazhang’s martial arts and life- in a fantastic/ inaccurate way. The “internal martial arts” with the branding of BAGUA, XINGYI, TAIJI, branched directly from folk tradition in the Peking Opera at the fall of Qing Dynasty (1900) and the Republic of China reforms. The 1928 reform and legends presented in ‘Tong Lin Chuan’ altered the original intent and curriculum, and now Baguazhang has shifted into purely sports and cultural philosophy. The benefits of modernization of Internal Martial Arts unfortunately impacts the original systems negatively. Historical research by numerous Chinese scholars reveals- there is no evidence the ancient masters earned their reputation by the context of training, in today’s kungfu culture. By the 20th century, Internal Martial Arts were reimagined by reformers and teachers as ways to preserve Chinese culture, or to strengthen the Chinese nation against foreign oppression… Feudal Yin and Cheng Style Baguazhang has roots in the Imperial Court during the mid-1800s at Chongwenmen, Beijing, where Dong Haichuan served as Imperial tax collector and Bodyguard for Prince Su (Shan Hao). The real person named Dong Haichuan (1797 – 1882) was born in the Jiaqing period of Qing Dynasty, formerly known as Dong Mingkui, and was born in Zhujiawu Village, Wen’an County, Hebei Province. The Dong family lived in Hongdong County in Shanxi Province. The ancestors of Dong Haichuan were the generals of the Yuan Dynasty. They served as the deputy marshal of the general of Long Huwei. Dong’s ancestors moved to the city of Hebei in the early years of the Ming Dynasty. The descendants of their descendants were military commanders for five consecutive generations. According to Wen’an Wenshi data and Xiongxian County records, many people in the Dong Haichuan family are military commanders and feudal Shaolin professionals. Dong Haichuan synthesized Baguazhang, a sophisticated martial art, adapted to each individual by his own experience while retaining the essential principals and structure. The Senior Disciple of Dong Haichuan, Yin Fu, adapted principals of the art to his own martial background (Qing Military/Intelligence), developing Yin Style Baguazhang. The Yin style of Baguazhang popularized the “OX-Tongue” palm- however, the context of its application is primarily influenced by the Peking Opera tradition and ‘Tong Lin Chuan’ novel in modern times. The separation of Yin and Cheng styles on a palm shape is a misunderstanding. Modern Baguazhang interpretation has undergone two waves of sports modifications since 1928. Historical evidence reveals Yin Fu utilized “Tiger Claw/ Dragon shape” as well, and the “Ox” palm is a mislabeling of the “Willow-leaf” palm characterized by the willow leaf saber of Imperial Guards in 1800s. Yin Fu’s method emphasizes Hard Palm training, characterized by the military/ martial training requirements of Imperial Officers & cavalry. The Yin Style of Bagua is an integrated part of modern martial arts branching from “The Fairbairn Method” of William E. Fairbairn. One of William E. Fairbairn’s students was Ian Fleming who went on to write the James Bond series of books. Yin Style Baguazhang contains Shaolin empty-hand and armed strategy of various military divisions- modern firearms, pudao, spear, military saber, zhanmadao, and clandestine weapons. Yin Fu is a First Rank Imperial Guardsman of Emperor Guang Xu and the Empress Dowager. In the early 20th century, his disciple, Cui Zhendong /Retainers of the Imperial Court, instructed Baguazhang to William E. Fairbairn. Fairbairn made dedication in his book All In Fighting (1942) to Cui calling him a man of “terrifying prowess.” Cheng Ting Hua is the other top student of Dong Haichuan- a candidate for the royal bodyguards of Empress Cixi. The Cheng style of Baguazhang popularized the Dragon Claw Palm, characterized by fluid (weaving/interlinking) body (serpent/dragon-like) movements with complex coiling and spiraling. The style is more dynamic and smooth externally, with intricate footwork patterns, Manchurian wrestling/ restraint methods. Cheng Ting Hua’s original Baguazhang is more practical than the modern “mud-stepping” interpretation which is popularized post 1928. As an example, folk Cheng Baguazhang uses an “Oversized Saber & deerhorn knives” which context originated from novels in the early 20th century. The feudal Cheng Bagua system contains numerous historical weapons- though dominant in the Pudao/Guandao style of arms. Cheng Tinghua was very much the People’s Champion. Cheng was a high level and open martial artist who believed in evolving martial art techniques and theories, sharing knowledge with martial artists of different branches.
