Ying Zhao Fan Zi Men or "Eagle Claw" as it is widely known, is a system of more than 800 years old. In fact it is a combination of Yue Shi San Shou and Fan Zi .
Legend states that general Yue Fei (1103 - 1142 b.C.) of the Song dynasty, developed a a series of very effective fighting techniques to teach his soldiers, thus creating the "108 hands" and a system that was named Yue Shi San Shou, meaning "Yue Fei fighting techniques" . After his sudden death, his faithful soldiers went all over China and tought his system. There isn't any reliable information about the historical continuity of the system, but years later, during the Ming Dynasty (1368-1664), in general's Qi Ji Guang book about war strategy and WuShu, there is mentioned the "Grab of the Eagle King" . This mention in a way proves that the system was preserved and well known at that period of time. In this same book, Qi Ji Guang mentions Ba Shan Fan (another name for Fan Zi) as one of the most effective fighting systems of the Ming Dynasty.
There isn't any historical proof about when the combination of the two systems took place. It is highly probable that the monk Li Quan , a master of Fan Zi who lived during the ends of the Ming Dynasty, saw Yue Shi San Shou and was so impressed that he decided to work on both systems and combine them. Other sources mention that Li Quan lived many years before Ming Dynasty and was the one who taught general Yue Fei the nine basic techniques (3 up, 4 in the middle, and 2 down). Yue Fei then developed Yue Shi San Shou based on those nine techniques. However there is no written evidence for either of these theories.
A certain fact is the appearance of a very important figure , in the end of Qing's dynasty (1644-1711) Liu Shi Jun , who sets start on a new period. Since that time , the system is being taught in public, so today almost everything is known about its history.
Liu Shi Jun was taught the system from two monks, Gao Ji and Fa Cheng. In his turn he passed the system to his grandson, Liu Cheng You . Cheng You taught his third son, Liu Qi Wen and his nephew, Chen Zi Zheng . Chen Zi Zheng is known as the "Eagle King" . He gathered Yue Shi San Shou tecniques and Fan Zi techniques, creating thus two new taolu (forms) which are called Shi Lu Xing Quan (10 ways of moving punch) and Wu Shi Lu Lian Quan (50 ways of continuous punch) . These exceptional forms possess all the secrets of the "108 hands" , Yue Fei's system. Chen Zi Zheng 's personal student was master Guo Chen Yao , father of our family's master Guo Xian He .
