The style spread as Chin Woo opened sister schools in other provinces. His student Liu Cheng You later taught Chen Zizheng who was invited to teach the style in the prestigious Chin Woo Athletic Association during the Republican era. During the Qing dynasty, the military instructor Liu Shi Jun became known as the modern progenitor of Eagle Claw and taught many students. Thus, the style took on long range strikes and aerial jumps. It was passed down until the Ming dynasty. Popular legends states that he learned martial arts from a Shaolin Monk named Zhou Tong and later created Eagle Claw to help his armies combat the invading armies of the Jin dynasty.
The style is normally attributed to the famous patriotic Song dynasty General Yue Fei. Eagle Claw ( Chinese: 鷹爪派 pinyin: yīng zhǎo pài eagle claw school) is a style of Chinese martial arts known for its gripping techniques, system of joint locks, takedowns, and pressure point strikes, which is representative of Chinese grappling known as Chin Na.
