Eagle Claw (Chinese: 鷹爪派; pinyin: yīng zhǎo pài) is known for its gripping, joint locks, takedowns, and pressure point strikes, which is representative of Chinese grappling known as Chin Na. It is normally attributed to the famous Song Dynasty General Yue Fei (1103–1141). Legend states he learned martial arts from Zhou Tong, a Shaolin Monk, and later created Eagle Claw to help his armies combat the invading Jin Dynasty. During the Ming Dynasty the monk Lai Chin combined it with the boxing form Fanzi. The style took on long range strikes and aerial jumps. During the Qing Dynasty, the military instructor Liu Shi Jun became known as the modern progenitor of Eagle Claw and taught many students. 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. The style spread as Chin Woo opened sister schools in other provinces. Today, it is practiced around the world.
