The creation of the Eagle Claw method is normally attributed to General Yue Fei (1103–1141) who lived at a time of conflict between the Southern Song Dynasty and the Jurchen tribes of the Jin dynasty. Despite being literate, young Yue Fei chose the military path because there had never been any tradition of full-fledged Confucian civil service in his family history. However, the Yue family was much too poor to afford military lessons for their son, so the boy's maternal grandfather Yao Dewang hired Chen Guang (陈广) to teach the eleven-year-old how to wield the Chinese spear. Then a local knight errant named Zhou Tong (周同) was brought in to continue Yue's military training in archery after he had quickly mastered the spear by the age of thirteen.
