Many doctors developed qigong exercises which were modeled after animal movements to maintain health and cure sickness. A typical, well-known set of such exercises is Five Animal Sports (Wu Qin Xi,), created by Dr. Jun Qing and later modified and publicized by the well-known medical qigong doctor, Hua Tuo) during the Chinese Three Kingdoms Period (A.D. 221-265). Another famous set, based on similar principles, is called the Eight Pieces of Brocade (Ba Duan Jin ), and was created by Marshal Yue Fei during the Chinese Southern Song Dynasty (A.D. 1127-1280). Interestingly enough, Yue Fei was a soldier rather than a doctor.
