The Chil Sung forms were created in 1952 by Hwang Kee, founder of the Moo Duk Kwan in Korea. This series of seven hyung is designed to be an individuals path toward balancing Weh Gung (physical) and Neh Gung (spiritual). This balancing concept is known as Chun Gul Ryu, which translates into Middle School. Students of these hyungs begin their practice of Chun Gul Ryu by making a distinct separation between the slow and the fast portions of these hyungs. One can also see the influence of Hwang Kee's training in Yang Style Tai Chi in these hyungs.
The words Chil Sung translate to "Seven Star" and refer to the seven stars of Ursa Major (the big dipper). This constellation is used to find Polaris, the North Star, in the constellation Ursa Minor (the little dipper). Just as the North Star is used for navigation, the motivation of the Chil Sung Hyungs is to guide the practitioner to become a better martial artist.
