There are 24 patterns in the official ITF syllabus; this is symbolic of the 24 hours in a day. One additional pattern, Ko-Dang (or Go-Dang), was retired/replaced by Juche in 1986 by General Choi Hong Hi. The names of these patterns typically refer either to events in Korean history or to important people in Korean history. Elements of the patterns may also be historical references, such as the number of moves, the diagram, the way the pattern ends, and so on.
