The word "Sipjin" derived from the thought of 10 longevity, which advocates there are ten creatures of long life, namely, sun, moon, mountain, water, stone, pine-tree, herb of eternal youth, tortoise, deer, and crane. They are 2 heavenly bodies, 3 natural resources, 2 plants and 3 animals, all giving human beings faith, hope and love. The poomsae Sipjin symbolizes those things.
The new techniques introduced in this poomsae are hwangso-makki [bull makki], son-badak[palm]-kodureo-makki, opeun-son-nal-jireugi, son-nal-arae-makki, bawi-milgi [rock pushing], son-nal-deung-momtong-hecho-makki, kodeo-olligi [lifting up], chettari-jireugi [fork-shape jireugi], son-nal-otkoreo-arae-makki, son-nal-deung-momtong-makki, which counts 10.
