SIPJIN - Was derived from the concept of 10 longevity which states that there are 10 creatures of long life: sun, moon, mountain, water, stone, pine tree, herb of eternal youth, tortoise, deer and crane. There are 2 heavenly bodies, 3 natural objects, 2 plants, and 3 animals, all giving to human beings faith, hope and love. The poomsae Sipjin symbolizes these things. The Chinese letter meaning ten is the form of the poomsae line, which signifies an infinite numbering of the decimal system and ceaseless development.
