Pyongwon means a plain or a vast field of land. It is the source of life for all creatures and place from which all creatures gain sustenance. Pyongwon is based on the idea of peace and struggle resulted from the principles of origin and use. The Choon-bi sogi requires a concentration of force in the lower abdomen, the source of all strength, much like the land is the source of strength for all life.
The line of movements symbolizes the origin and transformation of the plain.
There are 25 movements in Poomsae Pyongwon. This form is for the 4th Dan.
