Why do dances on the Korean Peninsula mostly appear in the form of simulated cranes?

The dance of the Korean Peninsula has a strong national flavor. The Korean nation regards the crane as its totem and is an agricultural nation that grows rice. Therefore, there are many dance images that imitate cranes in North Korean dances, such as the dancing postures of the arms made like the flying cranes, the movements made by the feet of the cranes raising their legs, etc. Korean national dance pursues a graceful and unrestrained charm that shows the crane.
