Ballet "The promise that day" adapting a scene of the feature film "Wholmi Islet" tells the truth that the noblest feats of the youth are the ones performed in defending the country, through the performance by the dancers who combine the beautiful rhythm of the Korean dance with high ballet skill.

Another ballet work "This Country Is So Good", which personifies swallows flying over bumper wheat and barley fields, vividly represents a new look of a socialist farm village by organically mixing the elegant and delicate Korean dance with ballet skill.
