“Su Wol Kyung Hwa (水月鏡花)” is a four-character idiom that refers to the moonlight reflected on the water and a flower in the mirror. This denotes a poetic, intangible atmosphere, one that is visible but cannot be touched, and beautiful beyond description.

Heo Nan Seol Heon was a prominent Korean poetess of the mid-Joseon dynasty. Born in a time when women were not recognized for their talent, she lived a tragic life, wasting away from neglect by her husband, the fall from grace of her family, and the death of her two children in infancy. She predicted her own death with a poem. Springing up from the harsh realities of her life, her poetry is a clear expression of her genius. While not appreciated during her time, it later gained the attention it deserved, even receiving high praise in China. Su Wol Kyung Hwa is a representation of two of her many poems, Gamu and Mongyu-Gwangsangsan, to reveal the hidden treasure of her poetry as well as her life that was both sad and beautiful.
