Ji Jihun actually didn't like his name very much.
Ji's father and Ji's mother were fans of Song poetry. It is said that before giving birth, the couple happened to read the phrase "There is no way out of ecstasy" by Li Qingzhao. Ji's mother felt a sharp pain in her abdomen and her amniotic fluid broke.
So Ji's father and mother, who had a daughter late in life, were so overwhelmed with joy that they simply named their baby girl this name.
