Gyobang(교방) refers to Kisaeng's place where they lived, practiced singing or dancing, and performed, so Gyobangchum(교방춤) literally means Kisaeng's dance.
There are many kinds of Gyobangchum. Among them, this video is showing us Yeongnam(Gyeongsang-do Province) Gyobangchum. How beautiful and elegant the movements are!!! I hope you like it~
