In Treasure Island, Sojung Jun who observed and researched on individuals working between art and artisanship and between art and life in recent years tells us the story of a Haenyeo(Korean female free diver), whose work mediates between man and nature. As Korean traditional singer Kim Yulhee sings a song of Jeju grandmothers and mothers in her adorable voice, clips of Haenyeos of the Saekdal beach, Jeju, doing “Muljil,” or diving into the sea to gather seaweed, abalone, etc. are played in the background. Keeping the ancient way of living, or collecting and hunting, Haenyeos should both fight against and adapt to nature. In this way, they know how to live to the rhythm and cycle of nature.
