Chuseok is a three-day celebration in South Korea. Normally falling around a full moon between September and October, this harvest festival involves honoring one's ancestors and sharing feasts with friends and family. People will generally return to ancestral towns in order to pay their respects by maintaining gravesites and laying out special food offerings. "Living participants can enjoy songpyeon, a sticky rice cake shaped like a half-moon, made with sweet fillings and steamed over fragrant pine needles. Older merrymakers can enjoy a liquor made from fresh rice," Smith said.
