"Songpyeon" is also significant because of the meaning contained in its shape. "Songpyeon's" rice skin itself resembles the shape of a full moon, but once it wraps the stuffing, its shape resembles the half-moon. Since the Three Kingdoms era in Korean history, a Korean legend stated that these two shapes ruled the destinies of the two greatest rival kingdoms, Baekje and Silla. During the era of King Uija of Baekje, an encrypted phrase, "Baekje is full-moon and Silla is half-moon" was found on a turtle's back and it predicted the fall of the Baekje and the rise of the Silla. The prophecy came true when Silla defeated Baekje. Ever since Koreans have believed a half-moon shape is an indicator of a bright future or victory. Therefore, during "Chuseok", families gather together and eat half-moon-shaped "Songpyeon" under the full moon, wishing for a brighter future.
