Considered the forerunner of Taiwan's "coming-of-age" genre, the film is a rich, original story written by LIN Tuan-Chiu. Centering on an accidental love triangle and a murder, the film crafts the two sisters' story with captivating intensity, along with several comic elements, beautiful songs, and a splendid local parade that aroused laughter and tears among local audiences. While focusing on female characters, as in The Husband's Secret (1960), the film also gives weight to a young woman's emotional growth as the conflict between sisters is finally resolved with Siok-Tshing's understanding and blessings.
