The moon in Zhang Ailing's novel The Story of the Golden Lock is an image rather than a symbol. In the novel, the moon was depicted as a feminine and gentle image, representing the feelings and inner heart of women, but also hinting at some unspeakable secrets and pain. Through the image of the moon, Zhang Ailing expressed the complexity and variety of women's emotions, emphasizing the conflict and contradiction between women's inner heart and the outside world. This kind of image also allows the reader to have more imagination and association, which helps to explore the theme and emotions in the novel.
