Bored of her lonely celestial life at the heavenly palace, the Seventh Fairy Maiden is fascinated by the world of mortals. The fairy observes and is deeply moved by poor Dong Yong, who is obligated to perform hard labor for three years in the Fu household in return for a proper burial for his late father. When sympathy for him turns into earthly love, the Fairy Maiden descends to the mortal world. With the help of the God of Earth and the Shading-tree, a matchmaker, the fairy and Dong marry.
With the magical power of his wife and the six other fairies, Dong makes quick work of the tasks given him by the Fus. Ten bolts of immaculate brocade are miraculously produced overnight, a task that would otherwise require a hundred days to complete. The Jade Emperor learns of the fairy’s transgression a hundred days after she has come to the world of mortals. Infuriated, he orders the Fairy Maiden to return to the heavenly palace. Although already pregnant and deeply engrossed in the mortal world, the Seventh Fairy Maiden has to accede for Dong’s safety. Under the Shading-tree, the fairy reveals her identity and predicament, and the couple bid a sad farewell to each other.
The next year, Dong returns glorious from his success in the imperial examination, and the Fairy Maiden gives birth to a son. The Jade Emperor allows the Seventh Fairy Maiden to descend to the world once more to bring her son to his father and to meet her love for the last time. Though joined for a mere hundred days, their celestial love is revered forever among all beings.
