The ten stories in this collection can be divided into three main categories: stories of the supernatural, stories with a political theme or adventure stories, and love stories. Supernatural events form the theme of most of the earliest stories. China had always been rich in mythology, and, after the introduction of Buddhism into the country, tales of ghosts and spirits became even more popular, so that during the Six Dynasties we find a great number of such tales. The earliest Tang story, An Ancient Mirror, is made up of a number of supernatural tales about an old bronze mirror. Ren the Fox Fairy, The Dragon King's Daughter and The Spendthrift and The Alchemist all belong to this category. They differ, however, from earlier stories of the same type in having more closely knit plots and more colourful detail, being, in fact, consummate works of art imbued with all the vitality of their age.
