No one has done more over recent years to promote the study of the genre of Chinese literature known as pien-wen in the English-speaking world than Victor Mair of the University of Pennsylvania. Since the discovery of this type of T'ang popular tale among the Tun-huang manuscripts which were recovered at the start of this century, a considerable body of scholarship has been produced to explain its origins and affiliations. The results of all this academic effort are now surveyed in three volumes by Mair: one a selection of translations, one a survey of comparable phenomena outside China, and one (dealt with here) addressed to the main problems raised by the Chinese materials.
