The story of two lovers, Shuang Chien and Su Little Lady (Su Hsiao-ch'ing) was one of the most popular in China during the Southern Sung and Yuan dynasties, and survives in many poems and numerous allusions in various kinds of literature. The main early works embodying it (a tsuan-tz'u ballad, a yuan-pên play and a chu-jung-tiao ballad) have not, however, survived and this article attempts to piece together its details from the allusions and references in early literature and also, more tentatively, from the Ming and Ch'ing dynasty works concerning the tale.
