Zaju was a form of Chinese opera which provided entertainment through a synthesis of recitations of prose and poetry, dance, singing, and mime, with a certain emphasis on comedy (or, happy endings). Although with diverse and earlier roots, zaju has particularly been associated with the time of the Yuan dynasty (1271–1368), and zaju remains important in terms of the historical study of the theater arts as well as Classical Chinese literature and poetry. Zaju is known to have been performed during the earlier Song (960–1279) and Jin (1115–1234) dynasties. The various particulars of the zaju multimedia performance were derived from many and diverse sources of musical, dance, poetry, and theater traditions.
