Xuyiji 續異記 "Continued records on extraordinary matters" is an early collection of stories compiled by an unknown author during the Southern and Northern Dynasties period 南北朝 (300~600). It is not recorded in ancient bibliographies but quoted in the encyclopaedias Chuxueji 初學記, Bai-Kong liutie 白孔六帖, Taiping guangji 太平廣記, Taiping yulan 太平御覽 and Shilei fu zhu 事類賦注.
The text includes stories about strange events from the Han 漢 (206 BCE-220 CE) to the Liang period 梁 (502-557). It is therefore quite probable that it was compiled in the late Southern Dynasties period.
The Republican writer Lu Xun 魯迅 (1811-1936) assembled fragments of the Xuyiji in his series Gu xiaoshuo gouchen 古小說鉤沉.
