The Guang yi ji (simplified Chinese: 广异记; traditional Chinese: 廣異記; pinyin: Guǎng Yì Jì), translated into English as the Great Book of Marvels,^[4] is a collection of Classical Chinese stories written in the eighth century by Tang dynasty author Dai Fu [zh]. Although the original manuscript is now lost, over three hundred stories are preserved in various texts from the late Tang and early Song dynasties.

Dai Fu (戴孚), who graduated as a jinshi in 757, wrote most of the entries in the Guang yi ji while he was working as a bureaucrat in Zhejiang in the 760s and 770s.^[5][6] Many of the stories are set in this time and place; Dai claimed to have either witnessed the recorded events himself or heard about them from other local officials.^[4] Some stories appear in earlier texts and may have been transcribed by Dai into his work.^[7]

Like most other short story collections from the Tang dynasty,^[8] the original manuscript purportedly comprising twenty scrolls and around a hundred thousand characters is now lost.^[9] However, some three hundred stories are preserved in the Taiping guangji,^[10] while a few others can be found in reference books from the late Tang and early Song dynasties,^[11] such as the Suishi guangji (歲時廣記) or the Taiping yulan.^[9]

The undated preface for the Guang yi ji was written by Gu Kuang,^[12] who had become a jinshi at the same time as Dai. Gu received the stories from Dai's two sons after his death at the end of the eighth century.^[9] In the preface, Gu briefly recounts the history of what he calls zhiguai or "strange tales" and suggests that Dai's supernatural stories would be regarded by contemporary readers as being of the same genre as historical records.^[2][a] Gu's preface survives in a sixteenth-century reprint of the tenth-century anthology Wenyuan yinghua, while variants of it can be found it at least a couple of later texts.^[14]
