Ganzeyao 甘澤謠 "Tales of sweet enrichment" is a collection of stories compiled by the Tang period 唐 (618-907) scholar Yuan Jiao 袁郊, courtesy name Yuan Zigan 袁子乾. He came from Caizhou 蔡州 (modern Queshan 確山, Henan) or from Chenjun 陳郡, lived during the reign of Emperor Xuanzong 唐宣宗 (r. 712-755) and served as director (langzhong 郎中) in the Ministry of Sacrifices (cibu 祠部), academician (xueshi 學士) in the Hanlin Academy 翰林院 and regional inspector (cishi 刺史) of Guozhou 虢州. Yuan Xiao was befriended with Wen Tingyun 溫庭筠. The book was finished in 868 and includes nine stories of extraordinary events, immortals, Buddhists and the miraculous skills of wandering knights. The language is very refined and elegant, which contributed to the wide circulation of the text. There is a preface written by the Ming period 明 (1368-1644) scholar Yang Yi 楊儀. One chapter called Nie Yin niang 聶隱娘 is quoted in the encyclopedia Taiping guangji 太平廣記, but not to be found in the received version, which is otherwise likely to be preserved complete. It might therefore be that this chapter is derived from Pei Xing's 裴鉶 book Chuanqi 傳奇.
The Ganzeyao is included in the reprint series Jindai mishu 津逮秘書, Xuejin taoyuan 學津討源, Siku quanshu 四庫全書, and Congshu jicheng 叢書集成. In 1978 the Shanghai guji press 上海古籍出版社 published Wang Pijiang's 汪辟疆 book Tangren xiaoshuo 唐人小說, which includes the whole text of the Ganzeyao.
