There are two books with the title Kuoyizhi 括異志 "Inclusive reports about strange matters", one written by Zhang Shizheng 張師正 (born 1016), and another one by Lu Yinglong 魯應龍 (fl. 1247). Both lived during the Song period 宋 (960-1279). Lu Yinglong's book is commonly titled Xianchuang kuoyi zhi 閒窗括異志 "Inclusive records of strange matters from the leisure window" to discern it from the writing of Zhang. Both books are collections of fantastic stories.
Of Zhang Shizheng 張師正, courtesy name Buyi 不疑, not much is known, except for that he was a military commander (shuai 帥) of Chenzhou 辰州 during the Xining reign-period 熙寧 (1068-1077). He also wrote a book called Xianyou zalu 倦遊雜錄.
The encyclopaedia Wenxian tongkao 文獻通考 says that Zhang Shizheng, after successfully passing the state examination, wandered around for forty years in search for an office, but finally gave up and started compiling his 10-juan-long collection of tales of immortals. The book originally contained 250 chapters and a preface by Wei Tai 魏泰, but the foreword is lost, and the extant version comprises only 133 stories.
Zhang's Kuoyizhi is included in the series Sibu congkan xubian 四部叢刊續編 (in manuscript form) and Shuofu 說郛 (as an extract).
