Yupu zaji 寓圃雜記 "Miscellaneous notes from the Garden of Abiding [Thoughts]" was written by Wang Qi 王琦 (fl. 1453) of the Ming dynasty 明 (1368-1644). Wang Qi, courtesy name Yuanyu 元禹, style Mengsu Daoren 夢蘇道人, was a native of Changzhou 長洲 (modern-day Suzhou 蘇州, Jiangsu). The exact years of his birth and death are unknown.
His book is a "brush-notes"-style work (biji 筆記) that records events and anecdotes from both official and popular circles, spanning from the Hongwu era 洪武 (1368-1398) to the Zhengtong reign-period 正統 (1436-1449). The sections concerning the region of Wu 吳 (around Suzhou 蘇州, Jiangsu) are especially detailed in their accounts of historical anecdotes. The entire work does not engage in textual criticism or evidential scholarship. Instead, it mainly consists of fictionalised narratives and historical anecdotes.
Therefore, Jiao Hong's 焦竑 (1540-1620) book catalogue Guoshi jingji zhi 國史經籍志 (listing the book as with 1 juan length), the Qianqingtang shumu 千頃堂書目, the bibliographical chapter of the official dynastic history Mingshi 明史, and the Siku quanshu zongmu tiyao 四庫全書總目提要 classify Wang's book as fiction (xiaoshuojia lei 小說家類).
However, much of the material borrows from trivial pre-existing stories and even wording, which makes it more difficult to use for textual verification or scholarly research.
The text with a transmitted arrangement of 10 juan is included in the series Xuanlantang congshu 玄覽堂叢書, and in extracts of 2 juan in the Jilu huibian 紀錄彙編 and Congshu jicheng chubian 叢書集成初編, and with only 1 fascicle in the Jinsheng yuzhen ji 金聲玉振集, Gujin mingxian huiyu 古今名賢彙語, Xu shuofu 續說郛 and Wuchao xiaoshuo 五朝小說.
