Ji Yun (Chinese: 紀昀; pinyin: Jǐ Yún; 1724–1805), also known as Ji Xiaolan (Chinese: 紀曉嵐; pinyin: Jǐ Xiǎolán) or Ji Chunfan (Chinese: 紀春帆; pinyin: Jǐ Chūnfān) was a Chinese philosopher, politician, and writer. He was an influential scholar of Qing dynasty China and many anecdotes have been recorded about him. Ji Yun left behind a book entitled Notes of the Thatched Abode of Close Observations (閱微草堂筆記; The Shadow Book of Ji Yun, Empress Wu Books, 2021), and another book named Wenda Gong Yiji (紀文達公遺集; Collected Works of Lord Wenda, i.e. Ji Xiaolan), which was edited by later generations. He was often mentioned with Yuan Mei as the "Nan Yuan Bei Ji" (Chinese: 南袁北紀; lit. 'Yuan of the south and Ji of the north').
