Ní Huìdǐng 倪會鼎 (1620–1706), son of the Míng martyr 倪元璐 (1593–1644) of Shàngyú 上虞. After his father’s suicide on the fall of Běijīng in Chóngzhēn jiǎshēn / 1644, Huìdǐng preserved the corrected proofs of his father’s collected works and remained as a Míng loyalist yímín through the early Qīng. His own preface to the Ní Wénzhēn jí (KR4e0240) — the third of the four prefatory matter pieces in the WYG — recounts the loss of most of the manuscript in the Chóngzhēn end-times catastrophe and reduces the survival to ‘three or four parts in ten’ (cái shí zhī sān sì ěr 裁什之三四爾). His own Ní Wénzhēngōng niánpǔ 倪文貞公年譜 of his father is a principal documentary source for the latter’s life. CBDB 30757.
