Zēng Yǎn 曾儼 (fl. Kāngxī, late 17th – early 18th century), Qing-period descendant (yìsūn 裔孫) of Zēng Zhào 曾肇 曾肇 (1047–1107). Under Kāngxī he assembled the surviving fragments of his Northern-Sòng ancestor’s literary corpus, which had been all but lost since mid-Míng: he took the zòuyì portion (already reprinted in Yǒnglè 10 / 1412 with Zēng Qǐ 曾棨’s preface) and added recovered zhàozhì, bēibiǎo, and lost pieces, structuring the result as a 4-juǎn recension — the surviving Qǔfù jí 曲阜集 KR4d0064 (3 juǎn of shīwén + 1 juǎn of fùlù).
