Lín Jiōng 林駉 (fl. mid-13th c.), zì Désòng 德頌, sobriquet Sānshān xiānshēng 三山先生, native of Níngdé 寧德 in Fújiàn. He won the prefectural xiāngjiàn 鄉薦 through the Yì jīng but did not advance to jìnshì; he turned to writing and teaching at home, with neighbouring counties competing to invite him as tutor. His biography appears in the Mǐn shū 閩書 (Fújiàn local gazetteer). His chief surviving work is the Gǔjīn yuánliú zhìlùn 古今源流至論 (KR3k0031) — qiánjí, hòují, xùjí (30 juan by his hand) — a late-Southern-Sòng cèlùn examination crammer; the work’s fourth biéjí (10 juan) was added by his colleague Huáng Lǚwēng 黃履翁.
