Chéng Lín 程林 (zì Yúnlái 雲來, hào Jìngguān jūshì 靜觀居士), early-Qīng physician of Xiūníng 休寧 (modern Ānhuī). Editor of the Shèngjì zǒnglù zuǎnyào 聖濟總錄纂要 (KR3ed013) — a thirty-six-juan abridgement of the massive Sòng Huīzōng-period imperial medical encyclopedia Shèngjì zǒnglù 聖濟總錄 (200 juan, ca. 1118), produced by Chéng’s collation of three damaged copies of the original (still leaving juan 173–177 lost), the substitution of a fellow scholar Xiàng Ruì 項睿’s reconstruction for the lost pediatric prescription juan, and the deletion of the original’s three juan of shénxiān fúěr 神仙服餌 (immortal-elixir ingestion) material as Daoist superstition unsuited to clinical practice. Also author of KR3eq088 Yīxiá zhīyán 醫暇卮言, a miscellaneous medical-essay collection in the zhīyán (digressive notes) genre. Beyond these works he has no transmitted biographical record.
