Chéng Guólíng 程國齡 — variant catalog form of 程國彭 Chéng Guópéng (zì Zhōnglíng 鍾齡, original zì Shānlíng 山齡, hào Xìnghǎi yīnjūn 杏海隱君, 1662–1735), the Hīzhōu Xīnān physician of the Kāngxī / early-Yōngzhèng era. The Kanripo catalog meta records the same author under both names: KR3er048 Yīxué xīnwù (under 程國彭) and KR3er113 Yīxué xīnwù zázhèng yàoyì (under 程國齡). The discrepancy is a scribal alternation between péng 彭 and líng 齡 (the original name was Shānlíng, of which Zhōnglíng / Guólíng are zì-variations, with Guópéng a separate alternative form); the modern Chinese-medicine consensus treats these as a single author.
