Wealthy late-Yuán Kūnshān 崑山 patron and literary host. Multiple given names — Yīng 瑛, Āyīng 阿瑛, Déhuī 德輝 — style-name Zhòngyīng 仲瑛. Self-styled Yùshān zhǔrén 玉山主人 (“Master of the Jade Mountain”) after his estate Yùshān cǎotáng 玉山草堂. In youth he was a qīngcái jiékè (free-spending host); at 30 he turned to study and built a substantial literary network. He was recommended for office as màocái and assigned Huìjī jiàoyù, also recruited for the Mobile Secretariat — but declined all. At 40 he handed his entire property to his son Yuánchén 元臣 and devoted the rest of his life to the Yùshān cǎotáng circle, the principal literary gathering-point of late-Yuán Wúzhōng. His patronage made possible the careers of (among many others) Yáng Wéizhēn 楊維楨, Ní Zàn 倪瓚, Zhāng Yǔ 張雨, Kē Jiǔsī 柯九思. After the Yuán fell, his son Yuánchén — a Shuǐjūn fù dōuwànhù under the Yuán — was relocated to Línháo 臨濠 (Hóngwǔ relocation policy); Gù Yīng accompanied him and died there in Hóngwǔ 2 (1369). His self-inscribed portrait verse — “Confucian robe, monk’s hat, Daoist shoes; the green hills of the world can bury my bones; speak of the old days’ chivalric energy: clothes-and-horse on the five-tombs streets of Luòyáng” — is one of the most cited self-statements in late-Yuán literary culture. The Yùshān cǎotáng gatherings are documented in the (separate) Yùshān míngshèng jí 玉山名勝集 and Yùshān cǎotáng yǎjí 玉山草堂雅集. Gù’s own Yùshān púgǎo 玉山璞稿 (KR4d0574) is a single juǎn of his personal compositions.
