Founding-Míng Hànlín compiler and prose-canon-formator, native of Línhǎi 臨海 (Táizhōu 台州, Zhèjiāng). Zì Bóxián 伯賢; hào Zōuyáng zǐ 鄒陽子 (“Master Zōuyáng”, after the Hàn rhetorician Zōu Yáng 鄒陽). In Yuán Zhìzhèng 21 (1361) presented a Héqīng sòng 河清頌 to the court but was not given audience. In Hóngwǔ 3 (1370) summoned to the capital to participate in the compilation of the Yuán shǐ; in Hóngwǔ 6 (1373) compiled the Hóngwǔ rìlì 洪武日厯 (the daily records of the Hóngwǔ court for the first six years); appointed Hànlín biānxiū 翰林編修; in Hóngwǔ 7 (1374) participated in the compilation of the Hóngwǔ zhèngyùn 洪武正韻 [official Míng rhyme-dictionary]; subsequently transferred to Jìnfǔ yòu chángshǐ 晉府右長史 (Right Steward of the Princely Establishment of Jìn) and died in office in Hóngwǔ 9 (1376) at age 63.
Of major significance for the history of Chinese literary canon: Zhū Yòu compiled a Bā xiānshēng wénjí 八先生文集 in the late 1360s / early 1370s — a selection of the prose of Hán Yù 韓愈, Liǔ Zōngyuán 柳宗元, Ōuyáng Xiū 歐陽脩, Zēng Gǒng 曾鞏, Wáng Ānshí 王安石, and the Three Sūs (Sū Xún, Sū Shì, Sū Zhé) — which the Sìkù tíyào of his collected works KR4e0020 identifies as the textual prototype of the later canonical TángSòng bā dà jiā 唐宋八大家 grouping that Máo Kūn 茅坤 anthologized in the late Míng. The anthology itself does not survive; the eight-master canon is its legacy.
