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 Táng-Sòng 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.
