Hú Zhīyù 胡祗遹 (1227–1295), zì Shàokāi 紹開 (per Yuánshǐ; the Sìkù editors suspect this is a transcription error for Shàowén 紹聞, since Hú’s family-letter quotes the Zhōushū Kānggào “shàowén yīdé yán”), hào Zǐshān 紫山, posthumous shì Wénjìng 文靖, native of Wǔān 武安 in Cízhōu 磁州 (Héběi). In Zhōngtǒng beginning (1260) recruited by Zhāng Wénqiān 張文謙 (Vice-Director-of-the-Left at Dàmíng) as yuánwàiláng; entered the central Zhōngshūshěng as xiángdìngguān; in Zhìyuán 1 (1264) by imperial edict joined the newly-founded Yuán Hànlínyuàn as Yìngfèng Hànlín wénzì concurrent Tàichángbóshì — playing a major role in restoring the Yuán ritual-and-music system. Successively Hùbù yuánwàiláng, Zuǒyòusī; ran afoul of the senior Mongol financial-administrator Ahmad Fanākatī (Āhāmǎ 阿哈瑪) and was nominally lenient-promoted out of the central government to Vice-Director of Tàiyuán with concurrent tíjǔ tiěyě (iron-foundry inspection); replaced as Hédōng tíxíng fùshǐ; rose to JīngHúběidào xuānwèi fùshǐ, Jìnínglù zǒngguǎn, ultimately Jiāngnán Zhèxīdào tíxíng àncháshǐ. Posthumously promoted Lǐbù shàngshū in Yányòu 5 (1318), shì Wénjìng. His original 67-juàn collection was lost; the present 26-juàn Zǐshān dàquánjí KR4d0443 was reassembled by his son Hú Chí 胡持 and his student Liú Gēng 劉賡. Yuánshǐ j. 170.
