Zhào Hóngzhì 趙弘智 (572–653; CBDB id 93988), native of Hénán 河南 (Luòyáng), was a scholar-official of the Suí and early Táng known for his Confucian classical scholarship. His name is given in the Sìkù tradition as 趙宏智 (the bìhuì form avoiding the Qiánlóng emperor’s personal name 弘曆). Under the Suí he served as Tàizǐ Zhōngshèrén 太子中舍人 and Wénlín láng 文林郎; under the Táng he rose through Hóngwén guǎn xuéshì 弘文館學士, Tàizǐ shī 太子師 and ultimately Lǐbù shàngshū 禮部尚書 (Minister of Rites). He was renowned as a jīngshī 經師 (“master of the Classics”), and Táng Tàizōng is recorded in the Jiù Táng shū as having said of him, “Zhī gǔjīn shū zhě, wú yú Zhào Hóngzhì 知古今書者, 無踰趙弘智” (“of those who know books ancient and modern, none surpasses Zhào Hóngzhì”). His chief catalog contribution is as one of the four named compilers of Ōuyáng Xún’s Yìwén lèijù 藝文類聚 (KR3k0003). His biographies are in Jiù Táng shū 188 and Xīn Táng shū 198.
