Yè Shí 葉時 (Southern Sòng, fl. Lǐzōng era 1224–1264; CBDB id 49772 has no birth/death years). Zì Xiùfā 秀發, native of Qiántáng 錢塘 (modern Hángzhōu). Under Lǐzōng he held the post of Lónggétú gé xuéshì 龍圖閣學士 and Guānglù dàfū 光祿大夫, retiring with the title and posthumously canonized as Wénkāng 文康.
A friend of Zhū Xī 朱熹 (1130–1200) — although the chronology requires careful attention, since Zhū died decades before Lǐzōng’s accession, so the friendship was in Yè Shí’s youth. Author of KR1d0007 Lǐjīng huìyuán 禮經會元 in 4 juan (100 chapters), a topical treatise on the Zhōulǐ organised not as a line-by-line commentary but as substantive essays on selected institutional themes. The work is a strong critic of Wáng Ānshí’s New Policies and a defender of the ChéngZhū Dàoxué tradition. Yè agrees with Chéng Yí that “only after [the moral conditions described in] Guānjū and Línzhǐ obtain can the institutional framework of the Zhōuguān be put into practice” — i.e., the institutions of the Zhōulǐ require prior ethical-cultivation foundations and cannot be implemented as bare administrative engineering. He also defends an unorthodox position holding that the Dōngguān “need not be supplied” (sympathetic to the Yú Tíngchūn tradition of KR1d0006), and accuses Héjiān Xiànwáng 河間獻王 of having compromised the Zhōulǐ by appending the Kǎogōngjì.
His main entry in CBDB id 49772 (Sòng); three additional CBDB records under the same name belong to other dynasties (Yuán, Míng) and are unrelated.
