Lǐ Rúguī 李如圭 (Southern Sòng, fl. Shàoxī era ca. 1190s; CBDB id 10620 has fl. earliest 1193). Zì Bǎozhī 寳之. Native of Lúlíng 廬陵 (modern Jí’ān, Jiāngxī). Jìnshì of Shàoxī 4 (1193) — corrected here from Chén Zhènsūn’s incorrect “Chúnxī guǐchǒu” (which corresponds to no actual year, since the Chúnxī era 1174–1189 contains no guǐchǒu; the Sìkù tíyào of KR1d0030 reasons that “Shàoxī guǐchǒu = 1193” is the intended date and that Chén made a one-character transcription error). Career rose to Fújiàn lù fǔgān 福建路撫幹 (Pacification-Office Officer of Fújiàn Circuit).
A friend of Zhū Xī 朱熹 (1130–1200) — Zhū Xī collaborated with him on critical-edition work for the Yílǐ. Author of three Yílǐ studies in the Sìkù: KR1d0030 Yílǐ jíshì 儀禮集釋 in 30 juan (the principal Sòng-period commentary-anthology on the Yílǐ); KR1d0031 Yílǐ shìgōng 儀禮釋宫 in 1 juan (on the architectural-spatial layout of pre-Qín ritual spaces); and Yílǐ gāngmù 儀禮綱目 (on the chapter-and-section structure of the Yílǐ; lost). The Sòng zhōngxīng yìwén zhì records that “after the Yílǐ was abandoned, scholars no longer chanted it; in the Qiándào era Zhāng Chún (KR1d0029) first corrected its errors as the Yílǐ shíwù; in the Chúnxī era Lǐ Rúguī produced the Jíshì drawing on classics and biographies; further produced Gāngmù to distinguish chapter-and-section purport, and Shìgōng to discuss the system of palace-and-room. Zhū Xī once collaborated with him on critical-edition work — apparently he was learned in ritual.”
