Lǐ Qíqīng 李耆卿, also known as Lǐ Tú 李塗 (the zì–míng relation is the conjecture of the Sìkù editors: the Yǒnglè dàdiǎn recension of Wénzhāng jīngyì attributes the work to one Lǐ Qíqīng “without indication of date or place”, while Jiāo Hóng’s 焦竑 Jīngjí zhì 經籍志 lists a “Lǐ Tú, Wénzhāng jīngyì, 2 juǎn” with matching surname and title, hence the inference that 耆卿 is the zì of 塗). A Southern Sòng literary critic; no biographical data survive. His one extant work, KR4i0042 Wénzhāng jīngyì 文章精義, takes “liùjīng” (the Six Classics) as the source of all prose excellence, refuses to subordinate prose to phonic regularity or sentence-craft, and most strikingly — for a Southern Sòng writer — gives “even-handed” verdicts on both the Sū 蘇 (Mín 岷) and Chéng 程 (Luò 洛) schools, breaking the bitter partisan habit of the day. He was famous in his time (the Sìkù preface remarks that his coinages “Hán’s prose like the tide, Sū’s prose like the sea” 韓文如潮，蘇文如海 and the “spring silkworm spinning its cocoon” 春蠶作繭 metaphors entered general usage), but his book was lost in independent transmission by the Míng and survives only because the Yǒnglè dàdiǎn preserved it. The Sìkù recension is the only modern source. No CBDB id matches.
