Lǚ Zhōng 呂中 (fl. 1247–1252), zì Shíkě 時可. Native of Jìnjiāng 晉江 in Quánzhōu 泉州 (modern Fújiàn). Jìnshì of the Chúnyòu era (1241–1252; precise year not preserved). A late-Sòng scholar in the lineage of the Yǒngjiā 永嘉 school of Yè Shì 葉適 (1150–1223) and Chén Fùliáng 陳傅良 (1137–1203) — whose method was institutional-historical realism and jīngshì 經世 (statecraft) rather than xìnglǐ 性理 speculation. His teacher cannot be securely identified, but the preface to his major work attaches him to the second-generation Yǒngjiā school inheritance through Yè Shì’s circle.
His central-court positions were Aide of the Imperial University (Guózǐjiàn chéng 國子監丞) concurrent with Reader-Lecturer of the Chóngzhèng Hall (Chóngzhèngdiàn shuōshū 崇政殿說書), in the late Chúnyòu era. He was subsequently transferred out as Instructor at Zhàoqìng prefecture (Zhàoqìng jiàoshòu 肇慶教授) in Guǎngdōng — a typical late-Sòng demotion for politically controversial central officials.
His major surviving work is the KR2o0011 Sòng dàshìjì jiǎngyì 宋大事記講義 in 23 juàn — a Northern-Sòng dynastic-history textbook composed from his Imperial-University lectures, posthumously edited and circulated through the late Yǒngjiā-school network. The work is one of the most valuable Southern-Sòng witnesses to Northern-Sòng administrative practice, often preserving institutional details not in the Sòngshǐ treatises or in KR3a0023 Mǎ Duānlín’s Wénxiàn tōngkǎo. CBDB id 20668 (no lifedates recorded). His birth and death years are uncertain; floruit 1240s–1260s.
He is sometimes confused with an earlier Yuán scholar of the same name; the Jiǎngyì author is the Jìnjiāng (Quánzhōu) Lǚ Zhōng.
