Lù Chún 陸淳
Style name Bóchōng 伯沖. Native of Wújùn 吳郡 (modern Sūzhōu). Mid-to-late Táng Chūnqiū scholar, the principal redactor and polemicist of the Dàn–Zhào–Lù 啖趙陸 school of Chūnqiū learning. Disciple of Dàn Zhù 啖助 (zì Shūzuǒ 叔佐, fl. mid 8th c.) for eleven years; junior collaborator and friend of Zhào Kuāng 趙匡 (zì Bóxún 伯循). Late in life he changed his given name to Zhì 質 to avoid the personal-name taboo on Hàn Xiànzōng 漢憲宗 (Lǐ Chún 李純, r. 805–820); he is therefore frequently cited as “Lù Zhì” in late-Táng and Sòng sources. (The Sìkù tíyào corrects the Jiù Táng shū attribution making Lù Chún a disciple of Zhào Kuāng rather than directly of Dàn Zhù; cf. KR1e0013.)
Held a series of mid-rank Táng court positions, culminating in Jǐshìzhōng 給事中 (Imperial Reader). The Xīn Táng shū rúxué zhuàn (juan 168 in some editions) gives him a biography in the Rúxué section. Liǔ Zōngyuán 柳宗元 (773–819) wrote his tomb-inscription, calling Dàn Zhù his teacher and Zhào Kuāng his close friend. He died in 805, the year of Hàn Xiànzōng’s accession.
Three works on the Chūnqiū survive, all built on the lost Chūnqiū tǒng lì 春秋統例 of his teacher Dàn Zhù: Chūnqiū jí zhuàn zuǎn lì KR1e0013 (the constructive systematic statement, 40 chapters in 10 juan, completed 775), Chūnqiū jí zhuàn wēi zhǐ KR1e0014 (the methodological core, 3 juan), and Chūnqiū jí zhuàn biàn yí KR1e0015 (the polemical refutation of the Sān zhuàn, 10 juan). His larger Chūnqiū jí zhuàn in twenty juan, recorded in the Táng zhì, is no longer extant.
The Dàn–Zhào–Lù school’s programme — to read the Chūnqiū directly without forcing each entry through one of the three traditional commentaries — opened the methodological space in which Sòng xīnyì 新義 commentators (Sūn Fù 孫復 KR1e0018, Liú Chǎng 劉敞 KR1e0021, Hú Ānguó 胡安國 KR1e0036) operated. Chéng Yí 程頤 (1033–1107) explicitly praised Dàn Zhù as “a singular figure, of merit in driving back heterodoxy and opening the correct way” — citing the Dàn–Zhào–Lù tradition as a precursor to Dàoxué 道學. Hostile Sòng critics, including Ōuyáng Xiū 歐陽修 and Cháo Gōngwǔ 晁公武, criticised the school for licensing arbitrary speculation; Endymion Wilkinson, Chinese History: A New Manual §48.1.1, gives the modern judgement that the school “opened the path for Sòng learning, and brought the abuse of unrestrained subjective speculation.”
CBDB id 33818 records “陸淳” without lifedates; the death date 805 is inferred from his name-change in the same year.
