Biànyì suǒyán 辨疫瑣言
Trivial Remarks on the Discrimination of Epidemic Disease by 李炳 (Lǐ Bǐng, zì Zhènshēng 振聲, hào Xīyuán 西垣, 1729–1805)
About the work
A late-Qiánlóng / Jiāqìng critical commentary on 吳有性 Wú Yǒuxìng’s Wēnyì lùn (KR3eg004), composed by the Yízhēng physician 李炳 Lǐ Bǐng. The work title — suǒyán “trivial remarks” — is a topos of modest authorial self-presentation; the substance is anything but trivial: it is one of the principal mid-Qīng polemical challenges to Wú Yǒuxìng’s prescription apparatus.
Abstract
Lǐ Bǐng’s clinical practice spanned several decades across Húběi, Zhèjiāng, Jiāngsū, and Ānhuī before he settled at the Shàobó / Guāzhōu canal-port. The Biànyì suǒyán synthesises his accumulated clinical critique of Wú Yǒuxìng. The two principal doctrinal positions:
-
Critique of Dáyuán yǐn 達原飲. Lǐ argues that Wú’s signature prescription — bīngláng 檳榔, hòupò 厚朴, cǎoguǒ 草果, huángqín 黃芩, zhīmǔ 知母 — is dangerously administered at the initial stage of pestilential warm-disease, when the pathogen has not yet concentrated into the heat-pattern that the huángqín / zhīmǔ combination is suited to address. Wrongly applied, the prescription “harms the rightful qi and drives the pathogen inward” 反傷正氣，使邪氣內陷. Lǐ’s clinical observation: “in our days, Dáyuán yǐn kills people one after another” 近日達原飲之殺人，比比皆是. Lǐ holds that Dáyuán yǐn should be reserved for the later stage when heat has already concentrated.
-
Critique of Wú’s “no yīn-syndrome” doctrine. Wú had categorically denied that wēnyì presents as a yīn-syndrome. Lǐ counters that on the basis of his own decades of clinical practice, “sānyīn (three-yīn) presentations are present every day”; “two or three doses of Sìnì tāng 四逆湯 or Lǐzhōng tāng 理中湯 will cure them”. This anticipates the rigid/soft pathogen distinction developed independently by 源元凱 Minamoto Genkai a generation later in Japan (see KR3eg025).
The dating bracket reflects Lǐ’s principal active period; the text was conventionally completed in the 1780s–1790s during his late Yángzhōu residency. Lǐ died Jiāqìng 10 (1805); the text was preserved by his friend 焦循 Jiāo Xún in the Lǐ wēng yī jì tradition.
The work is one of the more philologically and clinically sharp Qīng critiques of Wú Yǒuxìng, more rigorous than 王士雄 Wáng Mèngyīng’s later (1852) editorial-comprehensive approach.

Other points of interest
Lǐ’s clinical association with the Yángzhōu polymath Jiāo Xún — author of the famous Lǐ wēng yī jì — links the wēnyì-critical project to the QiánJiā kǎojù 考據 textual-critical tradition. The Biànyì suǒyán is one of the few Qīng medical texts that can be read as a kǎojù-style critical edition of Wú Yǒuxìng’s Wēnyì lùn.
