Júfāng fāhuī 局方發揮
A Critical Elucidation of the [Hé-jì] Jú-fāng by 朱震亨 (Zhū Zhènhēng, zì Yànxiū, hào Dānxī, 1281–1358, 元)
About the work
Zhū Zhènhēng’s programmatic critique of the Sòng Tàipíng huìmín héjì jú fāng (KR3e0033), in 1 juan — the doctrinal turning-point of the JīnYuán medical revolution. Zhū’s critique focuses on two specific failures of the Júfāng formulary tradition:
- The Júfāng gives prescriptions without aetiological discussion, listing only symptoms — which produces a clinical reasoning that mistakes superficial symptomatic match for true therapeutic match;
- The Júfāng relies extensively on warming, drying, and fragrant-aromatic medicines (温補、燥熱、香竄) — which Zhū argues are catastrophically wrong for the actual yīn-deficiency-fire clinical population of his time.
The work is in dialogic question-and-answer form, with Zhū’s disciples raising particular Júfāng prescriptions and Zhū analyzing each. The work was the proximate cause of the Héjì jú fāng’s decline in clinical authority and the rise of the Sùwèn-grounded JīnYuán medical synthesis. The Míng physician Zhāng Jièbīn (Jǐngyuè) made this work the principal target of his own Jǐngyuè quánshū — defending the Júfāng’s warming-tonifying tradition. The SKQS tíyào offers a balanced reading of the Zhū-vs-Zhāng controversy as a partial-truth disagreement.
Tiyao
Júfāng fāhuī, 1 juan, by Zhū Zhènhēng of the Yuán. Because the Héjì jú fāng does not record disease-source — listing only symptoms under each prescription — the method is convenient but cannot be flexibly applied; Zhū therefore engages each prescription with critical analysis. The principal thrust is to refute warming-tonification and warn against drying-heat.
Zhāng Jièbīn’s Jǐngyuè quánshū says: “The Júfāng was first commissioned by Sòng Shénzōng (N.B. — the prescription was completed under Huīzōng; Jièbīn’s “Shénzōng” is incorrect; we note the correction here) who decreed that high physicians of the empire submit their best [prescriptions]; though some of the prescriptions there are over-decorated, the divinely-effective prescriptions are also not few. How can [Zhū’s] light criticism be allowed?” Jièbīn’s view is rather contrary to Zhū’s.
Examining: Zhū’s learning derives from the Sòng eunuch-Daoist Luō Zhītì of the Yuán court; Luō’s learning is only one transmission removed from Liú Wánsù of Héjiān. Wánsù’s principal-strategy is fire-clearing (㵼火); Zhū’s principal-strategy is yīn-supplementation (滋陰). One attacks the surplus with fierce-and-sharp prescriptions; one supplements the deficiency with mild-and-balanced prescriptions — but the broad meaning does not depart from the source-tradition. Therefore, on the Júfāng’s aromatic-camphoraceous-and-drying medicines (香竄燥烈諸藥), Zhū repeatedly carefully distinguishes [the cases].
Since the Míng, those who follow Zhū’s wave have often used huángbǎi 黄蘗 and zhīmǔ 知母 to damage the original-qì. Zhāng Jièbīn took warning from this end-stage abuse and accordingly took yìhuǒ (boosting fire) as the principal strategy, attacking Liú-and-Zhū without sparing.
Comparing them: “ice-and-snow severe cold” cannot be called “harmonious”; “sky-clear, sun-warm” can be called “harmonious” — that is the figure [the warming-school] uses; but “clear-wind cool-rain” also cannot be called “non-harmonious”, and “melting-stone, flowing-metal [intense heat]” also cannot be called “harmonious”. Each side illuminates one meaning while forgetting that they each cling to one extreme — the failures are similar. Therefore Jièbīn’s view cannot be unknown, but Zhū’s compilation also cannot be discarded.

Abstract
Composition window: 1340–1358, the late mature period of Zhū’s career. The work cannot be precisely dated.
The work’s significance:
(a) The doctrinal turning-point of the JīnYuán medical revolution: Zhū’s Júfāng fāhuī is the work that decisively turned Chinese medicine away from formulary-based clinical practice toward aetiology-grounded clinical reasoning. The work made the SùwènNánjīng classical-textual tradition the doctrinal foundation of post-Yuán Chinese medicine.
(b) The dialogic-critical method: Zhū’s editorial choice — engaging individual Júfāng prescriptions in question-and-answer form with his disciples — is one of the more methodologically interesting Chinese medical-critical techniques. The dialogic form preserves the actual debate-and-clarification process of late-Yuán medical pedagogy.
(c) The Zhāng Jièbīn-vs-Zhū Zhènhēng controversy: this work is the principal source for the long-running Chinese medical-doctrinal debate between yīn-tonifying (Zhū) and yáng-tonifying (Zhāng Jièbīn) schools. The debate dominated Chinese medical theory through the Qīng.
(d) The SKQS editor’s balanced reading: the tíyào’s use of meteorological metaphors — ice-and-snow vs. sky-clear-sun-warm vs. clear-wind-cool-rain vs. melting-stone-flowing-metal — to characterize the four extreme positions is one of the more elegant pieces of mid-Qīng medical-historical analysis.
(e) The textual error caught by the SKQS editors: Zhāng Jièbīn’s misattribution of the Júfāng commission to Shénzōng (1067–1085) rather than Huīzōng (1100–1125) — flagged here per CLAUDE.md instructions. The actual Dà-guān-period collation under Chén Shīwén dates to 1107–1110 under Huīzōng.

Other points of interest
The Júfāng fāhuī is one of the most consequential single short works in Chinese medical history. At only 1 juan, it crystallized the JīnYuán medical-doctrinal critique of the Héjì jú fāng tradition and made the SùwènNánjīng classical-textual reasoning the foundation of post-Yuán Chinese medicine. Its impact is measurable in the dramatic shift from Júfāng to Sùwèn-grounded citations in Chinese medical literature from the late Yuán onward.
The Zhāng Jièbīn / Zhū Zhènhēng controversy is one of the great Chinese medical-doctrinal debates. It addressed a fundamental question — whether the “default” therapeutic strategy should lean warming-tonifying or cooling-tonifying — that no medical tradition resolves once-and-for-all and that requires renewed clinical assessment in each generation.
The “ice-and-snow vs. sun-and-warmth” meteorological metaphors of the SKQS tíyào are one of the more philosophically interesting Chinese medical-historical analyses, recognizing that medical-doctrinal debates often reflect the inherent multi-polarity of medical reality rather than the truth-or-falsehood of either position.
