There are two versions of the *Shanghan Lun* (Treatise on Cold Pathogenic Diseases). One is the Song Edition, which was collated and revised by Gao Baoheng and others during the Zhiping era of the Song Dynasty. The other is the annotated version by Cheng Wuji of the Jin Dynasty. Additionally, the *Jingui Yufan Jing* (Essential Prescriptions of the Golden Cabinet) is also an alternative version of the *Shanghan Lun*, sharing the same content but with a different name; it was likely transmitted from before the Tang Dynasty and generally aligns with the citations found in the *Qianjin Yi Fang* (Supplement to Thousand Golden Prescriptions). (The *Waitai Miyao* (Essential Prescriptions from the Imperial Library of Ten Thousand Years), in its post-script for the Chaihu Jia Mangxiao Tang (Bupleurum Decoction plus Gypsum), cites the *Yufan Jing*, and the formula matches that of the current standard edition.) The citations in the *Mai Jing* (Pulse Classic) and the *Waitai Miyao* have minor differences. Since Fang Youzhi, various commentators have endeavored to restore the original text. (Note: The "Cheng" edition is now included in the *Yitong Zhengmai*; there are also collated editions by Wang Jichuan, Wang Zhizhong, Zhang Suichen, etc. The copy held in my family is uniquely a Yuan dynasty print, likely an old edition from Liaoshe.) There are some slight variations among them, which are generally due to subjective modifications by individual scholars rather than corrections based on other extant versions. The "Shu Edition" mentioned by Fang Youzhi and the "Ancient Edition" mentioned by Cheng Yingmao are of unknown printing dates and are particularly questionable. The currently circulating Song block-printed edition was facsimile-carved by Zhao Kamei of the Ming Dynasty. Although not the original, the text is upright and preserves the format of the Zhiping era. (The Cheng Wuji annotated version has slight differences; only the content recorded in the *Ming Lilun* sometimes matches the Song text. Furthermore, Li Shizhen's *Bencao Gangmu* (Compendium of Materia Medica) records that in Zhang Zhongjing's *Shanghan Lun*, Ren Shen (Ginseng) and Chai Hu (Bupleurum) were written as "Ren Shen" and "Zi Hu". This version is no longer seen in the world today; only Cheng Wuji's phonetic annotations record "Shen" pronounced as "Shen" and "Zi" pronounced as "Chai", confirming this was indeed the ancient text.) The current original text strictly follows the Song edition, and all textual variants from other editions are annotated under each clause for reference.
The book is titled *Jiyi* (Collected Meanings). For each clause, I have thoroughly studied the annotations of various schools, examined them with an open mind, weighed right from wrong, and collected those interpretations that best fit the original text. Sometimes one or two schools are cited per clause, while at other times multiple views are combined. Generally, the order is determined by logical coherence, without rigid adherence to the chronological sequence of the commentators. Redundant language is deleted, and essential meanings are condensed to avoid repetition that might confuse the reader, aiming instead for clarity of meaning and integration of intent. However, regarding missing characters or erroneous texts where the meaning is difficult to grasp, I tentatively list several explanations without definitively judging their correctness, leaving such matters for future scholars. The cited commentators follow the conventions established by Wang of Jintan. [Cheng] refers to Cheng Wuji (*Shanghan Lun Zhujie*). [Zhao] refers to Zhao Sizhen. [Chen] refers to Shen Liangchen. (The above two are cited in the *Zhongjing Quanshu*.) [Jian] refers to Zhang Jianshan (cited in *Yixue Zhunsheng*). [Wang] refers to Wang Yutai (*Shanghan Zhunsheng*). [Fang] refers to Fang Youzhi (*Shanghan Tiaobian*). [Yu] refers to Yu Chang (*Shanghan Shanglun Pian*). [Xu] refers to Xu Bin (*Shanghan Yuanfang Faming*). [Cheng] refers to Cheng Yingmao (*Shanghan Hou Tiaobian*). [Qian] refers to Qian Huang (*Shanghan Suyuan Ji*). [Ke] refers to Ke Qin (*Shanghan Lun Zhu*). [Zhou] refers to Zhou Yangjun (*Shanghan Sanzhu*). [Zhang] refers to Zhang Lu (*Shanghan Zuanyuan*). [Zhi] refers to Zhang Zhicong (*Shanghan Lun Jizhu*). [Yin] refers to *Shanghan Zongyin* (by Zhang Zhicong). [Xi] refers to Zhang Xiju (*Shanghan Zhijie*). [Wei] refers to Wei Litong (*Shanghan Lun Benyi*). [San] refers to Wang Sanyang (*Shanghan Gangmu*). [Wang] refers to Wang Hu (*Shanghan Bianzhu*). [Min] refers to Min Zhiqing (*Shanghan Chanyao Bian*). [Lin] refers to Lin Lan. [Shen] refers to Shen Mingzong. [Zheng] refers to Zheng Chongguang. [Zhi] refers to Cheng Zhi. [Ju] refers to Wu Renju. (The above six are cited in the *Yizong Jinjian*.) [Jian] refers to the *Yizong Jinjian* (Imperial Compilation by Emperor Qianlong). [Wu] refers to Wu Yiluo (*Shanghan Fenjing*). [Shu] refers to Shu Zhao (*Zai Chongding Shanghan Lun Jizhu*). For these commentators, I do not provide specific exegesis but instead establish separate discussions to elucidate the meaning of the classic, serving as annotations beyond annotations, attached after each clause. Their names and bibliographic details are omitted here to avoid verbosity.
Some commentators propose novel theories that may initially seem plausible but ultimately mislead later generations. In such cases, I briefly refute them and annotate these refutations after the respective clauses.
Ancient and modern medical texts often use Zhang Zhongjing’s formulas to construct case studies or modify them. These serve to inspire clinical application. Therefore, I append relevant cases and modifications following the respective formulas as encountered.
Textual exegesis is not typically within the deep purview of clinicians; however, descriptions such as "wen wen" (a sensation of warmth or discomfort), "neck stiffness," and "falling prone" require understanding. Without grasping their meaning, clinical practice may encounter hesitation. Thus, I carefully investigate and cite evidence for these terms, appending them to the end of clauses, not out of a desire for erudition but for clarity.
Regarding erroneous texts or missing characters in the treatise, I dare not arbitrarily delete or alter them. Instead, I annotate them after each clause, adhering to the Han Confucian tradition of revering the classics.
