我在咸丰末年，为躲避战乱流寇而身处海上，当时瘟疫盛行，流离失所的百姓接连死亡，我对此毫无办法去救助，这才深知医学对于人的迫切重要性。既然学习医术已有多年，于是汇集各家学说，考证文献、剖析义理，校订注释《伤寒论》和《金匮方论》两书；接着撰写《金匮要略》的论述概要，因为收集各种病症，解释名称与形态，确立义例，撰写《证原》及脉法篇章；接着又认为治病关键在于处方，因此阐发经方并撰写《释例》；接着又认为处方的关键在于辨别药物，因此撰写《校注神农本草经》。此外那些解读经典的著作，随着完成便随手丢弃，仅收录保留下来的，得一百多篇，分为四卷，命名为《研经言》。请教通达之士，作为日后自我审视的借鉴。我资质愚钝，凡所论述，不敢故意追求高深，独自标榜新奇特异。只致力于切近平实，力求符合古人书籍中的义理罢了。古书不是说过吗？获取知识在于推究事物的原理，书也是事物的一种，阅读并推究它，以获取知识，这将是推广医学的途径。如果说这对医学技艺有所裨益，那就留给有才能的人吧。

百病的成因有八种：一是邪气，二是水湿，三是鬼神，四是虫兽，五是器物，六是饮食，七是药石，八是人事。前五种在身外，后三种在身内。而在八纲之中，各自都有具体的数目分类。属于邪气的，有风、日、雾、瘴，有寒、暑。属于水湿的，有露、雨，有水。属于鬼神的，有冲击，有丧尸，有精魅，有祸祟。属于虫兽的，有咬螫，有影射，有遗毒，有触气。属于器物的，有金属箭头，有打压，有触伤，有汤火烫伤。属于饮食的，有禁忌不当，有过量食用，有五味所伤，有中毒。属于药石的，有服药过量，有用药错误、石毒、鸦片之毒。属于人事的，有喜、忧、欲、恚、恐等情志，有行、立、坐、卧等体态，有举重闪挫，有堕坠跌仆。总计其项目，二十多项。打算引用古代论述，扩展成一卷，但未能及时完成，在此略作序述。
In the final years of the Xianfeng reign, I sought refuge at sea to escape bandits and rebels. During that time, epidemics prevailed, and refugees died in succession; having no means to save them, I came to realize the urgent necessity of medicine for humanity. Having studied medicine for many years, I compiled various theories, examined texts, and analyzed their meanings, producing a collated and annotated edition of *Shanghan Lun* (Treatise on Cold Pathogenic Diseases) and *Jingui Fanglun* (Essential Prescriptions from the Golden Cabinet). Subsequently, I wrote an outline of the *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet), collecting various symptoms, explaining their names and manifestations, establishing principles, and writing chapters on the origin of diseases (*Zhengyuan*) and pulse diagnosis methods. Further, recognizing that treating disease lies in prescribing formulas, I elucidated classical prescriptions by writing *Shili* (Explanation of Examples). Again, recognizing that prescribing lies in distinguishing herbs, I produced a collated and annotated edition of *Shennong Bencao Jing* (Divine Farmer's Materia Medica). Other works interpreting classics were discarded as they were completed; retaining only those preserved, I obtained over one hundred essays, arranged into four volumes, titled *Yanjingyan* (Reflections on Classical Studies). I submitted these to learned scholars, hoping they would serve as a mirror for my future self-reflection. Being unwise, I dare not deliberately pursue profundity or claim novelty. I only strive for practicality and plainness, seeking to align with the principles found in ancient texts. As the classic says, "Acquiring knowledge lies in investigating things." Books are also things; by reading and investigating them, we acquire knowledge, which will thereby expand the field of medicine. If this contributes to this art, let it await those who are capable.
Autobiographical Preface by You Su of Tiaochuan
The causes of a hundred diseases are eight: first, pathogenic factors (Xieqi); second, water and dampness (Shuishi); third, ghosts and spirits (Guishen); fourth, insects and beasts (Chongshou); fifth, utensils and objects (Qiwu); sixth, diet and food (Yinshi); seventh, drugs and minerals (Yaoshi); eighth, human affairs (Renshi). The first five are external to the body, while the last three are internal. Within the Eight Principles (Bagang), each category has specific sub-numbers. Those belonging to pathogenic factors include wind, sun, fog, miasma, cold, and heat. Those belonging to water and dampness include dew, rain, and standing water. Those belonging to ghosts and spirits include shock/impact, zombie possession, spirit enchantment, and disaster curses. Those belonging to insects and beasts include bites and stings, shadow influence, residual poison, and toxic air contact. Those belonging to utensils and objects include metal arrowheads, crushing pressure, blunt trauma, and scalds/fire burns. Those belonging to diet include dietary taboos, excessive intake, injury from the Five Flavors (Wuwei), and poisoning. Those belonging to drugs and minerals include overdose of medication, medicinal errors, mineral toxicity, and opium toxicity. Those belonging to human affairs include emotional states such as joy, worry, desire, resentment, and fear; postures and movements such as walking, standing, sitting, and lying down; strain from lifting heavy objects leading to sprains; and falls, drops, and tumbles. In total, there are more than twenty categories. I intended to cite ancient discourses and expand this into a volume, but did not have the leisure to do so; thus, I briefly record this preface here.
