《难经》说：通过观察神色就能诊断疾病，称为“神”；通过听声音、闻气味就能诊断疾病，称为“圣”。这种神圣的诊断精微意蕴，是无法直接传授的。然而，医学的道理完备于阴阳气化的规律之中，通过穷尽万物的本性来通晓人性的道理，而其中最显著的表现则在于方书（记载药方的书籍）。感叹自从秘传的医书未能流传，急救的《肘后备急方》未能获得，那么古代方剂流传于世间的，也都难以阐明其精妙之处了。但也不能说没有精妙之处可以阐明。况且上等的药物保养生命，中等的药物调养性情，下等的药物治疗疾病。治疗疾病的药物，如果不通晓性命（生命本质与情志）的道理，那么疾病又怎么能治愈呢？既然如此，疾病的治疗，是通过方剂来实施的，而保养生命、调养性情，就是所谓方剂的精妙所在。唉！《灵枢》和《素问》，并非不是记载极其广博且为人们乐于称道的，只是担心人们只得到了粗浅的部分而遗漏了精妙的部分，使得古人的优良方法和美好意旨，无法在千百年以上得到面验和继承，那就如同《广陵散》这首曲子断绝不再弹奏一样。只有能够掌握其中的精妙，那么那些极其奇特险峻的方剂，固然因为精妙而达到精妙；那些极其平淡的方剂，更因为不追求奇异而达到精妙。何况通过参考各种方剂，推求善本，这又是集合古人的精妙而获得精妙，并融合古人的精妙而使之更加精妙。这就是所谓的“汇精”（汇集精要）。从前孙思邈著有《千金翼方》，陶宏景著有《集验方》五卷，都流传后世，获益的人很多。施舍药物的功劳，还不如刊印方剂以救济世人的功劳最大。这部书命名为《汇精》，就是在嘉庆九年（甲子年）三月由京江尊仁堂刊印赠送。
第一条：古今的方书，数量多得像让牛出汗、让书堆满屋子一样，经验效验的方子，刊刻出版的也很多。现在从各方本中选择那些屡次有效、屡经验证的，分为内、外、妇、儿四科。
第二条：内、外各科的方剂，妇科和儿科通用。其中有专门属于妇科和儿科的，列为专门章节。至于妇女的胎产和小儿的初生护理，尤为重要。
第三条：奇症急症一门，症状不是常见病症，仓促之间病情奇特危险，拖延就难以救治。所以广泛采集各方以尽到应急救急的意义。
第四条：望、闻、问、切四种诊法，缺一不可。本书在各方的下面详细列出形体和症状，不及脉理。大概是因为脉理难以言说，而形体症状容易理解。
第五条：古今人的元气不同，医学宗派各家已经详细论述过了。这里所辑录的方剂，总以固护和滋养元气为主。如果病症是由于外感客邪引起的，治疗应当采用攻邪的方法。
第六条：本书所收录的方剂，都是参考各种书籍，选择其中好的版本，详细加以校订，以避免错误。使用者千万不要随意议论并加减药味。
第七条：编入书中的如六味地黄丸、八珍汤、补中益气汤、归脾汤等方剂，是常见于其他书籍的，原本不需要再载录。这里因为治疗病症时需求极多，查阅其他版本……（原文此处似有缺漏或排版问题，结合语境意为因常用而重新收录以便查阅）
第八条：本书分定了目录，编定了号数。其中有一方兼治多种症状，一种症状参考使用多个方剂的情况，都在汤引（煎服方法/引导语）下面注明参见前文。
第九条：本书篇幅不多，都是经过验证的经验方。或者居住在乡村僻静处，医生遥远难以求得；或者是旅客在舟车旅途中，便于携带，尤其能得到救济。
第十条：编入书中除了煎剂各方，临症取用之外，其余各门类中的膏、丹、丸、散，有一方兼治多种症状，费用少功效多的，有药材……（原文此处截断，意指药材易得或制作简便等）
The *Nan Jing* (Classic of Difficult Issues) states: "To diagnose by observation is called 'Shen' (Divine); to diagnose by listening and smelling is called 'Sheng' (Sage)." The profound essence of this divine and sage-like diagnostic ability cannot be directly transmitted. However, the way of medicine is complete in the laws of Yin-Yang and Qi transformation; by exhausting the nature of all things, one exhausts the nature of humanity, and the most manifest expression of this lies in formula books. Alas, since secret medical texts were not transmitted and the emergency manual *Zhou Hou Bei Ji Fang* was not obtained, the ancient formulas circulating in the world have also been difficult to elucidate in their essence. Yet, one must not say that there is no essence to be elucidated. Furthermore, superior drugs nourish life, medium drugs nourish character, and inferior drugs treat disease. If drugs used to treat disease do not understand the principles of life and spirit (*Xing Ming*), how can diseases be cured? Therefore, the treatment of disease is conducted through formulas, and the nourishing of life and character constitutes the true essence of these formulas. Oh! The *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions) are not without extensive records that people love to praise; yet there is a fear that one may obtain only the coarse aspects while losing the refined ones, so that the excellent methods and noble intentions of the ancients cannot be verified face-to-face across thousands of years. This would be like the piece *Guangling San* being lost and never played again. Only by grasping its essence can one achieve refinement: even the most extraordinary and unconventional formulas achieve refinement through their essence, and the most plain and simple formulas achieve refinement precisely by not seeking the unusual. Moreover, by referencing various formulas and seeking out good editions, one combines the essence of the ancients to attain refinement, and merges with the ancients' essence to become more refined. This is what is meant by "Hui Jing" (Collecting Refinements). In the past, Sun Simiao wrote *Qian Jin Yi Fang* (Supplement to the Thousand Golden Formulas), and Tao Hongjing wrote *Ji Yan Fang* (Collected Verified Formulas) in five volumes; both were passed down to later generations, benefiting many. The merit of distributing medicinal herbs is not as great as the merit of printing and disseminating formulas to aid the world. This compilation is titled *Hui Jing*. It was printed and distributed by the Zun Ren Tang of Jingjiang in the third month of the Jiazi year, the ninth year of the Jiaqing reign.
Item 1: Ancient and modern formula books are numerous enough to make oxen sweat and fill houses with books. Experience-based formulas have also been published frequently. Here, from various sources, we select those that have proven effective repeatedly, categorizing them into Internal Medicine, External Medicine, Gynecology, and Pediatrics.
Item 2: Formulas for internal and external conditions are generally applicable to gynecology and pediatrics. Those specifically dedicated to women and children are listed as specialized sections. Among these, pregnancy, childbirth, and neonatal care are particularly important.
Item 3: The section on rare and acute conditions addresses symptoms that are not common; in sudden emergencies, the condition is peculiar and dangerous, and delay makes rescue difficult. Therefore, we extensively collect various formulas to fulfill the purpose of emergency relief.
Item 4: Observation, listening/smelling, inquiry, and palpation (pulse-taking) are indispensable. This book details physical signs and symptoms under each formula but omits pulse theory. This is because pulse theory is difficult to articulate, whereas physical signs and symptoms are easier to understand.
Item 5: The primordial Qi (*Yuan Qi*) of people in ancient and modern times differs, a point detailed by various schools of medical thought. The formulas compiled here primarily focus on consolidating and nourishing primordial Qi. For conditions caused by exogenous pathogens, the treatment should involve attacking/expelling the pathogen.
Item 6: The formulas recorded in this book are selected from various references, choosing the best editions and carefully collating them to avoid errors. Users must not arbitrarily discuss or modify the prescriptions.
Item 7: Formulas such as Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia), Ba Zhen Tang (Eight-Treasure Decoction), Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction), and Gui Pi Tang (Restore the Spleen Decoction) are commonly seen in other books and originally did not need to be reprinted. However, due to their frequent clinical use, they are included here for convenience of reference... [Text fragment]
Item 8: The book has a defined table of contents and numbered entries. For cases where one formula treats multiple symptoms, or one symptom is treated by referring to multiple formulas, cross-references are noted under the decoction instructions.
Item 9: The volume is small, containing only experience-proven formulas. They are suitable for those living in remote rural areas where doctors are hard to find, or for travelers carrying them on boats and carts, providing significant assistance.
Item 10: Besides the decoctions for clinical use, other categories such as pastes, pills, powders, and elixirs are included. Some single formulas treat multiple conditions, offering high efficacy at low cost, with accessible ingredients... [Text cuts off]
