[Tang Daliè (styled Lisan) *Wu Yi Hui Jiang* (Collected Lectures of Wu Physicians)] Ten volumes. Extant.
Preface by the author states: I have investigated how Yan Di (Shennong, Divine Farmer) recorded substances, first establishing the classic of *Ben Cao* (Materia Medica); Yun Rui named official positions, initiating the archives of *Ling Lan* (Spiritual Orchid). Transmission through generations established various schools of thought; lineages evolved to the present, excelling especially in collection and recording. Jiang of Huangnan compiled classified medical cases; Luo of Dongyi selected collected essences. Precisely because origins are distinct, there are many chroniclers. Moreover, our Wu region is a land of abundant literature and a domain where excellent physicians gather. The Han brothers enjoyed reputations comparable to Lu Yi (Bian Que); the Ge father and son inherited the learning of Zhang Zhongjing and Liu Wansu. The twenty descendants of Xinpu Qidong had prolific writings in previous dynasties; Shengzhou, Luyu, and other gentlemen made significant contributions in the current era. *Yin Ji Cao* reveals Yuan Yi’s caution in clinical practice; *Du Shu Ji* shows Zai Jing’s profound scholarship. All these works stand alone, originating from various scholars' perspectives. During the Kangxi reign, Guo Jun Yizhi collected the treatment records of many sages and carved them into a book titled *Wu Yi Zhong An* (Medical Cases of Wu Physicians). This was again a work compiled by collecting every minor merit and utilizing every skill, searching widely and gathering extensively. Broadly listing effective results serves not only to record the models of local ancestors but also to demonstrate the achievements of gentlemen through their own discussions. Furthermore, those who master this profession possess considerable talent, and those who understand its principles naturally have outstanding insights. Those who hide their brilliance do not lack secrets kept in pillows; spiritual ingenuity and subtle thoughts are certainly not devoid of treasures in bags. All such hidden knowledge, how could it be bearable to regret? I have carefully followed the old edition of *Wu Yi Zhong An* to compile a new edition of *Wu Yi Hui Jiang*. Profound meanings and explicit words are unified for seeking instruction; long passages and short sections are treated without rigid constraints. If one can follow in the footsteps of predecessors, one should expect to not yield when duty calls. Thus, holding firm to one's will, not seeking glory, expressing deep thought together, and appreciating novelty mutually. Whether omitting past teachings to uncover covered truths and extract subtleties, or originating from independent judgment to grasp newness and mark differences, interpreting the secrets of jade plates with joy matching the divination of Lize, and seeking true words from the Golden Casket, all align with the celebration of gathering. Do not say that among thirty secret prescriptions, Sun Simiao alone obtained the wonder; know that the four compilations of *Zhou Hou Bei Ji Fang* (Handbook of Prescriptions for Emergencies) are not merely Pao Pu Zi exhausting their depth. Although turning flowers into honey might invite criticism of bibliomania, collecting armpit fur to make a robe suffices to fill gaps in the forest of arts. Mid-Autumn of Renzi year in Qianlong era, Tang Daliè Lisan wrote at Wenxin Caotang in Changzhou.

[Shen Dancai *Yi Pu* (Medical Canon/Chart)] Not seen.
Preface by Qian Daxin states: Shen Dancai belongs to a prominent family in our county. In his youth, he abandoned the civil service examination path and devoted himself exclusively to medical formulas, Five Elements, and Ren-Dun divination techniques, possessing divine understanding. He believed that the error of divination lies only in misfortune, whereas medicines primarily aim to treat diseases. Disease names may be the same, yet some arise from external pathogens, others from internal injury; some excess conditions require purging, while deficiency conditions require tonifying. Between similarity and difference, a hair's breadth leads to a thousand miles. Studying medicine consumes human effort and causes particularly severe harm. Therefore, he broadly studied ancient and modern medical texts, classified and collected them, distinguished the sources of disease, and thereby mastered the application of prescription formulation, creating several volumes of *Yi Pu*. Upon completion, he prepared to have it printed and asked me to write a preface. I replied to Dancai: Do you know the saying about judging horses? In the past, Bo Le recommended Jiu Fang Gao to Duke Mu of Qin. The Duke sent him to find a fine horse. Three months later, he returned and reported: "I found it." It was a mare and yellow. When the envoy went to fetch it, it turned out to be a stallion and black. The Duke summoned Bo Le to reprimand him, saying: "The man you sent to find a horse couldn't even tell color or gender, how could he know horses?" Bo Le sighed deeply and said: "Has his skill reached such a level? What Jiu Fang Gao observes is the heavenly mechanism. He grasps the essence and forgets the coarse; focuses on the interior and forgets the exterior. He sees what he needs to see and ignores what he does not need to see. This is why he surpasses me by thousands." Ma Yuan of the Han Dynasty studied bone-judging under Yang Zi'a in his youth. When campaigning in Jiaozhi, he obtained a bronze drum from the Luoyue people and cast it into a horse model. He believed that hearing reports is inferior to seeing with one's own eyes, and viewing shadows is inferior to observing forms. Thus, based on Yi Shi's thigh bones, Zhongbo Shi's teeth, Xie Shi's lips, and Ding Shi's body proportions, he prepared these several families' bone structures as standards. Bo Le, regarding horses, observed only their heavenly mechanism, not bothering to distinguish color or gender. Yet Fubo General (Ma Yuan) haggled over teeth, lips, and thighs, measuring joints inch by inch, seeking exact resemblance. How is this different from superficial observers? However, Bo Les are rare in the world, yet the method of judging horses must be transmitted. To let things reach their full potential and people utilize them effectively, so that swift horses are not trapped pulling salt carts and inferior horses do not mix with superior ones, what else is there to observe besides the Bronze Horse Model of Fubo? Ancients used the cold and warm properties of stones and herbs, measured the depth of diseases, distinguished five bitter and six pungent flavors, formulated water and fire agents, to open blockages and resolve knots, thus giving rise to eleven schools of classical prescriptions. This is like Fubo having a standard for judging horses. But good physicians also say: The highest physician focuses on pulse diagnosis; the subtlety of pulses cannot be transmitted. Listing prescriptions alone is useless to the world. This is what Bo Le meant by observing the heavenly mechanism and ignoring what should not be seen. Now, since you are proficient in pulse diagnosis, seeing clearly within the walls, and have collected methods of diagnosis and treatment from ancient and modern times to create a chart for future generations, does this align with the intent of Fubo? Nevertheless, measuring the cun without reaching the chi, shaking hands without reaching the feet, facing each other for a moment and then prescribing decoctions—this was criticized by former sages and is even more prevalent today. To recognize the truth of diseases and avoid errors of a hair's breadth leading to a thousand miles is extremely difficult. I offer these remarks for your book.

[Anonymous *Jingyun Zhai Ji Yan Fang* (Verified Prescriptions from Jingyun Studio)] Eight volumes. Not seen.
[Rongshan Dexianshi *Pu Ji Ying Yan Liang Fang* (Universal Benefit Verified Good Prescriptions)] One volume. Extant.
Preface by the author states: *Jingyun Zhai Ji Yan Fang*, eight volumes, contains excellent rescue methods covering all diseases. It has been circulated for a long time and is highly valued by people. Now, from the original collection, I have selected concise prescriptions and recorded them in one booklet. Some are added based on other books, but they are all prescriptions verified multiple times. They are compiled and printed, distributed according to capacity. I hope benevolent gentlemen who see this book will feel an irresistible desire to benefit others and surely print and distribute it widely to relieve suffering. Then this printing will be fortunate. Mid-Spring of Jiwu year in Jiaqing era.

[Ye Muqiao *Ping Yi Fang* (Simple and Easy Prescriptions)] Four volumes. Extant.
Preface by the author states: Previously, Mr. Cao Ju'an of Xinjian compiled and edited ten thousand prescriptions classified into categories, divided into 107 sections, accounting for 3,479 symptoms and obtaining over 11,700 prescriptions. Classified and categorized, clear as palm lines, one could say he exhausted his heart and efforts, benefiting the world and future generations significantly. However, among them, some symptoms had two or three prescriptions, and some had dozens. The collection was rich, and the volumes were numerous. For scholars with excellent knowledge, more is indeed better; but for someone with shallow talent and rigid views like myself, it would only cause awe-struck sighing. Moreover, potent toxic drugs are fierce like wild wolves and tigers; if the syndrome is not clearly perceived, the prescription is hard to establish. Now, I only select from Surgery, Gynecology, and Pediatrics, where patterns are fixed and treatments are easier to determine, so the excerpts are broader to prepare for extensive collection. As for Malaria, Stroke, and Cold Damage, these belong to internal syndromes, which are suddenly difficult to distinguish, and changes between deficiency and excess shift rapidly. If fully recorded, one might be constrained by established methods, and a slight error could cause serious delay. Therefore, I kept them brief, and extracted a few items from *Neijing Zhi Yao* (Essentials of the Inner Canon), *Yisheng Weilun* (Subtle Discussions on Nourishing Life), *Chuanzhong Lu* (Records of Passing Truth), and *Jingyan Liangfang* (Experienced Good Prescriptions), adding them to the volumes. Interspersed with control and treatment methods, generally all are safe, harmless, simple, and easy to follow. The principle takes simplicity, hence named *Ping Yi Fang*. However, my understanding is limited like measuring the sea with a gourd or peeping through a tube, far from perfect. I still await experts to adapt according to syndromes and cross-reference according to prescriptions. First day of the second month of spring, Jiazi year, ninth year of Jiaqing, Xiangyan of Wulin wrote the preface.
