我自从担任官职以来，三次在兴化任职。每次接触士大夫阶层时，必定询问他们中孝顺父母、友爱兄弟的人，以及仁爱深厚、端庄谨慎的人，期望以此倡导良好的社会风气。又因为当地多次发生水患，人们多患有湿邪致病之症，我想找到良医来治愈他们的疾病，众人一致推荐双湖赵先生。不久后，我因轻微疾病就诊，见到他为人谦逊恭谨。等到他论述经络分寸时，如同洞见五脏结聚一般清晰，在当时岐黄（中医）家中堪称第一。于是得知先生原本是高邮人，定居兴化行医，以救死扶伤为志向，足迹几乎遍及江淮地区。他性格谦虚谨慎，喜好施舍，乐于行善。在家品行尤其纯厚笃实，侍奉双亲极为孝顺。遇到生病且贫穷的人来就医，必定赠送药物给他。即使在大寒大暑之时，治病也不停止。同时利用闲暇时间完成了《医学指归》一书，使后来学习医学的人能够了解经络的源流和委末。
根据我对先生的所见所闻，他的孝顺和喜好善行是确实可信的！他的仁爱深厚、端庄谨慎且医术精湛也是确实可信的！我因为关注兴化百姓而连带提及寄居兴化的外地人士，先生正是其中最为纯粹优秀的一位，所以在先生去世时，我曾赠送写有“实心为善”字样的匾额给他。近来听说他的儿子向朝廷请求表彰他的生平事迹，我也因为在兴化任职已久，编辑《兴化县志》即将成书，将先生载入流寓传中。那么先生的志向在于救人，先生的著作也旨在留给后学以救人，阅读他的书也可以领悟到“三折肱知为良医”（比喻阅历丰富，经验充足）的深意。因此借着这本书刊刻的机会，全面叙述先生的生平，并乐意为此作序。

从前范文正公的文章和德行被认为是宋朝一代的完美人物，年轻时曾说：“我不能做优秀的宰相，一定要做优秀的医生。”大概是因为优秀的宰相治理国家，优秀的医生治疗疾病，事情不同但用心和道理则是相同的。然而如果不考察经络脉息，就不足以谈论医学。即使考察了经络脉息，如果不审察病症的寒热虚实，辨别药物的君臣佐使关系，也绝对无法行医。医学难道容易谈论吗？
双湖先生籍贯高邮，居住兴化，是一位笃行君子。年轻时攻读科举学业，诵读过便不忘。侍奉父母孝顺，赡养祖母。祖母生病时，亲自侍奉汤药，苦于没有好的治疗方法，于是专心研习医学，精研脉理。从《灵枢》、《素问》以及张景岳等各家审证、立方、制药的方法，都有确切的心得。我们乡里的龚意太守，曾经担任兴化知县，曾对我说过先生品德纯粹、医术精湛，我心里十分仰慕，但未见过一面。己亥年我在泰州馆舍居住时，才初次结识。到了辛丑年，我来代理兴邑文正书院职务，交往日益密切，每次生病治疗无不痊愈。甲辰年我回乡病重，其他医生都束手无策。偶然检查先生的旧方，服用一剂即痊愈。后来询问原因，先生说病有本有标，这正好适合隔一隔二的治疗法则，他的精细审慎详细周密大多如此。先生天性诚恳真挚，善于继承先人遗志，拯救困苦、抚恤寡妇，乐善好施不知疲倦。去世后，高邮、兴化两县编纂地方志，呼吁上级官员表彰他的孝行。而他的几位贤子能阅读遗书，在医学界享有盛名。长子小湖，继承了前人的美德，四方求诊的病人，与过去无异。今年春天我病了数十天，多位医生治疗无效。长子恰好从外面回来，几帖药后立刻康复，其渊源确实有来源啊。
最近先生手辑的《医学指归》委托我作序，读起来钩玄提要，条理分明，更加相信先生品德纯粹、医术精湛，龚公的话确实不是虚言。我曾经到达盂城，泛舟珠湖，登上文游台，肃穆地想象前代哲人的风流余韵。而兴邑有得胜湖，又是昔日贤者范文正公治理的地方，先生自号双湖，是否有心仰慕范文正公“良相良医”的说法，选择其中之一来救济世人呢？东坡先生认为范公的仁义礼乐、孝弟忠信，是有德之人必然有的言论，先生出版这部书来证明于世，墨迹滋润教化，使百姓达到仁爱长寿的境界，那么优秀的医生确实与优秀的宰相同等功劳，这就是序言。
咸丰元年辛亥闰八月下旬 韵溪愚弟蔡春泉叩首敬撰
Since I assumed my official post, I have served in Xinghua three times. Each time I interacted with the scholar-officials, I invariably inquired about those who were filial and fraternal, as well as those who were benevolent, profound, dignified, and cautious, hoping to set an example for social customs. Furthermore, considering that the region frequently suffered from water disasters and many people suffered from diseases caused by dampness (Shi, 湿), I sought a skilled physician to cure their ailments. Everyone unanimously recommended Mr. Zhao Shuanghu. Shortly thereafter, due to a minor illness, I met him and found him to be modest, respectful, and cautious. When he discussed meridians and pulse positions, it was as if he could see clearly into the internal organs' structures, ranking him among the foremost practitioners of Qi-Huang (Traditional Chinese Medicine) at that time. It was then I learned that he was originally from Gaoyou but settled in Xinghua to practice medicine, dedicating himself to saving lives, with his footsteps covering almost the entire Jianghuai region. He was humble and prudent, fond of giving alms, and delighted in doing good deeds. His conduct within the family was particularly pure and sincere; he was extremely filial to his parents. When encountering patients who were ill and poor, he would always gift them medicine. Even during extreme cold or heat, he never ceased treating patients. Taking advantage of his leisure time, he completed the book *Yixue Zhigui* (Medical Guide), enabling future students of medicine to understand the origins and details of the meridians.
Based on what I have seen of him and heard from others, his filial piety and love for goodness are indeed credible! His benevolence, profundity, dignity, caution, and medical skill are also indeed credible! Because I care for the people of Xinghua, I extend this mention to those residing there as expatriates. Mr. Zhao is the most outstanding among them. Therefore, upon his passing, I presented him with a plaque inscribed with "Sincere Heart Doing Good" (Shixin Weishan, 实心为善). Recently, I heard that his son requested imperial recognition for his life's deeds. I, having served in Xinghua for a long time, am editing the *Xinghua County Gazetteer* which is nearing completion, and will include Mr. Zhao in the biography of sojourners. Thus, his ambition was to save people, and his book aims to guide future learners to save people. Readers of his work can also comprehend the subtle meaning behind "breaking one's arm three times leads to knowing how to be a good doctor" (Zhe Gong Zhi Wei Liang Yi, 三折肱知为良医). Therefore, taking the opportunity of this book's publication to detail his life story, I am pleased to write this preface.
Respectfully composed by Liang Yuandi, Prefect-level Magistrate of Xinghua County, Lingshi [Clan Name].
In ancient times, Fan Zhongzheng (Fan Zhongyan)'s literary achievements and moral conduct were considered perfect for the Song Dynasty. In his youth, he once said, "If I cannot serve as a capable Prime Minister, I must surely become a capable Physician." This is because while a capable Prime Minister governs the state and a capable Physician treats diseases, the matters differ, but the heart and principles are the same. However, without examining the meridians and pulses, one cannot speak of medicine. Even if one examines the meridians and pulses, without assessing the syndrome's cold-heat and deficiency-excess patterns, and distinguishing the Sovereign-Minister-Assistant-Courier roles of herbs, one absolutely cannot practice medicine. Is medicine easy to discuss?
Mr. Shuanghu was of Gaoyou origin and resided in Xinghua; he was a gentleman of earnest practice. In his youth, he studied for the civil service examinations, memorizing texts effortlessly. He was filial to his parents and cared for his grandmother. When his grandmother fell ill, he personally attended to her medicinal decoctions. Finding no effective treatment available, he devoted himself to studying medicine, meticulously researching pulse theory. From the *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions) to the methods of syndrome differentiation, prescription formulation, and drug preparation by Zhang Jingyue and other schools, he gained definite insights. Mr. Gong Yi, the Prefect of our hometown who formerly served as Magistrate of Xinghua, once told me that Mr. Zhao possessed pure character and exquisite medical skills. I admired him deeply but had not yet met him. In the Ji Hai year, while staying in Taizhou, we finally met. By the Xin Chou year, I came to act as the director of Wenzheng Academy in Xinghua, and our friendship deepened. Whenever I fell ill, his treatments were invariably successful. In the Jia Chen year, I returned home severely ill; other physicians withdrew their hands in helplessness. I accidentally examined an old prescription from Mr. Zhao, and after one dose, I recovered. Later, when I asked for the reason, he explained that diseases have root and branch aspects, and this case perfectly suited the "treat every other layer" method. His precision and meticulousness were typically like this.
Mr. Zhao was naturally sincere and affectionate, good at inheriting ancestral aspirations, rescuing the distressed, comforting widows, and tirelessly loving goodness. After his death, both Gaoyou and Xinghua counties compiled local gazetteers and appealed to higher authorities to commend his filial piety. His virtuous sons read his remaining books and gained fame in the medical field. His eldest son, Xiaohu, inherited the former virtues; patients seeking treatment from all directions were no different from before. This spring, I suffered from illness for several weeks with no effect from multiple doctors. The eldest son happened to return from outside, and after a few doses, I recovered completely. Indeed, his lineage has its source.
Recently, he entrusted me with writing a preface for his hand-edited *Yixue Zhigui* (Medical Guide). Reading it, I found it extracted the essence and summarized the key points, analyzing items in detail and dividing them logically. This further confirmed that his character was pure and his medical skill exquisite; Lord Gong's words were indeed not empty. I once visited Yucheng, boated on Zhu Lake, and ascended Wenyou Terrace, solemnly imagining the lingering style of past sages. Xinghua County has Desheng Lake, which was also the jurisdiction of the former sage Fan Zhongzheng. Mr. Zhao styled himself "Shuanghu" (Double Lakes). Did he admire Fan Zhongzheng's saying of "Capable Prime Minister and Capable Physician," choosing one path to benefit humanity? Su Dongpo stated that Fan Gong's benevolence, righteousness, propriety, music, filial piety, brotherhood, loyalty, and trustworthiness were words inevitably spoken by a virtuous person. Mr. Zhao published this compilation to demonstrate to the world. Its ink nourishes and educates, leading the people to benevolence and longevity. Thus, a capable physician indeed shares the same merit as a capable prime minister. This is the preface.
Respectfully bowed by Cai Chunquan, younger brother of Yunxi, late August of the leap month in the first year of Xianfeng (1851).
