余读孟英之《霍乱论》也，在道光纪元之二十有八年。阅三载，孟英游江右时，余握篆宜黄，始纳交于孟英，因得
读其《回春录》《仁术志》诸治案，为之编纂排比，付诸剞劂，以惠世人。孟英知余耽情竹素，积嗜成癖，所获奇方秘籍，
恒邮寄相示，拓我见闻。而余每有所疑，驰书相问难，孟英为之条分缕析，援古证今，如冰斯开，如结斯解，披函庄诵，
未尝不抚案称快。数载以来，尺书往复，鱼雁为劳。夫疾 人之所时有也，不有药石，患害曷瘳？然而医籍流传，途径

温热一证，庸手妄为治疗，夭札多矣，梦隐悯之而作此书，俾学人得所遵循，生平着述等身，当以此书称首，真宝
书也。甚友乌程汪曰桢。读而善之，因为之赞曰∶活人妙术，司命良箴。不偏不易，宜古宜今。千狐之裘，百衲之琴。

自古以来，百姓的疾病中，没有比伤寒更严重的了。生死往往在呼吸之间决定，成败取决于一朝一夕，病情变化万千，不容许丝毫混乱。而在伤寒之中，温热、暑湿等病证，病因并非单一，尤其容易混淆，所以前贤各自撰写专书，互相阐发，对此极为重视。然而，明白这一方面的人往往对另一方面感到困惑，争论纷纷，各自宣扬自己的见解，只是让好学之士无所适从。或者有人过分相信某一家的言论，难免产生偏颇之害。王孟英先生学识渊博，贯通古今，引用经典驳斥异端，兼收并蓄众家之美。他认为前人的学说既然已经切中要害，何必再重复表达自己的观点，因此摒弃瑕疵，收录精华，汇编成《温热经纬》一书。这大概是秉承“述而不作”的意思，而其中夹杂的按语，也是旁考其他书籍，结合个人阅历，这也算是“述”罢了！而且中间并没有私心臆断的成分。我愚昧不懂医术，交往之余，私下听闻绪论，高兴的是长沙（张仲景）的学问，既得到前各家学者的表彰，又得到王氏后来的厘定修订，从此千秋绝学，不至于被各种言论所混淆。而四季五气的感受，也不至于难以辨别而导致错误，这对拯救百姓生命的好处，难道小吗！受托写序，于是我不自量力地写下了这些文字。
咸丰二年壬子初夏 仁和赵梦龄
我在道光二十八年读孟英的《霍乱论》。过了三年，孟英游览江右时，我在宜黄掌管印信，才开始与孟英结交，因而得以阅读他的《回春录》《仁术志》等医案，为他编纂排比，刻印出版，以惠及世人。孟英知道我沉迷于书籍，积习成癖，获得的奇方秘籍，常常邮寄给我看，开阔我的见闻。而我每当有疑问，便写信去询问辩难，孟英为我条分缕析，援引古代验证当今，如同冰融化、结解开，打开信件庄重诵读，没有不拍案叫好的。几年来，书信往来频繁，鸿雁传书辛劳。疾病是时常发生的，如果没有药物，祸患怎能痊愈？然而医籍流传，途径多歧，争论纷纷，各持己见，使后学者彷徨迷惑，无法决定听从谁，有识之士对此感到担忧。我常常想广泛搜集百家之言，综合各家学说，吸取精华，抛弃糟粕，编成一本书，以此向好学深思之士请教，但才识浅陋，不敢自信，想要等到财力稍充，邀请孟英共同商讨，完成这件大事，浮沉数年，而志向始终未能实现。不久军事兴起，粤西贼寇起事，攻占长沙，屠戮武昌，陷落安庆，于是占据金陵。江西左接安徽右连湖北，以长江为门户，大官商议保甲团练以巩固疆土，当时我从宜黄改任临川，虽然地处腹地，但民气向来浮躁，谣言繁多。张扬恐怕生事，犹豫又怕养奸，早晚忙碌于文书之间，这件事便无暇顾及。不久先父在家乡去世，我奔丧回家，战乱载途，道路阻塞，于是取道长沙，泛舟洞庭，渡过江汉，在武昌以南，逆流而上向西，到达樊城，弃船上车，浏览许昌的遗迹，登上大梁的故墟。感慨地发出怀古之思，等到渡河时桑梓在望，故里不远，正要渡过滹沱河，突然遭遇贼寇，急忙折返向东，旅居在丰宁之间。大概迂回六千里，奔驰五个月，却始终未能回家。甲寅年秋天，烽烟稍平，才得以祭扫祖先坟墓，安葬先父。十年游子，重返破屋，邻里故人，半数凋零，追忆往昔，感叹不已！住了几个月，又被公事牵绊，买船南下，因而得以在武林拜见孟英，握手言欢，历叙离别之情。而孟英技艺更加精湛，学问更加深邃，涵养深厚纯正，纯粹表现在面容上，我因为行程紧迫，未能深谈，怅惘而别。不久孟英来答谢拜访，车夫背着巨大的箱子放在船中，那是孟英赠送的书。船行正苦于岑寂，得到这些奇书，如同亲近良友，于是依次阅读，其中有一编，题名为《潜斋丛书》。急忙阅读，原来是孟英几年间搜集的医学书籍。有的表彰前人的美德，有的抒发心得，有的采集奇方像《肘后备急方》，有的区别品类像《本草图经》。端坐篷窗下，偶尔反复诵读，奇妙的情感和思绪，层见叠出，满纸灵光，与严陵山色争奇斗艳。唉！技艺达到这种境界了。士君子能成就不朽的盛业，成为百姓托付性命的人，他的精神必定强固，志虑必定专一，学问必定博洽，蕴蓄必定深厚，而上天也必定给予宽闲的岁月，以成就他的志向。孟英怀才抱奇，隐居不做官，而致力于医学，所以造诣如此，难道是偶然的吗！我走到玉山，遇到贼寇不能前进，仍返回武林，住在孟英那里。早晚交往，相处甚欢，因而一起阅读他的《温热经纬》。所谓经纬，是以轩岐、仲景为经，叶薛诸家为纬，体例完全沿袭《霍乱论》的旧制，而理论更加纯粹，论述更加详细。言语是前人的言语，而意旨却是前人达不到的。我对这件事，心中怀藏数年，无法着手，孟英已经奋笔写成此书。洋洋洒洒，数十万言，没有一个字多余杂乱在其中，这是何等的才华奇特和见识精辟啊！将来由此类推各种杂证，力辟榛芜，独开异境，为这门学问集大成，确实是千秋快事啊。我对孟英的学问，不能望其项背，而孟英谬赞引我为知己，这大概就是所谓超越形骸之外，别有精神契合吧！于是详细叙述始末于书前，以记录交谊的雅致。

温热这一证候，庸医妄加治疗，导致早夭者很多，梦隐怜悯他们而写了这本书，使学习者有所遵循，他生平著作等身，应当以这本书为首，真是宝贵的书。好友乌程汪曰桢读了认为很好，因此为之赞美说：救人的妙术，司命的良箴。不偏颇不改变，适宜古适宜今。千狐之裘，百衲之琴。如果轩辕黄帝、岐伯在世，也会以此为鉴。
同治二年癸亥二月朔 写于上海旅舍
Since ancient times, among the diseases afflicting the people, none has been more serious than Shanghan (Cold Damage Syndrome). Life and death are decided in a breath, success or failure determined in a single day; changes are myriad, allowing for no disorder. Among Shanghan, diseases such as Warmth (Wenre), Summerheat (Shu), and Dampness (Shi) have diverse etiologies and are particularly prone to confusion. Hence, former sages each wrote specialized books to elucidate one another's views, paying close attention to this matter. However, those who understood one aspect were often ignorant of another, leading to heated debates where each proclaimed their own insights, leaving eager students with nowhere to turn. Or, some placed excessive faith in the words of a single school, inevitably causing harm through bias. Mr. Wang Mengying possessed profound and comprehensive knowledge, citing classics to refute heterodoxies, and absorbing the merits of all schools. He believed that since the theories of his predecessors had already hit the mark, there was no need to reiterate his own opinions. Thus, discarding flaws and recording virtues, he compiled the work *Wenre Jingwei* (Warmth Latitude and Longitude). This essentially followed the principle of "transmitting but not creating," while the appended comments, derived from consulting other books and personal experience, also constituted a form of transmission. There was no private speculation involved. I, ignorant of medicine, having exchanged visits, privately heard introductory remarks. I rejoiced that the learning of Changsha (Zhang Zhongjing) had been highlighted by various scholars before, and now refined by the Wang family after, ensuring that this millennium-old masterpiece would not be confused by conflicting statements. The differentiation of sensations from the Five Qi of the four seasons would not lead to misdiagnosis due to difficulty in discernment. How significant is its benefit to human life! Entrusted to write a preface, I presumptuously recorded these thoughts.
Early Summer, Renzi Year, Xianfeng 2nd Year. Zhao Mengling of Renhe.
I read Mengying's *Huoluan Lun* (Treatise on Cholera) in the 28th year of the Daoguang era. Three years later, when Mengying traveled to Jiangyou, I held the seal at Yihuang, and we began our friendship. Consequently, I was able to read his medical cases such as *Huichun Lu* (Record of Reviving Spring) and *Renshu Zhi* (Records of Benevolent Arts), compiling and typesetting them for publication to benefit the world. Mengying knew I was addicted to bamboo slips and books, developing a passion for rare prescriptions and secret manuals, which he often mailed to me to broaden my horizons. Whenever I had doubts, I would write to question him. Mengying would analyze them meticulously, citing ancient precedents to verify contemporary practices, like ice melting or knots untying. Opening his letters and reading solemnly, I never failed to clap the table in satisfaction. For several years, letters passed back and forth, with wild geese bearing messages laboriously. Diseases occur frequently; without medicinal stones, how could afflictions heal? However, as medical texts circulated, paths diverged, debates raged, and each claimed unique insights, leaving later learners bewildered and unsure whom to follow. Scholars lamented this. I constantly wished to extensively collect works from a hundred schools, synthesize diverse views, absorb essences, discard dregs, and compile a book to consult with thoughtful students. But lacking talent and insight, I dared not trust myself, waiting until resources were sufficient to invite Mengying to collaborate on this grand endeavor. Floating and sinking for several years, my ambition remained unfulfilled. Soon, military conflicts arose. Rebels in Western Guangdong rose up, capturing Changsha, slaughtering Wuchang, taking Anqing, and occupying Jinling. Jiangxi, bordered by Anhui and Hubei, used the Yangtze River as a gateway. High officials discussed household registration and militia organization to secure borders. At that time, I transferred from Yihuang to Linchuan. Although located inland, the local populace was restless, and rumors abounded. Ostentation risked causing trouble, while hesitation risked nurturing traitors. Busy morning and evening with paperwork, this matter was neglected. Shortly after, my father passed away at home. I rushed back for mourning. War covered the roads, travel was blocked. I took the route through Changsha, boated across Dongting Lake, crossed the Han and Jiang rivers, went west against the current south of Wuchang to Fancheng, abandoned boats for carriages, viewed ruins of Xuchang, and climbed the old mounds of Daliang. Sighing with ancient nostalgia, upon crossing the river, my hometown came into view, not far away. Just as I was about to cross the Hutuo River, I suddenly encountered rebels, abruptly turned east, and lodged between Fengning. Circling six thousand li, galloping for five months, yet still unable to return. In the autumn of Jiayin year, smoke from beacon fires subsided slightly. I finally paid respects at ancestral graves and buried my father. After ten years as a wanderer, returning to my dilapidated house, half my neighbors and old friends had perished. Recalling the past, I sighed deeply! After residing for a few months, again detained by official duties, I bought a boat heading south, thereby visiting Mengying at Wulin. We shook hands, rejoiced, and recounted our separation. Mengying's skills had become even more refined, his scholarship deeper, his cultivation profound and pure, evident in his demeanor. Due to my urgent schedule, we could not talk deeply, parting in melancholy. Soon, Mengying returned the visit. His porter carried a large trunk onto the boat, containing books gifted by Mengying. Traveling by boat, suffering from loneliness, obtaining these rare volumes felt like welcoming good friends. I read them sequentially. One volume was titled *Qianzhai Congshu* (Collected Works of Qianzhai). Hurriedly reading, I found it was a collection of medical books Mengying had gathered over several years. Some praised former virtues, some expressed personal insights, some collected miraculous formulas like *Zhouhou Beiji Fang* (Essential Prescriptions Worth Their Weight in Gold), some classified categories like *Bencao Tujing* (Illustrated Materia Medica). Sitting upright by the cabin window, occasionally reciting in circles, wonderful emotions and thoughts emerged layer upon layer, full pages glowing with spirit, competing in beauty with the scenery of Yanling Mountain. Alas! Skill reaching such heights. A gentleman who can achieve immortal great deeds and entrust his life to the people must have strong spirit, focused mind, broad learning, deep accumulation, and heaven must grant him leisurely years to fulfill his will. Mengying harbored extraordinary talent, lived in seclusion without officialdom, yet devoted himself to medicine, thus achieving such results. Was this accidental? Arriving at Yushan, encountering rebels prevented further progress, so I returned to Wulin and stayed with Mengying. Daily interactions, getting along very well, we read together his *Wenre Jingwei*. "Jingwei" (Latitude and Longitude) takes Xuanyuan-Qibo and Zhang Zhongjing as the warp (vertical axis), and Ye-Tian-shi, Xue-Lian-cheng, and other families as the weft (horizontal axis). The format strictly follows the old style of *Huoluan Lun*, but the theory is purer, the discussion more detailed. The words are those of predecessors, but the meaning exceeds what they could achieve. I had harbored this idea for years, unable to start, while Mengying had already written this book with vigorous brushwork. Vast and flowing, hundreds of thousands of words, not a single superfluous character mixed in. What extraordinary talent and precise insight! In the future, extending this example to various miscellaneous syndromes, clearing thorns and weeds, opening new realms, gathering the greatness of this path, truly a joy for millennia! I cannot hope to catch up with Mengying's learning, yet he mistakenly regards me as a confidant. This must be what is meant by spiritual connection beyond physical form! Therefore, I detailed the entire process at the beginning of the book to record the elegance of our friendship.
Three days before Dragon Boat Festival, Yimao Year, Xianfeng 5th Year. Preface by Yang Zhaoli of Dingzhou.
Regarding Warmth (Wenre) syndrome, incompetent physicians practicing recklessly have caused many premature deaths. Mengying pitied this and wrote this book, enabling learners to have guidelines to follow. Among his numerous writings, this should be ranked first; it is truly a precious treasure. My friend Wu Cheng Wang Yazhen read it and approved, thus composing a eulogy: Marvelous art saving lives, excellent maxim governing destiny. Unbiased and unchanging, suitable for ancient and modern times. Fur of a thousand foxes, lute of a hundred patches. If Xuanyuan and Qibo were alive, they would take this heart as a mirror.
First day of the second month, Guihai Year, Tongzhi 2nd Year. Written at Shanghai during travel.
