《黄帝内经》说：人受寒邪侵袭，就会发生热病。大概六气（风、寒、暑、湿、燥、火）的运行，大多转化为火热之邪。外感疾病，虽然有因寒或因热引起的区别，但属热的病症较多。霍乱不过是外感病中的一种证候，其中也有寒证、热证，起初并不专门归属于寒证。只是因为它……（原文此处有缺漏）。大概是深深痛恨偏执于单一方法以治疗百病的弊端，所以不惜言辞痛切，如此陈述。读者如果怀疑我偏用寒凉药物，未免会因为文辞而误解了本意了。从前徐灵胎（洄溪）撰写《慎疾刍言》，自己在论述中说：有人怀疑我专门使用寒凉攻伐之法，却不知道这是为了那些误用温补疗法的人……同治癸丑年正月，乌程汪曰桢
随息居士，身处太平盛世，生长在杭州城，不幸幼年丧父。自知没有应对世俗的才能，便以“潜名”作为书斋的名字。十年后，忽然带着两个弟弟，拿着一方砚台回到故乡，然而贫穷得连插锥子的地方都没有，租屋居住。有人问原因，回答说：我是继承先人的志向罢了！于是给草堂题写匾额。到了酉年秋天，局势日益窘迫，无法守护祖先的坟墓，才与两个弟弟分别，带着妻子儿女，栖身于濮院。别人看他像野鹤闲云一样超脱，而他内心却自我悲伤。等到季冬时节，杭州城再次沦陷，漫长的黑夜，更加觉得难以忍受。今年春天，急忙将三、四个女儿草率地嫁出去，夏天躲避战乱到上海，妻子儿女随后到达，在黄歇浦西租赁房屋，仍然命名为随息居。简略叙述这些经过，让翻开书页的人知道，所谓“随处以息”的人，就是半痴山人，身体不能……重订《霍乱论》的原因，是因为道光年间，曾在天台道上起草过《霍乱论》，被海丰张柳吟先生审阅定稿，同郡的王仲安先生刻印发行于世，这已经是二十多年了，刻板保存在杭州和会稽，想必已化为劫灰。咸丰初年，定州杨素园先生，又将《王氏医案》十卷合刻于江西，不知道刻板是否还存在。如今避乱来到上海，恰逢霍乱大规模流行，掌管生命救治的人不知所措，死者确实很多。元和的金君斋，心地仁慈，对此感到悲痛，遍搜坊间的《霍乱论》，想要用来平息这场瘟疫，但不能得到很多，听说我的踪迹，就来与我结交，以此作为登高呼救。我自估量没有拨乱反正的才能，正后悔少年时妄作的错误，惭愧得无法回应。过了两个月，金君斋也因病去世。现在的刻板已经毁坏，书中也没有剩余的了，我读他的书，简明恰当，多采纳民间经验，确实是可流传的作品。因而感叹金君斋韬光养晦之深，竟然不……金君在下，我不敢自忘武勇，认为可以平定这场瘟疫。书成之后，题名为《重订霍乱论》。首先叙述病情，其次叙述治疗方法，其次叙述医案，其次叙述药方，共四篇。
同治建元壬戌闰月丙午日，华胥小隐自己记述
As stated in the *Yellow Emperor's Inner Canon* (Huangdi Neijing): "When humans are injured by cold pathogenic factors, they develop febrile diseases." Generally, the movement of the Six Qi (Wind, Cold, Summer-heat, Dampness, Dryness, Fire) tends to transform into Fire. Although exogenous diseases may be caused by either Cold or Heat, those involving Heat are more common. Cholera morbus (Huoluan) is merely one type of exogenous disease; it can present as either Cold or Heat patterns, and initially does not exclusively belong to Cold patterns. It is simply because... [text missing in original]. The author deeply detests the弊端 (drawback) of rigidly adhering to a single method to treat all diseases, hence speaking with such earnestness and severity. If readers suspect that I bias towards using Cold-Cooling herbs, they would be misinterpreting my intent due to the wording. In the past, Xu Lingtai (styled Huixi) wrote *Shenji Chuyan* (Cautious Words on Preventing Illness), and commented himself: "Some suspect I specialize in using Cold-Cooling and attacking methods, but they do not know this is for those who have been mistakenly treated with Warm-Reinforcing methods..."

The Layman Suixi, living in an era of peace and prosperity, grew up in Hangzhou. Unfortunately, he lost his father in childhood. Knowing he lacked talents for worldly engagement, he named his study "Qianming" (Hidden Name). Ten years later, he suddenly returned to his hometown with his two younger brothers and a single inkstone. However, he was so poor he had no space to drive in an awl, renting a house instead. When asked why, he replied, "I am continuing my ancestors' will!" He then inscribed a plaque for his thatched cottage. By the autumn of the You year, the situation became increasingly dire; unable to maintain his ancestors' tombs, he parted from his two brothers and took his wife and children to reside in Puyuan. Others viewed him as free as a wild crane or idle cloud, while he felt deep inner sorrow. By the late winter, Hangzhou fell again. The long nights became unbearable. This spring, he hastily married off three or four daughters. In summer, he fled to Shanghai (Shenjiang) to avoid chaos. His wife and children followed, renting a house west of the Huangxie River, still naming it Suixi Ju (Suixi Residence). Briefly recounting these events, so that whoever opens the book knows that the person "resting wherever he is" is Half-Foolish Mountain Man (Banchi Shanshan), whose body could not... The reason for revising *Cholera Morbus Treatise* (Huoluan Lun) is that during the Daoguang reign, he drafted *Huoluan Lun* on the road to Tiantai, which was reviewed and finalized by Mr. Zhang Liuyin of Haifeng. Mr. Wang Zhong'an of the same prefecture printed and circulated it. This was over twenty years ago. The woodblocks were kept in Hangzhou and Kuaiji, presumably turned to ashes of kalpa (Jie Hui). In the first year of Xianfeng, Mr. Yang Suyuan of Dingzhou combined it with ten volumes of *Wang Shi Yi An* (Medical Cases of the Wang Family) and printed them in Jiangxi; it is unknown if the blocks survived. Now, fleeing chaos to Shanghai, cholera epidemics broke out widely. Physicians did not know how to cope, and many died. Mr. Jin Zhai of Yuanhe, possessing a benevolent heart, felt compassion and searched everywhere for copies of *Huoluan Lun* to help quell the epidemic, but could not find many. Hearing of my whereabouts, he came to establish friendship, regarding it as a call from a high place. I assessed myself as lacking the talent to restore order, regretting my youthful presumptuous writings, and feeling ashamed to respond. Over two months later, Mr. Jin Zhai also passed away from this illness. The current blocks are destroyed, and no books remain. I read his work; it is concise and appropriate, incorporating much folk wisdom, truly a work worthy of transmission. I sigh at the depth of Mr. Jin's concealment of his talents, yet he did not... Mr. Jin below, I dare not forget my martial spirit, claiming I could pacify this plague. Upon completion, the book was titled *Revised Cholera Morbus Treatise* (Chongding Huoluan Lun). It covers four sections: first, the condition of the disease; second, treatment methods; third, medical cases; fourth, herbal formulas.
