秦子皇士，是上海人。年少时便胸怀救济天下的宏大志向，于是潜心钻研医学，对于古今的医书方剂，没有不通晓透彻的。他始终以黄帝、神农创立生命宗旨的思想为根本指向，他在临症诊治时，必定极力探究病症的根本与末梢，以及病情的轻重缓急，推究至极其细微之处。他曾说：“我并非想要精通医术，只是希望内心反省而无愧疚罢了。”这真是仁德君子的一片用心啊！因此他的名声极大，海昌距离海邑，相距不止四百里，但他的名声却像邻里间一样广为人知。如果不是德行深厚的人，怎么能做到这样呢？
我以前四处奔走，深深以不能当面请教而感到遗憾。自从壬午年冬天，我接受特别选拔进入内廷侍奉皇帝，才更加远离了当代的贤士。然而秦子这个人，实际上德行日益广大，名声日益洪亮，四方贤能的士大夫闻风远道迎接他的人日益增多。乙酉年春天，他应嘉禾之邀前往，途经并停留在我所在的地方，救治那些危重病人不计其数，他的名声更是充盈于耳畔。
我想古人学问成名、事业确立后，必定亲手撰写一部著作，公之于世。如今秦子的学问如此精深，名声如此显赫，如果没有任何流传下来以公开于世，那么古代那些致力于救济天下的人也不至于此。到了季冬，单升陈子来京城参加春闱考试，恰逢家人拿着几卷方书，名叫《症因脉治》，大约五六百册。我进屋翻阅，发现这是秦子皇士所著的书籍。书中分门别类，无不兼顾根本与末梢，对轻重的把握和缓急的处理得当，直接让读者依据这本书，自然能达到神妙而化境的境界，人人都可以掌握命运（即通过医术改变健康状态）。
随后，宇瞻及仲季诸位先生，捐资刻印此书，以供世人使用。他们坚决请求我为此书作序，写在书的最前面。我不禁跃然大喜，认为秦子那救济天下的志向，大概能够流传无穷了。各位先生光照天下后世的功效，也符合我将其公之于世的意愿。
康熙乙酉年除夕日，赐进士出身、现任翰林院编修、通家弟查慎行 撰书
Qin Zi Huangshi was a native of Shanghai. In his youth, he harbored the lofty ambition to benefit and save the world, so he devoted himself to the study of medicine, becoming thoroughly proficient in ancient and modern medical texts and prescriptions. He took as his guiding principle the foundational philosophy of the Yellow Emperor (Huangdi) and Shennong regarding the preservation of life. In clinical practice, he invariably strove to exhaustively investigate the root and branch of diseases, as well as their severity and urgency, pushing his analysis to the most minute details. He once said, "My goal is not merely to master medicine, but to ensure that my conscience remains clear." This truly reflects the mindset of a benevolent gentleman. Consequently, his reputation became widely renowned. Although Haichang was more than four hundred li away from Haiyi, his fame spread as intimately as if it were known among neighbors. Could this have been achieved by anyone other than one of great virtue?
In the past, I traveled extensively, deeply regretting the inability to seek instruction face-to-face. Since the winter of the Renwu year, when I was specially selected to serve in the inner court, I had become increasingly distant from contemporary scholars. However, Qin Zi's actual virtue grew ever greater, and his reputation ever more resonant; virtuous scholars and officials from all directions came from afar to welcome him, day by day increasing in number. In the spring of the Yiyi year, he accepted an invitation to Jiahe. Upon arriving at my locality, he cured countless critical cases, and his name filled the air with praise.
I reflected that in ancient times, when learning was mastered and reputation established, one would necessarily compile a book to share with the world. Given Qin Zi's profound scholarship and illustrious reputation, if nothing were transmitted to the public, those ancient figures who sought to benefit the world would not have acted thus. Later in the winter season, Chen Zisheng came to the capital for the Spring Examination. It happened that his family members brought several volumes of medical texts titled *Zhengyin Maizhi* (Symptom, Etiology, and Pulse Diagnosis), comprising approximately five or six hundred fascicles. Upon reviewing them, I discovered they were authored by Qin Zi Huangshi. The work categorized conditions meticulously, addressing both root and branch, and appropriately balancing severity and urgency. It enabled readers, by relying on this text, to naturally attain a state of divine efficacy and transformative mastery, allowing everyone to alter their destiny through healing.
Subsequently, Mr. Yuzhan and the brothers Zhongji donated funds to have the book engraved and printed for public use. They earnestly requested me to write a preface to place at the beginning of the volume. I could not help but leap with joy, believing that Qin Zi's ambition to benefit the world might now be perpetuated indefinitely. The merit of these gentlemen in illuminating the world and future generations aligns perfectly with my intention to make this work public.
