胎产一科，存亡系乎呼吸，利病关乎终身，于医道尤为切要，学医者尤不可不讲明而切
究之
也。先世名医，如朱丹溪、薛立斋诸公论之綦备。然求其操乎至要，简而易从者，则莫若《
胎产指南》一书。是书原序云∶“出自单南山。其人里居、名字，已不可考，昔越郡钱升
先生，得此秘本，而精子胎产之科，名冠一郡。乾隆癸巳，吾乡伊芳学曾先生，在宁郡道暑

，示后人当神明于法之中，不容偏执，名曰《女科医案》，凡七卷。然先生奉《指南》为枕
中秘，未尝轻以示人，即戚友亦不得而知也。先生殁后，其甥明经蔡益亭先生始得，抄而传
之。欧君孔章，少受举业于益亭，悦是书，手为抄录，久欲梓行于世，以广厥传，猝猝未果

道。而乃眷眷焉垂意于医，诚以医虽小道，而其利济于世者为不浅也。欧君虽不敢与二公颉

妇科中的胎产一科，关乎生命的存亡，影响一生的健康与疾病，在医学之道中尤为关键重要，学习医术的人尤其不可不深入探究并透彻理解它。
先前的名医，如朱丹溪、薛立斋诸位先生，对此论述得非常详尽完备。然而，若要寻求那些抓住最关键要点、简明且易于遵循的著作，则没有比《胎产指南》这一本书更好的了。
这本书的原序中说：“此书出自单南山之手。此人的籍贯居住地、名字，已经无法考证。过去越郡的钱升先生，得到了这本秘传之书，精通胎产专科，名声冠绝一郡。乾隆癸巳年（1773年），我同乡的伊芳学曾先生，在宁波郡道的暑天，从绍兴的朋友娄君手中得到这本书，于是也凭借胎产医术在我的家乡闻名。经过四五十年的阅历，他将所经验的内容笔录成书，告诫后人应当在法则之中运用神妙之变，不容许偏执一端，书名定为《女科医案》，共七卷。然而先生将《指南》视为枕中秘宝，未曾轻易展示给人看，即使是亲戚朋友也不知道。先生去世后，他的外甥、举人蔡益亭先生才得以得到，抄录并流传开来。欧孔章先生年轻时向蔡益亭先生学习科举学业，喜爱这本书，亲手抄录，长久以来想要刻印发行于世，以广泛传播，但匆忙间未能实现。今年秋天编纂修撰宗谱，事情即将完成，负责谱务的天台陈彩盅先生，知道欧君想要做这件事，更加鼓励他，于是嘱咐陈君将其交付给刻工，并将伊芳先生的医案附在后面。过去唐代晋国公退休在家时，曾经亲手抄写《集验良方》，刻印发行于世。宋代范文正公也是如此，并且他说：‘如果不能做优秀的宰相，就愿做优秀的医生。’这两位先生造福世人、延寿百姓的功业，哪里说得完呢？而他们竟然如此眷顾在意于医学，确实因为医学虽然被视为小道，但它对世间的利益救济是非常深远的啊。欧君虽然不敢与这两位先生比肩高低，但他刻印发行这本书的心意，仍然像这两位先生一样。我赞赏他的心意，因此叙述其缘起如下。有人说：凡是星象、面相、医学、占卜之类，如果有秘传之书，不应该泄露宣扬。如果刻印发行，就不灵验了。这种说法，大概与儿童的见识没有两样，反而恰好成为某些人推脱借口的理由，这确实是大方之家所私下鄙视的。哪里值得辩解呢，哪里值得辩解呢。”
咸丰六年（1856年）九月，葵圃周丹忱撰写。
The specialty of obstetrics and gynecology, particularly regarding pregnancy and childbirth, hangs in the balance of a breath, and its benefits or harms concern one's entire life. It is especially crucial within the medical arts; therefore, those who study medicine must not fail to investigate it thoroughly and understand it clearly.
Famous physicians of earlier generations, such as Zhu Danxi (Zhu Zhenheng) and Xue Lizhai (Xue Ji), discussed this subject exhaustively. However, if one seeks works that grasp the most essential points, are concise, and easy to follow, none surpasses the book *Taichan Zhinan* (Guide to Pregnancy and Childbirth).
The original preface of this book states: "This work originates from Shan Nanshan. The person's hometown, residence, and name are now untraceable. In the past, Mr. Qian Sheng of Yue Commandery obtained this secret text, mastered the specialty of pregnancy and childbirth, and his reputation topped the commandery. In the Gui Si year of the Qianlong reign (1773), my fellow townsman, Mr. Yi Fangxuezeng, while serving in Ningbo Commandery during the summer heat, obtained this book from his friend Mr. Lou in Shaoxing. Consequently, he also became famous in our county for his expertise in pregnancy and childbirth. After forty or fifty years of clinical experience, he recorded his experiences into a book, instructing future practitioners to apply divine flexibility within the rules, without allowing bias or rigidity. He titled it *Nuke Yian* (Medical Cases of Women's Diseases), comprising seven volumes. However, Mr. Yi regarded *Zhinan* as a secret treasure kept at his pillow and never lightly showed it to others; even relatives and friends were unaware of it. After Mr. Yi passed away, his nephew, the Juren Cai Yiting, finally obtained it, copied it, and circulated it. Mr. Ou Kongzhang studied the civil service examination curriculum under Mr. Yiting in his youth. Delighted by this book, he copied it by hand and long wished to have it printed and published to spread its transmission, but due to hurried circumstances, this was not realized. This autumn, while compiling the genealogy, the task was nearing completion. The genealogist, Mr. Cai Zhong of Tiantai, knowing of Mr. Ou's intention, further encouraged him. Thus, Mr. Ou entrusted Mr. Cai to hand it over to the engravers and appended Mr. Yi Fang's medical cases. In the past, Duke Jin of the Tang Dynasty, after retiring to his home, personally copied *Jiyan Liangfang* (Collected Effective Good Prescriptions) and had it published. Fan Zhongyan of the Song Dynasty did likewise, stating, 'If I cannot be a good prime minister, I wish to be a good physician.' The achievements of these two dukes in benefiting the world and prolonging people's lives are beyond recounting. Yet they devoted themselves so attentively to medicine, truly recognizing that although medicine is considered a minor art, its benefit and relief to the world are profound. Although Mr. Ou dares not compare himself with these two dukes, his intention to publish this book remains similar to theirs. I appreciate his intent and thus narrate its origin as follows. Some say: For categories such as astrology, physiognomy, medicine, and divination, if there are secret texts, they should not be disclosed. If printed and circulated, they will lose their efficacy. This view is no different from childish reasoning and merely provides an excuse for those who withhold knowledge; it is indeed despised by great masters. What is there to argue about? What is there to argue about?"
