朱君携至宣城。谋与李令宗仁。绣梓以传于四方。且请予序诸首。予惟传曰。如保赤子。赤子甚不易保也。而是书亦未

《保幼大全》是我的同僚朱时佐先生为了造福世人而刊印的著作。书中论述医理极其精微严密，制定方剂极其详尽完备。大概从人成形之初，直到长成儿童，各种细微的病症，无不具备。可惜作者失名了。相传此书是从古墓中得到的，虽然未必确实，但用它来治疗疾病，没有不有效的，这确实是天地间的一部奇书。
朱先生将其带到宣城，与李宗仁县令商议，刻印此书以流传到四方，并且请我为它作序放在卷首。我想到古语说：“像保护婴儿一样（爱护百姓）。”婴儿是很不容易保护的，而这本书也不容易得到。得到它的人不私自据为己有于一家一邑，而是想要流传到四方，并且将惠及后世，使所有的婴儿都能得到保护他们的方法，从而安然处于长大长寿的境界。这两位君子的用心，难道不是既公正又广博吗？保护婴儿，就是保护百姓。如果保护百姓的人，真能像保护婴儿那样（尽心竭力），而百姓还有不安定的，我不相信会有这种情况。因此写下这篇序言。

《保幼大全》，就是《小儿卫生总微论方》的别名。因为它的制方和论述，详细审慎、精密，所以又命名为《保幼大全》。我向来颇有救济万物的志向，见到医家的书籍，常常喜欢收藏。挥使郑和先生，是精通儿科的医生，与我关系友好。我问他是精通医术的缘故，他便拿出这本书给我看。我阅读这本书，发现它与寻常医书不同，又询问他得到这本书的缘故，他说：相传是农夫在古墓中得到的。于是我请求抄录，郑先生没有为难的神色，于是把全集交给我。我抄录并珍藏在箱子里已有多年了。偶尔遇到小儿疾病，按照方子尝试使用，往往获得奇特的疗效。有一天，我与宣城令李宗仁先生一起询问民间疾苦，在官署相遇，谈到这本书。李先生也是一个乐于救济万物的人，便取来刊印它，以扩大其流传。不到几个月就完成了。唉！我在当今圣明时代领取俸禄，对百姓的贡献已经很久了。如果让一二个年幼的儿童，能凭借这本书在危急仓促之际得到万分之一的救助，我平素的志愿，难道不是也能稍感欣慰吗？至于医术的高低，高明的人自然能够体会，不必等我多说。姑且记下它的由来罢了。
弘治己酉年中秋早晨，京闱戊子科乡贡进士、宁国府通判、世族济南朱臣时佐书写。
*Baoyou Daquan* (Comprehensive Guide to Protecting Infants and Children) is a work printed by my colleague, Mr. Zhu Shizuo, for the benefit of the world. Its discussion of medical principles is extremely subtle and rigorous; its formulation of prescriptions is extremely detailed and comprehensive. It covers, from the initial formation of human life until childhood, all minute pathological manifestations without exception. It is a pity that the author's name has been lost. It is said that it was obtained from an ancient tomb; although this may not be entirely certain, its use in treating diseases has proven universally effective. Indeed, it is a rare book in the world.
Mr. Zhu brought it to Xuancheng and discussed with Magistrate Li Zongren the printing of woodblocks to disseminate it throughout the four corners of the land. He also requested me to write a preface for it. I recall the saying: "To protect [the people] as one protects an infant." Infants are indeed difficult to protect, and this book is likewise hard to obtain. The person who obtains it does not keep it private to one family or locality but wishes to disseminate it widely, thereby benefiting future generations. This allows all infants to acquire the methods of protection, enabling them to grow up safely and live long lives. Are not the intentions of these two gentlemen both just and extensive? To protect infants is to protect the people. If those who govern the people could truly care for them as they would care for infants, and yet the people remained unsettled, I should not believe it. Thus, I write this preface.
Written on the 15th day of the 7th lunar month in the autumn of Jiyou Year, Hongzhi Era, by Fan Ji, courtesy name Yizhen, of Tiantai, who received the Jin degree through imperial examination, held the rank of Zhongshu Dafu (Middle Gentleman), and served as Prefect of Ningguo Prefecture, Zhili.
*Baoyou Daquan* is another name for *Xiao'er Weisheng Zongwei Lunfang* (General Treatise on Infant Hygiene). Because its prescriptions and discussions are detailed, prudent, precise, and rigorous, it is again named *Baoyou Daquan*. I have long harbored the ambition to aid beings. Whenever I encountered medical texts, I delighted in collecting them. Commander Zheng He was a physician specializing in pediatrics and a close friend of mine. When I asked him how he attained his proficiency in medicine, he presented this book to me. Upon reading it, I found it differed significantly from ordinary medical texts, so I inquired further about how he came by it. He replied that it was traditionally said to have been found by a farmer in an ancient tomb. Consequently, I requested a copy. Mr. Zheng showed no reluctance and thus handed over the complete collection to me. I transcribed it and treasured it in my cabinets for many years. Occasionally encountering cases of pediatric illness, I applied the formulas from this book and often achieved remarkable results. One day, while accompanying Magistrate Li Zongren of Xuancheng to inquire into the hardships of the people, we met at the government office. Discussing this book, Mr. Li, who was also eager to benefit others, took the initiative to print it, thereby broadening its dissemination. Within a few months, the task was completed. Alas! For a long time, I have drawn a salary in this enlightened era without contributing sufficiently to my people. If even a few young children could receive a fraction of help in times of crisis due to this book, would not my lifelong aspiration find some comfort? As for the high or low quality of the medical art, the discerning will understand it naturally; there is no need for my words. I merely record its origin here.
Written on the morning of the Mid-Autumn Festival in the year Jiyou of Hongzhi, by Zhu Chen, courtesy name Shizuo, of Jinan, a member of a prominent clan, who passed the provincial examination (Jiangxi) in the Wuzi year and served as Vice Prefect of Ningguo Prefecture.
