Preface by Li Geng: The treatises on medical prescriptions have been transmitted for a long time. Since the advent of written records, although the contents of the "Sanfen" (ancient texts from the times of Fuxi, Shennong, and Huangdi) are no longer accessible to the world, the *Shennong Bencao Jing* (Divine Farmer's Materia Medica) and the *Huangdi Neijing* (Yellow Emperor's Inner Canon), along with the Bagua (Eight Trigrams) of Fuxi, have spanned ancient and modern times, shining brightly like the sun and stars. This indeed proves that medicinal herbs and stones are indispensable to humanity, and medical books are even more essential not to be abandoned in the world. Some argue that medicine is merely a craft and does not warrant writing books. Historians of the Tang Dynasty praised Xu Sizong highly for this view, but they failed to realize that figures like Zhang Zhongjing and Sun Simiao appeared only once every thousand years. If their books on prescriptions were not transmitted, the Way of Medicine might almost have perished. This is a one-sided argument.
Liu Fangming, the Military Governor of Chaoyang in Hunan, while governing and comforting the people, had a particular fondness for medical books. He often worried about the suffering of children with diseases, lamenting not only the lack of good physicians but also the absence of comprehensive pediatric texts. Countless infants died due to misdiagnosis by incompetent doctors; how could their number be calculated? Therefore, he sought out the prescription treatises of ancient sages, family secrets of renowned families in recent times, down to the forbidden formulas of medical artisans and the secret remedies tested by common folk. He visited them all with great care, collecting and recording everything. He appointed Wang Lidao, a staff officer, to oversee the matter, and Wang Zi, a provincial graduate, to compile the book. Although some selected prescriptions may be overly detailed and some arguments somewhat vulgar, generally, they followed the original texts without unauthorized alterations. It took a year for the book to be completed. Unfortunately, Liu Gong did not live to see it, as his illness proved fatal. On his deathbed, he instructed Li Geng, saying, "The *Youyou Xinshu* (New Book for Infants and Children) lacks a preface and introduction. I intended to write them myself, but now it is too late. Please complete them for me." Li Geng replied, "I respectfully obey your command."
Alas! How few scholars and officials possess a heart dedicated to the public good? Their daily thoughts and concerns are usually focused on benefiting themselves while neglecting others, prioritizing relatives over strangers, and viewing things and people through a lens of self-interest. This has been the case for a long time. Confucius once participated in the Za sacrifice and traveled to the Guan in Lu, sighing deeply, saying, "When the Great Way was practiced, the world was shared in common. People did not love only their own parents, nor raise only their own children. When the Great Way declined, the world became private property. People loved only their own parents and raised only their own children." Confucius's sigh was likely directed at Lu. However, is the whole world and subsequent generations any different from Lu? Such situations are ubiquitous. Among the figures of the Eastern Han Dynasty, Diwu Lun was sincere, unadorned, straightforward, and righteous, appearing commendable. One might assume his intentions exceeded ordinary people. Yet when asked if he had private interests, Diwu Lun replied, "When my brother's son was ill, I visited him ten times a night before I could sleep peacefully. When my own son was ill, I did not visit him, yet I slept restlessly all night. I consider myself not free from partiality." If he felt this way about his brother's son, let alone others' sons. If Diwu Lun was so inclined, how much more so those inferior to him? This explains Confucius's sigh. Now, Liu Gong's compilation of this book ensures that fathers and elders across the land need not worry about their children's illnesses, providing care for the young and support for the old. If every household possesses this book and passes it on, the source of blessings will be endless. Is this benefit not extensive? From this, we know Liu Gong's intention is not only blameless in the eyes of contemporaries but also in those of ancients. Prefaced in the mid-autumn month of the 20th year of Shaoxing.
Postscript by Lou Yue: In the autumn of the Gengwu year, Liu Fangming, the Military Governor of Tanzhou, died of illness. I assumed the governorship and inquired among the府 residents. They said Liu Gong governed Tanzhou for a long time, initiating grand projects without negligence. Were there any begun but unfinished? Thus, the *Youyou Xinshu* was brought to my attention. Upon reviewing it, I found that it comprehensively collected prescriptions and treatises for infants and children from ancient and modern medical works. It was organized systematically, categorizing and detailing them like goods in a vast market or gems in a treasury, ready for use according to necessity. Alas! Previously, enthusiasts would hoard a famous prescription, guarding it strictly, even swearing not to pass it to their sons or daughters. Liu Fangming, however, explored extensively, compiled these into a book, had it printed, and shared it with the world. His intention was truly benevolent. I ordered the craftsmen to hasten its completion. I also collected old prescriptions for fertility and appended them as the first volume.
Brief Postscript by Shi Cairu: Liu Gong of Heyang, while serving as Military Governor of Jingxiang, ordered the compilation of pediatric prescriptions from ancient and modern medical texts into a single work, totaling forty volumes, titled *Youyou Xinshu*. Thirty-eight volumes were completed when Liu Gong fell ill and passed away. Lou Gong of Siming, the Transport Commissioner who succeeded him, said, "We must not leave the predecessor's noble work unfinished." He ordered the completion of the task. The remaining two volumes were combined, and a volume of prescriptions for seeking offspring was compiled and placed at the beginning. The book was finished within a month. Alas! It can be said to be thoroughly done.
Chen Zhen Sun stated: *Youyou Xinshu*, fifty volumes, authored by Liu Fangming, Direct Dragon Pavilion Official and Prefect of Tanzhou. He died before the compilation was finished. Xu Shouqing, acting as Prefect while holding the Transport Commissioner post, urged its completion.
Zeng Shirong stated: Insights into regulating infants and children were not recorded during the time of the ancient Yellow Emperor. Gui Yuzhou said that pediatric diseases formed a separate category, hence not included in the *Suwen* (Basic Questions). It began with the *Luxin Jing* (Sutra of the Skull Fontanelle) by shamans, mentioned three times. Later, wise men continued this work, passing down the best practices of various schools. Those refined and systematized for clinical application numbered eighty-one families. Recently, Zhou Zhai of Tanzhou, Hunan, widely collected these writings, compiling them into the *Youyou Xinshu*, forty fascicles, totaling hundreds of thousands of characters, listing famous prescriptions. This seems overly fragmented. It is like a general wanting to disperse an ambush with a single arrow to achieve peace. At that time, selecting one skilled archer was more urgent than mobilizing a million troops. In battle, such a method is impractical. A good general uses both orthodox and unorthodox tactics cautiously. Checking efficacy at the last moment is like digging a well when thirsty or forging weapons when fighting; is it not too late? Physicians who do not thoroughly understand the principles in their minds and the essentials of the *Zhouhou Beiji Fang* (Handbook of Prescriptions Kept Up the Sleeve), but instead hesitate and act arbitrarily out of desperation, bring shame upon themselves. It is like Zhao Kuo, son of Mafulu, engaging in battle recklessly, resulting in defeat. (From *Huoyou Kouyi*)
Note: In the Bingxu year of the Wanli era, Chen Luduan of Guwu published this book, editing the text of prescriptions and treatises. Consequently, the original form of Liu's book has been obscured for a long time. The complete version preserved in the imperial library is a Ming dynasty manuscript. Each volume has two seals: "Descendant of Zhongshan" and "Liu Family of Heyang," indicating a lineage of scholar-physicians, possibly descendants of Liu Fangming. In the Xinhai year of the Kansei era, my ancestor, Lord Lanxi, applied for and obtained a transcription. The catalog of medical collections, authored by Chen Luduan, is quite sparse.
*[Zheng Shi (Duan You) Quan Ying Fanglun]* Twenty-three volumes. Extant.
Note: This book has not been seen in circulation for a long time. In the Jimao year of the Bunka era, Fukui Rotei of Nishi-kyo transcribed it and sent it to me. The letter stated that its format resembled Song dynasty woodblock prints, but Volumes 1 and 2 were missing. Examining the last volume, which recorded commonly treated diseases, contained dates from Shaoxing Gengxu and Qiandao Renwu. This indicates Duan You lived between the reigns of Emperors Gaozong and Xiaozong. The medical source mentioned as "Chunzhong" is likely a typo for "Chunxi." His prescriptions and theories are comprehensive and occasionally offer new insights not found in Liu's *Youyou Xinshu*. It is an indispensable book for pediatrics.

Preface by He Daren: My father possessed twenty volumes of *Xiao'er Weisheng Zongwei Lunfang*, kept in our family collection for over sixty years. The author is unknown. Despite extensive searching, the book had not circulated. From infancy to childhood, it covers the protection of life and summarizes essence and subtlety, being extremely detailed compared to other ancient and modern texts. The author's heart is truly benevolent. Among relatives and friends, when children were ill, I would orally instruct and administer treatments, achieving effects as immediate as shadows. I also adapted some prescriptions for adults, adding decoctions, yielding miraculous results. Perhaps the unspoken brilliance of this book awaits my revelation. How can I keep it as a family treasure without sharing it? Thus, I gathered colleagues to correct copying errors and had it printed at the Imperial Medical Bureau in the capital to spread its transmission. Those who obtain it should use it reverently and know my words are not false. I disregard potential criticism of adding unnecessary details. Alas! The ministers of Qi and Lu are unnamed in history; I regret not knowing more about the author. Prefaced on the Spring Equinox of the Bingwu year of Jiading, by He Daren, Doctor of He'an, Special Envoy and Judge of the Imperial Medical Bureau.
Preface by Zhu Chen: *Baoyou Daquan* (Complete Book for Protecting Infants and Children) is another name for *Xiao'er Zongwei Lunfang*. Because its prescriptions and theories are detailed, prudent, and precise, it was renamed. I have always aspired to benefit beings. Seeing medical books, I enjoyed collecting them. Commander Zheng He was proficient in pediatrics and a close friend. When I asked him about his expertise, he presented this book. I noticed its uniqueness and asked how he obtained it. He said, "It is said a farmer found it in an ancient tomb." I requested a copy. Zheng He readily gave me the complete set, which I copied and treasured for years. Occasionally treating pediatric cases using these prescriptions yielded remarkable results. One day, accompanying Li Zongren, Magistrate of Xuancheng, to inquire about people's hardships, we discussed this book. Li, eager to benefit others, immediately had it printed to spread its transmission. Completed in less than a month. Alas, I have held office during prosperous times without contributing much to the people. If even a few toddlers can be saved from danger by this book, my lifelong wish will be somewhat comforted. As for the skill level, experts will judge it themselves. I merely record its origin.
Summary of the Siku Quanshu: *Xiao'er Weisheng Zongwei Lunfang*, twenty volumes, author unknown. Contains one hundred treatises covering conditions from birth to childhood. Each treatise is followed by prescriptions. It includes a preface by He Daren from the Bingwu year of Jiading, stating the book was in his family collection for over sixty years, author unknown, and he had it printed at the Imperial Medical Bureau to spread it. (Note: Although the Southern Song capital was Lin'an, it was still referred to as "Xingzai" [Temporary Capital] to signify the intent to recover the north, as clearly recorded in *Xianchun Lin'an Zhi*.) Qian Yi of the Northern Song Dynasty gained fame for treating children; his *Yaozheng Zhijue* survives but is incomplete. Other works listed by Chao and Chen, such as *Yingtong Baojian*, *Xiao'er Ling Mifang*, *Xiao'er Yujue*, *Xiao'er Yifang Miaoxuan*, and *Xiao'er Banzhen Lun*, are lost. This book details various conditions, such as stiff tongue and scaly sores, which are not covered in later medical texts. Its discussions are solid and clear, lacking the sectarianism and factionalism prevalent among Ming dynasty physicians. It is indeed an essential book for protecting infants. This edition was printed by Zhu Chen of Jinan in the Jiyu year of Hongzhi at Ningguo Prefecture, renamed *Baoyou Daquan*. Examining the original Jiading preface restores the original title. Zhu Chen's preface claims he received it from physician Zheng He, who found it in a tomb. This story is fanciful, likely fabricated by practitioners to mystify their transmission.
*[Dong Shi (Daying) Huoyou Wushenji]* Twenty volumes. Recorded in Song catalogs. Lost.
*[Anqing Ji]* Ten volumes. Recorded in Song catalogs. Lost.
*[Tang Shi (Minwang) Yinghan Miaojuelun]* Three volumes. Recorded in Song catalogs. Lost.
Chen Zhen Sun stated: *Tang Shi Yinghan Miaojue*, two volumes, authored by Tang Heng of Dongyang. Tang Heng's grandfather, Tang Minwang, was proficient in pediatrics. His son, Tang Lin, passed the imperial examination. Tang Heng, Lin's son, excelled in this ancestral profession, writing ninety-nine articles for this book.
*[Tang Shi (Heng) Boji Yinghan Baoshu]* Twenty volumes. Recorded in Song catalogs (*Zhutang Mulu* lists two volumes). Not seen.
Xiong Jun stated: During the Southern Song migration, Tang Minwang of Nanyang was proficient in pediatrics. His son Tang Lin passed the Jinshi degree. Tang Heng, Lin's son, delved deeply into this study, obtaining official position through it. He narrated his family traditions, including twenty volumes of verified prescriptions, printed at Kuaiji Zhai, titled *Yinghan Baoshu*.

Preface by Zheng Quan: I once heard Fan Zhongyan say, "If I cannot be a prime minister, I will be a good doctor." Is the dignity of a prime minister comparable to the lowliness of a doctor? Their roles differ, but their intent to benefit the world is the same. The prime minister benefits the world through Dao; the doctor benefits people through technique. I see many so-called doctors today testing drugs on patients and patients with drugs, rarely achieving perfect results. Only by chance does one succeed. Who can guarantee total efficacy? In the Gengxu year of Chunxi, I visited Lianshui and saw only one doctor, Chen Gong Wenxiu. Chen understood both adult and pediatric medicine, excelling particularly in childhood rashes. Officials and wealthy families in Lianshui, from Governor Xiao Xuanshi downwards, worried about severe illnesses. While other physicians stood helpless, Chen Gong remained calm, treating each case according to symptoms, achieving miraculous results. For poor villagers seeking urgent help, he did not refuse due to their poverty, rushing to save them, saving countless lives. For cases beyond sight or strength, he drew their appearances, distinguished symptoms, traced prescriptions, and had them printed to benefit future generations. Alas! Chen Gong's heart matches Fan Zhongyan's. Chen Gong, named Wenzhong, courtesy name Wenxiu, was from Fulí, Suzhou. After submitting to Song, he lived in Lianshui for fifteen years. Locals, known or unknown, called him "Magistrate Chen of Suzhou." In Yangzhou, where medicine flourished, his son studied literature but indulged in gambling, perhaps reaping what he sowed. I say: May you ponder this deeply. Praising his ancient-mindedness and precise medical choice, I recorded this at the end of the volume.

Self-Preface: I heard the ancient scholars say, "Heaven divides creation from one center; man initiates governance from the heart." Great is the heart! Is it not the pivot of all matters? Before past millennia, establishing heart for heaven and earth, and destiny for the people, was this heart. After future millennia, continuing lost learning for sages and transmitting teachings to successors, was also this heart. This heart, when used to save children, manifests true compassion. As the saying goes, seeing a child about to fall into a well evokes alarm and compassion in everyone; this stems from this heart. Dai Kechen (courtesy name Yaodao), Grand Hanlin Attendant and Imperial Physician in the Huizong reign, was a master of saving children, trusted in his time, and renowned in court and countryside. Heart transmitted to heart; only Liu Maoxian of Gaoyuan, Chengxi (name Si, pseudonym Guchong Shanyu), grasped its essence. Liu Maoxian's heart was inherited by his fifth-generation grandson, Zi Zhifu (name Sidao), who mastered it deeply. Applying his understanding yielded immediate results, revealing his dedication. However, ancient learning was transmitted via heart, but without books, the transmission could not expand. Since the Kaixi era, books have scattered, and the heart-transmission of Dai and Liu is nearly lost. Born after these two masters, I desired to resonate with their hearts. In my youth, I studied with Shi Yifu for years, receiving face-to-face instruction and heart-transmission, gaining much understanding. But considering medical books, prescriptions, theories, and poems, distant in time and disorganized in volumes, makes them hard to consult in emergencies. Alas! Those who grasp the heart dare not neglect investigating it. By bright windows in daylight and short lamps in rainy nights, I edited his遗留 works. Removing redundancy, supplementing deficiencies. Only recording usable books and effective prescriptions. Saving one part in a thousand, exploring the legacy of the Three Sovereigns and ancient sages above, and the intentions of Kechen and Maoxian below. This is the inherent principle of my heart, supplemented by contemporary brilliant physicians' theories, serving as an aid for saving children. Thus I named the book *Huoyou Xinshu*. Upon completion, a guest questioned me: "Medicine is intention. Observing form and pulse, guessing intentions, is sufficient. Why rely on books? And why name it 'Heart Book'?" I replied: "Not so. I do not intend to write to distinguish myself. I merely extend the true heart of the Liu lineage to align with Dai's original heart. Zhu Xi said: 'Intention is the emission of the heart.' Do not the books describe the flow and manifestation of the heart?" The guest withdrew in agreement. Thus written. In the Ju month of the Jiawu year of Zhixuan, Zeng Shirong Dexian, junior scholar from Yuxi, Hengyang, recorded this.
Preface by Hao Gangzhong: Humans receive the heart of heaven and earth that generates life. Thus, one should view heaven, earth, and all things as one body. Itches, pains, and illnesses are felt as one's own. This is the act of a benevolent person. Ancient scholars said physicians consider limb paralysis and numbness as "not benevolent" (bu ren). This phrase aptly describes "Ren" (Benevolence). When limbs are paralyzed, qi and pulses do not connect, pain and itch are not felt, and the life force of the heart ceases. How can one be benevolent? Especially regarding infants, whose speech is undeveloped and pulses unreliable, one must empathize with the heart to locate their pain and itch. Only those devoted to benevolence can achieve this. Zeng Dexian of Chengxi was a Confucian who became a physician. In youth, he learned Confucianism from local scholar Li Yueshan; in adulthood, he learned medicine from the hereditary Liu family. He studied medical classics carefully, tasted drug properties deeply, referenced profound discussions of predecessors, and asserted his unique views. He responded to all requests tirelessly, regardless of poverty. Collecting his usual diagnoses and prescriptions, he named it *Huoyou Xinshu*, intending to share it with like-minded individuals. Writing a book to express one's heart and spreading its transmission is the intention of a benevolent person. Observing his book, his diagnosis and prescription selection differed from others. Wu Ling San (Poria Decoction) was typically used by others for cold damage, damp-warmth, summerheat toxicity, and cholera. However, Dexian used it throughout the four seasons for convulsions, phlegm-choking, and rashes. Hu Shengzhai, Former Deputy Prefect of Hengzhou, asked after his son recovered from convulsions using Wu Ling San: "How did Wu Ling San cure this disease?" Dexian replied: "Fuling (Poria) calms the spirit of the heart; Zexia (Alisma) guides urination, benefiting the small intestine and connecting heart qi; Guizhi (Cinnamon Twig) suppresses liver qi, stopping wind naturally. Hence it treats convulsions. It has explanations for other conditions too." Shengzhai agreed deeply. This shows his adept use of Wu Ling San. Physicians often view infant convulsions as a single disease, administering minerals, borneol, musk, centipede, silkworm, snake, and scorpion agents, which are not only ineffective but may provoke other conditions. Dexian stated there are convulsions due to fright and those due to qi stagnation. Fright belongs to the heart, wind to the liver, but qi stagnation also causes convulsions. This aligns with Chen's statement that "accumulated qi forms convulsions." No specific prescription was given. For convulsions, I treat according to symptoms. If due to qi stagnation...
