《目经》一书，裘同母弟庭镜所编着也。庭镜甫成童，轩轩霞举，颖敏过人，老父特爱之，寝处与俱，逐事
提训，一一理会。比长，博涉古学。时老父 于酒，凡应酬笔墨皆弟出，爱益至，居尝语母大人曰∶鸡鸣一鞭裘
为先着矣，然承予之志，终镜也。否则，坠厥业逮裘，叨附诸生，老父寻 谢尘土。弟既文战不利，又当大事，
哀毁过情，双睛不利于用。乃放浪形骸，每花辰月夕，与二三知己，或扁舟，或名园，或溪桥山寺，随在有觥觞
具、丝竹具、茶具、文具，啸嗷其间，几不知有身世，家人亦莫测所往，已而博古为师，刀圭丹灶自作周旋，病
忽瘥，遂以儒易医，不复问制科事矣。近年游艺湖海，贫不较利，戴德者转相牵引，车马往来无虚日。虽一时声
施藉甚，而家私销耗不少，盖交游广则费用不赀，四体惰而百务莫给也。况弟年三十有四，子八人且抱孙耳，非
惜福养财，何以为燕贻谋。一日徐及先子之语，弟面热不自安，既而曰∶缓急人所时有，能使镜无内顾忧，有所
成就，眼前名不与若争也。明发结装，告母氏以服贾，自豫而吴，五载旋家，风仪言笑，前后判若两人。有顷，
出是书印可细绎， 中妙理，在古人未言与言过处，侧锋谐语随叙随断，又有所见，皆借题发挥其抱负，根柢既
积，见地自高，较诸坊本何啻霄壤。始悟畴昔怏怏而去者，盖以为今日地也。嗟夫！木槿夕死朝荣，士固不长贫
也，东方曼倩不云乎。弟有才如此而流落不偶，正天诱其衷，成兹学术，秘不授人，尽可世收其利。似裘 穷
年，徒读 书，未能出朋辈一头地，遑计身后名、眼前名耶。于以叹老父知子之明，
而嘉弟立志之远，更喜北堂爱日，母大人娱乐如初，谨陈巅末，以启嗣子之善承厥业而不坠，海内医家，知汲古
有识如庭镜，观摩砥砺，亦可奋然兴矣。
同怀兄冶子裘序
《目经》这部书，是由裘同母弟黄庭镜编写撰著的。黄庭镜刚成童（儿童），气度不凡，才华敏捷超过常人，老父亲特别喜爱他，起居生活都与他在一起，每件事都加以教导训诫，让他一一明白理解。等到长大成人后，广泛涉猎古代学问。当时老父亲嗜酒，凡是应酬往来、笔墨书写的事都由弟弟承担，宠爱更加深厚，平时常对母亲说：“大儿子（裘）在鸡鸣时便鞭策自己，是首先着手做事的人，然而继承我的志向的，终究是二儿子（镜）。否则，家业就会坠落到大儿子身上，使他侥幸成为诸生（秀才），老父亲不久也会谢世尘土。弟弟既然科举考试不利，又遭遇重大变故（指丧父），悲哀过度损伤身体，导致双眼视力受损无法使用。于是放纵形骸，每逢花好月圆之时，与两三位知心朋友，或乘小舟，或游名园，或访溪桥山寺，随处都有酒杯、乐器、茶具、文具，在其中长啸高歌，几乎忘记了自己的身世，家人也无法猜测他的去向。后来以博古通今为师，亲自研习医药炼丹之术，病情忽然痊愈，于是从儒学转向医学，不再过问科举功名之事了。近年来游学于湖海之间，贫穷却不计较利益，受恩德的人辗转互相推荐，车马往来没有一天空闲。虽然一时名声很大，但家中私产消耗不少，大概是因为交游广阔则费用巨大，四肢懒惰而各种事务无法供给。况且弟弟已经三十四岁，有八个儿子甚至抱孙子了，如果不珍惜福气、积蓄钱财，拿什么来做长远打算呢？有一天徐及先提到父亲的话，弟弟脸红感到不安，随后说：“急缓是人时常遇到的，如果能使我没有后顾之忧，有所成就，眼前的名声就不必和哥哥争了。”第二天清晨整理行装，告诉母亲要去经商，从河南到江苏，五年后回家，风度仪容言谈笑语，前后判若两人。过了一会儿，拿出这本书请人审阅认可，细细研读其中妙理，在于古人未说到的和说过头的地方，侧锋诙谐的话语随叙随断，又有新的见解，都是借题目发挥抱负，根基既已积累，见识自然高远，比起市面上的版本何止是天壤之别。这才明白过去郁郁寡欢离去的原因，大概是认为今天是这样的境地。唉！木槿花晚上死早上开，读书人本来就不会长期贫困，东方朔不是说过吗。弟弟有如此才华却流落不遇，正是上天诱导其内心，成就这门学术，秘密不传授给别人，完全可以世代收取其利。像大儿子那样穷尽一年，徒然读书，未能超出同辈一头，哪里还顾得上身后的名声、眼前的名声呢。因此感叹老父亲知子之明，嘉奖弟弟立志之远，更高兴北堂（指母亲）爱日（孝养母亲），母亲大人娱乐如旧，谨陈述始末，以启发嗣子善于继承家业而不坠落，让海内医家知道汲古有识见如黄庭镜者，观摩砥砺，也可以奋发兴起。
同胞兄长冶子裘序
The book *Mu Jing* (Classic of the Eyes) was compiled and authored by Huang Tingjing, younger brother of Qiu Tongmu. When Tingjing was just a child, he possessed an extraordinary demeanor and his brilliance and agility surpassed others. His father loved him dearly, sharing daily life with him and instructing him in all matters so that he could understand them thoroughly. Upon reaching adulthood, he extensively studied ancient learning. At that time, his father had a fondness for wine, and all social correspondence and writing tasks were handled by the younger brother, leading to even greater affection. The father often told the mother, "Our eldest son (Qiu) starts his work at cockcrow and is the first to act, but it is ultimately our second son (Jing) who will inherit my aspirations. Otherwise, the family profession would fall to Qiu, allowing him to barely qualify as a Shengyuan (licentiate), and I would soon pass away into dust." After failing in the civil service examinations and facing major bereavement, Tingjing grieved excessively, damaging his health and impairing his vision. He then adopted a free-spirited lifestyle, spending times of flowers and moonlight with two or three close friends, sometimes in small boats, famous gardens, or mountain temples by streams. Everywhere they went, there were wine cups, musical instruments, tea sets, and writing tools, amidst which he would howl and sing, almost forgetting his worldly existence; his family could not guess his whereabouts. Later, he took erudition as his teacher and personally engaged in the practice of medicine and alchemy. His illness suddenly healed, and he switched from Confucianism to medicine, no longer concerning himself with imperial examinations. In recent years, he traveled widely across lakes and seas, poor but indifferent to profit. Those indebted to his virtue introduced him to one another, and carriages and horses visited without a day's rest. Although his reputation was great for a time, his private wealth was significantly depleted, largely because extensive socializing incurred huge expenses, while his indolence made it difficult to manage various affairs. Moreover, at thirty-four years old, with eight sons and even grandchildren, if he did not cherish fortune and conserve wealth, how could he plan for posterity? One day, when Xu Ji mentioned his father's words, Tingjing blushed and felt uneasy, but then said, "Adversity and ease are common occurrences. If this allows me to have no internal worries and achieve something, I need not compete with [my brother] for present fame." The next morning, he packed up, informed his mother of his intention to engage in commerce, traveling from Henan to Jiangsu, and returned home five years later. His demeanor, appearance, speech, and laughter were completely different from before. Soon after, he presented this book for review and approval. Careful study reveals its subtle principles lie in what ancients omitted or overemphasized. With witty remarks interspersed in the narrative and new insights expressed through thematic elaboration, his deep foundation naturally elevated his perspective, making this work vastly superior to commercial editions—like heaven and earth apart. It became clear that his previous melancholy departure was due to anticipating this very situation. Alas! The hibiscus blooms in the morning and dies in the evening; scholars do not remain poor forever. Did not Dongfang Shuo say so? Having such talent yet remaining unrecognized is precisely Heaven guiding his inner heart to perfect this academic pursuit. Keeping it secret and not teaching it to others allows his descendants to reap benefits for generations. Like the eldest son, who reads books all year round in poverty without surpassing his peers, let alone worrying about posthumous or present fame. Thus, we sigh at the father's wisdom in knowing his son, commend the brother's far-reaching ambition, and rejoice that the mother (symbolized by the North Hall) enjoys filial piety and happiness as before. I respectfully state these details to inspire the heir to inherit the profession well and not let it fall into decline, and to inform physicians within the seas that there is one like Tingjing who draws from antiquity with insight. Through observation and mutual encouragement, they too may be inspired to rise.
