黄不尘，是我明经科考试的同学兼后辈。他天资聪慧灵敏，博学多才。他所作的诗歌和古文辞藻不落俗套，自成一家风格。此前他有《抒愫居存草》诗集流传，见到的人每每为之击节赞赏，由此可以想见他的为人。奇怪的是他不从事八股文（科举应试文章）这一道学问，而是侍奉他人并展示作品请人指出优缺点加以嘱咐，然而似乎不屑于听从这些建议。我曾严厉责备他说：追求功名却不致力于此道，这就像向南走而车辙却向北一样啊。
后来我们因分离而疏远，与黄子日渐生疏。当时我正想着通过八股文考取功名来求取知遇，后悔把诗歌、古文当作累赘，没想到他却抛弃了经史之学去钻研岐黄之术（医学），改变了好古之心转而喜好医术，这也已经很久了。凭借黄子的才华，是我们同辈中一向推崇佩服的，如果他能好好修养身心，那么立德立功并非难事，像我这样平庸之人，是追不上他的背影的。可惜他不爱惜自己，甘心降低志向混迹于眼科之中，可悲啊！
此后他游历名胜古迹，颇负盛名，我私下怀疑他是靠聪明才智欺世盗名，倒也不觉得奇怪。恰逢我生病，性命垂危，遇到他治疗而痊愈。于是问他究竟有什么神秘之处能奏效如此神速，黄子迟疑地推辞说并不敏捷，从箱子里拿出《目经》三卷给我看，我读后感叹道：不尘子用心于这门技艺，竟然精妙到这种地步！我不懂医学，但觉得他阐述医理源流透彻，好像不仅仅是为专门研究眼科而设。而且他用很少的比喻就能痛快论述，令人惊心解颐，又好像让人忘记这是医书一样，知道这不是为了打破常规以耸动观览，实在是不失好古的本色。
这部集子出版后，定能使《抒愫居存草》先于其他著作流传不朽，这与那些揣摩八股文到老死窗下而湮没无闻的人相比，相差何其悬殊。黄子真有卓见，只是不为自爱罢了。唉！上天赋予黄子如镜子般明亮的智慧，化成重离（指光明、眼睛）之书，将照耀天下后世，使盲人赖以不再盲目；而那些昏庸不知学习的人，或许把它等同于寻常的方脉书籍，甚至想要在其中诋毁议论，他们这种盲目，即使是黄子也没有办法救治了。

Huang Buchen is a fellow student and junior colleague of mine from the Mingjing (Classics) examination. He possessed a natural disposition that was agile and spirited, being erudite and versatile. His poetry and classical prose did not fall into clichés, establishing his own unique school. Previously, he had a collection titled *Shusu Ju Cuncao* (Manuscripts from Shusu Residence), which those who saw it would often applaud with rhythmic beats, allowing one to imagine his character. It is strange that he neglected the path of Bagu (Eight-Legged Essay, for imperial examinations), instead serving others and presenting works for critique, yet seemed disdainful of listening to advice. I once severely reprimanded him, saying: "Seeking fame without attending to this is like driving south while the wheels roll north."
Later, due to separation, we grew distant from Huang. At that time, I was contemplating passing the Bagu examination to seek recognition, regretting that poetry and classical prose were burdens, unaware that he had abandoned the study of Classics and History to delve into Qihuang (Traditional Chinese Medicine), changing his love for antiquity to a love for medical arts, which had been going on for quite some time. With Huang's talent, which our peer group always admired and respected, if he had cultivated himself well, achieving virtue and merit would have been no different from ordinary people; someone mediocre like me could never catch up with his dust. Alas, he did not cherish himself, willingly lowering his aspirations to mingle in the field of ophthalmology. How sad!
Thereafter, he traveled to famous scenic spots and gained considerable reputation. I privately suspected he was deceiving people with his cleverness, which was not unusual. When I fell ill and my life was nearly lost, I encountered his treatment and recovered. I then asked him what mystery allowed such efficacy. Huang hesitatedly declined credit, saying he was not particularly quick-witted, and took out three volumes of *Mu Jing* (Classic of the Eye) from a chest. After reading it, I sighed and said: "Buchen has devoted his mind to this art, reaching such a level of precision!" Although I do not understand medicine, I felt that his explanation of the origins and details of medical principles was thorough, as if not merely set up for specialized ophthalmology. Moreover, his rare metaphors and lucid arguments were startling and delightful, making one forget it was a medical book. I realized this was not done to break conventions for shock value, but truly retained his original love for antiquity.
With the publication of this collection, *Shusu Ju Cuncao* will surely be transmitted immortally first, compared to those who pore over Bagu essays until death under their windows, remaining obscure and unrecorded—the difference is vast. Huang indeed has outstanding insight, yet fails to cherish himself. Alas! Heaven endowed Buchen with a mirror-like clarity, transforming it into a book of Chongli (Double Li, symbolizing brightness/eyes), which will illuminate the world for generations to come, enabling the blind to see. Those who are ignorant and refuse to learn may treat it as an ordinary pulse diagnosis manual, even daring to criticize it within its pages. Their blindness, however, is such that even Huang has no remedy to cure them.
