水银之走者，此也。是症不多见，针亦莫能奏效，学人识之。

目瞽既久，生犹死也。一旦复见人世，纵需用多金，当亦乐从。况有不爱钱，肯施恩之天医乎！乃以下九辈
视为容易，不惟不谢承，翻埋冤赖诈，是盖蛇蝎蚁蛆合为一体，豕心狗行，未足方其秽恶。览者不怒发冲冠，决

水银（Mercurius）在体内游走的情况，就是这样的。这种病症并不常见，针刺也无法取得疗效，学习中医的人应当知晓这一点。

眼睛失明已久，活着如同死去一般。一旦重新看见人世，即使需要花费大量金钱，患者也应当乐意接受。更何况还有那些不爱钱财、愿意施恩的“天医”呢！然而下面这九个人却把治病看得很容易，不仅不感谢恩人，反而诬陷、怨恨、欺诈，这简直是蛇蝎、蚂蚁、蛆虫合为一体，猪的心肠、狗的行为，不足以形容其肮脏恶劣。阅读这些案例如果不让人怒发冲冠，决不是刚烈之士。
邵武人罗东山，是书办罗英抚养的儿子。三十岁时，家境极其贫寒。听说吴某被休弃的妻子张氏，回娘家居住。岳母家颇有积蓄，足以维持粗茶淡饭的生活，罗东山便通过关系入赘张家。然而妻子年老且无子嗣，心中敢怒而不敢言，视力逐渐丧失直至失明。当时提学葛某进行岁试，罗东山扶着盲人去验身。家里的弟弟和侄子见到他后，教唆他去拜访余某（作者自称）。余某的朋友艾南天，曾经寄宿在张家。罗英贪图艾南天有钱，让罗东山像对待父亲一样侍奉艾南天，到了这时，罗英又依靠艾南天极力请求治疗。所有的费用都由艾家提供。药费赠送给艾南天的哥哥艾秀瞻。大概是怜悯罗东山的贫穷和疾病，并且乐于促成此事。没想到两目经过针刺治疗后重见光明，艾家却坚决隐瞒不承认。反而说眼睛黑痛痛苦，日夜哭泣嚎叫。艾母怀疑他是饥饿或受寒，时常派人给予施舍。但他哭泣更加频繁，嚎叫更加嚣张。我直接呵斥也不能禁止，于是谋划将他抬回去。第二年春天，艾秀瞻的侄子廷珍考中秀才，因为同窗告知近况，才知道他已经具呈参加补考，又过了一年艾南天去世。艾母八十岁寿辰，艾家竟然没有一个字来问候。不论是否应该不忘恩情，即使是泛泛之交，也没有这样不通人情理的。
我既然精通针法，焚香告天，希望有能治愈的病人，不问贫贱，都给予医药治疗。丰人饶倒，生来就患有银星内障，父母感到惊异，爱怜超过平常
The migration of Mercurius (Shuiyin) within the body is as described above. This condition is not common, and acupuncture cannot achieve efficacy; students of medicine should be aware of this.
Appendix: Nine Medical Cases
Having been blind for a long time, one is alive yet dead. Once seeing the human world again, even if much gold is required, one should willingly comply. Moreover, there are "Heavenly Doctors" who do not love money and are willing to bestow grace! However, the following nine generations regarded it as easy, not only failing to show gratitude but also framing, harboring resentment, and committing fraud. They are like snakes, scorpions, ants, and maggots combined into one body, with the heart of a pig and the conduct of a dog, insufficient to describe their filth and evil. Those who read this and do not have their hair stand on end in anger are certainly not men of integrity.
Luo Dongshan from Shaowu was the son raised by Luo Ying, a clerk. At thirty years old, he was extremely poor. He heard that Zhang, the wife abandoned by Wu, had returned to her mother's home. Her mother had some savings, sufficient for coarse porridge and pickles. Through connections, Luo Dongshan became a matrilocal husband (ruzhui). However, the wife was old and childless, daring to be angry but not speaking out, her vision gradually faded until she went blind. At that time, Ge, the Provincial Education Commissioner, conducted the annual examination. Luo Dongshan, supporting a blind person, went for verification. His younger brother and nephews saw him and advised him to visit Yu (the author). Yu's friend, Ai Nantian, had once stayed at Yi Fang's residence. Luo Ying, coveting Ai Nantian's wealth, ordered Dongshan to treat him like a father. Now, relying on Ai Nantian, he sought treatment vigorously. All expenses were covered by them. The cost of medicine was gifted to Ai Xiuzhan, Ai Nantian's elder brother, likely out of pity for his poverty and illness, and willingness to assist. Unexpectedly, after both eyes regained sight through acupuncture, they firmly denied it. Instead, citing blackness and pain, they wailed day and night. Mother Ai suspected hunger or cold, frequently sending provisions. Yet his crying became more frequent and wailing louder. I directly scolded but could not stop him, so we planned to carry him back. In the spring of the next year, Tingzhen, the nephew of Brother Xiu, passed the examination to become a student member (shengyuan). Through peers' words about recent circumstances, it was known that he had submitted a petition for supplementary examination. The year after that, Ai Nantian died. For Mother Ai's eightieth birthday, there was not a single word of inquiry. Regardless of whether one should not forget kindness received, even among casual acquaintances, such inhumanity does not exist.
Since I am proficient in acupuncture, I burned incense and prayed to Heaven, wishing that anyone curable, regardless of poverty or nobility, would receive medical treatment. Feng Renraodao was born with Silver Star Cataract (Yinxing Neizhang); his parents were astonished, loving him more than usual.
