携李殷仲春顿首序
医学自从轩辕黄帝与岐伯重视民生以来，便通过谆谆的问答，贯通天地变化的规律，洞察阴阳运行的道理，其内容比之《尚书》中的典谟更为深奥穷尽，其态度如此慎重。因此，精通此道的人，从周朝历经汉、晋、唐、宋、金、元各代，值得效法的著作不过几十家，各家也各有长处，可见此道的难处又如此之大。然而，禀赋上等资质却不得到源流师承的人，最终也会鲁莽行事。从前扁鹊从长桑君那里得到禁方，太仓公（淳于意）从阳庆那里学到奇异的诊法，葛洪从郑隐那里继承秘术，孙思邈从龙宫那里得到仙法，李东垣（元素）梦中接受李明之的正统传承，朱丹溪拜罗太无为师扫地入门，王光庵从戴元礼那里开启医门钥匙，所以吴中地区的中医流派，得到了正统的脉络。
宇泰先生（指殷仲春或其所推崇者，此处指作者序言对象）在翰林院声名远播，广泛综览经史典籍，年少时喜爱医书，从《素问》、《难经》、《金匮要略》、《针灸甲乙经》等经典，下到诸子百家，无不精深探求其中的奥秘。他在自叙中说：“我起初头发干燥（指早年经历或身体状况），仰慕范文正公（范仲淹）存心济世救物的精神，立志非常迫切。”携李孝廉谦所先生与先生是同一年考中的举人，彼此情投意合。谦所先生是蜃川简肃公（沈一贯之子沈希诏等，此处指籍贯背景）的次子，才华横溢，气度宏大，敦厚喜爱奇书。得到先生的医论后，想要广泛救济天下人，不把医术秘密藏在帐幕之中。每次命令那些英才辈出的人刊印出版，都因故未及完成。
宇泰先生曾经说：“吴中地区自从王光庵得到戴元礼的秘传，再传给启东各位贤能之士，医道大为振兴。”又说：“《丹溪纂要》等书，并非朱丹溪亲笔所写，选择编纂有误，于是命令高生访求朱氏原本重新修订，技艺精湛，运用自如，没有不达到妙境的。”这本书就像江海的波澜，山岳的岭峰，船只的帆樯，军营的旗帜。作为证治各类书籍的选录，怎么可以忽视呢？又阅览先生关于发热的论述说：“《灵枢》、《素问》、《针灸甲乙经》等书中，发热的针刺方法非常高妙，世俗医生很少知道如何取用。其中五脏补泻的经络原理，用药可以替代。我想逐一制定方剂，但恐怕会局限后人的眼界，由此可知先生的圆融神妙，又超越了前人。”
携李殷仲春 顿首 序
Medicine, since Xuanyuan (Yellow Emperor) and Qibo emphasized the livelihood of the people, has engaged in earnest dialogues to comprehend the transformations of Heaven and Earth and penetrate the principles of Yin and Yang. Its depth surpasses even the *Dianmo* (Canonical Documents) of the *Shangshu* (Book of Documents), being thoroughly exhaustive, demonstrating such caution and solemnity. Therefore, those who have mastered this path, from the Zhou dynasty through Han, Jin, Tang, Song, Jin, and Yuan dynasties, have produced no more than a few dozen works worthy of emulation. Each school has its own strengths, highlighting again the difficulty of this discipline. However, those endowed with superior aptitude but lacking proper lineage and transmission ultimately act rashly. In ancient times, Bian Que received secret prescriptions from Chang Sang Jun; Taicui Gong (Chunyu Yi) learned miraculous diagnostic methods from Yang Qing; Ge Hong inherited secret arts from Zheng Yin; Sun Simiao obtained immortal methods from the Dragon Palace; Li Dongyuan (Ziwei) received the orthodox transmission of Li Mingzhi through a dream; Zhu Danxi entered the door of Luo Taiwu as a humble disciple; Wang Guang'an unlocked the secrets of medicine under Dai Yuanli. Thus, the medical schools of Wuzhong inherited the authentic lineage.
Mr. Yutai enjoyed fame in the Hanlin Academy, extensively studied the Classics and History, and cherished medical texts since his youth. From the *Suwen* (Basic Questions), *Nanjing* (Classic of Difficult Issues), *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet), and *Jiuzhen Jiayi Jing* (Systematic Classic of Acupuncture and Moxibustion), down to the works of various philosophers, he probed their profound mysteries with precision. In his autobiography, he stated: "In my early days, when my hair began to dry [indicating early life or health condition], I admired Mr. Fan Wenzheng (Fan Zhongyan) for his intention to benefit the world, and my resolve was firm." Mr. Qiansuo, a *Xiaolian* (Filial and Incorrupt) scholar from XieLi, was a contemporary of Mr. Yutai and they shared a close bond. Mr. Qiansuo was the second son of Lord Jiansu of Shenchuan, possessing outstanding talent and magnanimous spirit, and he had a keen interest in rare books. Upon obtaining Mr. Yutai's medical treatises, he wished to disseminate them widely to benefit all within the seas, rather than keeping them secret. He repeatedly ordered talented individuals to publish them, though it remained unfulfilled for some time.
Mr. Yutai once remarked: "Since Wang Guang'an received the secrets of Dai Yuanli in WuZhong, and passed them on to subsequent sages in Qidong, the medical Dao flourished greatly." He also stated: "Works such as *Danxi Zuanyao* are not handwritten by Danxi himself; their selection is flawed. Therefore, I commissioned Gao Sheng to seek out the original manuscripts of the Zhu family and revise them anew. With skill like that of an experienced wheelwright, everything reached perfection." This book is like the waves of rivers and seas, the peaks of mountains, the sails and masts of boats, and the banners of fortifications. As a compilation of selections from various books on syndrome differentiation and treatment, how can it be neglected? Furthermore, reviewing Mr.'s discourse on fever: "The acupuncture methods for fever in the *Linghu*, *Suwen*, and *Jiuyuan Jiayi Jing* are exquisite, yet rarely understood by contemporary physicians. The meridians for tonifying and reducing the five Zang organs can be substituted by herbal medication. I intended to formulate prescriptions for each case, but feared limiting the vision of future practitioners. Thus, one can see that Mr.'s wisdom is round and divine, surpassing even previous achievements."
