一、是编皆岐伯天师、仲景张使君所口授，铎敬述广推以传世。实遵师诲，非敢自矜出奇。
一、辨证不辨脉者，以证之易识也。苟能知症，何必辨脉哉。虽然，辨证更能辨脉，则治病
益精，又在人善用之耳。
一、辨论证候均出新裁，阐扬《灵》、《素》所未备，于二经不无小补云。
一、编中不讲经络穴道，以经络穴道之义，已显载于《灵》、《素》二经，人可读经自考也。
一、各门辨证，专讲五行生克之理，生中有克，克中有生，经权常变，颠倒纷纭，贵人善读
之耳。
一、铎壮游五岳，每逢异人传刀圭之书颇富，凡可引证，附载于各辨证条后，以备同人采择。
一、祖父素好方术，遗有家传秘本，凡关合各症者，尽行采入，以成异书。
一、吾越多隐君子，颇喜谈医，如蒋子羽、姚复庵、倪涵初、金子如、蔡焕然、朱瑞林诸先
生，暨内父张公噩仍与同辈余子道元、叶子正叔、林子巨源、钱子升 、丁子威如、家太士，或
闻其余论，或接其片言，均采入靡遗。
一、兹编不讲针灸，非轻之也。盖九针治病之法，已畅论于《灵》、《素》书中，不必再为
发明耳。
一、人病最多，集中所论，恐不足概世人之病，然生克之理既明，常变之法可悟，此编旁
通治法，正有余也。
一、二师所传诸方，与鄙人所采诸法，分两有太多过重之处，虽因病立方，各合机宜，然而气
禀有浓薄之分，生产有南北之异，宜临症加减，不可拘定方中，疑畏而不敢用也。
一、铎年过六旬，精神衰迈，二师传铎之言，愧难强记，恐至遣忘，辨论之处，或多未备，
尤望同人之教铎也。
一、是编方法，亲试者十之五，友朋亲串传诵者十之三，罔不立取奇验，故敢付梓告世。
然犹恐药有多寡、轻重，方有大小、奇偶，又将生平异传诸方，备载于
后，便世临病酌用也。
一、岐天师传书甚富，而《外经》一编尤奇。篇中秘奥，皆采之《外经》，精鉴居多，非无
本之学也。铎晚年尚欲笺释《外经》，以求正于大雅君子也。
一、铎勤着述，近年以来广搜医籍，又成一编，决寿夭之奇，阐生克之秘，有益于人命不浅。
怅卷帙浩繁，铎家贫不克灾梨，倘有同心好善之士，肯捐资剞劂，铎倾囊付之，不吝惜也。
大雅堂主人远公识
1. The contents of this compilation were orally instructed by the Heavenly Master Qibo and Lord Zhang Zhongjing. I respectfully recorded and expanded upon them to pass them down to posterity. This is truly in accordance with my teacher's teachings; I dare not boast of novelty or uniqueness.
2. In differentiation, this book does not emphasize pulse diagnosis because symptoms (Zheng) are easier to identify. If one can understand the symptoms, why must one differentiate the pulse? Nevertheless, if one can differentiate both symptoms and pulses, treatment will be more refined; it depends on how skillfully one applies these principles.
3. The differentiation of symptoms and signs in this book offers original insights, elucidating aspects not fully covered in the *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions). It may offer minor supplementation to these two classics.
4. This book does not discuss meridians and acupoints, as their principles are clearly documented in the *Ling Shu* and *Su Wen*. Readers may consult these classics for self-study.
5. Differentiation in each category focuses specifically on the principles of the Five Elements' generation and restriction. Generation contains restriction, and restriction contains generation; constancy and flexibility, routine and variation are complex and intertwined. It is hoped that readers will study them diligently.
6. In my youth, I traveled extensively across the Five Sacred Mountains. Whenever I encountered extraordinary individuals who transmitted medical texts, I collected a wealth of them. All citations applicable here are appended after each differentiation entry for peers to select from.
7. My grandfather was fond of medical arts and left behind secret family manuscripts. Any relevant to various conditions have been fully incorporated to form this unique work.
8. There are many reclusive scholars in my region (Yue) who enjoy discussing medicine, such as Mr. Jiang Ziyu, Yao Fuan, Ni Hanchu, Jin Ziru, Cai Huanran, Zhu Ruilin, as well as my father-in-law Mr. Zhang Eren, and contemporaries Yu Zidaoyuan, Ye Zhengshu, Lin Juyuan, Qian Sheng, Ding Weiru, and Jia Taishi. Whether through hearing their discussions or catching fragments of their words, all have been exhaustively recorded.
9. This book does not discuss acupuncture and moxibustion, not out of disdain. The methods of the Nine Needles are already thoroughly discussed in the *Ling Shu* and *Su Wen*, so no further elaboration is necessary.
10. Diseases are numerous; the cases discussed herein may not cover all illnesses of the world. However, once the principles of generation and restriction are clear, and the laws of constancy and change are understood, the supplementary therapeutic methods in this book are more than sufficient.
11. The dosages in the prescriptions transmitted by the two masters and the methods I collected are often excessive. Although prescribed according to specific pathologies and fitting the clinical situation, individual constitutional endowment varies in density and thinness, and geographical origins differ between North and South. Dosages should be adjusted according to the clinical presentation; one should not be bound by fixed formulas nor hesitate to use them due to doubt or fear.
12. Having passed sixty years of age, my spirit and vitality have declined. I find it difficult to strongly memorize the words transmitted by the two masters and fear forgetting them. Thus, the differentiations and discussions may be incomplete. I earnestly hope for guidance from my colleagues.
13. Five-tenths of the methods in this book were personally tested, and three-tenths were verified through transmission among friends and relatives. All yielded immediate miraculous effects, which is why I dared to have them printed and published. However, concerned about variations in herb quantities and weights, and differences in formula sizes and structures (odd/even), I have detailed other prescriptions acquired throughout my life at the end, for readers to酌情 (discretionarily) apply when treating diseases.
14. The Heavenly Master Qibo transmitted abundant texts, among which the *Wai Jing* (Outer Classic) is particularly remarkable. The secrets within its chapters are largely drawn from the *Wai Jing*, containing many profound insights; it is not scholarship without foundation. In my later years, I still intend to annotate the *Wai Jing* to seek correction from learned gentlemen.
15. I am diligent in writing. In recent years, having extensively searched medical literature, I have completed another compilation that determines longevity and premature death and elucidates the secrets of generation and restriction, offering significant benefit to human life. Regrettably, the volumes are vast, and my poverty prevents me from bearing the cost of printing (carving wooden blocks). If there are like-minded gentlemen who love kindness and are willing to donate funds for publication, I will contribute everything I have without hesitation.
