尝稽古今医学，备悉万病，独不明痧，因而人鲜其传，无奈世之患者比比也。既有此病，不可不求有以治之。余因
以治之所验，悉其症之所由。于甲寅岁着《玉衡》一书，偕同人互相参订，急而行之，亦济生之念所不得已也。书中凡
叙痧说，似已具详，两年来痧之变幻，更有隐伏于别病中者，伤人最多，非为世所罕识。尤余前书之所未及，因又有痧
刻之续。凡以因时所犯，略采异验为集，夫亦谋诸同人，非敢以自矜也，幸天下不以多赘而忽诸。

──言有不实，治有不效者，一句不载。
──药有不当，用有不明者，一味不入。
──据症用治，立方制宜，非痧不录。
──按脉阅筋，恐人有误，详之有据。
──砭刺痧筋，必须紫黑毒血，据为实见。
──载杂症，仅取兼痧，诸病虚实，悉在所略。
──心腹痧痛，刮放即愈。不烦医药者，不重加载。
──治验不过一二三四，惟略见治法为准，余不多赘。
──余近地气禀柔弱，故方中分两，从乎减少，便能取效。此虽传示四方，不敢多加。
──制方分两甚少，若遇西北，风高土燥之地，刚强勇壮之人，其分两必须加倍，或加二倍三倍，方能有效。

I have examined medical literature from ancient and modern times, thoroughly understanding myriad diseases, yet the condition of Sha (a traditional Chinese disease concept often associated with heat-toxin or stagnation) remained unclear. Consequently, its transmission was rare, despite the fact that patients suffering from it were ubiquitous in society. Since this disease exists, one cannot but seek a method to treat it. Therefore, I recorded all the therapeutic methods I had verified as effective, along with the etiology of the symptoms. In the year of Jiayin, I authored the book *Yuheng* (Jade Balance), which was reviewed and revised together with my colleagues. It was published hastily, driven by an unavoidable compassion for saving lives. The discussions on Sha theory within the book seemed quite detailed; however, over the past two years, the变幻 (changes/variations) of Sha have become more complex, with some cases lying latent within other diseases, causing the most harm. These are not unfamiliar to the world, nor were they covered in my previous work. Hence, *Shake* (Sha Carvings/Notes) was produced as a sequel. This collection primarily compiles unique therapeutic experiences based on contemporary afflictions. It was discussed with colleagues, and I dare not boast of it. I hope the world will not overlook it due to its length.

── If any statement is untrue or any treatment ineffective, not a single word is recorded.
── If any herb is inappropriate or its usage unclear, not a single ingredient is included.
── Treatments are prescribed according to symptoms, and formulas are formulated appropriately; non-Sha conditions are not recorded.
── Pulse diagnosis and observation of sinews are described in detail with evidence to prevent misinterpretation.
── For scarification of Sha sinews, only purple-black toxic blood is documented as empirical evidence.
── Miscellaneous diseases are recorded only when accompanied by Sha; the deficiency or excess of other diseases is omitted.
── Cases of abdominal Sha pain cured immediately by scraping or bloodletting, requiring no further medication, are not heavily emphasized.
── Therapeutic validations are limited to a few examples; only representative treatment methods are outlined, without excessive elaboration.
── As my constitution is naturally weak, the dosages in my formulas are reduced to achieve efficacy. Although shared widely, I dare not increase the dosages arbitrarily.
── The dosages in the formulas are small. However, in the northwest regions where the wind is high and the soil dry, for robust and vigorous individuals, the dosages must be doubled, or even tripled, to be effective.
