保养您的形体，不要耗损您的精气，这样就可以长寿。这句话确实可以作为虚劳病调养的良方。我观察世间之人，患虚劳病的，十个人中常有六七个，然而一百人中难得保全一个的，是因为病人治疗得不早，医生治疗得不善。我年轻时得了这种病，调养了二十多年，至今安然无恙，可见此病并非不可治愈。只是我每次谈论此病，都痛心且担忧，所以特别阐明导致阴虚成病的成因，其次指出医书中混乱列举的问题，进一步推究真阴容易亏损的原因，以及各种症状标本传变乘袭的关系，还有误治的危害，最后以治疗要点作为开头，其主旨意图就是这样，不敢矫正当世的偏见，实在是基于先哲的经验加以阐发，我又亲身经历且验证无误，所以坦诚相告，希望医生和病人，都能反复研读这篇文字。
Nourish your physical form and do not dissipate your Jing (Essence), thus you can attain longevity. This statement is indeed an excellent method for the regulation and care of Xu Lao (Deficiency Consumption). I observe that among people in the world, six or seven out of ten suffer from Xu Lao (Deficiency Consumption); yet, among a hundred, it is rare to find one who remains healthy. This is because patients seek treatment too late, and physicians treat improperly. In my youth, I contracted this illness; after regulating and nourishing myself for over twenty years, I remain unharmed to this day. This demonstrates that this disease is certainly curable. However, whenever I discuss this condition, I feel deep pain and worry. Therefore, I specifically elucidate the causes leading to Yin Deficiency pathology, then address the chaotic categorization found in medical texts, further explore the reasons why True Yin is prone to deficiency, as well as the transmission and multiplication of symptoms regarding their root and branch aspects, and the detrimental effects of misdiagnosis and mistreatment. I begin with the essentials of treatment. The purport of this work is thus: I dare not merely correct the biases of the contemporary era, but rather aim to expound upon the experiences of ancient sages, which I have personally experienced and verified without error. Thus, I share my sincere thoughts, hoping that both physicians and patients will repeatedly reflect upon this chapter.
