The *Book of Rites* records: "If a physician has not practiced for three generations, do not take their medicine." Some say this means that if the medical knowledge is passed down from grandfather to grandson over generations, its efficacy will be evident after a long time. Others say it refers to the need to thoroughly read the "Three Dynasties" books attributed to the Yellow Emperor. I privately believe this is not difficult to understand. The so-called "three generations" must imply a predestined karmic connection. Why? The universe is vast, and there are countless practitioners of medicine. Some have reputations that fill the cities, wearing through iron gates (a metaphor for immense fame), yet they fail to grasp the essential principles and mysteries of medicine. Conversely, some physicians clearly understand the cun and chi pulses at the wrist, perceive the pulse qualities distinctly under their fingers, discuss diseases and prescribe formulas in accordance with ancient methods. Is this not due to past-life karma?
In my youth, I received little systematic instruction from a master; as I grew older, I enjoyed reading the *Neijing* (Classic of Internal Medicine), *Nanjing* (Classic of Difficult Issues), *Shanghan Lun* (Treatise on Cold Damage), *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet), *Qianjin Fang* (Prescriptions Worth a Thousand Gold), *Waitai Miyao* (Secret Essentials from the Outer Tower), as well as works by major masters from the Qin, Han, Wei, Tang, Song, Yuan, and Ming dynasties. I immersed myself in these texts, enduring ten cycles of winter furs and summer clothes (indicating many years), opening doors to insights and uncovering subtle meanings. However, I had no leisure to publish or practice publicly at that time. To acquire knowledge, I purchased fine editions and rare manuscripts from various sources. When encountering good teachers and beneficial friends, I studied them with great intent. Later, I met Mr. Li Mengzhou, who taught me acupuncture. His methods of tonification and sedation, following and opposing, waiting for qi, and retaining qi all corresponded with ancient texts such as the *Lingshu* (Spiritual Pivot) and *Jia Yi Jing* (A-B Classic). I carefully examined and pondered these teachings and made slight progress. Those who heard of this invited me to treat their illnesses. Why did I achieve significant effects upon first treatment? There are arrogant people in the world who mock me for being stuck in antiquity. I believe that those who work behind closed doors yet follow the correct track, or who deviate from ancient standards while showing off novelty, completely trust books without regard for reality, and use references to ancient authorities to shift blame are erroneous. Although I am not intelligent, I am always diligent and cautious, fearing failure by violating ancient standards. I dare not show off novelty to boast of my skills, nor dare I cite ancients to hasten slander. Alas! I have no family-secret prescriptions in my heart, and the "Three Dynasties" books of the Yellow Emperor cannot be deeply understood and brought out explicitly. Relying on such superficial causes, yet hoping to reach the lofty realms of the ancients, I can only collect essences and pick flowers, burning oil to continue reading by day (working tirelessly day and night), finding joy in this without fatigue. With compassion filling my heart, I cultivated diligently, packed my bags, and left home. From Ningbo to Hangzhou, three years passed swiftly. I gained empty fame, and requests for consultation followed closely. My accumulated drafts formed a volume. Like someone addicted to eating scabs (a metaphor for a peculiar obsession), I was mistakenly appreciated by gentlemen. I instructed the printers to engrave and publish this, offering my foolish views to inform future generations. Whether you criticize or blame me, I am unaware.
