The Huangdi Neijing serves as the fundamental and foundational theory for various disciplines in Chinese medicine, including physiology, pathology, acupuncture and moxibustion, and more. It is indispensable for anyone aspiring to master the realm of Chinese medicine. Even though later generations have expanded upon it, their work is inevitably rooted in this text. Just as classical physics is grounded in Newton's (1643–1727) three laws, which have been applied for centuries, and even though quantum mechanics and relativity have since emerged, they cannot replace it. However, since the chapters of this book were largely completed during the Spring and Autumn, Warring States, Qin, and Han periods, the language is archaic, and there are occasional missing sections. The content also encompasses ancient knowledge of astronomy, geography, meteorology, society, politics, mathematics, craftsmanship, and more. Without extensive study of both ancient and modern disciplines, it is difficult to fully grasp its essence.

The same book, if read with a dismissive mindset, will seem incomprehensible at every turn; if read with humility and a thirst for knowledge, it will reveal its wisdom at every step.
