This book first discusses the general principles of health care, including the concept of "harmony between man and nature, four seasons of yin and yang", different health care laws in different seasons and periods, as well as the concept of healthy life and the theory of physical health care in Neijing; Furthermore, it discusses the method of "unity of form and spirit" in Neijing, focusing on the main methods of regulating spirit from inside and outside, including modern psychological conditioning methods, and introduces various physical exercise and qigong exercise methods in ancient and modern times, and discusses the psychological and sports conditioning laws of common diseases. Finally, it focuses on the principles of diet regimen in Neijing, including the basic principles and applications of diet regimen, and collects various representative dietotherapy prescriptions in ancient and modern times.

All his theories are based on Huangdi Neijing, which is close to previous dynasties, and are closely integrated with modern times. It has the characteristics of comprehensive discussion system, rich and colorful content, easy-to-understand language and practical methods. If readers can concentrate on their studies, it will be of great benefit to guide themselves or others to keep fit and prolong their lives.

Huangdi Neijing inherits the wisdom of Chinese health care and interprets the essence of health care for three thousand years. It is based on yin and yang, with harmonious skills, moderate diet and regular daily life.

It is a brand-new subject to expound the health-preserving thought and theory of Huangdi Neijing, and our editorial colleagues have taken this brand-new step through hard work. Because this is a new exploration and attempt, there may be some imperfections and inaccuracies in some places. I very much hope that readers and peers will criticize and correct me so that we can make corrections when reprinting and make more beneficial contributions to the cause of human health.
