This book is a lecture integration of Huangdi Neijing, a classic of traditional Chinese medicine taught by Mr. Nan in Taihu University Hall in 2007, focusing on the spirit of Neijing and the basic viewpoints of traditional Chinese medicine, so as to carry out research. Teacher Nan combined life science, Taoist health preserving theory with China traditional culture, quoted a large number of life examples, and vividly and clearly explained the subtle meaning and incomprehensible meaning of Neijing. The exquisite Huangdi Neijing, an ideological work containing the source of modern Chinese medicine and China's philosophy of life, has really entered the general public, become a daily life that everyone can touch and practice, and become a real "Bible" for China people to nourish their hearts, raise their sexuality and preserve their health. The published version is based on the traditional Chinese version of Taipei Old Ancient Culture Enterprise Company in 2008, and retains the characteristics of colloquial and life-oriented speech records. Mr. nan huaijin's repeated explanations and emphasis on some viewpoints and examples are out of the need of clarifying the theme and fairness. He has repeatedly explained that this is really "small talk", and there are many "unknown words" and "endless words", which I believe readers can understand.
