The first book is Shan Hai Jing, which is divided into Shan Hai Jing and Hai Jing. Among them, there are two differences in Hai Jing, one is Yesi Jing, and the other is Overseas Si Jing and Hai Si Jing. The Classic of Mountains and Seas records the treasures of ancient times, in which many fairy tales and exotic animals are recorded. This book has a great influence on later generations, but unfortunately, when it was circulated, all kinds of pictures of rare birds, animals and immortals disappeared, leaving only the text explanation part. Because the things recorded in it are so bizarre, experts say this book is not credible.
The second book is Huangdi Neijing, which was an influential book in ancient times. It is an early classic of Chinese medicine and one of the traditional medical books. This book discusses medicine from the perspectives of nature, biology, psychology and society as a whole. It is not only a book of keeping in good health, but also a hundred books about life and a theoretical book of traditional Chinese medicine. Huangdi Neijing not only has a far-reaching influence on Chinese medicine, but also becomes a must-read for western medicine researchers to learn Chinese medicine.
The third book is the Book of Changes. According to ancient legends, there are three books that can magically predict the future, one of which is the Book of Changes. The Book of Changes reveals the changing truth of the causal cycle of everything in the world in the form of hexagrams. This book contains profound natural laws and thoughts, and is the crystallization of the wisdom of the Chinese nation. It is precisely because the content is so magical and profound that no one can really understand the wisdom since the Qin and Han Dynasties. Of course, the Book of Changes can become a book because of its value. It's also our problem not to understand ourselves.
These three books are three wonderful books in ancient times and cultural treasures.
