Yin-Yang and Five Elements, in the eyes of modern people in China, seem to have the function of divination and fortune-telling, and this is its only function. If people know that Yin and Yang are regarded as the source of China's scholarship in the early academic and historical documents such as Zhuangzi Tianxia and Sima Tan Liuyao, Yin and Yang and the five elements have been in China culture for five or six thousand years, which is the most suitable key to interpret China's ancient science. Professor Xiao Hanming's new book "Yin and Yang: Dahua and Life", based on the reconstruction of the theory of Yin and Yang and Five Elements, shows us the history of the coexistence of Yin and Yang and Five Elements with China traditional culture, and the significance of thinking methods in the construction of traditional culture at all levels, which makes people confused about the various entanglements between traditional culture and Yin and Yang and Five Elements.

First, in a wide cultural background, this book highlights the Yin-Yang and Five Elements as the methodological characteristics of the ancients' understanding of the world. Yin-yang and Five Elements originated from early human nature worship. Since the Zhou Dynasty, the thought of "good destiny" and "matching heaven with virtue" dominated, and the five elements of Yin and Yang struggled out of the worship of nature and became the key for people to explain natural and social phenomena. During the Spring and Autumn Period and the Warring States Period, as a universal thinking framework, it gradually penetrated into all levels of traditional culture, and had a wide influence on many fields such as astronomy, calendar, meteorology, medicine, alchemy, architecture, politics, military affairs, ethics, history, literature and art, philosophy and so on in ancient China. The first three chapters of Xiao discuss the influence of sun worship on the origin of Yin-Yang theory, and trace back to the development process of the schema thinking mode of Yin-Yang and Five Elements in Book of Rites, Moon Order, Guanzi, Shang Shu Hong Fan and Yijing. Then it discusses the alchemy of Yin and Yang, military strategist, Taoism, Confucianism, traditional medicine and Taoism in eight chapters, revealing the relationship between meteorology and human body. The author studied the classics carefully, learned from others' strengths, and specialized in precision, and made a detailed investigation on the mode of action of the river map and five elements schema as a combination of yin-yang and five elements theory in traditional medical theory.
