How to treat metaphysics such as Zhouyi, Five Elements, Eight Diagrams, Yin and Yang?

Philosophy: Science is concrete and philosophy is abstract. In ancient times, philosophy was all-encompassing, but with the deepening of research, various sciences gradually separated from philosophy and became an independent discipline. Up to now, it seems that only philosophy of life and philosophy of value belong to philosophy. The relationship between science and philosophy: Although science has been differentiated from philosophy, science still needs the guidance of philosophy in its research direction, and scientific research conclusions and achievements in turn supplement and revise philosophy. Therefore, they are in a relationship of mutual interference, mutual promotion and mutual supplement. Metaphysics: Metaphysics is very close to the concepts of Yi Xue, Shu Mathematics and Metaphysics. Metaphysics originally refers to metaphysics in Wei and Jin Dynasties, but modern folks use it to refer to more metaphysical learning such as eight-character technique, geomantic omen, physiognomy, and Wei Zi's doodling. Yi-ology refers to all kinds of academic knowledge based on the Book of Changes, such as divination, geomantic omen, Taoism and so on. The word "Shu Shu" first appeared in Huangdi Neijing, and Han Shu-Literature and Art Annals included astronomy, genealogy, five elements, turtles, miscellaneous trades and forms in Shu Shu.

The China Dictionary of Alchemy published in 1990s contains astrology, divination, Liu Ren, Daoism, fate, word classification, classes, scenery exploration, date selection and so on. Metaphysics is a huge academic system based on the theory of yin and yang and the theory of five elements, with the premise of philosophical concepts such as the isomorphism between man and nature, which has been formed through the long-term practice and application of countless people. In addition to the philosophical origin, metaphysics may have some mysterious sources (such as the intuitive understanding of the universe by ancient sages), such as the theory of meridians and acupoints in traditional Chinese medicine, which cannot be traced back today. Metaphysics books are often classified as philosophy in bookstores and libraries, and many people also think that metaphysics belongs to the category of applied philosophy. But since metaphysics has its unique research methods and research objects, it should be independent from philosophy.
