Although the Book of Changes is extensive and profound, and the traditional Yin-Yang and Five Elements are reasonable, this product of wisdom in China culture is still a quasi-science, and its theory has not been fully confirmed. The five-grid dissection method based on "image" and "number" in Zhouyi seems to have its "scientific" basis. Although its explanation is fluent and ambiguous, it is actually just a perceptual thing like a fortune teller's face reading. So, think of it as a word game and don't believe it.
