Gossip originated in China and has a history of thousands of years. Eight trigrams are usually used in orientation, divination, geomantic omen and other disciplines. Moreover, it is said that the subject that can give full play to gossip is plum blossom easy counting. When it comes to calculation, it has nothing to do with science, and more people say it is superstition. To be exact, five lines of gossip is an academic. In fact, Chinese medicine in China sometimes uses five lines of gossip, and the five symbols of "wood fire, earth and golden water" respectively represent the five systems led by "liver, heart, spleen, lung and kidney".
It's like religion has been around for more than two thousand years. What are the reasons why so many people still believe in religion? Do you think religion belongs to science? What would it be like if a person had no religious belief?
I can only say: maybe the frontier of science and technology will return to its original state.
If this answer doesn't satisfy you, I suggest you study Feng Shui, which will take you into this academic field. I think you will know for yourself whether this is science or superstition.
