I can't understand, where did those divination and astrology come from? Feudal superstition or human subconscious calculation?

I don't know much about this. I only know that tarot cards are a way of group suggestion and emotional calculation. Tarot cards in the west are mainly a kind of divination similar to games, mostly seeking a little comfort and a good psychological hint when people are confused.

Astrology is under the rules stipulated by predecessors, people judge people's good or bad according to the changes of various constellations given by experience.

Palmistry is an experience summed up by ancient people in China. I'm not sure about the principle, but it seems accurate. If you look closely, you will find that people's palms will change. In addition to wisdom, this is also judged according to the regulations of the ancients.

I don't know much, I hope to explore.
