Is there really a fairy in the world? Fortune telling or something.

There are no immortals in the world, but fortune telling and gossip are well-founded. The Book of Changes itself is a divination book, but it is indeed a science, and every word in the book is derived from five lines of gossip. Can't say it's superstition. If it is superstition, many universities will not offer this course. China's knowledge of five lines of gossip is a world-class heritage. Hope to adopt!
