How credible is folk fortune telling?

There is 70% reliability. Although fortune-telling is not allowed in mainstream culture now, it is after all the experience summed up by our ancestors for thousands of years. Although China didn't attach importance to scientific research before, his summing up experience is absolutely the best. Now some people have explained quite a few fortune-telling methods in scientific language.

Tell a real example: when I came home for the Spring Festival last year, my grandfather showed me a book about astrology, and actually predicted that there would be a big earthquake in 2008 and a wise master.

As for the other 30%, it's mysterious and mysterious, as if it were imaginary and unbelievable.
