Is fortune telling accurate? There's a fortune teller on the internet, which is invalid?

Those who are online can't, and those who are not online are the smartest. Fortune-telling books are folk magic things, which were the most popular in ancient times. At that time, any capable fortune teller needed to pass it on by himself. It all depended on his real ability, and others would know it without passing it on himself. If you really want to tell fortune, you can only ask sincerely, and online fortune tellers are doing publicity.
