Introduction to fortune telling

In Harry Potter, hermione granger seems to disdain tricks such as reading tea leaves and staring into a crystal ball, but she is a faithful believer in digital fortune telling. Digital fortune-telling is a fortune-telling method based on numbers and names, and it is also one of Hermione's favorite subjects in the magic school. This prediction of the future is not based on the interpretation of fuzzy images, nor is it just to summarize the internal meaning of things from random graphics or scribbled words. On the contrary, digital fortune telling is based on a series of rules and strict numerical operations, and this kind of thinking happens to be Hermione's best and favorite job.
