Who is suitable for self-study fortune telling?

What kind of people are suitable for learning eight characters,

People are suitable for those who are interested in learning the eight characters, or those who are interested in the traditional culture of China. And you have to believe that you can measure people's good or bad, so anyone can learn, because this is a matter of personal interest. Whether you learn well or not is your own business. So I think anyone who is interested can learn Chinese characters.
