The reason why fortune telling is not allowed is that fortune telling is not allowed at all.

It is superstition to call bones fortune telling. How can you believe it? Man's destiny is not calculated, but worked out. A person's fate is in his own hands. How can a person have a good life and a good future if he idles around all day without making progress? Pies can never fall from the sky. Even if the pie falls from the sky, people who get up early and work hard may pick it up and only get one point. Throw away unrealistic fantasies and be down-to-earth is the only way to change your destiny.
