What does fortune telling waterproof mean?

It means that a person's fate is very strong, just like waterproof, and will not be affected by external factors. It may also remind people not to believe in fortune telling or divination, because the real fate is in their own hands and should not be influenced by external factors. It should be noted that fortune-telling and divination have no scientific basis and should not be used as the basis for decision-making or action. We should change our destiny with practical actions and efforts.
