Fortune-telling mouse cloth shoes _ mouse divination

What does it mean that rats bite other people's things? In fortune telling,

Rats bite someone's things only because someone's things attract rats to bite, which is inferred from causality; From the perspective of fortune telling, you have to show someone's date of birth before you can tell them, otherwise it's nonsense. Judging from the ancient divination records, it is true that some people's lives were specifically bitten by mice, but these strange theories do not conform to modern people's ideas. Modern fortune tellers don't care much about this.
