Why is it said that the wearing trend of the genus Rat is a bodhisattva after calculation by the master?

Bodhisattva is the assistant bodhisattva of Amitabha. The other is Guanyin Bodhisattva. But as for the so-called master's calculation, I don't think it makes sense. Both the Buddha and the Great Bodhisattva are compassionate beings, regardless of you and me, regardless of the genus. Don't be superstitious about the master. That is not the true meaning of Buddhism.
