Excuse me, in Sichuan dialect, what does the old crow mean by laughing at pig black?

In Sichuan dialect, the old crow laughs at the pig black, which means pot calling the kettle black. The original text of this sentence is: the old crow laughs at the pig black, he doesn't think so! It can be understood as: seeing each other's shortcomings and using them as a handle to belittle each other, but not seeing their own shortcomings.

Crow is a black, ugly and conceited animal. Fairy tales and fables also regard it as a representative who can't see his own shortcomings and pride, conceit and boasting, while pigs are generally regarded as clumsy and ugly animals. The crow here laughs at pig black, which shows that he doesn't know his own shortcomings but sees others' shortcomings without introspection.
