The crow laughs at the pig's black next sentence

According to Baidu's Chinese-related materials, the next sentence of the two-part allegorical saying "crow laughs at pig black" means that you don't know yourself, meaning that you don't know yourself, you can't see your own shortcomings or deficiencies, but you laugh at others.

There are a lot of common two-part allegorical sayings-I don't know, thirty-six plans-walking is the best policy, and catching up with the night at five o'clock-getting brighter and brighter.
