Definition: Metaphor is blind and lacks investigation.

Allusion: There is a folk story about two blind men who bought a fish together, took it home and cooked it in a pot for a delicious meal. After they made it carefully and carefully, they caught the fish in the pot, but they didn't catch it no matter how they caught it. So the two quarreled. One said that the other stole the fish, and the other was not to be outdone, saying that he did not steal it, someone must be playing tricks. The more the two quarreled, the more fierce they became. When the neighbors heard the news, it turned out that the fish had jumped on the pot table long ago, and the fish had not been cooked at all. This idiom is a metaphor for doing things blindly and lacking in investigation and research.
