A mouse is holding an ingot in the sea and guessing an idiom.

Explanation: treat money as life. Describe extreme meanness.

From: Ms. Qing Lingnan Yu Yi's "Heroine of Eastern Europe" for the fourth time: "I think in the recent world, no matter what heroes are, they all love money like life, not to mention those who have to fight with wolves, officials and rats, and it is even worse if they have no money."

That man is very selfish.
