This is a northern dialect, which means that a person is extremely stingy. For things that are unprofitable, we must try our best to squeeze them out, even if they are useless, we must possess them. This is a kind of psychology that we will lose even if we don't take advantage.
At the same time, there is also a saying in Sichuan: knock things so hard that things are deformed and deformed, and ordinary things become freaks.
