Chinese society is a society without an exit mechanism

Either you win consistently, or if you lose even once, you have to pay it all back. You can't afford to lose—if you do, you lose everything. There's no way to carve out what you're allowed to keep versus what you can't. That's what we call having no exit mechanism.

You might make 10,000 yuan illegally, but what you'll eventually have to spit out could be 500,000 yuan, plus three years sewing machines, and your family members will be discriminated against as well. Meanwhile, if Zhang San takes your illegal evidence and turns it in, he could get a 20,000 yuan bonus and a promotion. And notice this: the 20,000 yuan Zhang San receives is completely clean. Think carefully about the principle here—2 is actually bigger than 1.
