China's population buys hundreds of billions of lottery tickets every year. The advantage Ren gained by buying thousands was practically nonexistent. But it fucking worked! It's unclear exactly how much money Ren won, but it was enough that he happily returned the original 200,000 yuan to the vault and no one suspected a thing. Against all odds, he got away with it. He won the lottery of crime, and also won the actual lottery.
So of course he decided to do it again, except with way more money this time.
"I just can't stand the sight of an unbalanced pile of cash."
Ren and another vault manager, Ma Xiangjing, "borrowed" 32 million yuan ($4.3 million) from the bank and spent a whopping 31 million of it on lottery tickets. And that's when the laws of probability decided to start working normally again. That is, they didn't win shit. Panicking, they helped themselves to another 18 million yuan, but again, the only thing they accomplished was making some ticket vendors very happy. In total, they stole/spent the equivalent of $6.7 million and made back only $12,700. They pulled off one of the country's biggest bank thefts ever for the amount of money you might get from stealing a single used car.
Eventually, bank officials couldn't help but notice that the place was a lot draftier than usual, and the thieves were found out. Sadly, this story has a not-so-hilarious epilogue. Because this was China, instead of getting sent to a mandatory decade-long spa and being played by Leo DiCaprio in a film, the two white-collar criminals were executed.
