Korean internet buzzes, and a Mr. A from Korea said,

Before serving his prison sentence, he heavily invested in stocks, and after being released, he found that the stock value had reached about 490 million RMB.
In six years, it multiplied over 400 times, earning more than 470 million RMB in profit.
Mr. A claimed that he had a premonition of losing the lawsuit, and at that time, the Korean stock market plummeted due to the pandemic, so he bought the only cash he had, about 1.2 million RMB, into Xiaoxing Heavy Industries.
As he was in prison, Xiaoxing Heavy Industries' stock price rose from 39 RMB to 16k RMB, making Mr. A a billionaire after his release.
He also confided his feelings,
If he hadn’t gone to jail, he probably would have sold when the stock price hit over 45 RMB (about 1,000 Korean won), but now it’s like going to jail turned him into a master trader—too absurd.
The amount is so outrageous that he doesn’t even know what to do first.
