A massive Powerball win draws attention to a little-known immigrant culture in the US

An immigrant from Laos who has been battling cancer won an enormous $1.3 billion Powerball jackpot in Oregon earlier this month. But Cheng “Charlie” Saephan's luck hasn't just changed his life — it's also drawn attention to Iu Mien, a southeast Asian ethnic group with origins in China, many of whose members fled from Laos to Thailand and then settled in the U.S. following the Vietnam War. During a news conference Monday introducing him as one of the jackpot winners, Saephan wore a sash identifying himself as Iu Mien. Cayle Tern, president of the Iu Mien Association of Oregon, says the win is significant because so many Iu Mien refugees came to the U.S. with nothing.
