From The Washington Post:
Every day, according to aid workers, a handful of North Koreans make the same decision, driven by hunger, want and oppression. The lucky ones find their way to South Korea, a few by sneaking into embassies in Beijing, some by traveling to neighboring countries to get help. Others get picked up by Chinese police and sent back. But many — aid workers estimate the total is more than 200,000 — end up working underground in China, trapped by their illegal status in menial labor, prostitution, concubinage or petty crime.
