How do people get out of North Korea?

By crossing the Tumen river, usually through the Chinese border.They pay the border guard and the broker who get them through.Many of them face the danger of having their relatives who stay behind retaliated against, although that seems to have become less of a danger in recent years, as defectors usually send their families money and manage to make the occasional phone call through mobile phone smuggled intoNK from China.

It was very, very carefully.

The majority of people sneak across one of the rivers that are near China.
