Hwa-Young* works in China with women who flee North Korea or are abducted by people traffickers and taken across the border.
Many of the women are tempted to leave behind a miserable life when they are told there are jobs waiting for them in China. But often they are sold on to brothels or into marriages with poor Chinese Korean men.
About half of the 250 women who have found refuge through small church groups have been helped by Hwa-Young in the last year.
