Here is an article that provides a reminder of how difficult the life for many North Korean defectors has been before finding refuge:
Back in my home country, I was charged with trying to escape North Korea and sent to a jail where a dozen male and female, young and old prisoners were squeezed into a room no bigger than a metre square. There was only one toilet in the corner of the room and no privacy.
Like other inmates, I was treated as an enemy of the state and forced to do hard labour, clearing the hills of trees so that crops could be planted. I became so malnourished that my skin turned black and my body was skeletal. I lost big clumps of hair and felt utter despair. But the greatest pain was in my heart. I couldn’t bear being separated from my child. On days I thought about death, the thought of seeing my son again was all that kept me going.We were not allowed to wear shoes in the prison, in case we tried to run away. Slowly the skin on my feet became broken and calloused from the rough stones on the ground. My wounds became infected until finally gangrene set in. It was desperately painful, but what I didn’t realise was this would be my passport to freedom. The prison doctor told me that the United Nations had intervened to condemn the conditions in North Korea’s prisons, and he persuaded the guards that I needed rest.Thanks to him, I was sent to a prison for children where I was to stay until I was well enough to return to finish my two-year sentence. But after two months, when I was able to walk with a limp, I begged the guards to let me leave. My father had passed away just after I left for China, and I told them I wanted to visit his grave. In a rare moment of generosity, they agreed to let me go and, the minute I was out, I headed for the Chinese border again. I had no money, and I knew the only hope of seeing my son again was to approach another trafficker on the North Korean side and tell him I wanted to be sold again into marriage. Once inside China, I managed to escape. [Yahoo News]
