Thanh Thao, 43, of Hai Phong, knows this struggle all too well. She has faced it alongside her son, Kim Min Jun, since returning to Vietnam.
Thao married through a matchmaking service in 2006, but was disillusioned upon arriving in South Korea. Her husband, 24 years older, was an unemployed alcoholic who had been divorced four times. They lived in a remote mountain village near the border, where she was forced to live with his son from a previous marriage, who was four years older than her.
In 2010 her husband unilaterally filed for divorce so he could marry a sixth wife.
