I was born in Pyongyang, North Korea. My father was a party official and our family was orginally well-off in North Korea. At about the age of 17 (in the year 2006) my father was in trouble and being sent to labour camp. I and mother and my younger sister flee to China by passing the North Korea-China border. We were then "bought" by 3 Chinese men and became their wives. I married to a Chinese man in the rural area of Shandong. He was 20 years older than me. I got a temporary right of residence after about a year.
I give birth to a son in the second year of marriage. My husband died last year. I then left our son to his family and went to the city nearby. Shortly after I leaved China to Macau and now working in a night club in Macau.
I shall send the proof to moderator
EDIT : For the proof, I think that the moderator may have some difficulty to verify it. I have provided to the moderator my China identity card (of course in Chinese) which shows that I am ethnics Korea (朝鮮). However, the identity card cannot verify I am from the North and I have not any other documents in possession to prove that. I can only say that it is not common and usual for a South Korean to emigrate to China. May be the moderator can at least verify what I said here and you can choose to believe the rest or not.
