From The Girl with Seven Names: A North Korean Defector’s Story, by Hyeonseo Lee (William Collins, 2015), Kindle Loc. 2520-2531:
About a week after receiving my [illegally purchased] ID, I found a job that paid almost four times what I earned as a waitress. I became an interpreter and secretary at a South Korean tech company that made compact discs and LED lights. Its office was in Koreatown. My boss was one of the South Korean directors, and part of my role was to accompany him on visits to clients and manufacturing plants. I noticed that the Chinese looked up to South Koreans and addressed them respectfully. I had usually known them to scowl down their noses at North Koreans.
Everything had happened so fast. Overnight I had gone from waiting tables to sitting in boardrooms, interpreting in negotiations, learning how a modern company operated, and the culture in which business was conducted. I was meeting clients and buyers from Taiwan and Malaysia, and mingling socially with South Korean co-workers. The friends I’d made while waitressing knew me as In-hee. In my new job I used the name on my ID card and documentation, Sun-ja. I would have to take care that these two worlds never collided.
The company’s products were manufactured in a plant that was modern even by Shanghai standards. The process was kept entirely dust-free. To enter we passed through a special machine that blew contaminates from our clothing. The South Koreans treated me well. I could not bear to imagine their reaction if they’d known I’d grown up in the bosom of their archenemy. At times this felt surreal. We were all Koreans, sharing the same language and culture, yet we were technically at war.
