In this June 22, 2016, photo made with an instant camera, Kang Jong Jin, a 28-year old former soldier who attaches soles onto shoes at a shoe factory in Wonsan, North Korea, poses for a portrait at his work station. Kang, who has been working longer hours during this 200-day "speed campaign" in line with North Korean leader Kim Jong Un's vows to raise the nation's standard of living and energize his five-year plan to develop economy, says that he wants to contribute to Kim's plan by taking courses to improve his scientific and technological skills.
