A South Korean man chose to stay in northeast China's Changchun after his four-year work term with an airline of South Korea expired.

He's now running two coffee shops in Changchun, hoping to promote coffee culture to local residents.

Woo Kyong-jei, who has lived in Changchun for several years, said the recently opened 13th China-Northeast Asia Expo has given him confidence in business cooperation between China and South Korea.
