I went to Chungryangri Market in Seoul yesterday. Before crossing the road I saw this warm scene on a very cold day of -13 C. It was a spot for recycling materials for copper and other metalic goods. A big truck was there and left just before I began to draw. They seemed to take some rest warming themselves after loading the truck with collected things. The scene was very impressive with white smoke, red flame, and the workers in silhouette.
