Taiyuan Construction Shell Before Dawn

Soft overcast light falls through the unfinished corridor near Taiyuan, illuminating bare concrete walls and a floor scattered with fine dust. Metal valve stubs protrude from the base, their cold surfaces catching the faint glow of a work lamp settled in a distant corner. Bundled duct sections sit crated against the wall, wrapped in protective plastic that crinkles under the dim illumination. Hanger rods dangle vertically from the rough ceiling, creating a grid of shadows that stretch across the gray floor. The scene holds a quiet urgency, with tools and materials arranged for the morning shift. One rust stain marks the edge of a steel plate lying flat on the ground.
