Folded Paper Geometry in Urumqi Terminal Twilight

Cool blue hour light falls through high windows of the restored Urumqi train terminal, illuminating a cluster of folded paper forms. The paper edges catch the indigo twilight, creating sharp highlights against deep shadows. Condensation blurs the glass nearby, softening the background into a muted gray haze. Winter cold is visible in the frost patterns along the window frames. The geometric shapes stack in rhythmic layers, their crisp white surfaces against the dark architectural steel. Shadows stretch across the paper folds, defining the depth of each crease. A thin line of ice forms at the corner of the glass pane where the cold meets the warm interior air.
