An interior scene in Fengtai District, China, depicts a large, double-leaf metallic door resembling a vault entrance. The door is finished in a matte silver/grey and shows signs of wear, including scratches and dark, reddish-brown streaks, particularly around the central vertical seam and recessed handle. The left door leaf features two chrome-plated, three-spoke circular wheels, positioned vertically. The right door leaf has a recessed vertical handle, below which two red electrical wires are visibly connected to a small white rectangular component. Four horizontal, cylindrical metal bars are attached vertically along the far right edge of the right door leaf. Riveted rectangular plates are affixed to both door leaves and their frame. To the right of the door, a light-colored wall panel displays the numerals "1303" in light grey. The overhead ceiling is white, equipped with a rectangular fluorescent light fixture. The floor is tiled in shades of grey. No individuals or actions are visible.
