The questioning room has light off-white upper walls and dark blue lower walls, with a white long table and two office chairs inside. The table is equipped with a landline telephone and two gooseneck microphones. Two sets of khaki multi-layer filing cabinets are placed at the corner, with folders and electronic devices on the top. Two one-way observation windows are installed on the walls, a recessed square ceiling lamp is mounted on the ceiling, and the floor is covered with gray carpet.
