At night, a small white POLICE truck with flashing blue and red lights is parked on the side of a street. Behind the truck and to the right, a person in a green uniform sits on the ground, looking at a device. A tall, dark palm tree is in the foreground to the right, with a vertical sign attached to it. The sign advertises “DANANG Smart City.” Buildings of varying heights are visible in the background, illuminated by streetlights. The street and sidewalk appear to be clean and well-maintained.
