A futuristic eco-city view of Chongqing in 2045. The city skyline is filled with lush vertical greenery—buildings and elevated maglev tracks are covered with living plants. The air is clear and fresh, with bright sunlight and blue skies. Citizens walk or bike along green corridors, while drones monitor air quality. The Yangtze River flows cleanly through the city, with diverse fish visible in the crystal-clear water. Large digital billboards display “Carbon Neutral Zone” and show citizens earning carbon credits. Eco-towers with rooftop gardens, solar panels, and wind turbines blend technology and nature. Scene emphasizes harmony between urban life and ecological sustainability. Realistic style, 16:9 format.
