This is a creative synthetic image themed on Clean Air and Future City. Based on clear bright blue sky and fluffy white clouds, it shows partial industrial chimney at the lower left corner, and fresh green leaves with crystal water droplets at the upper right. Overlaid with translucent spherical light effect and fine star elements, it integrates industrial scene and natural green elements, conveying the low-carbon environmental protection concept that future cities balance industrial development and ecological protection to guard clean air, full of good expectations for green sustainable urban life.
