Sea of clouds at winter morning

Due to a sharp difference between daytime and nighttime temperatures, water vapor condenses over Wuzhou City, south China's Guangxi Zhuang Autonomous Region on the morning of December 30, 2025. Layers of clouds and mist swirl around mountains and buildings, with residential houses appearing and disappearing in the sea of clouds, resembling a traditional Chinese ink painting.
