On February 6, Yichang City, Hubei Province, on the banks of the Yangtze River, saw the beautiful scenery of advection fog. The Yangtze River, green hills and tall buildings were looming in the fog, like a mirage.

Advection fog is the fog formed by the warm and humid air advancing to the colder underlying surface, and the lower part is rapidly cooled.
