Bridge shrouded in advection fog in SW China's Chongqing

The main districts area of southwest China's Chongqing was covered with a white gauze, hidden in a thick fog on Wednesday morning.

In the sunlight, the Jialing River was foggy. A train ran on the Caijia Rail Transit Bridge covered by fog, just like crossing a fairyland.

Known as "Fog City", Chongqing is covered with a thick layer of fog for an average of 68 days a year, usually in spring and autumn. The fog gives the place an air of mystery.
