Chongqing, with over 100 days of fog per year, is known as the "Fog City" (); this is because in the spring and fall, a thick layer of fog enshrouds it for 68 days per year. During the Second Sino-Japanese War (1937–1945), this special weather possibly played a role in protecting the city from being overrun by the Imperial Japanese Army.
