1. Mountain city
Chongqing is a city built on mountains. Mountains account for 76% of the total area, hills account for nearly 16%, and plains account for less than 4%.
Chongqing, known as "Ba" in ancient times, is the birthplace of Ba Yu culture, with a history of 3000 years. Because the Jialing River located in Chongqing was called Yushui in ancient times, "Yu" is still used as the abbreviation of Chongqing.
Chongqing has the largest number of bridges and the largest scale in China, which is inseparable from the mountain city. It is also known as the only "bridge capital" in China.
Because of the Jialing River and the Yangtze River, Chongqing is also known as "the first river city in China".
Yu was the appellation that appeared in the Sui Dynasty, because the Jialing River was called "Yushui" at that time, and Chongqing was located on the Bank of the Jialing River, so it was called "Yuzhou".
6. Fog city
In winter and spring, Chongqing has light clouds and heavy fog, so it is named. This fog is fog, not haze.
