As one of China's National Central Cities, Chongqing serves as a center for finance in the Sichuan Basin and the upstream Yangtze, as well as for manufacturing and transportation. It is a connection in the Yangtze River Economic Belt and a base for the country's Belt and Road Initiative.

The Chinese municipality of Chongqing, which is the largest city proper in the world by population, comprises a huge administrative area of 82,403 km², around the size of Austria. However, more than 70% of its 30-million population are actually agricultural workers living in a rural setting.

Chongqing is the largest city in the world by population when measured in terms of municipality, although it is in third place if it is measured in terms of metropolitan area, just behind Tokyo (39 million people) and Jakarta (34.5).

Chongqing is an amazing city, very vertical like Hong Kong, very hilly like San Francisco, very hot and humid like Florida, and very Spicy like Mexico. The people are great, very friendly and kind. The traffic is a little scary, as people ignore all rules of the road, but it keeps moving.
