What is the largest city in China?

Chongqing is the fourth municipality directly under the Central Government of China, the largest city in China and the largest city in the world.

It has the largest territory and the largest population (up to 30 million). However, the word "big" in Chongqing is a bit inappropriate, because Chongqing is a bit equivalent to the organizational system of a province. Many people think that Chongqing should be juxtaposed with Hubei and Guangdong, not Wuhan and Guangzhou.

Economically speaking, Shanghai is the largest city, and politically speaking, Beijing is the largest.
