Chongqing is a port city with the largest municipal area and population in China. It is situated in the upper reaches of the Yangtze River at the confluence of the Yangtze and Jialing Rivers in southwest China. With an area of 82,400 square kilometers (31, 800 square miles), Chongqing shares borders with the provinces of Hubei, Hunan, Guizhou, Sichuan, and Shaanxi. Besides the Han who form the majority of its total population of 30.9 million, numerous ethnic groups reside in Chongqing, including Yi, Tibetan, Miao, Qiang, You and Tujia.

Since its founding 3,000 years ago, Chongqing has been called Jiangzhou, Yuzhou, and Gongzhou, before getting its present name nearly 800 years ago. Since the Qin Dynasty (221 BC-206 BC), many dynasties have set up administrative institutions that have endowed the city with brilliant cultures. Perched beside the Yangtze, the "Golden River," Chongqing symbolizes Yangtze River civilizations and is the cradle of Bayu culture.
