Chongqing, formerly known as Chungking, is a major city in southwestern mainland China and one of the five national central cities. Administratively, it is one of the People's Republic of China's four direct-controlled municipalities (the other three are Beijing, Shanghai and Tianjin), and the only such municipality in western China. The municipality was created on 14 March 1997, succeeding the sub-provincial city administration that was part of Sichuan Province. In 2007, the municipality of Chongqing had a population of 31.4 million. It has jurisdiction over 19 districts, 17 counties, and four autonomous counties. With an area of 82,300 km² (31,800 mi²), it is the largest direct-controlled municipality, larger even than one province and an autonomous region, as well as Taiwan. It is possibly the world's largest municipality by population and one of the largest by area.

Wuhan is the capital of Hubei province, People's Republic of China, and is the most populous city in central China. It lies at the east of Jianghan Plain, and the intersection of the middle reaches of the Yangtze and Han River. Arising out of the conglomeration of three boroughs, Wuchang, Hankou, and Hanyang, Wuhan is known as "the nine provinces' leading thoroughfare"; it is a major transportation hub, with dozens of railways, roads and expressways passing through the city. The city of Wuhan, first termed as such in 1927, has a population of approximately 9,100,000 people (2006), with about 6,100,000 residents in its urban area. In the 1920s, Wuhan was the capital of a leftist Kuomintang (KMT) government led by Wang Jingwei in opposition to Chiang Kai-shek, now Wuhan is recognized as the political, economic, financial, cultural, educational and transportation center of central China. 

China (officially the People's Republic of China (PRC) – an ancient, mysterious and beautiful land, is always appealing to adventurous foreign visitors. The first thing that strikes visitors to the country is the extraordinary density of its population. In much of China, villages, towns and cities seem to sprawl endlessly into one another along the grey arteries of busy expressways. The main tourist highlights – the Great Wall, the Forbidden City, the Terracotta Army and the Yangzi gorges, are relatively few considering the vast size of the country, and much of China’s historic architecture has been deliberately destroyed in the rush to modernize.
