Wuhan (simplified Chinese: 武汉; traditional Chinese: 武漢; pinyin: Wǔhàn [wùxân] ) 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 the Jianghan Plain, and the intersection of the middle reaches of the Yangtze and Han rivers. Arising out of the conglomeration of three districts, 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. Because of its key role in domestic transportation, Wuhan was sometimes referred to as the "Chicago of China."
