Wu Hanyou is known as the thoroughfare of nine provinces, and the high-speed rail network connects most parts of China. It is an important large-scale transit station and an important inland port of China railway system. The Yangtze River, the third largest river in the world, and its largest tributary, Hanshui River, meet in Wuhan, creating the regional characteristics of Wuhan separated by two rivers and three towns. Rivers crisscross the city, and lakes and harbors are intertwined. The whole water area is 22 17.6 square kilometers, accounting for a quarter of the city's total area, which constitutes the ecological environment of Wuhan's riverside and lakeside waters, so Wuhan has been called Jiangcheng since ancient times.
