River system, southern
China. Known as the Nanpan and then the Hongshui in its upper course, the Xi proper begins as it enters Guangdong province from eastern
Guangxi autonomous region. It flows east through Guangdong and then through the vast Pearl River delta before entering the South
China Sea west of
Hong Kong near
Macau; the city of
Guangzhou (Canton) is in its delta. It is about 1,200 mi (1,930 km) long, shorter than other important Chinese rivers, but its volume of flow is second only to that of the
Yangtze River (Chang Jiang). It is the great commercial waterway of southern China, linking the delta cities with the interior.
