The Yangtsze-kiang is the chief waterway of China. The river, flowing through the centre of the country, after a course of 2900 m., empties itself into the Yellow Sea in about 31 N. Unlike the Yellow river, the Yangtsze-kiang is dotted along its navigable portions with many rich and populous cities, among which are Nanking, An-ching (Nganking), Kiu-kiang, Hankow and I-ch~ang.
