5384 Changjiangcun           Discovered 1957 Nov. 11 by C.-H. Chang at the Purple Mountain Observatory.
The village of Changjiangcun, at the harbor of Zhangjiagan city in Jiangsu province, has the same name in Chinese as what is known in English as the Yangtze River. With painstaking effort, the residents promote their village as a "window" on the river delta, calling it "the famous flower of Yangtze River".
