 "Krong" was probably a word in the Austroasiatic language of local peoples such as the Yue.Similar to "*krong" in Proto-Vietnamese and "krung" in Mon, all meaning "river," it is related to modern Vietnamese "sông" (river) and Khmer "kôngkea" (water).By the Han dynasty, "Jiang" had come to mean "any" river in Chinese, and this river was distinguished as the "Great River" ().
