During the Sung (Song) period (Northern Sung, 960-1127, Southern Sung, 1127-1279) we again hear in the Chinese annals of Muslim mercenaries.

This in Chinese Hui Hui Jiao was unversally accepted and adopted for Islam by the Chinese, Khiran, Mongols, and Turks of the Chinese border lands before the end of the eleventh century.
