Emperor Xizong of Tang
In 677 (during the reign of Emperor Gaozong), Chen Zheng, together with his son Chen Yuanguang, led a military expedition to suppress a rebellion of the She people. In 885, (during the reign of Emperor Xizong of Tang), the two brothers Wang Chao and Wang Shenzhi, led a military expedition force to suppress the Huang Chao rebellion. These two waves of migration from the north brought the language of northern Middle Chinese into the Fujian region. This then gradually evolved into the Zhangzhou dialect.
