Cāngwú

Cangwu was the county surrounding Wuzhou, where the Gui and Xun rivers meet to form the West River. The city served as the seat of both county and prefecture, commanding a waterway between the interior of Guangxi and Guangdong. In the fifteenth century the Ming made Wuzhou a headquarters for military operations across the two provinces. A governor-general was stationed there in 1465, and a permanent governor-general's office was established in 1470. For nearly a century its officials directed forces from the city before the headquarters moved to Zhaoqing in 1566.
