Yíshān

Yishan stands on the Long River amid the hills of northwestern Guangxi. As the seat of Qingyuan prefecture, it was a political and military centre for a region whose communities included many non-Han peoples. The prefecture had been created under the Southern Song and restored by the Ming after a period of Yuan reorganisation. In the early fifteenth century, resistance in Yishan and neighbouring districts brought repeated campaigns by Ming forces.
