Xiákǒu
Xiakou was a fortified place in the mountain country north of Wugang. Ten stockades were set up in the Song to guard the district, and Xiakou was one of them. During the Ming, officials maintained a patrol post here to control approaches through the hills, including routes used by Yao communities. The post administered numerous settlements and mountain places, their names survive in a list of the villages subject to Xiakou.
