Shídài

Shidai lies in the mountains of southern Anhui, in the upper basin of the Qiupu River. Its name comes from three great stones in a stream that blocked the meeting waters like a weir and prevented boats from passing. The county was re-established under the Tang in 766 from parts of Qiupu, Qingyang and Jing. Its gazetteer describes the waterways and rapids of this rugged district, including the Seven Li River, which leads toward the main course of the Qiupu.
