Wūjiāng
Wujiang is a crossing on the river south of Bozhou, where a steep road descends to the water between high hills. An old relay route linked the crossing with the country to the north and south, and a fortified pass guarded the approach. During the Ming campaign against Yang Yinglong in 1600, imperial troops fought their way across the river, but the Bozhou forces inflicted a heavy defeat on one army here. After the campaign the Ming restored a relay station at Wujiang, keeping the crossing on the route between Sichuan and Guizhou.
