Wu Mingche
In light of Northern Qi's defeat, Chen, then ruled by Chen Xu (who had deposed Emperor Fei and took the throne himself as Emperor Xuan), launched an attack commanded by Wu Mingche on Pengcheng (modern Xuzhou, Jiangsu), an important city on the former Chen/Northern Qi border. Emperor Wu sent Wang Gui to relieve Pengcheng, and in spring 578, Wang defeated Wu, capturing him.
