In spring 560, with Xiao Zhuang—a rival claimant to the Liang Dynasty throne to Western Liang's Emperor Xuan of Western Liang, who was a Northern Zhou vassal and whom Northern Zhou supported—attacking Chen Dynasty territory with his paramount general Wang Lin, Northern Zhou sent its general Shi Ning () to attack Xiao Zhuang's capital Jiangxia (江夏, in modern Wuhan, Hubei). Soon, however, after Xiao Zhuang and Wang were defeated by the Chen general Hou Tian () and forced to flee to Northern Qi and Chen forces subsequently approaching Jiangxia, Northern Zhou abandoned the campaign on Jiangxia, but were able to seize part of Xiao Zhuang's former territory—modern Hunan, which Northern Zhou turned over to Western Liang but sent forces to help defend. In spring 560, Chen made peace overtures to Northern Zhou, which Northern Zhou accepted.
