陈后主
In spring 589, when Xiao was at Jiankang, the Sui general Heruo Bi () took the chance to cross the Yangtze (as part of the overall campaign by Emperor Wen of Sui to destroy Chen) and captured Jingkou (, the capital of Southern Xu Province). Soon, Heruo arrived at Zhongshan (now Purple Mountain), near Jiankang, and Xiao volunteered to engage Heruo. Chen Shubao agreed, despite warnings by another major general, Ren Zhong (), not to engage Heruo. Xiao's own motivation level was said to be low, however, due to an affair that Chen Shubao was having with Xiao's wife. Heruo defeated him and captured him. Heruo threatened him with beheading, and yet Xiao would not prostrate himself. Heruo was impressed and spared Xiao. Subsequently, Heruo captured Chen Shubao as well, and Xiao obtained permission to cook and serve Chen Shubao one final meal from the Chen imperial kitchen as well as to make a tearful farewell—acts that greatly impressed Sui's Emperor Wen.
