南齐
However, in 501, while Xiao Yan was engaged in a civil war against the cruel and arbitrary Southern Qi emperor Xiao Baojuan, Xiao Yan's concubine Ding Lingguang (丁令光) gave birth to a son, Xiao Tong. Despite that, after Xiao Yan overthrew Xiao Baojuan and in 502 forced Xiao Baojuan's brother Emperor He of Southern Qi to yield the throne to him, ending Southern Qi and starting Liang Dynasty (as its Emperor Wu), Xiao Zhengde hoped to be crown prince. Instead, Emperor Wu reversed the adoption and returned Xiao Zhengde to Xiao Hong's line, creating him only the Marquess of Xifeng.
