Despite Wang Sengbian's intent to make Xiao Zhuang's uncle Xiao Fangzhi emperor, he soon changed his mind when he became fearful of Northern Qi after Northern Qi forces scored several victories against his. He accepted the proposal of Emperor Wenxuan of Northern Qi to make Emperor Yuan's cousin Xiao Yuanming emperor, and he declared Xiao Yuanming emperor in summer 555. Wang Sengbian's lieutenant Chen Baxian was displeased by Wang Sengbian's decision, and in fall 555, he made a surprise attack on Jiankang, killing Wang Sengbian and deposing Xiao Yuanming. He declared Xiao Fangzhi emperor (as Emperor Jing). Northern Qi forces almost immediately attacked, and while Chen was able to repel them, in order to try to make peace with Northern Qi, he sent Xiao Zhuang, as well as his nephew Chen Tanlang (), and Wang Min () the son of the key official Wang Chong () as hostages to Northern Qi.
