After Xiao Daocheng took over the throne in 479, ending Liu Song and establishing Southern Qi (as its Emperor Gao), Xiao Zhangmao, as his oldest grandson, was created the Prince of Nan Commandery, and Wang Baoming became the Princess of Nan Commandery.
Later that year, he deposed (again in the name of Empress Dowager Wang) and killed Xiao Zhaowen as well, taking over the throne personally (as Emperor Ming).
Empress Dowager Wang, while still carrying her title, vacated the palace and took up residence at the old mansion of Emperor Wu's brother Xiao Qiang (蕭鏘) the Prince of Poyang, whom Xiao Luan had killed as well, and the residence became known as Xuande Palace as well.
Empress Dowager Wang's activities during the reigns of Emperor Ming and his son Xiao Baojuan are not completely clear.
