王世充
Yang Dong posthumously honored his father Yang Zhao as an emperor, and honored his mother Consort Liu as empress dowager. The government was led by a collective leadership of seven officials—Duan Da (whom Yang Dong created the Duke of Chen), Wang Shichong (Duke of Zheng), Yuan Wendu (Duke of Lu), Huangfu Wuyi (Duke of Qi), Lu Chu, Guo Wenyi (), and Zhao Changwen (). They became known as the "seven nobles."
