裴矩
After this victory, Dou made peace with Wang Shichong and nominally submitted to Yang Tong, the grandson of Emperor Yang who claimed Sui's imperial title at Luoyang after Emperor Yang's death (and whose court was then controlled by Wang Shichong). Yang Tong, in accordance with Dou's own title, created him the Prince of Xia. Meanwhile, Dou incorporated many key Sui officials into his government, particularly entrusting Pei Ju with reorganizing his government in the form of an imperial one.
