王都
The historical records do not clearly indicate whether Doulu Ge continued to serve on staff of Wang's adoptive son Wang Du after Wang Du seized the circuit from Wang Chuzhi in 921. However, he was still described as assistant to the military governor of Yiwu as of 923, suggesting that he did. That year, Li Cunxu the Prince of Jin, to whom Wang Du was a vassal, was preparing to declare himself emperor of a new Later Tang, and was trying to find officials from Tang aristocratic families that he could make chancellors. He initially wanted to make an assistant to himself, Lu Zhi (), chancellor, but Lu declined, recommending Doulu and Lu Cheng instead. Li thus summoned Doulu and Lu Cheng to his provisional imperial government and made them chancellors of the provisional government.
