It was said that while serving as chancellor during Wu Zetian's and Emperor Zhongzong's reigns, Doulu was careful in his own behavior and did not dare to curb the powers of Wu Zetian's lovers Zhang Yizhi and Zhang Changzong, as well as Wu Zetian's nephew Wu Sansi the Prince of Dejing, who became exceedingly powerful in Emperor Zhongzong's reign due to his personal influence on Emperor Zhongzong and his affair with Emperor Zhongzong's powerful wife Empress Wei. Doulu was much criticized by popular opinion at the time.
