Wu Sansi
In 706, when Emperor Zhongzong's son-in-law Wang Tongjiao () was accused of a treasonous plot with Zhang Zhongzhi (), Zu Yanqing (), and Zhou Jing (), of plotting to kill Empress Wei's lover Wu Sansi the Prince of Dejing (Wu Zetian's nephew) and then depose her, Zhang, while being interrogated, openly accused Empress Wei and Wu Sansi of adultery. Yang and another chancellor aligned with Empress Wei, Wei Juyuan, who were conducting the interrogation, were said to have simply ignored the accusations as if they did not hear them.
