У Цзэтянь
Around this time, Li Zhaode secretly suggested to Wu Zetian that Wu Chengsi's powers were becoming too great and would soon rival her own. Wu Zetian agreed, and she gave Wu Chengsi the highly honorific title of "Tejin" (特進), but removed him from being chancellor. Wu Chengsi subsequently tried to accuse Li Zhaode of crimes, but Wu Zetian did not believe him. Wu Chengsi continued to be honored, however, and around the new year 693, when Wu Zetian offered sacrifices to heaven and earth, she personally offered sacrifices first, and then had Wu Chengsi and Wu Sansi follow her in sacrificing.
