白马寺
After this incident, however, Huaiyi grew increasingly arrogant and unreasonable, and Wu Zetian began to despise him. To guard herself, she selected a group of strong ladies in waiting. She then had Wu Youning the Prince of Jianchang (the grandson of her uncle Wu Shirang ()) lead a group of strong soldiers to set an ambush at Yaoguang Hall (), and when Huaiyi went to Yaoguang Hall, Wu Youning and his soldiers overpowered him and battered him to death. Huaiyi's body was taken to White Horse Temple and cremated, and then mixed into mud that was set to be used to construct a pagoda.
