The extent of Empress Dowager Chinu's influence on political matters is unclear, but she became a passive participant in Emperor Wu's plot to remove his cousin Yuwen Hu, who controlled the political scene and who had killed both of his predecessors—his brothers – Emperor Xiaomin and Emperor Ming. In 572, after a conference with Yuwen Hu, Emperor Wu invited Yuwen Hu inside the palace to meet with Empress Dowager Chinu – something that Yuwen Hu did on a regular basis. On the way, he told Yuwen Hu that Empress Dowager Chinu was having problem with alcoholism and not listening to his advice to stop her drinking, so he wanted Yuwen Hu to advise her to change her ways as well. He further gave Yuwen Hu the text of the "Jiu Gao" (酒誥) – an anti-alcoholism declaration written by King Cheng of Zhou – and suggested that he read the "Jiu Gao" to Empress Dowager Chinu. Once they reached her palace, Yuwen Hu, pursuant to Emperor Wu's request, started reading the "Jiu Gao". Before he could finish it, Emperor Wu stepped behind him and used a jade tablet to strike the back of his head. Yuwen Hu fell to the ground, and Yuwen Zhi, who was hiding nearby, jumped out, and cut off Yuwen Hu's head, ending Yuwen Hu's hold on power.
