By 572, Yuwen Hu had controlled the military for 16 years and the government for nearly as long. Emperor Wu had long wanted him out of the way, although he showed few outward signs of it. He conspired with Yuwen Zhi, distant relatives Yuwen Shenju () and Yuwen Xiaobo (), and Wang Gui () against Yuwen Hu. In spring 572, he made his move. After Emperor Wu and Yuwen Hu had a meeting, he invited Yuwen Hu into the palace to meet with Empress Dowager Chinu. On the way to her palace, 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" () -- 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. Yuwen Hu's sons, brothers, and key associates were all executed.
