Meanwhile, the prime minister Yang Yin—a son-in-law of Grand Empress Dowager Lou, as he had married the former wife of Eastern Wei's Emperor Xiaojing after Emperor Wenxuan killed him around the new year 552—became suspicious that Gao Yan or another son of Grand Empress Dowager Lou, Gao Zhan the Prince of Changguang would try to seize the throne. Yang's associates Kezhuhun Tianhe (可朱渾天和) and Yan Zixian (燕子獻) were even considering killing the two princes and putting Grand Empress Dowager Lou under house arrest and transferring her authority to Emperor Fei's mother Empress Dowager Li. However, what they considered were leaked to Grand Empress Dowager Lou by Empress Dowager Li's lady in waiting Li Changyi (李昌儀), and the two princes took preemptive action, ambushing Yang and his associates and forcing them into the palace. Yang and his associates were executed, and power fell into the hands of Gao Yan. (Despite Grand Empress Dowager Lou's opposition of Yang's plans, however, she realized that he was acting out of his loyalty to Emperor Fei, and she personally mourned him, and because before his death, one of Yang's eyes had been battered out of its socket, she made an eye of gold and pressed it into Yang's eyesocket.)
