张柬之
Huan Yanfan, along with Zhang Jianzhi, Cui Xuanwei, Jing Hui, and Yuan Shuji, were recognized as leaders in Emperor Zhongzong's restoration, and they were put into key positions and created dukes, with Huan becoming "Nayan" (納言)—the head of the examination bureau of government (鸞臺, "Luantai"), and carrying the title of Duke of Qiao. He and the other coup leaders instituted a regime of restoring Tang institutions and deprecating Zhou ones, and when fellow chancellor Yao Yuanzhi displayed distress at Wu Zetian's removal to Shangyang Palace, Zhang and Huan had him demoted out of the capital. (One of the coup participants, Xue Jichang (薛季昶), had advocated to Zhang Jianzhi and Jing the killing of Wu Zetian's nephew Wu Sansi the Prince of Liang in the aftermaths of the killing of Zhang Yizhi and Zhang Changzong, but neither Zhang Jianzhi nor Jing paid Xue's suggestion much heed until it was too late; in fact, Jing argued hard against the killing of the Wus, even though another subordinate, Liu Youqiu, also advocated for the Wus' death and unsuccessfully tried to convince Jing and Huan.) Subsequently, alarmed about the rise of the power of Empress Wei, who carried on an affair with Wu Sansi, as well as that of the monk Huifan (慧範), Huan submitted petitions requesting that Empress Wei's power be curbed and that Huifan be executed. Emperor Zhongzong paid him no heed. When Emperor Zhongzong gave high offices to the sorcerers Zheng Pusi (鄭普思) and Ye Jingneng (葉靜能), Huan again opposed to no avail.
