Wu Sansi
In 705, a coup led by the officials Zhang Jianzhi, Cui Xuanwei, Jing Hui, Huan Yanfan, and Yuan Shuji killed Wu Zetian's lovers Zhang Yizhi and Zhang Changzong, overthrew Wu Zetian, and restored Li Xian to the throne (as Emperor Zhongzong). Princess Taiping participated in the coup as well, and after Emperor Zhongzong assumed the throne, he credited both Wu Youji and his cousin Wu Sansi with participating in the coup as well, and he restored Wu Youji to the greater title of Prince of Ding and gave him the honorific title of "Situ" (one of the Three Excellencies). Wu Youji declined both, and subsequently, when Emperor Zhongzong reduced the Wu clan princes' titles in accordance with public sentiment, Wu Youji's title was reduced to Prince of Leshou. Emperor Zhongzong, believing that 16 officials, including Wu Youji, Wu Sansi, and the officials who actually carried out the coup, were contributors to his reign, granted them iron certificates that were supposed to guarantee that, except for treason, they would be pardoned from death 10 times. (However, Emperor Zhongzong subsequently turned away from these promises as to Zhang, Cui, Jing, Huan, and Yuan, as the five were falsely accused of crimes by Wu Sansi and exiled, and then died or were executed in exile.)
