and Li Zhen's son Li Chong, Prince of Langye, Xue Yi, Xue Xu, and Xue Shao were discovered as having conspired with Li Chong. Xue Yi and Xue Xu were beheaded, while Xue Shao was caned 100 times and starved to death — which led to more suffering, but which allowed his body to remain whole and thus was considered a more honorable death. In 690, Empress Dowager Wu wanted to remarry Princess Taiping to Wu Youji, a grandson of Empress Dowager Wu's uncle Wu Shileng (武士稜). Wu Youji, however, was already married, and Empress Dowager Wu secretly had Wu Youji's wife assassinated so that Princess Taiping could marry him. With Wu Youji, Princess Taiping would have an additional two sons — Wu Chongmin (武崇敏) and Wu Chongxing (武崇行) — and one daughter. A possible second daughter, titled Lady Yonghe (永和县主), was also born to them. During Wu Zetian's reign: Increasing role in politics Later in 690, Empress Dowager Wu had Emperor Ruizong yield the throne to her, establishing the Zhou dynasty with herself as its "emperor" (therefore interrupting the Tang dynasty). In or before 697, Princess Taiping recommended Zhang Changzong to serve as Wu Zetian's lover. Zhang Changzong further recommended his brother Zhang Yizhi as well. Also in 697, Wei Suizhong (衛遂忠), a friend of the secret police official Lai Junchen, revealed that Lai had intended to accuse Princess Taiping, the Wu clan princes, Li Dan, and Li Zhe of treason. Princess Taiping and the Wu clan princes, in response, accused Lai of crimes, and Wu Zetian put Lai to death. In 699, when the chancellor Zong Chuke (a son of Wu Zetian's cousin) and Zong Chuke's brother Zong Jinqing (宗晉卿) were accused of corruption and exiled, Princess Taiping visited the Zongs' mansions and commented, "Once we look at their mansions, it is like we have not lived." Also in 699, Wu Zetian, in fear that after her death that Li Zhe (who by now had changed his name to Li Xian and then further to Wu Xian and had been recalled to be crown prince again) and the Wu clan princes would not be able to coexist peacefully, had him, Li Dan, Princess Taiping, Wu Youji, and the other Wu clan princes swear an oath to each other and read the oaths to the gods. The oaths were then carved on iron and kept in the imperial archives.
