and Princess Taiping tried to spread the sentiment that Li Longji should not be crown prince, and that his older brother Li Chengqi the Prince of Song, who was born of Empress Liu, or his cousin Li Shouli the Prince of Yong (the son of Emperor Ruizong's older brother Li Xian (note different character than Emperor Zhongzong)) should be crown prince. In 711, Song and Yao, trying to end to political uncertainty, suggested sending Li Chengqi and Li Shouli out of the capital Chang'an to serve as prefectural prefects, while sending Princess Taiping and her husband Wu Youji (Wu Zetian's nephew) to settle in the eastern capital Luoyang. Emperor Ruizong accepted the suggestion except as to Princess Taiping's place of settlement (sending her to the closer Pu Prefecture (蒲州, roughly modern Yuncheng, Shanxi) rather than Luoyang). When Princess Taiping found out, however, she complained bitterly to Li Longji, and Li Longji, in fear, publicly requested that the orders be rescinded and that Song and Yao be put to death for alienating him from his aunt, brother, and cousin. In response, Emperor Ruizong cancelled the orders and demoted both Song and Yao to be prefectural prefects—in Yao's case, to be the prefect of Shen Prefecture (申州, roughly modern Xinyang, Henan). He was then moved several times in his office, to be the prefect of Xu Prefecture (徐州, roughly modern Xuzhou, Jiangsu—a different Xu Prefecture than where he had served before) and then Lu Prefecture (潞州, roughly modern Changzhi, Shanxi). He was then made the secretary general at Yang Prefecture (揚州, roughly modern Yangzhou, Jiangsu), and was said to have governed it so well that the people built a monument dedicated to him. Eventually, he became the prefect of Tong Prefecture (同州, roughly modern Weinan, Shaanxi). During Emperor Xuanzong's reign In 712, Emperor Ruizong passed the throne to Li Longji (as Emperor Xuanzong), but, at Princess Taiping's suggestion, retained most imperial powers as Taishang Huang (retired emperor). In 713, after Emperor Xuanzong, claiming that Princess Taiping was planning to kill him, carried out a reprisal (先天之变, Xiantian incident) against her, forcing her to commit suicide and executing many of her associates, Emperor Ruizong transferred his authorities to Emperor Xuanzong. In winter 713, Emperor Xuanzong carried out a major review of troops at Xinfeng (新豐, in modern Xi'an, Shaanxi), during which, due to the ceremony not being properly organized as it was supposed
