太平公主
In 711, Song and another chancellor, Yao Yuanzhi, tried to persuade Emperor Ruizong to carry out a plan that they believed would end her plotting. They proposed that the two princes who arguably had superior claims on the throne than Li Longji — Li Chengqi and Li Shouli (whose father Li Xian (note different character than Emperor Zhongzong) was an older brother to both Emperors Zhongzong and Ruizong) — be sent out of the capital Chang'an to serve as prefectural prefects, while Princess Taiping and Wu Youji be sent to live in Luoyang. They also proposed that Li Longji be put in charge of most affairs of state. Emperor Ruizong initially agreed and made the orders as Song and Yao suggested, except that he believed that Luoyang was too far and therefore sent Princess Taiping and Wu Youji only to Pu Prefecture (蒲州, roughly modern Yuncheng, Shanxi). After Princess Taiping found out that the plan was conceived by Song and Yao, however, she was incensed and let Li Longji know her anger. In fear, Li Longji submitted a petition accusing Song and Yao of alienating him from his brothers Li Chengqi and Li Shouli (who was actually a cousin but was raised with Emperor Ruizong's sons) and aunt Princess Taiping, asking that the two be put to death. Emperor Ruizong, in response, demoted Song and Yao and recalled Princess Taiping, Li Chengqi, and Li Shouli to the capital. After Song and Yao were removed, Princess Taiping further suggested that a major reform in the civil service system that they carried out — removing officials improperly commissioned during Emperor Zhongzong's reign — be reversed, and Emperor Ruizong agreed. Later that year, in order to please Wu Youji, Princess Taiping requested that the tombs of Wu Zetian's parents Wu Shihuo (武士彠) and Lady Yang be restored to imperial tomb status (they had been reduced to the status of tombs of nobles after Emperor Zhongzong's death), and Emperor Ruizong agreed. Also that year, when the officials Xue Qianguang (薛謙光) and Murong Xun (慕容珣) accused an associate of Princess Taiping's, the Buddhist monk Huifan (慧範), Princess Taiping pleaded on Huifan's behalf, and Emperor Ruizong, believing that Xue and Murong had only accused Huifan because they could do so during the time that Princess Taiping was out of the capital, demoted Xue and Murong.
