Li Chongjun
In 707, Emperor Zhongzong's crown prince Li Chongjun, who was born of a concubine, angry at insults by Empress Wei's daughter Li Guo'er the Princess Anle and Li Guo'er's husband Wu Zhongxun (武崇訓, Wu Sansi's son) and attempts by Li Guo'er to be made crown princess to displace him, rose in rebellion and killed Wu Sansi and Wu Chongxun, and then approached the palace, intending to seize Empress Wei and Li Guo'er, as well as Emperor Zhongzong's concubine Consort Shangguan Wan'er, who was also Wu Sansi's lover. Yang was one of the high level officials who commanded troops against Li Chongjun, who subsequently was defeated and killed. In the aftermath of the rebellion, the chancellors Zong Chuke and JI Chuna, who wanted to implicate the senior chancellor Wei Yuanzhong (on account that Wei Yuanzhong's son Wei Sheng () had been forced into the rebellion), Yang supported Zong and Ji's efforts, and eventually, Wei Yuanzhong was exiled and died in exile. Later that year, Yang was again made "Zhongshu Ling".
