Li Chongjun
In 707, Emperor Zhongzong's son by a concubine, Li Chongjun the Crown Prince, angry that Empress Wei's daughter Li Guo'er the Princess Anle and her husband Wu Chongxun (武崇訓, Wu Sansi's son) repeatedly humiliated him and were trying to have Li Guo'er made crown princess to displace him, rose in rebellion and killed Wu Sansi and Wu Chongxun, but subsequently was defeated and killed in exile. Zheng became an associate of Empress Wei's, and in 708, when he was serving as the minister of worship (太常卿, "Taichang Qing"), submitted an interpretation of popular songs that suggested that both Emperor Zhongzong and Empress Wei's authorities had divine origins, which pleased Emperor Zhongzong greatly.
