Pei Yan
In 682, as the Chang'an region was suffering from a famine, Emperor Gaozong, in order to reduce the pressure on the imperial food supply, took up residence at the eastern capital Luoyang. He left Li Zhe in charge of Chang'an, assisted by Liu and fellow chancellors Pei Yan and Xue Yuanchao. In 683, Emperor Gaozong summoned Li Zhe to Luoyang in anticipation that he would soon hold a grand ceremony to sacrifice to Heaven and Earth at Mount Song, leaving Li Zhe's son Li Chongzhao, the deputy crown prince, nominally in charge of Chang'an, again assisted by Liu, Pei, and Xue. After Li Zhe arrived in Luoyang, Emperor Gaozong, who had long been ill, died around the new year 684. Li Zhe became emperor (as Emperor Zhongzong), although the Still government was actually completely controlled by Emperor Gaozong's wife and Emperor Zhongzong's mother, Empress Dowager Wu (later known as Wu Zetian), and even this time all the rights and powers of the empire were in her strong hands alone.
