Pei Yan
In 682, Li Zhe's second wife, Crown Princess Wei, gave birth to a son, Li Chongzhao. Emperor Gaozong was pleased, and he created Li Chongzhao the unprecedented title of "Deputy Crown Prince" (皇太孫, "Huang Taisun"). Later that year, due to a famine in the Guanzhong region (i.e., the region around the capital Chang'an), Emperor Gaozong took up residence at the eastern capital Luoyang, leaving Li Zhe in charge of Chang'an, assisted by the chancellors Liu Rengui, Pei Yan, and Xue Yuanchao. it was said that while Li Zhe was in charge of Chang'an, he often spent his time on games and hunting, and Xue often advised him against spending time in this manner. When Emperor Gaozong heard this, he rewarded Xue and summoned Xue to Luoyang.
