衛瓘
In 820, Emperor Dezong's great-grandson Emperor Muzong became emperor after the death of his father Emperor Xianzong. That year, shortly after Emperor Muzong ended his mourning period for his father, he wanted to hold a grand feast in honor of the great generals Li Guangyan and Li Su. Li Jue, believing this to be inappropriate so soon after Emperor Xianzong's death, submitted a petition jointly with his colleagues Yuwen Ding (), Wen Yu (), Wei Guan (), and Feng Yao (), urging against it. It was said that while Emperor Muzong did not accept their advice, he treated them with kindness.
