In 923, Later Liang was conquered by its archrival to the north, Later Tang. Later Tang's emperor Li Cunxu, who considered himself the legitimate successor to Tang, took over Later Liang's territory. At that time, he had only commissioned two chancellors, his chief of staff Guo Chongtao and Doulu Ge, neither of whom was familiar with Tang regulations. The popular opinion at that time was that he needed to commission some additional chancellors who were familiar with Tang regulations. Guo recommended Zhao Guangyin, while Doulu recommended Wei. Li Cunxu thus commissioned both Zhao and Wei as chancellors with the designation "Tong Zhongshu Menxia Pingzhangshi" (), and also gave both the title "Zhongshu Shilang" (中書侍郎, the deputy head of the legislative bureau of government (中書省, "Zhongshu Sheng")).
