Yang would be chancellor and entrusting his household to Yang. Upon Li Linfu's death, however, Yang induced Li Linfu's son-in-law Yang Qixuan () into corroborating that Li Linfu was involved with Li Xianzhong. As a result, Li Linfu was posthumously stripped of honors and his family members were exiled. As chancellor Meanwhile, Emperor Xuanzong made Yang Guozhong You Xiang () -- the head of the legislative bureau of government (中書省, Zhongshu Sheng) and a post considered one for a chancellor; he also made Yang the minister of civil service affairs (文部尚書, Wenbu Shangshu), and further allowed him to keep his command of Jiannan.

At this time, Yang and his relatives were living in extreme luxury, and he and the Lady of Guo had connected mansions and were openly displaying their closeness. Meanwhile, whenever Consort
