When did Li Linfu serve as chancellor of the Tang Dynasty?
Li Linfu
Meanwhile, Li Linfu was said to be constantly bribing the eunuchs and ladies in waiting himself to keep an eye on Emperor Xuanzong's emotions and acts, to allow him to carry out actions that would help him stay in power.  For example, when Emperor Xuanzong was impressed by the official Lu Xuan (盧絢) on one occasion and appeared poised to promote him, Li Linfu, viewing Lu as a potential threat, summoned Lu's younger clan members and informed them that Emperor Xuanzong was set to make Lu the commandant of distant Jiao Prefecture (交州, roughly modern Hanoi, Vietnam) or Guang Prefecture (廣州, roughly modern Guangzhou, Guangdong)—technically promotion, but considered at that point to be positions of exile—causing Lu to, in fear, submit a resignation, asking to be made a member of the staff of Li Yu (whose name was changed to Li Heng by that point).  Lu Xuan was ultimately made a member of Li Heng's staff, out of contention for the chancellorship.  Meanwhile, when Emperor Xuanzong appeared poised to recall Yan Tingzhi, perhaps to make him chancellor, Li Linfu tricked Yan's brother Yan Sunzhi (嚴損之) into believing that the best way to have Yan Tingzhi recalled was to claim that Yan Tingzhi was ill.  Li Linfu then managed to have Emperor Xuanzong make Yan Tingzhi a member of Li Heng's staff as well, along with Qi Huan (齊澣), another influential senior official that Li Linfu viewed as a threat.
