Li Linfu
Li Linfu () (died January 3, 753), nickname Genu (), formally the Duke of Jin (), was an official of the Chinese Tang Dynasty, serving as a chancellor for 18 years (734–752), during the reign of Emperor Xuanzong—one of the longest terms of service for a chancellor in Tang history, and the longest during Xuanzong's reign.
Li Jingxuan
Li Jingxuan (李敬玄) (615–682), formally Duke Wenxian of Zhao (趙文憲公), was an official of Tang China, serving as Chancellor of the Tang dynasty during the reign of Emperor Gaozong. He was famed for his knack of organizing the civil service system efficiently, but his downfall began in 678, when he, over his objection, was put in command of an army against the Tibetan Empire and was defeated. He was removed from his post soon thereafter, and while he would return to imperial service, he would never regain the power he had.
