Zhang Jiuling
In 737, the imperial censor Zhou Ziliang () submitted an indictment against Niu, arguing that Niu should not be chancellor because he lacked talent to be chancellor, and further citing prophecies that appeared to indicate that someone named Niu would usurp the throne. Emperor Xuanzong was incensed, and had Zhou caned and exiled—and Zhou died shortly after departing Chang'an. Li Linfu then submitted an accusation against Zhang, pointing out that Zhang had recommended Zhou. Zhang was therefore demoted to be the secretary general at Jing Prefecture (荊州, roughly modern Jingzhou, Hubei). However, even after Zhang's demotion, Emperor Xuanzong still remembered his honesty, and when officials were recommended, he would often make the inquiry, "How does their honesty compare to Zhang Jiuling?" Zhang died in 740, while on a vacation in Shao Prefecture to visit his parents' tomb, and was given posthumous honors.
