Prefect of Lüeyang, Yan Shu (嚴舒), wanted to have Ma Long's position as Prefect of Xiping. Using his close connection to the powerful minister, Yang Jun, he slandered Ma Long to Yang Jun, claiming that he was too old and senile, and thus no longer fit for his position. He was recalled to the capital while Yan Shu was given his position. However, the Qiang and Di people soon began gathering in large numbers. The inhabitants of Longyou were startled, and the court feared that another rebellion was going to break out. Therefore, Ma Long was reinstated as Prefect of Xiping, and he would hold the office up to his death. References Fang, Xuanling (ed.) (648). Book of Jin (Jin Shu). Sima, Guang (1084). Zizhi Tongjian.
