Yuan Zai
Early in the "Tianbao" era (742–756) of Emperor Xuanzong, Emperor Xuanzong began to favor Taoism, and he scheduled a special examination for scholars well-versed in the "Zhuangzi", "Laozi", "Liezi", and "Wenzi". Yuan Zai did well on this special examination and was made the sheriff of Xinping County (新平, in modern Xianyang, Shaanxi). When the imperial censor Wei Yi (韋縊) was put in charge of selecting officials from Qianzhong Circuit (黔中, roughly modern Guizhou and western Hunan), he invited Yuan to serve as his assistant. After Yuan became better known, he was promoted to be "Dali Pingshi" (大理評事), a secretary at the supreme court (大理寺, "Dali Si"). Later, when the official Miao Jinqing served as the official in charge of the eastern capital Luoyang, he also invited Yuan to serve as his assistant. After that term of service, Yuan became "Dali Sizhi" (大理司直), a junior judge at the supreme court.
