Lü Yin

Lü Yin (呂諲) (712–762), formally Count Su of Xuchang (須昌肅伯), was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Suzong. Historians often regarded him as being more capable as a regional governor, later in his career, than as a chancellor.

Lü Yin was born in 712, around the time when Emperor Xuanzong became emperor. His family was from Pu Prefecture (蒲州, roughly modern Yuncheng, Shanxi) and traced its ancestry to the ruling Jiang clan of Qi during the Spring and Autumn period. Lü himself was said to be ambitious and studious in his youth, but was poor and could not support himself. A wealthy man from his locale, Cheng Chubin (程楚賔) was impressed with Lü's talent and believed that he would one day be successful, and Cheng decided to give his daughter to Lü in marriage. After the marriage, both Cheng Chubin and his son Cheng Zhen (程震) supported Lü financially, allowing Lü to visit the Tang Dynasty capital Chang'an.

Early in Emperor Xuanzong's Tianbao era (742-756), Lü passed the imperial examinations and was made the sheriff of Ningling County. The surveyor of the circuit, Wei Zhi (韋陟), was impressed with Lü's talent and recommended him to serve as deputy surveyor. Later, Geshu Han, the military governor (jiedushi) of Longyou (隴右, headquartered in modern Haidong Prefecture, Qinghai) and Hexi (河西, headquartered in modern Wuwei, Gansu) Circuits invited him to serve on staff as treasurer. While serving under Geshu, it was said that Lü was careful and hardworking, and at times, when his colleagues would be spending time out of the office, Lü would be in his office to review the files. This diligence caused Geshu to favor him more.
