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.
Before serving as 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.
