Jia Su

Jia Su (賈餗) (died December 17, 835), courtesy name Zimei (子美), formally the Baron of Guzang (姑臧男), was an official of the Chinese dynasty Tang Dynasty, serving briefly as a chancellor during the reign of Emperor Wenzong. During Emperor Wenzong's reign, he became involved in a major power struggle between imperial officials and eunuchs known as the Ganlu Incident, and he was killed by the eunuchs along with three other chancellors, Li Xun, Wang Ya, and Shu Yuanyu.

It is not known when Jia Su was born, but it is known that his family was from Henan Municipality (河南, i.e., the region of the Tang Dynasty eastern capital Luoyang). His family was originally from Guzang (姑臧, in modern Wuwei, Gansu). His grandfather's name was Jia Zhou (賈冑), and his father's name was Jia Ning (賈寧), and neither was listed with an office in the table of the chancellors' family trees in the New Book of Tang, suggesting that they were commoners. Jia Su had at least one older brother, Jia Song (賈竦).

It was said that Jia Su lost his father early in life and travelled in the region between the Yangtze River and the Huai River. When his uncle Jia Quan (賈全) became the governor of Zhedong Circuit (浙東, headquartered in modern Shaoxing, Zhejiang), Jia Su went to depend on Jia Quan. Jia Quan was impressed by his talents and treated him well.
