Tang chancellor and cousin of Yang Guifei, killed during An Lushan Rebellion.
Compare Yang Guozhong with another historical figure:
Yang Guozhong was appointed Chancellor under Emperor Xuanzong, replacing the deceased Li Linfu. He was the cousin of Yang Guifei, the emperor's favorite consort, and his rise was due to family connections rather than merit.
Yang Guozhong repeatedly antagonized An Lushan, accusing him of plotting rebellion and raiding his mansion in Chang'an. These actions, combined with An's fear of being purged, accelerated the outbreak of the An Lushan Rebellion in 755.
Yang Guozhong forced the Tang general Geshu Han to engage An Lushan's forces at Tong Pass, despite Geshu's advice to hold the defensive position. The Tang army was defeated, and the pass fell, opening the way to Chang'an.
As Emperor Xuanzong fled Chang'an after the fall of Tong Pass, mutinous soldiers at Mawei Station blamed Yang Guozhong for the disaster. They killed him and forced the emperor to order the death of Yang Guifei.
