安慶緒
In 755, when An Lushan rebelled at his post at Fanyang Circuit (范陽, headquartered in modern Beijing), An Qingxu was apparently with his father and accompanied his father south. In response to An Lushan's rebellion, An Qingxu's mother Lady Kang and older brother An Qingzong (安慶宗), then at Chang'an, were executed, and after An Lushan captured Chenliu Commandery (陳留, roughly modern Kaifeng, Henan), it was An Qingxu who realized that An Qingzong had been executed and who tearfully informed his father, sending his father into a rage in which he executed the Tang soldiers who surrendered to him at Chenliu.
