《资治通鉴·唐纪·唐纪四十六》
当时，杨怀宾的儿子杨朝晟在李怀光军中担任右厢兵马使，他听说此事以后，哭泣着向李怀光禀告说： 我的父亲杀张昕为国家立下了功劳，我作为他的儿子应当遭受处罚，不可以掌管军事。 
时杨怀宾子朝晟在怀光军中为右厢兵马使，闻之，泣白怀光曰： 父立功于国，子当诛夷，不可典兵。 
At that time, Yang Huaibin's son, Yang Chaosheng, was the right-wing commander in Li Huaiguang's army. When he heard about this, he wept and reported to Li Huaiguang, saying: "My father made contributions to the country by killing Zhang Xin. As his son, I should be punished and should not be in charge of the military."
