《资治通鉴·隋纪·隋纪七》
裴蕴知道炀帝的心意，就让河南平民张行本上奏说： 苏威从前在高阳掌管挑选官员之事时，他滥授官职，畏惧突厥，要求返回京师。 
蕴知帝意，遣河南白衣张行本奏： 威昔在高阳典选，滥授人官；畏怯突厥，请还京师。 
Pei Yun understood Emperor Yang's intentions, so he had a civilian from Henan, Zhang Xingben, submit a memorial that said: When Su Wei was in charge of selecting officials in Gaoyang, he abused his power to issue official titles, feared the Turks, and asked to return and serve the imperial court.
