《旧唐书·列传·卷九十二》
何况王廷凑品行卑劣，没有承继父祖的资质；成德军同朝廷分离，又加重了胁迫的局势。
况廷凑阘茸，不席父祖之资；成德分离，又多迫胁之势。
Moreover, Wang Tingecou is a person of inferior character and does not have the qualities of his father and grandfather; the Chengde army is separated from the imperial court, which further aggravates the situation of coercion.
