《宋史·列传·卷四十》
起先，张咏在成都，听说寇准当宰相，对自己的僚属说： 寇公是奇才，可惜学问与权术不够。 等到寇准出使陕州，张咏恰好从成都罢职回来，寇准尊敬地供给帐幕，热情款待。
初，张咏在成都，闻准入相，谓其僚属曰： 寇公奇材，惜学术不足尔。 及准出陕，咏适自成都罢还，准严供帐，大为具待。
At first, Zhang Yong was in Chengdu, and when he heard that Kou Zhun became prime minister, he said to his colleagues: "Kou Gong is a genius, it's a pity that he is not good enough at study and politics." When Kou Zhun was sent to Shaanzhou, Zhang Yong happened to return from Chengdu, where he was dismissed. Kou Zhun respectfully provided tents and took good care of him.
