《魏书·列传·卷二十四》
不久使者黎明时突然来到，守渡口的官吏想先禀告李式，使者欺骗说： 我需要南渡，不在此州停留，不烦劳告诉尊刺史。 
既而使人平晓卒至，津吏欲先告式，使者绐云： 我须南过，不停此州，不烦令刺史知也。 
Shortly afterwards, the envoy arrived suddenly at dawn. The officer in charge of guarding the ferry wanted to report to Li Shi first, but the envoy deceived him, saying: “I need to cross [the river] to the south. I will not stop in this prefecture, so there is no need to trouble His Excellency the governor.”
