《宋史·列传·卷一百四十二》
虞允文看到金人大量运输粮草，建造战舰，便向金主告辞回去，完颜亮说 ：我准备去洛阳观赏牡丹花。 虞允文回来后，将自己在金国见到的备战情况及完颜亮的言行立即上奏告知皇上，再次强调必须加强淮、海两地的防御力量。
允文见运粮造舟者多，辞归，亮曰： 我将看花洛阳。 允文还，奏所见及亮语，申言淮、海之备。
Yu Yunwen saw that the Jurchens were transporting a lot of food and building warships, so he bid farewell to the Jin sovereign and went back. Wanyan Liang said: I am going to Luoyang to appreciate the peonies. After Yu Yunwen returned, he immediately reported to the emperor what he had seen and heard about the Jin’s preparation for war, and emphasized again the importance of strengthening the defense strength in Huai and Hai.
