《三国志·魏书·满田牵郭传》
田豫认为敌船将要返回，加之天晚风急，敌人害怕风浪，漂到东边又无岸，肯定会在成山靠岸的，而成山没有藏船的地方，只能沿海岸停泊。
豫度贼船垂还，岁晚风急，必畏漂浪，东随无岸，当赴成山。
Tian Yu believed that the enemy ship was about to return, coupled with the late night and strong wind, the enemy was afraid of the wind and waves, and drifted to the east without a shore. They would definitely land at Chengshan, but there was no place to hide the ship at Chengshan, and they could only stay along the coast.
