《资治通鉴·晋纪·晋纪三十六》
在将要攻下城墙的时候，慕容熙命令手下的将士说： 不得抢先登城，等到把城墙铲成平地的时候，我跟皇后坐在车上一同进城。 因此，城中得到喘息的机会，加强了防备，于是他们没法攻破，只好回去了。
城且陷，熙命将士： 毋得先登，俟铲平其城，朕与皇后乘辇而入。 ，由是城中得严备，卒不克而还。
When they were about to capture the city walls, Murong Xi ordered his soldiers, “Do not rush to climb the walls. When the walls are razed to the ground, I will ride into the city in a carriage with the Empress.” As a result, the people in the city had a chance to catch their breath and strengthen their defenses. So they were unable to capture the city and had to return.
