《旧五代史·后唐·末帝纪上》
到末帝镇守河中时，安重诲知道他经常出入州城，便假托君命告诉牙将杨彦温，令他遇上末帝出城后就关闭城门不让他进来。
及帝镇河中，重诲知其出入不时，因矫宣中旨，令牙将杨彦温遇出郭则闭门勿纳。
When the Last Emperor was stationed in Hezhong, An Chonggui learnt that he often left the city. He then falsely said that the Emperor had ordered General Yang Yanwen to close the city gate when he happened to see the Last Emperor going out of the city and not let him back in.
