《宋史·列传·卷六十九》
真宗十分喜悦。李迪又说 ：陛下东封泰山时，下敕令所过之处不要砍伐树木清除道路，将驿舍或州治的官署作为行宫，仅仅派人修饰休息罢了。
又言： 陛下东封时，敕所过毋伐木除道，即驿舍或州治为行宫，裁令加涂塈而已。
Zhenzong was very happy. Li Di also said: When Your Majesty visited Mount Tai in the east, he ordered that no trees should be cut down or roads cleared along the way. Instead, official offices in post houses or states were used as temporary palaces, and people were simply sent to repair the facilities.
