《宋史·列传·卷九十六》
皇帝圣性未定，见节俭则节俭，见奢侈则奢侈，所以训导成德，举止应该有制可依。
皇帝圣性未定，睹俭则俭，睹奢则奢，所以训导成德者，动宜有法。
The emperor's nature is not yet stable. If he sees thriftiness, he will behave thriftily; if he sees extravagance, he will behave extravagantly. Therefore, in teaching and shaping his character, you must impose some order on his behavior.
