《隋书·列传·卷二十七》
皇上想治理天下，不要忘记了兴废之事。如说是优待老臣，崇尚长者，自可多赐金帛；如让当州郡长官，所带来的损失就很大了。
至尊思治，无忘寝兴，如谓优老尚年，自可厚赐金帛，若令刺举，所损殊大。
Your Majesty wants to govern the world, so don't forget to keep in mind the lessons of rise and decline. If you just want to reward old officials and esteem the elderly, you can simply give them more money and silk as gifts. But if you put them in positions of governor or prefect, the losses will be too great.
