《资治通鉴·唐纪·唐纪五十七》
现在，虽然国库的财物尚有结余，但愿陛下爱惜，万一天下发生不测事件，就可动用国库，而不致使官吏再重税搜刮百姓。 
虽内藏有馀，愿陛下爱之，万一四方有事，不复使有司重敛百姓。 
At present, though the national treasury has a surplus, I hope that Your Majesty will be prudent. In case of unexpected events that threaten the nation, the national treasury can be utilized, so that officials won't have to resort to heavy taxation and exploitation of the people.
