《新唐书·列传·卷一百四十八》
此时，兵屯于河南、河北，战事相持不下，财政十分紧张，仅军事所需，每月约一百多万缗，府库里的钱仅够支付三个月。
是时兵屯河南、北，挐不解，财用日急。于是度支条军所仰给，月费缗百馀万，而藏钱才支三月。
At this time, the troops were stationed in Henan and Hebei, and the battle was deadlocked. The finances were very紧张. The military alone needed about 1 million yuan each month, and the money in the treasury was only enough to pay for three months.
