《孙子兵法·作战篇》
孙子说：用兵作战，一般要出动战车千乘，运输车千辆，集结士兵十万，沿途千里转运粮草。这样国内外的各种费用开支，招待使节、策士的用度，维修作战器械的胶、漆等材料费用，保养战车、甲胄的支出等，每天都要耗费数额巨大的资金。作好了这些准备后，十万大军才能出动啊！
孙子曰：凡用兵之法，驰车千驷，革车千乘，带甲十万，千里馈粮，则内外之费，宾客之用，胶漆之材，车甲之奉，日费千金，然后十万之师举矣。
Sun Tzu said: In using soldiers in combat, you must generally mobilize a thousand chariots, a thousand transport carts, gather an army of a hundred thousand soldiers, and transport military supplies over a thousand li. In this way, various kinds of expenses at home and abroad, the cost of receiving envoys and strategists, the cost of materials such as glue and lacquer for repairing combat equipment, and the cost of maintaining chariots and armor, etc., will use up a huge amount of money each day. After all these preparations have been made, an army of a hundred thousand can be mobilized!
