《后汉书·列传·刘虞公孙瓚陶谦列传》
兵法上说百楼不攻，如今我各营楼台千里，积蓄谷物三百万斛，有这些吃的就足以等待天下的变化。
兵法百楼不攻。今吾诸营楼樐千里，积谷三百万斛，食此足以待天下之变。 
The Art of War says that a hundred towers cannot be attacked. Now my camps and towers are thousands of miles away, and I have accumulated three million bushels of grain. With this food, I can wait for the changes in the world.
