《资治通鉴·汉纪·汉纪五十三》
如今，我的军队分驻各楼，有深堑高楼数十重，存粮食三百万斛，吃尽这些粮食，足可以看到天下局势的变化了。 
今吾诸营楼橹数十重，积谷三百万斛。食尽此谷，足以待天下之事矣。 
Now, my army occupies each of the towers. There are over a dozen meters of high, wide moats and three million bushels of grain in storage. It will be a long time before we run out of food. In the meantime, we can observe the changes on the national scene.
