BY TU FU

When bows are bent, they should be bent strongly;
When arrows are used, they should be long,
The bow-men should first shoot the horses.
In taking the enemy prisoner, the Leader should first be taken;
There should be no limit to the killing of men.
In making a kingdom, there must naturally be a boundary.
If it were possible to regulate usurpation,
Would so many be killed and wounded?
