Du Fu
The bow should be the hardest, and the archer should shoot the longest.
Shooters should shoot horses, and leaders should catch their leaders.
There is a limit to killing people, and all countries have national boundaries.
If you can invade the mausoleum, how can you kill more?
[Remarks]:
Bow: Pull the bow.
Catch: catch and take away.
[translation]:
If you use a bow, you must use a strong bow, and if you use an arrow, you must use a long arrow. If you want to shoot the enemy, you must shoot the enemy's horse first, and if you want to catch the enemy, you must first catch the enemy's head. There should be a limit to killing people, and all countries have their own borders. As long as we can stop the enemy's aggression, is it necessary to kill more people in the war?
[Solution]:
This well-known frontier fortress poem is rhythmic, catchy and memorable.
