What is a poem for the emperor?

Batavia on Yanmenguan Line

Author: Li He

Enemy soldiers rolled in like dark clouds in an attempt to tear down the city wall; Our army was ready, and the sun shone on the armor, glittering with gold.

In autumn, the loud bugle sounded; The soldier's blood became dark in the night.

The red flag rolled half, and the reinforcements rushed to Xiao; The night frost is heavy and the drums are gloomy.

I want to report to you on the golden platform, and I want to take Yulong to your death.
