Original text:

Riding a bike to visit the border and passing through Juyan County.

Pengpeng also floated out of Korea, and the geese heading north also flew into the sky.

The vast desert is lonely, and the Yellow River sets the yen.

When I arrived at the small pass, I met a spy waiting for the knight and told me that Dou Hu was in Yan.

Translation:

I will visit the border without pomp, and all the countries I pass by have passed by.

Like a grass drifting with the wind, wild geese belonging to the north are flying in the sky.

Lonely smoke rises to the sky in the vast desert, and the sunset is round by the Yellow River.

When I arrived at Xiaoguan, I met the reconnaissance cavalry and learned that the commander-in-chief was still at the front.

The first two sentences explain the purpose and place of this trip and why you wrote this poem; Zhuan Xu's two sentences contain multiple meanings, and the feeling of borrowing grass to write down; The two sentences of the neck couplet describe the magnificent scene of the frontier desert, with a vast realm and magnificent weather. The end couplet wrote frontier fortress, but I didn't see the general officer. The scout told the special envoy that the first general was at the front. This poem not only reflects the frontier life, but also expresses the feelings of loneliness, loneliness and sadness caused by the exclusion of the poet, as well as the generous and tragic feelings caused by the emotion being edified, purified and sublimated in the majestic scenery of the desert, showing an open-minded feeling.
