Liangzhou song

The Ring of Wang Tang (688-742)

The Yellow River is getting farther and farther away, because it flows in the middle of the Yellow River, and Yumenguan is located on a lonely mountain.

Why use the elegy of willow to complain about the delay of spring, old Yumenguan, a spring breeze is not blowing!

Biedongda

(Tang) Gao Shi

A thousand miles away in Huang Yun,

The north wind blows goose feathers and heavy snow one after another.

Mochow has no bosom friend in the future,

Who doesn't know you in the world?

Border songs

Gaoshi

End floating clouds and join the army. And with the anger of the prince, rely on the male of the general.

Thousands of drums and thunder, thousands of flags and fires. Sun gear is in frost, and the moon hangs a bow.

Qinghai cloud turns, and Montenegro soldiers rush. The war is too high and too high, and the head is empty after the war.

Wan Li is willing to die, but once he succeeds. Draw a picture of Kirin Pavilion and enter Mingguang Palace.

Smile and say to the scribes: once you were poor! The ancients did not know this and often became old people.

Judging from the style, artistic conception and author of these poems, they are obviously frontier poems.
