Whose poem is "Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned"?

"Yellow sand is covered with shining armor, but the broken loulan is not returned" comes from Wang Changling's poem (Tang Dynasty).

The soldiers on the border have been through many battles, their armor is worn out, their ambitions are immortal, and they will never return home until they defeat the invading enemy.

Note: Break: One is "chop". Loulan: The name of the Western Regions in Han Dynasty, namely Shanshan Kingdom, is located in the southeast of Shanshan County, Xinjiang Uygur Autonomous Region. King Loulan of the Western Han Dynasty communicated with Xiongnu and killed the envoys of the Han Dynasty who communicated with the Western Regions many times. Here, it generally refers to the minority regimes that often invaded the border areas in the northwest of the Tang Dynasty. Never Return: A work of "never return".

Original text:

There is a dark snow-capped mountain in Qinghai, with long white clouds and a lonely city looking at Yumenguan.

Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned.

Translation:

Qinghai Lake is covered with dark clouds, and the continuous snow-capped mountains are bleak. Yumen, the ancient city of frontier fortress, is a grand pass, thousands of miles away, facing each other from afar.

The soldiers guarding the border have been through many battles, their armor is worn out, their ambitions are immortal, and they will never return to their hometown until they defeat the invading enemy.

Readers of frontier fortress in Tang Dynasty are often confused by the ancient and modern miscellaneous names and spatial separation involved in poems. Some people doubt that the author is not familiar with geography, so they don't seek a good solution, and others write for it. This is the case with this poem.
