What are the ancient poems in Princess Zhu Huan that the emperor asked the swallow to recite and copy 100 times?

"An Ancient Warsong" by Li Qi

During the day, the beacon tower climbing the mountain observes and gives an alarm, and at night, the horse leads the horse to the riverside.

The dark wind blew bursts of sounds, like the pipa of a princess in the Han Dynasty, full of hidden grievances.

Camp in Wan Li without battlements until the thick sky joins the vast desert in the snow.

The sorrowful Hu Yanyan flew through the air, and HUS soldiers were all in tears.

It is said that Yumenguan has blocked the road, so the soldiers can only follow the general around.

The bones of death are buried in the wilderness every year, and only grapes from the western regions are sent to the Han people.

Translation:

Climb the mountain during the day to observe the beacon tower alarm, and lead the horse to drink near Jiaohe River at dusk.

The yellow wind and sand came with the sound of fighting, just like the princess Pipa in the Han Dynasty was full of bitterness.

The wilderness is foggy and Wan Li has no battlements. Rain and snow enveloped the boundless desert.

The wailing Hu Yan flew through the air at night, and all Hu Bing shed tears.

It is said that Yumenguan has been blocked and can't go home, so the soldiers have to run with the general desperately.

Every year, the dead bones are buried in the wild, and only the grapes from the western regions are sent to the Han family.
