A tragic poem about war

If you die in battle, you will be urged to drink pipa immediately, and you will not laugh if you are drunk in battle. In ancient times, several people went back to the dark snow-capped mountains in Changyun, Qinghai, and looked at the yellow sand in Yumenguan, the lonely city, wearing golden armor and fighting hundreds of battles. If you don't break Loulan, you will never return to chase them with us and go into battle with horses lightly. Our bows and swords were covered with snow, people were sleepy, and the general was white-haired and in tears.
