What are the ancient poems describing the frontier troops, such as "leaving the Great Wall"? Thank you, everyone.

From the army to Wang Changling, Qinghai, where the clouds are long and the snow mountains are dark, the lonely city looks at Yumenguan. Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned. When I left Wang Changling, the moon set in Qin and the Long March people didn't return. But I let Longcheng fly. I didn't teach Huma to cross the Yinshan Mountain ... Yang Jiong went to Xijing with a bonfire, and he was not satisfied. I have a bow and a phoenix que, and an iron horse rides around Longcheng. The snow is dark and the flag is carved, and the wind is ringing. Being a centurion is better than being a scholar. Chen Tao vowed to sweep the Huns in Longxi. Five thousand sable brocade in memory of Chen Hu. Poor bones by the wuding river, still living a dream. Liangzhou Ci Wang Hantao wine luminous cup, want to drink pipa immediately. Drunk in the battlefield, you don't laugh. You fought several wars in ancient times. Xia Sai bends Wang Changling to drink, my horse, and cross the autumn water! When we watch the sunset on the sandy plain, the stream is cold, the wind is like a sword, and the distant place, the vague ancient battle of Lintao, started by those long city walls, was once the pride of all. The imperial city is full of ancient times, and the bones are messy. Join the army to levy snow in the northern Tianshan Mountains of Yi Li.
