Don Wang Changling's Out of the Fortress

It is still the moon and border pass in Qin and Han dynasties, and the enemy has fought a protracted war. If Wei Qing, who attacked Longcheng, and Li Guang, the flying general, were alive today, the Huns would not be allowed to go south to spend their horses in Yinshan.

Translation:

The bright moon is still the bright moon since ancient times, and the border crossing is still the border crossing since ancient times. Only those soldiers who are far away from home and have been stationed at the border for a long time have not returned. If a general like Li Guang is still here. The enemy will never dare to invade us again.
