"A cup of dirty wine can lead to a home thousands of miles away, but Yan Ran has no plan to return" is borrowed from the allusion of "Feng Yanran Mountain Inscription": In the first year of Emperor Yongyuan of the Eastern Han Dynasty, the cavalry general Dou Xian made the Northern Expedition After the Xiongnu were defeated, they carved stones on Yanran Mountain in Mobei to record their merits. Ban Gu wrote and praised the mighty virtues of the Han Dynasty. This is the so-called "Stone Yanran". These two sentences describe the contradiction between guarding the border and returning home, reflecting the deep sadness. "One cup" is opposite to "thousands of miles", which expresses the lack of wine and the distance from home, depicting the feeling of "raising a glass to relieve sorrow and sorrow will become more sorrowful"; and then writes about the sense of responsibility of the soldiers guarding the border and defending the country, and the unstoppable longing for it. Contradiction, this contradiction is inextricable, and truly reflects the thoughts and feelings of the border guards.
