Bright moon in Qin dynasty/off in Han dynasty/,
Long March/people have not returned/.
But let Longcheng/Jiang Fei/in,
Don't teach/Huma/Duyinshan/.
Since the Qin and Han Dynasties, Yue Ming has left home for an expedition to Wan Li, and the soldiers have not returned yet. If Wei Qing, who attacked Liuzhou, and General Li Guang, who flew in, were still there, the enemy would not be allowed to cross the Yinshan Mountain.
Appreciation of works: This is a famous frontier fortress poem, which shows the poet's hope to be a good general, to quell the frontier fortress war as soon as possible and let the people live a stable life. Most people regard frontier fortress as a way to become famous. Some intellectuals, most of them have frontier life experience, and their poems mainly describe frontier life, forming the so-called "frontier poetry school". The poet begins with a description of the scenery, and the first sentence outlines a desolate scene of Leng Yue looking at the border. "The Moon of Qin Dynasty was broken in Han Dynasty" cannot be understood as the Moon of Qin Dynasty was broken in Han Dynasty. Here, Qin, Han, Guan and Yue are used alternately, which is called intertextuality in rhetoric, meaning bright moon in Qin and Han dynasties and Guan in Qin and Han dynasties. "The moon was bright in Qin Dynasty, but closed in Han Dynasty". The bright moon was in the sky, shining on Wan Li frontier fortress, showing the vastness of frontier fortress and the depression of scenery. In front of the "Moon" and "Pass", it is decorated with "Qin and Han Dynasties", which has a higher artistic conception and leads us to distant ancient times, which is even more thought-provoking: the border war has been continuous since Qin and Han Dynasties and has continued until now, which has really dragged on for too long! This is a description of the long history of frontier fortress in Time. The poet hinted that the war here has never stopped since Qin and Han dynasties, highlighting the long time. The second sentence "The Long March has not yet returned" and "Wan Li" mean that the frontier fortress and the mainland are far from Wan Li. Although it is empty, it highlights the vastness of space. The Return of Man reminds people of the disaster brought by the war and expresses the poet's grief and indignation.
