What kind of artistic conception do these two sentences describe?

The sentence "The bright moon in the Qin Dynasty was closed when the Han Dynasty was closed, and the Long March did not return" was magnificent, full of the desolate and vast feeling of frontier fortress scenery and the heavy feeling of crossing the historical dust, which implied the grief and indignation over the unfinished war. The poet adopted the rhetorical device of intertextuality.

The alternate use of Qin, Han, Guan and Yue is not limited to "bright moon in Qin" and "Guan in Han", but refers to the moon in Qin and Han dynasties and the Guan in Qin and Han dynasties. In this way, the lonely frontier scenery with high mountains and high moons, under the poet's brush strokes, injected a heavy sense of history into the desolation, and the artistic conception was more vigorous and far-reaching.

In addition to highlighting the heavy sense of history in time, the poet also uses the comparison between the "Long March" and "People have not returned" to convey a broad sense of space, which makes the poet's grief and indignation over the unsettled war more profound and his artistic conception more tragic and generous. From the Qin and Han Dynasties to the Tang Dynasty, it was very sad to think of those heroes who died but didn't return.

"The moon was bright in Qin, closed in Han, and the Long March did not return." This kind of love-hate relationship across time and space makes the artistic conception of poetry more vigorous and deep. Therefore, when the last sentence "Only make the Dragon City fly, don't teach Huma to spend the shadow of the mountain" rushed out, the poet's ridicule on the incompetence and incompetence of the current rulers was even more powerful and intriguing.

Extended data

This is a famous frontier fortress poem, which expresses the poet's desire to be a good general, calm the frontier fortress war as soon as possible and let the people live a stable life.

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 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 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.
