What is the function of lyric sentences in poetry?

These two sentences, through the elaboration of the scenery, arouse women's feelings and thoughts about their husbands who are far away from home.

At the beginning of the poem, there are green people and "Philip Burkart Road"; Then he said, "it's incredible to be far away", and meeting in a dream is more real; "Dreams are all around", but suddenly I feel that my dreams are empty, so I return to acacia. In the eight sentences, after several twists and turns, her feelings are in a trance, her images are blurred and unpredictable, which fully shows her lingering and passionate feelings.

The idea of women written in the poem is like a dream, but it is not true. Just like the story in the poem, someone in his family came back and received a "double carp" and a "book with a ruler in it", which may be true or an imaginary image when I miss him very much. It is legendary to dissect a fish and read a book, and it makes sense for a wanderer to write a book.

This is a Yuefu poem in Han Dynasty, which was first seen in Selected Works of Zhaoming, entitled Yuefu Ancient Poems. Shan Li noted: "This is an ancient poem, and I don't know the author's name. He is always like this. "

"Notes on Selected Works and Five Ministers" said: "The Great Wall was built by Qin Wei. There is a spring hole below, where you can drink horses. The road to recruiting people is also sad. It is said that the conscription system in the world is not finished, and the hostess thinks about her husband and pretends to be okay. "

The Great Wall was built by the State of Qin to resist the Huns. There is a spring hole at the foot of the mountain where you can drink horses. Passers-by of the expedition felt sorry for this. The conscription system and the war in the world are not over yet, and the women in the family miss their husbands on the expedition, so they created the article "Drinking Horses in the Great Wall Cave".
