At the beginning of this poem, "The Pride of the Fisherman", why did the author write about autumn scenery and flying away?

Yuminao

fan zhongyan

The scenery in Qiu Lai is different, and Hengyang Goose is unknown. Around, the sound of the horn sounded, thousands of miles away, and the long smoke closed.

A glass of turbid wine is Wan Li's home, but Ran Yan hasn't come home yet. Qiang tube covered with frost, people do not sleep. The general was white-haired and in tears.

The first sentence is "Qiu Lai has different scenery", and "Xiaxia" refers to the whole Yanzhou area. At that time, Yanzhou was the northwest frontier and the military center to prevent the Xixia attack, so it was called "Xixia". "Qiu Lai" indicates the seasons. "Different Scenery" summarizes the different scenery of Yanzhou and the mainland in autumn. The author uses a word "different" to summarize the difference of seasonal changes between the north and the south, which contains the meaning of surprise.

"Hengyang Goose went without paying attention." Wild geese are migratory birds. Every autumn, the geese in the north fly to the south to avoid the cold. According to legend, the Yan Hui Peak in Hengshan Mountain was named after the geese flew south to Hengyang, so Wang Bo said, "The cold was shocked by the cold, and the Hengyang pool was broken by the sound" (Preface to Wang Tengting). The word "Hengyang flying geese" also comes from this legend. "Inattention" means that the wild geese here spread their wings to the south in autumn, without nostalgia, which reflects that this area is bleak and desolate in autumn.
