The cultural connotation of wild geese in ancient poetry is (1) to express the homesickness of wanderers, such as Fan Zhongyan's: The scenery is different when autumn comes under the fortress, but Hengyang goes without noticing the wild geese. (2) Another cultural connotation of Yan is letters, the most obvious manifestation of which is Wang Wan's "Under the Cibeigu Mountain": Where can the hometown letters be reached, by the Luoyang side of Yan.
1. Homesickness: The scenery in the fortress is different when autumn comes, but the geese in Hengyang leave without noticing
1. Translation: Autumn is here, and the scenery in the northwest frontier fortress is different from that in the south of the Yangtze River. The wild geese flew back to Hengyang again, with no intention of stopping at all.
2. Appreciation: The next two sentences first point out the location, time and the different scenery of Yanzhou in the border area and the mainland. Secondly, they describe the difference in scenery in detail. The climate in the northwest frontier is cold. In autumn, it is cold. The wind was blowing coldly, and everything was desolate. The wild geese were flying south with no intention of nostalgia. The combination of movement and stillness shows a chilling battlefield scenery picture, vividly depicting the unique scenery of the Border Sea.
2. Letters: Where can I get my hometown letters? Return to Yanluoyang.
1. Translation: I don’t know when the letter sent home will arrive. I hope that the wild geese returning from the north will take it to Luoyang.
2. Appreciation: As the sun rises over the sea and spring begins to stir, the poet sets his boat on the green water and continues to sail towards the guest road beyond the green mountains. At this time, a group of geese returning from the north were flying across the clear sky. Yan'er was about to pass through Luoyang. The poet remembered the story of "the wild goose's feet passing the message". The wild goose asked you to send greetings to my family when you flew over Luoyang.
These two sentences closely follow the three couplets and echo the first couplet. The whole article is enveloped in a faint layer of nostalgia.
