During the group activity of studying the topic of "Meteorology and Phenology", Xiao Ming discovered that there are many poems about "wild geese" and "swallows" in ancient poems.

Goose is a large migratory bird that migrates south every autumn, often causing travelers to feel homesick for their loved ones and sad to travel. For example, Xue Daoheng of the Sui Dynasty wrote in "Everyone Thinks of Returning Home": "When people return home after the geese have fallen, their thoughts are in front of the flowers." Long before the flowers bloom, people have the idea of ??returning home; but when the geese have returned north, people have not yet returned home. . When the poet was an official in the Northern Dynasty, he went to Chen as an envoy to the Southern Dynasty and wrote this poem about returning home, which is implicit and tactful. Others who use wild geese to write thoughts include "I hear the returning geese at night and miss each other, and I feel the splendor of things in the new year when I am sick" (Ouyang Xiu's "Playing Reply to Yuan Zhen"), "The remaining stars are counting the wild geese across the block, and the sound of the flute makes people lean on the building" (Zhao Gu of the Tang Dynasty) "Autumn Look at Chang'an") etc. There are also swan geese used to refer to letters. Everyone is familiar with the allusion of Hongyan sending letters, and the use of Hongyan as a messenger to deliver letters is also common in poetry. For example, "When will the swan geese arrive, the river will be flooded with autumn water" (Du Fu's "The End of the Day with Li Bai") and so on.

Swallows are migratory birds that migrate with the seasons. They like to stay in pairs and stay in other people's houses or under the eaves. It often appears in ancient poetry, and is especially favored by the ancients. It has rich imagery: it may cherish the spring and mourn the autumn, or exaggerate the sorrow of separation, or express lovesickness, or express sentiments about current events.

For example, "The Book of Songs·Beifeng·Yanyan":

The swallow is flying, and its feathers are missing. The son returned home and was sent far away into the wild. I can't even look forward to it, and I cry like rain.

The swallows are flying, and they are flying. When his son returns, he will be far away from him. Looking beyond the reach, benevolent and weeping.

The swallow is flying, and its sound is rising from below. His son returned home and was sent far to the south. Looking beyond my reach, it really works my heart.

Zhong’s heart is blocked if he is left alone. He is gentle and helpful at the end, and he is careful about his body. The thought of the first emperor is to exploit the few people.

This poem is the earliest farewell poem in China and has an important influence on the development of farewell poems for future generations. In this poem, the image of swallows conveys a sense of separation and sadness. The first three chapters of the poem are all about flying swallows. "Swallows are flying" sets off the reluctant atmosphere of parting in the whole poem. It uses happy scenes to describe sadness, and uses the freedom and joy of swallows flying together to contrast the parting. of sadness. This makes us sigh with emotion that even swallows are so full of deep emotions, let alone people.

With the development of poetry, its meaning is more abundantly reflected in poetry. Poems such as "Thinking of two flying swallows, carrying the mud nest of the king's house" in "Nineteen Ancient Poems: The East City is High and Long", use the beautiful poem of the flying swallows carrying the mud nest house to convey the deep affection of the poet's eternal marriage as husband and wife. , Zhu Jun said in "Nineteen Ancient Poems" that "the knot is so detached and ethereal that he has described all the affairs of talented men and beautiful ladies from ten thousand generations."
