First, the feelings of worrying about the country and the people and the free ambition are pinned.

? Wild geese will encounter all kinds of misfortunes and dangers in the process of seasonal migration. This naturally allows scholars to organically link the situation of geese with the situation of the lower class, place humanistic care in it, and project their vision to the sufferings of people's livelihood and national security. The idiom "Worry is everywhere" is to compare the people in distress to Du Fu's "Worry" poems such as "The Lonely Goose": "The lonely goose flies without pecking. Whoever pities a shadow will lose a million clouds. " The lonely goose is not only the embodiment of the poet, but also the epitome of the lower class who have left their homes and been displaced. Another example is Wang Mian's "Random Thoughts on Suzhou" in the Ming Dynasty: "Outside Soochow, there are traffic lights and people are half boat. How many fields are there in Daoliang today? " Care for the people cannot be expressed in words. Works that express the feelings of unfulfilled ambition through the image of Hongyan, such as Xin Qiji's "Shui Long Yin Deng Kang Xin Ting": "The sunset is on the roof, the sound is broken, and there are wanderers in the south of the Yangtze River. I saw Wu Gou, and the column was shot everywhere, and no one would attend. " Political frustration, trying to do something, made the poet fall into depression.

Second, homesickness and the sadness of friends leaving.

The ancients had a story of "Hongyan passing the book", which entrusted the grief of homesickness and wandering. Cao Pi's Miscellaneous Poems: "The grass bugs are sad, and the lonely geese are alone in the south." I am sad and miss my hometown. "In the cold autumn of depression, the poet compares himself to a lonely wild goose and expresses his deep thoughts for his hometown. Du Fu's "Returning to the Wild Goose": "A guest from Wan Li in the east will return in a few years. The wild goose in heartbroken Jiangcheng flies high in the north. "The geese have flown north, but they still live in other places. In farewell poems, the image of goose has also become one of the important emotional carriers. For example, Gao Shi's "Don't move big" says: "It is daytime in Huang Yun thousands of miles away, and the north wind blows geese and snow one after another. Mochow has no confidant in the road ahead, and no one in the world knows you. "Use the image of the wild goose to express the feeling of parting. Another example is Wang Shifu's "Righteousness": "Blue sky, yellow land, tight west wind, flying north, flying south. Whoever gets drunk in the frost forest at dawn will always leave tears for people. "With the cold autumn scenery and geese flying south to set off the sadness of parting. He Menggui's Memory of Qin E: "When you leave sadly, the geese in the south of the Yangtze River will be silent. There are absolutely no books, two lines of tears, and thousands of knots. "I'm worried that Hongyan won't pass the book, and I'm afraid Acacia won't pass it.

Third, the sense of sustenance is sad, bitter and melancholy.

This mainly focuses on personal painful experiences. For example, Li Qingzhao, a poetess in the Song Dynasty, integrated the pain of national subjugation, the pain of losing her husband and the vagaries of life into her later poems, so her works were full of sadness. Her "slow voice" can be described as tears and blood, and it is a cry for help. There is such a sentence in this poem: "The flying geese also hurt my heart, but it was an old acquaintance." Zhang Jiuling's sentimental poem in the Tang Dynasty: "I roam the boundless sky, and bird hunters crave me in vain?" Sigh the hardships and dangers of the road to official career. Another example is the Wei-Jin period in history, which is also a dark history. The shortness of life and the uncertainty of the future have infected scholars with a sad mood. Ruan Ji, for example, often writes poems with geese. "Love Poem": "Solitude calls for the wild, birds crow in the north forest." "The cold wind vibrates the hills and raises yin. Wild geese fly to Nanxiang, and birds moan. " Express inner melancholy.
