Han Yuefu's poem "Drinking Horses in the Great Wall Grottoes" says: Guests come from afar and leave me a pair of carp. Tell the boy to open the wooden box and write a letter with a ruler. Later, I wrote a distant letter with double carp.
Zhuang Zhou Mengdie: The language comes from Zhuangzi? The Theory of Everything: In the past, Zhuang Zhoumeng was a Hu (butterfly), a lifelike Hu (butterfly). I don't know what day it is. If you suddenly feel it, you will suddenly feel it. I wonder if Zhou Zhimeng is a butterfly? What is Hu's dream for Zhou He? There must be a difference between Zhou and Hu (butterfly). This is called materialization. Zhuangzi used this to illustrate the idea that all things are one and all things are equal. Later, scholars used it to instruct people's confused dreams and fickle things. For example, Lu You's poem "Winter Night" says: A cup of poppy is a slave, and butterflies in Zhuang Zhou are both empty.
Goose: Loneliness, homesickness, homesickness, tidings and news.
Hongyan: Letters miss relatives.
Hongyan is a large migratory bird, which moves southward every autumn, often causing homesickness and wandering sorrow.
For example, Xue Daoheng, a native of the Sui Dynasty, wrote "People miss home every day": geese fly over flowers, and people think before. I had the idea of going home long before the flowers bloomed. But when the geese returned to the north, people had not returned home. When the poet was an official in the Northern Dynasties, he sent an envoy to the Southern Dynasties and wrote this homesick poem in a subtle and tactful way.
There are also people who write about geese, homesick at night, sick during the New Year (Ouyang Xiu's play answers Yuan Zhen), broken stars and counting geese, the flute leaning against the building (Zhao Tuo's "Looking at Autumn in Chang 'an" in the Tang Dynasty), the blue pool stars are cold, and the swan geese are sad and red (Dai Song Fugu Moonlight Boat).
There are also letters referred to by Hongyan. Everyone is familiar with the allusions of Hongyan biography, and the application of Hongyan as a messenger in poetry is also very common. For example, plucking the hair of a wild goose, River Water (To Li Bai at the End of the Sky by Du Fu), Shuo Yan's Calligraphy and Huang Xiang's Tears (Li Si by Li Shangyin).
Partridge bird: the image of partridge also has a specific connotation in ancient poetry. The partridge's singing makes people sound like brothers, which is very easy to evoke the association of hard journey, sadness and parting. As the sun sets in autumn, the grass is blooming and the partridges are far away (Li Qunyu, a poet in the Tang Dynasty, smells partridges on Jiuzipo), and in the evening, the river is full of gloomy clouds and the partridges are heard in the depths of the mountains (Xin Qiji, Bodhisattva Xia? The partridge in the poem is not a bird in a purely objective sense.
Cicada: Cicada will not live long after autumn. After some autumn rains, cicadas will make a few intermittent moans, and their lives are at stake. Therefore, chilling has become synonymous with sadness.
For example, the first two sentences of Dondero's "Chanting the Cicadas": the cicadas in the west sing, and the guests in the south think. [Journey to the West: Autumn] Singing in a chilling voice exaggerates his deep homesickness in prison. Liu Yong, a poet in the Song Dynasty, begins with the following words: Cold cicadas are sad, pavilions are late, and showers begin to rest. Parting is not directly described, and the feeling of sadness is full of readers' hearts, brewing an atmosphere that can touch parting. Cao Zhi, a figure of the Three Kingdoms, also expressed this feeling in poems such as "White Horse Going to Wang Biao".
Yuanyang refers to a loving couple, who would rather be Yuanyang when they are immortal (the ancient meaning of Lu to Chang 'an in Tang Dynasty).
