The source of this sentence is Bai Juyi's Song of Eternal Sorrow in the Tang Dynasty.
I extracted this sentence from the original text for your reference:
She sent him a message through his messenger, reminding him that only the hearts of the two of them knew the oath.
On the seventh day of July, in the Palace of Eternal Life, we secretly told each other in the quiet midnight world.
We hope to fly in heaven, two birds become one and grow on the earth, two branches of a tree. ..
The earth endures, and the sky endures; One day both will end, and this endless sadness will last forever.
This excerpt is translated into vernacular Chinese as follows:
When I left, I politely asked the messenger to send a message to the king. Only the king and I know the oath in the letter.
On the seventh day of July, in the Palace of Eternal Life, there was no one in the middle of the night, and we vowed to each other.
In heaven, I would like to be a bird flying with me. On earth, I would like to grow branches together.
Even if it lasts forever, there will always be an end, but this life-and-death feud will never end.
Here are some words that I think are more important. Let me explain to you separately:
Re-delivery message: the imperial concubine is paying attention to saying goodbye and asking him to take a message.
Two hearts know: only Xuanzong and Guifei know.
Immortal Palace: Huaqing Palace in Lishan Mountain was built in the first year of Tianbao (742). According to July, the following six sentences are made up by the author. The so-called longevity hall is not the longevity hall of Huaqing Palace, but the customary name of the bedroom hall of Chang 'an Palace.
Two-winged bird: the legendary bird name. It is said that only one eye and one wing can fly together.
Connecting branches: The trunks of two trees embrace each other. The ancients often used these two things to describe lovers falling in love and never parting.
Hate: regret.
Continuous: continuous.
It may be difficult to understand the meaning only by reading the article, so it is better to understand it in combination with the creative background of the article at that time:
In the first year of Yuanhe in Tang Xianzong (AD 806), Bai Juyi was appointed as the county commandant (now Xi zhouzhi county). One day, my friends Chen Hong and Wang Zhifu and I visited Xianyou Temple near Ant, and talked about Li Longji and Yang Guifei. Wang Zhifu believes that something as outstanding as this will disappear with the passage of time if it is not polished. He encouraged Bai Juyi: "Lotte is deeper than poetry and deeper than love. How about trying to make a song? " So Bai Juyi wrote this long poem. Because the last two sentences of the long poem are "the earth lasts forever, and the sky lasts forever;" One day, both will end, and this endless sadness will last forever. "They called this poem" The Song of Eternal Sorrow ". At the same time, Chen Hong wrote a legendary novel "Song of Eternal Sorrow".
Now that we're here, let's appreciate and comment on Song of Eternal Sorrow:
Song of Eternal Sorrow is a narrative poem with strong lyrical elements. The poet adopted the expressive techniques that China's traditional poems are good at telling stories and portraying characters, and harmoniously combined narrative, scenery description and lyricism, thus forming the characteristic of the poem's lyricism. Poets sometimes inject the thoughts and feelings of the characters into the scenery, and use the refraction of the scenery to contrast the mood of the characters; Sometimes we grasp the distinctive scenery and things around the characters, express their inner feelings through their feelings, and render them layer by layer, appropriately expressing the unspeakable feelings hidden in the hearts of the characters. On his way to the southwest, Emperor Xuanzong of the Tang Dynasty was surrounded by yellow dust, plank roads and high mountains. The sun is dim, the standard is dull, and autumn scenery is desolate. This is a sad autumn scenery to set off the sad thoughts of the characters. In Shu, facing the green mountains and green waters, we still can't forget ourselves. The mountains and water in Shu are beautiful, but in the lonely and sad eyes, the "green" of the mountains and the "green" of the water are also sad. The beauty of nature should be appreciated with a quiet mind, but he didn't, so he increased his inner pain. This is to write sad feelings through beautiful scenery, so that feelings are deeper. The moonlight in the palace and the bell on a rainy night are already very exciting. The poet grasped these unusual but distinctive things and brought people into the realm of sadness and heartbreak. In addition, when they see and smell, they are intertwined, which also shows the sadness and sadness of the characters in language and tone. This is another floor. Still on the road, "everything is spinning" was originally a happy thing, but the old place ended and Yu Yan disappeared, so I couldn't help crying. In the narrative, another layer of painful memories is added. After returning to Chang 'an, "ponds, gardens, palaces, everything is the same as before, Taiye Lake hibiscus, Weiyang Palace willow. But petals are like her face, and willow leaves are like her eyebrows. Whenever he looks at them, what can he do but cry? " . During the day, caused by the environment and scenery, people are associated with the scenery, and the scenery remains the same, but people are gone. I can't help bursting into tears. From the hibiscus flowers in Taiye Pool and the weeping willows in Weiyang Palace, I seem to see the appearance of Yang Guifei, showing the extremely complicated and subtle inner activities of the characters. "Fireflies were flying on the throne, while he was meditating in the twilight. He will extend the wick to its end and still never fall asleep ... bells and drums will slowly ring the long night, and before dawn, the Milky Way in the sky will become clear. " From dusk to dawn, the focus is on the scene where you can't sleep for a long time because of emotional troubles at night. This bitter yearning is like "peaches and plums bloom and the spring breeze blows" and "after the autumn rain, the fallen leaves return to their roots". It is sad to see that the "disciples of Liyuan" and "A Jian Qing E" in those days were all white-haired and their faces were withered, which reminded us of the happy thoughts of the past. From the rambling of Huang Chen to the lush of Shushan, from rainy night in the palace to triumphant return, from day to night, from spring to autumn, we are moved by things everywhere, always thinking of people, and repeatedly rendering the protagonist's hard pursuit and search from all aspects. If you can't find it in real life, you will find it in your dreams. If you can't find it in your dream, go to fairyland. This kind of ups and downs, layer by layer rendering, let the characters' feelings swirl up and reach a climax. It is through such layers of rendering that the poet repeatedly expresses his feelings and goes back and forth, which makes the characters' thoughts and feelings more profound and rich, and the poetry is "delicate in texture" and more artistic.
People have always been controversial about the theme of Bai Juyi's Song of Eternal Sorrow, including the so-called love theory, political theme theory, dual theme theory and so on. The author of this article holds the theory of love. First of all, from the analysis of four aspects of the work, it is affirmed that Bai Juyi did not describe Li Yang's story in a didactic way like Chen Hong's Song of Eternal Sorrow, but took "emotion" as the main theme, so that the hero's emotion moved the reader and made him produce a * * * sound, which achieved great aesthetic success. Based on the author's life experience and social history, this paper also analyzes his uniqueness in dealing with the relationship between historical themes, political themes, humanistic themes and psychological themes from the people, and further explains the aesthetic significance of Yang Guifei's image in the Tang Dynasty.
As soon as Song of Eternal Sorrow came out, its theme has always been the focus of debate among readers. There are also very different views. There are generally three kinds: one is the theme of love. It is a love poem praising Li Yang. And affirm their sincerity and persistence in love; The second is the political theme theory. It is believed that the focus of the poem lies in allegory, exposing the "endless hatred" that "the emperor of China, whose lust may shake the beauty of an empire" will inevitably bring, and condemning the debauchery of the Tang and Ming emperors that led to the Anshi Rebellion, so as to admonish the later monarchs; The third is the dual theme theory. It is believed that it is a mixture of exposing and praising unity, irony and sympathy, which not only shed tears of sympathy, but also blamed on political misconduct and resentment. How, still want to analyze from the work itself.
