What does it mean to say that "a relationship needs a long time, and you can't get along day and night"?

"If love lasts for a long time, it will be there sooner or later" means that as long as you love each other forever, why not leave early and leave late?

Qiao Yun, the Fairy of Queqiao, written by Qin Guan, a poet in the Song Dynasty. This is the preface of Tanabata, which eulogizes sincere, delicate, pure and loyal love through the fairy tale of Cowherd and Weaver Girl.

Original text:

The thin clouds in the sky are changing, the meteors in the sky convey the sadness of acacia, and the endless galaxy I quietly crossed tonight. On the seventh day of autumn dew and autumn, it is time to meet, mostly those who are together in the world, but the appearance of husband and wife.

Common complaint against acacia, tender feelings like water, meet each other as if it were a dream, when it is hard to see the bridge. As long as two people love us to the end, why covet my Heron?

Vernacular translation:

Thin clouds are changing in the sky, meteors are conveying the sadness of acacia in the sky, and I quietly crossed the distant and boundless galaxy tonight. Tanabata meeting in the autumn wind and white dew is better than those couples who are together in the world.

Tender feelings are like flowing water, and the day of reunion is like a dream. I can't bear to see Queqiao Road when I leave. As long as two people love each other till death do us part, why do you want to be very much in love?

The first part of this word is about the gathering of cowherd and weaver girl, and the second part is about their differences. Sorrow and music are intertwined in the whole poem, which melts lyricism and discussion into one furnace, into the whole world, and combines beautiful images with deep affection to eulogize the ups and downs of beautiful love. This first word has profound feelings, lofty thoughts, beautiful language, free and smooth discussion, and is easy to understand, but it is elegant and memorable, especially the last two sentences, which sublimate the ideological realm of the word to a brand-new height and become an eternal sentence.

Analysis:

Through the story of Cowherd and Weaver Girl, the joys and sorrows of the world are expressed in a superhuman way, which has existed since ancient times, such as Nineteen Ancient Poems, Cowherd Star, Cao Pi's trip, Li Shangyin's Tanabata and so on. In Song Dynasty, Ouyang Xiu, Zhang Xian, Liu Yong, Su Shi and others also sang this theme. Although they choose different words and make different sentences, they all follow the traditional theme of "happiness is short" and have a sad and sad style. In contrast, the word Qin Guan is unique and verve.
