1. According to the content of this poem, we can see that the protagonist is the Cowherd and the Weaver Girl:
The Farewell Altair is the tenth of the "Nineteen Ancient Poems", which reflects the love life with the help of the story of the Cowherd and the Weaver Girl in ancient myths and legends. Petunia and Weaver Girl are the names of two stars. In Nineteen Ancient Poems, this poem "The Far Morning Altar" describes the separation of the couple, the morning glory and the weaver girl. Its era is in the late Eastern Han Dynasty, slightly earlier than that of Cao Pi and Cao Zhi.
Second, according to the appreciation of poetry, we can also see:
Petunia and Weaver Girl are the names of two stars. Altair, or "Hegu II", is in the east of the Milky Way. Vega, also known as "Tiansun", is in the west of the Milky Way, opposite to Petunia. In China, the folk story of Guantian Petunia and Zhinv originated very early. The Book of Songs Xiaoya Dadong has written about Petunia and Weaver Girl, but it is only written as two stars. "The Spring and Autumn Period and Yuan Ming Bao" and "Huai Nan Zi Bo Zhen" began to say that the weaver girl is a goddess. In Cao Pi's Yan Ge Xing, Cao Zhi's Luo Shen Fu and Jiu Yong, Petunia and Zhinv have become husband and wife. Cao Zhi's "Nine Odes" said: "The cow is the husband and the weaver is the woman. The star of the Weaver Maid Petunia is next to the river drums everywhere, and it will take a while on July 7. " This is the clearest record at that time. In Nineteen Ancient Poems, this poem "The Far Morning Altar" describes the separation of the couple, the morning glory and the weaver girl. Its era is in the late Eastern Han Dynasty, slightly earlier than that of Cao Pi and Cao Zhi. Comparing this poem with the works of Cao Shi brothers, we can see that the story of Petunia and Weaver Girl has probably been finalized during the period from the end of the Eastern Han Dynasty to Wei. This poem is about a couple holding a cow and a weaver girl in the sky, but the viewpoint is on the ground, which is to observe the parting pain of their couple with the eyes of a third party. The first two sentences are written from two places, saying that the cow is "distant" and the weaver girl is "bright". Tiao Tiao and Jiao Jiao have different views on each other, so we can't be persistent. The morning glory is also bright, and the weaver girl is also far away. They are all so far away and so bright. However, it is easy to think of a wanderer far away from home with a petunia belonging to a distant genus, while it is easy to think of the beauty of women with a weaver girl belonging to a distant genus. In that case, it seems that they are not interchangeable again. If it is intertextual, it is changed to "the morning glory, the distant river girl", and its interest will be reduced by half. The subtlety of poetic language can be seen here. The reason why the Weaver Girl is called "Hehan Girl" is to make up three syllables, while avoiding using "Vega" in three words. "Altair" has been used in the previous sentence, and "Vega" is used in the next sentence, which is neither rhyming nor monotonous. "Hehan girl" is much more vivid. "Hehan woman" means the woman on the edge of the Milky Way, which is more reminiscent of a real woman and ignores that she is a star. I don't know if the author had such painstaking efforts when writing poems. Anyway, different writing methods have different artistic effects. In short, the arrangement of the ten words "Altair, Jiaojiao River Hannv" can be said to be the most ingenious arrangement and has the most muddy effect.
