In the eyes of the emotional and reserved ancients, the Milky Way flowing in the sky became the object of their sleepless nights. The poem "Song of Everlasting Sorrow" by Bai Juyi, a poet of the Tang Dynasty, said, "The bells and drums are late and the night is long, and the stars are about to dawn." This is every night that Emperor Xuanzong of the Tang Dynasty experienced. Li Shangyin, another poet of the Tang Dynasty, wrote in his poem "Chang'e": The candle shadow on the mica screen is deep, and the dawn stars are gradually sinking in the long river. Chang'e should regret stealing the elixir, and her heart will be filled with blue sea and blue sky every night. In early autumn, the long river gradually falls, and another night passes. The lonely and desolate mood in the poem moves every reader. When poets write about the Milky Way, they always describe it together with Altair and Vega. Du Mu, a poet of the Tang Dynasty, wrote in "Autumn Evening": "The cold autumn light of silver candles paints the screen, and the small light fan flutters at the flowing fireflies. The sky is as cold as water at night, and I sit and watch the Altair and Vega." The poetic scene is similar to Li Shangyin's "Chang'e", but One is written about people in heaven, and the other is written about people on earth. Liu Yuxi, a poet of the Tang Dynasty, wrote in "Lang Tao Sha": "The Yellow River has thousands of miles of sand, and the waves are blown by the wind from the end of the world. Now we go straight up to the Milky Way, and we go to the home of the Morning Glory and the Weaver Girl." Different from the above two poems, it is unique and heroic. Romantic color. The myth and legend of the Morning Bull and the Weaver Girl has a long history in our country, and it has also gone through a long development process. The famous "Nineteen Ancient Poems" inherits and develops the story elements in "The Book of Songs": the far-off Altair star and the Han girl on the bright river. The slender hands are used to make tricks. I can't make up my mind all day long, and my tears are like rain. The river is clear and shallow. How far has it gone? There is a room full of water, and the pulse is speechless. Altair is far away and Vega is bright. They look at each other all day long but cannot get together. "There is a lot of water in the water, and the pulse is speechless." The poem is implicit and meaningful, with a long aftertaste. I don’t know since when, in folklore, there has been a plot of the Cowherd and the Weaver Girl getting together every year on the seventh day of the seventh lunar month. In the hands of later poets, this rather tragic story gained more sympathy. Qin Guan, a poet from the Song Dynasty, wrote in "Magpie Bridge Immortal": "The thin clouds make tricks, the flying stars spread hatred, and the distance between silver and Han is dark. As soon as the golden wind and jade dew meet, they will defeat countless people in the world. Tenderness is like water, good times are like dreams, and we can't bear to care about them. Returning from the Magpie Bridge. If love lasts for a long time, how can it last forever?" This poem has become the highest praise of the Cowherd and the Weaver Girl's steadfast love and has been passed down through the ages.
