These two poems also have something in common: expectation of reality, that is, some dissatisfaction with reality.
From the ground to the sky, heaven "associates" a mythical world. In this mythical world, the fair is beautiful, the goods are rare in the world, cowherd and weaver girl can meet at any time, and they can wander around with lanterns, which is simply a paradise. But this paradise is only in the sky, and it is impossible for the world to see it. This is a euphemistic and tortuous criticism of human suffering and misfortune, and it is also "a warm yearning for bright happiness and an expectation for an ideal society, which shows the poet's innocent mind and character in the predicament." Therefore, "Heaven" is a beautiful serenade with a quiet tone. ..... "This is an imaginary picture of a peaceful and clean world." (See Baidu in brackets)
The "star" is basically on the ground, but it compares the lights on the ground to the stars in the sky, and compares the river that reflects the lights to the milky way. It can be said that it is actually wandering on the ground. It expresses frustration and helplessness and dissatisfaction with living conditions. We can clearly know from the following sentences: "Leaves are shivering in the wind", "Homeless meteors are walking" and "The lights in the mountain city are on all night, even if the wind is tight and the clouds are thick this winter night." "The heart trembled with the leaves; Aren't we also constellations on the ground-I'm a weaver girl and you're a morning glory ... "
Generally speaking, what does light mean? Go home! What does home symbolize? Warm and peaceful. However, although the lights here are "as bright as day" and "even if the wind is tight and the clouds are thick this winter night, the lights will not go out all night", the lights have not broken through the clouds to calm the cold wind and warm the winter night. At the beginning of the poem, it says: "Leaves are shivering in the wind", and later it says that there are "homeless meteors walking". For the "homeless meteor", light and "excitement are theirs, and I have nothing" (Zhu Ziqing's words); For homeless meteors, the Milky Way made up of beacon lights is not home at all. Orion, Fairy Queen, Mars and Venus are neither their neighbors nor their own kind. We can't find the same kind of comfort from them, let alone look forward to the warmth of home, although "aren't we also constellations on the ground?" "Weaver Girl" and "Morning Glory" are said to be unable to meet each other because they can't cross the Milky Way. In the "market in the sky", they can not only ride cows, but also walk with lanterns. Although the light of lanterns can't compare with Orion, Fairy Queen, Mars and Venus, or even the "Milky Way" composed of river lanterns, because the Cowherd and the Weaver Girl can be together, and they have a home, which is warm and peaceful.
What about in Star? Although the Cowherd and the Weaver Girl in the stars are also "constellations", they are only "constellations on the ground". Is there a difference between the Cowherd and the Weaver Girl on the ground and the Cowherd and the Weaver Girl on the market in the sky? Yes, because they are "homeless meteors". Because they are homeless, can't get together, can't be together, can't help each other, help each other and warm each other, so their hearts have to "tremble with the leaves" in the "winter night" with tight wind and thick clouds.
