Thinking about the moon, such as Xie Zhuang's "Moon Fu": "There is a bright moon in a thousand miles." Zhang Jiuling: "I miss you like a full moon, and the brightness decreases every night."
"The moon is at sea now, and the horizon is at this time." "Looking up, I found it was moonlight, sinking again, and I suddenly thought of home." (Tang Libai's "Silent Night Thinking")—
Looking at the moon and homesick, I am extremely sad. The moon in the poem is no longer a purely objective image, but an image full of poet's feelings.
Du Fu's "Remembering Brothers on a Moonlit Night": "He knows that the dew will frost tonight, and the moonlight at home will be bright! "Dew is always white, but tonight is whiter, because it feels like tonight; The moon is unknown everywhere, and my hometown is brighter because I miss my brother and my hometown. The poet takes fantasy as reality to highlight his nostalgia for his hometown. In the Tang Dynasty, Wang Jian wrote "Looking at Du Langzhong at Fifteen Nights": "Tonight, the moon is full, and I don't know whose house Qiu Si will fall." The poem points out the universal human feelings of this full moon night with euphemistic questions, and implicitly shows the poet's deep yearning for his hometown friends. In addition, there are poems such as Zhang Jiuling's "The passage of time makes the moon clear, and now the horizon is * * *" (looking at the moon and thinking far away) and Wang Changling's "I want to invite Wujiang not to come here, see you in my dream" (drinking at night in Cao Zhai, Li Chang) in the Tang Dynasty, all of which are basically the same feelings.
