The verbs "shake" and "drip" are particularly magical. The city will not "shake", but "cool wind", water shaking and shadow shaking will give you an illusion, and the city will also shake. The moon does not "drop" dew, but is an "independent tall building". Looking at the bright autumn moon, it seems that dew drops from the moon. "Drip" and "shake" make the whole still picture fly, and let many ordinary scenes such as clouds, water, cities, dew and moon show their emotions together, which makes people think and fascinate. This description not only reflects the strangeness of the romantic poet's imagination, but also fully shows his keen feeling and careful observation of nature, so he can capture the main characteristics of the objective scenery, "in a word".
"Xie Xuanhui explained that' Cheng Jiang Ru Lian' is a long memory." Xie Xuanhui, a famous poet in Southern Qi Dynasty, was once a local official and a Beijing official, and was later framed and put to death. Li Bai worshipped Xie Tiao very much all his life, because Xie Tiao's poetic style was fresh and elegant, his personality was aloof and honest and frank, and his misfortune was similar to Li Bai's. In Li Bai's words, it is called "connecting the past and the present" (see Xie Gongting). When Xie Tiao was driven out of Beijing and left Jinling, he wrote the famous poem "Going to Wangjing Town in the Late Three Mountains", describing the magnificent scenery of Jinling and expressing his worries about his hometown. "Cheng Jiang Ru Lian" is one of the lines of this poem. He compared the clear river to white silk. Li Bai visited the West Building at night and Xie Tiao visited the Three Mountains at night. The situation is equally unfortunate and the mood is equally depressed (Li Bai wrote this poem after being raped and mutilated by power and being excluded from Chang 'an). He will naturally think of the river scenery written by Xie Tiao in those years, and think of Xie Tiao's mood in writing this poem, so he gives a heartfelt admiration: "Xie Xuanhui understands the truth and is a timeless memory." It means: I deeply miss Xie Tiao's ability to sing such a good poem as "Cheng Jiang Ru Lian". There is a sentence in these two sentences, and its subtext is: I am in the same spirit as Xie Tiao, and I can understand his poems; Writing this poem today is the same as Xie Tiao's mood. Who can "explain" and "remember for a long time" This shows that Li Bai's "long memory" of Xie Tiao is a feeling of being in a dark world, lacking a bosom friend and being lonely. This is the meaning of this poem, which is expressed implicitly at the end, echoing the "independence" at the beginning, making people feel how lonely and sad the poet who meditates under the moon is.
