Deciduous trees: fallen leaves, deciduous trees.
"The endless falling trees rustle", falling trees, expresses the typical characteristics of Kuizhou's autumn.
The real beauty of this sentence lies in the three words "boundless", "endless" and "xiaoxiao". The poet looked up at the boundless swaying wooden leaves and looked down at the endlessly flowing and rolling river. While describing the scene, he deeply expressed his feelings. "Boundless" and "Endless" make "Xiao Xiao" and "Rolling" more visual, which not only reminds people of the sound of falling wood and the turbulent shape of the Yangtze River, but also conveys the feeling of time passing by and ambitions elusive.
"Deng Gao" is a seven-rhyme poem written by Du Fu, a great poet of the Tang Dynasty, in the autumn of the second year of Dali (767) in Kuizhou.
The first four sentences describe the scenery, recount the experiences of climbing high, closely follow the seasonal characteristics of autumn, and depict the empty and lonely scenery of the river. The first couplet is a partial close-up view, and the chin couplet is an overall distant view. The last four sentences are lyrical, describing the feelings of climbing high. They revolve around the author's own life experience and express the sadness of being poor, old and sick, and living in a foreign country. The neck couplet reveals one's own life experience, revealing the metaphorical, symbolic, and suggestive meanings contained in the description of the scene in the first four sentences; the last couplet makes another statement and ends with the self-image of decline and illness. The language of this poem is concise, with parallelism throughout, and even one or two sentences that are paired within a sentence, which fully demonstrates that Du Fu's grasp of the rhythm and rhythm of poetic language has reached a state of perfection in his later years.
