Ascending the Mountain is a seven-metrical poem written by Du Fu, a great poet in the Tang Dynasty, in Kuizhou in the autumn of the second year of Dali (767). The first four sentences describe the scenery, describe the experience of climbing mountains, closely follow the seasonal characteristics of autumn and describe the empty and lonely scenery by the river. The first couplet is a partial close-up, and the couplet is an overall vision. The last four sentences are lyrical, describing the feelings of climbing mountains. Around the author's own life experience, they express the sadness of being poor, old and sick, and living in another country. The neckband hurts their life experience and reveals the meaning of metaphor, symbol and suggestion contained in the first four sentences of landscape writing. Tailian complained again, shutting down with the self-image of depression and disease. The language of this poem is concise, the whole poem is dual, and one or two sentences are still correct, which fully shows that Du Fu's mastery and application of poetic language temperament in his later years has reached the realm of tact.
