This paper tries to take Du Fu's "Climbing Yueyang Tower" as an example to analyze how Du Fu's depressed and frustrated style is reflected in this poem.

"Depressed and frustrated" is a term put forward by Gao Yun, a literary critic in Ming Dynasty, to describe Du Fu's poetic style, which generally refers to the deep, dignified and melodious characteristics of Du Fu's poems. "Depression" is mainly manifested in emotion, which means that the emotions expressed in poetry are deep and complicated, often containing sadness and anxiety; "frustration" is mainly reflected in rhythm, which refers to the ups and downs of poetry rhythm.

In Du Fu's poem "Climbing Yueyang Tower", the gloomy and frustrated style is vividly reflected:

1. Deep and complicated emotions: The whole poem takes climbing stairs as the trigger point, expressing the poet's deep feelings about the country's destiny and personal experience. The first couplet, "I've heard about Dongting Lake for a long time, and now I'm on this tower", expresses the poet's sigh of vicissitudes. The antithetical couplet "There is Wu in the east and Chu in the south, and you can see the endless drifting of heaven and earth" depicts the magnificent scene of Dongting Lake, while the antithetical couplet "My relatives and friends have no faith, and I am old, weak, sick and lonely" turns to a personal bleak situation, expressing the poet's thoughts for relatives and friends and sadness about wandering life in his later years. "There are wars and mountains on the north side of this wall. How can I not cry at this railing?" Pushing the feelings of worrying about the country and the people to a climax reflects Du Fu's profound feelings of home and country.

2. Rhythm cadence: In phonology, this poem strictly follows the flat rule of seven-character verse, and the flat alternation between sentences and couplets makes it read with clear rhythm and ups and downs. Especially between the mandibular joint and the cervical joint, the magnificent description of the external scene turned to the bitterness of the inner world, which formed a strong emotional contrast and leap, reflecting the characteristics of frustration.

Generally speaking, the poem "Climbing Yueyang Tower" shows Du Fu's gloomy and frustrated poetic style through profound emotional expression and cadence.
