Spring Hope is the sentence that sets the emotional tone of the whole text.

I am moved to tears by the flowers, and the birds are frightened by the hatred.

Explanation of the writing characteristics of the poem:

The country is broken, the mountains and rivers are there, and the city is in spring with deep vegetation: The first couplet uses line drawing techniques to describe what Chunwang sees - the country's capital has fallen, and the city is dilapidated. The mountains and rivers remain the same, but they are overgrown with weeds. This couplet not only points out the writing background, but also blends emotions into the scenery, setting the emotional tone of the whole poem.

I feel the flowers splashing with tears, and I hate the birds that are leaving and are startled:

The chin couplet writes about the feelings at the sight, highlighting the crisis of the current situation and the poet's deep sadness. "Feeling the time" refers to worries about state affairs, while "hateful farewell" refers to missing family members.

The war has been going on for three months, and letters from home are worth tens of thousands of dollars:

The neck couplet expresses the poet's anxiety in waiting for news about his family during the continuous war, and shows the poet's deep longing for his relatives. "Lian March" describes the long period of war. "Worth ten thousand gold" uses an exaggerated rhetorical technique to express the preciousness and rareness of family letters. It truly expresses the feelings of people in the war who miss their separated relatives and long for news about their relatives.

The hairpin on the white head is shorter, and the hairpin is too much for lust:

The last couplet uses the details of "the hairpin is too much" to describe the changes in the hair, showing the poet's extremely sad and haggard condition. , implicitly expresses the poet's thoughts and feelings of worrying about the country and the times, missing his family and feeling sad for himself. "White head" is caused by sorrow, "scratching" is an action to relieve sorrow, and "shorter" shows the degree of sorrow. In addition to the pain of ruined country and family, separation and chaos, there is also a sigh of aging, which adds a layer of sadness.

The overall writing characteristics of poetry:

(1) Embodying emotions in scenery and blending scenes. The first couplet writes that the capital was occupied by rebels. The city was dilapidated, overgrown with weeds, and a desolate scene. This is true in the prosperous capital city, let alone other places. From this we can see the pain caused by the Anshi Rebellion to the people.

In the couplet, the flowers and birds are meant to entertain people, but because they were so sentimental and hated to say goodbye, the poet shed tears when he saw them. The poet clearly describes the scenery and expresses his emotions, embodying infinite sadness in the scenery.

(2) The artistic conception is profound and the charm is endless. The sorrow and indignation of the times, the deep affection of flesh and blood, are stagnated in the chest, and the poet is unwilling to express them directly. Facing the broken mountains and rivers and the deserted city walls, the poet was filled with grief. The bright spring scenery, the chirping of birds and the fragrance of flowers only added to his sadness.

Flowers and birds are meant to entertain people, but instead they make people "cry" and "scare". There is a strong contrast in semantics (the eternity of nature and the rapid changes in society form a sharp contrast), and the tone of the poems The reversal of the situation makes the poet's concern for his country and his family reflected artistically. The "war fire" and "letter from home" in the neck couplet are the content of "feeling the time" and the reason for "hate to say goodbye", adding another layer of poetry.

The last typical detail of "Incomparable Hairpin" is implicit and endless, making people feel that the poet has closely integrated his own destiny with the destiny of the country, and his concern for the country and himself is sincere and touching. If you carefully appreciate the deep artistic conception of the whole poem, you can get a glimpse of Du Fu's melancholy artistic style.
