Please help me find out the images in Du Fu's Spring Hope and tell me how each image expresses the poet's feelings.

I wrote four images: capital, mountains and rivers, cities and vegetation. Features: the country is broken, and the mountains and rivers remain the same; The city is spring and the vegetation is deep. Formed a dilapidated scene of Chang' an in autumn: the capital fell, and the city was ruined. Although the mountains and rivers are still the same, the grass is everywhere and the trees are gray, which makes people sad.

The first link means: although Jiangshan is still interested, the country has been harassed wantonly; In spring, Japan is full of flowers. Why can't it be a weed in Beijing? Turning your face means: I feel that the situation is turbulent, and I feel tears when I see bloom; It is also shocking to hear birds singing when you are bitter about leaving home. For three months in a row, riots continued. I don't know if my relatives are safe, but my letters from home are the most valuable. The bonfire means that the more I scratch my white hair, the more I hope, and the hair clasp can't be inserted. I don't know how to say worry, but how can I have the word "worry"! Guan Bai refers to white hair and hairpin, which means that adult men in ancient times had to tie their hair, so it was also used. Appreciation: This is an immortal masterpiece written by the poet because he was trapped in Chang 'an occupied by An Shi Rebellion. In the face of flying wars and broken rivers and mountains, the poet can't help but feel worried and deeply moved. This poem is set off by beautiful spring scenery and beautiful things.
