What emotions are expressed in Du Fu's three poems?

"Looking at Yue" is magnificent! ? Out of Qilu, green peaks can still be seen. The magical nature brings together thousands of beautiful mountains in the south and the separation between morning and dusk in the north. Layers of white clouds, cleaning the gully on the chest; The flat bird flew into the eye socket. Try to climb to the top of the mountain: it dwarfs all the peaks under our feet. By depicting the majestic atmosphere of Mount Tai, this poem enthusiastically praised the majestic momentum and magical and beautiful scenery of Mount Tai, expressed the poet's ambition to climb to the top, expressed his great ambition in his early years, and showed an enterprising and positive attitude towards life! The hope of spring Although the country is divided, the mountains and rivers last forever, and all the plants are in spring. Sad state, can not help but burst into tears, amazing birds, leaving sorrow and hate. The war lasted for more than half a year, and letters from home were rare, with a hundred thousand gold. Twisting with melancholy, scratching my head and thinking, the more I scratch my white hair, I can hardly insert a hairpin. This poem is full of lamentations about the failure of Spring City. Expressing homesickness is full of sadness. Reflect the poet's feelings of worrying about the country and homesickness. Li Shihao was cast in Shihao Village at dusk, and officials arrested people at night. The old man climbed over the wall and left, while the old woman went out to watch. Why are officials angry? Why do women cry? Before listening to his wife's speech: three men are guarding Yecheng. One man attached a book, and two men died. Those who drag out an ignoble existence are dead! There is no one in the room, only a baby and a grandson. And grandma didn't go, and there was no skirt in and out. Although the old woman is physically weak, please come back at night and be anxious to prepare for cooking in the morning. The night is long and silent, like crying and choking. Dawn will rise into the future, leaving the old man alone. It shows the author's exposure to the cruelty of the rulers, his deep sympathy for the suffering people in the Anshi Rebellion, and his lofty feelings of worrying about the country and the people.
