Du Fu's Confucianism is expressed as "benevolence", "noble people" and "benevolent government". In his poems, he expressed concern for the country and the people, exposed the cruel and dark social reality, and hoped that the feudal rulers would implement Benevolent governance realizes the social ideal of prosperity for the country and peace for the people. His poetry is permeated with patriotic sincerity. When the country is in crisis, he will cry with heartache when looking at the flowers and birds of spring. For example, "Spring Hope": "The country is broken by mountains and rivers, and the city is full of spring vegetation. I feel the flowers splashing with tears, and hate the other birds. I am frightened. The war continues for three months, letters from home are worth tens of thousands of gold, and the white hair is shorter than the hairpin." Once the chaos is settled and the news comes, he will burst into tears with joy. For example, "I heard that the army was taking over Henan and Hebei": "It was suddenly heard outside the sword that Jibei was being taken over. When I first heard about it, my clothes were filled with tears. But I saw where my wife was worried. She was filled with poems and books and was wild with joy. When singing during the day, you must indulge in alcohol. Youth is a good companion for returning home. ". Du Fu cared about the fate of the country all his life: "I have always worried about the country and shed tears, and shed my clothes and scarves when I am lonely." From his early ambitions: "To the emperors Yao and Shun, and to make customs pure"; until his death, he was still thinking about: "The blood of the battle still flows, and the sound of the army continues to this day." No matter in good times or bad times, Du Fu's heart for boxing is always so persistent. Du Fu not only never forgets his kingdom at all times, but what is even more touching is that he regards this feeling as a part of his life. The opening chapter of "Five Hundred Words of Empathy from Beijing to Fengxian County" describes the feelings of loyalty to the emperor and patriotism. At that time, Du Fu had two paths in front of him. One was to retreat to the countryside and live a romantic life of "sending the sun and the moon with ease"; Become an official and get involved in complicated officialdom battles. The choice aroused Du Fu's inner agitation. Finally, Du Fu expressed his thoughts: "Today's corridors and temples are not in short supply when it comes to building buildings. Sunflowers and catkins face the sun, and their physical properties are hard to snatch away!" Loyalty to the emperor and patriotism have become the poet's nature. Du Fu's loyalty to the emperor and patriotism is not the "foolish loyalty" advocated by later Confucianists: "If the emperor wants his ministers to die, the ministers have to die". His loyalty to the emperor was based on patriotism and love for the people. On the one hand, he had great illusions about the emperor and hoped that through the emperor's "order to reduce levies and taxes", "everyone would have a barrier"; on the other hand, Du Fu dared to criticize and satirize The emperor, and his "loyalty to the emperor" was mainly reflected in his criticism and satire of the emperor. He also wrote poems such as "Tang Yao is really a saint, how can the old man know it?", "The emperor is so kind, and the people are lonely!" and other poems, which are directly satirical. The supreme ruler of the feudal dynasty. "The people" are the "foundation of the country", and Du Fu's patriotism is different from the general's devotion to his country on the battlefield, and from Qu Yuan's risking his life to persuade. His patriotism is rooted in the "people-oriented" thinking. No poet has so many images of the people in his poems. The old woman's family in "The Official" makes people feel sad and sad; the life and death of the newlyweds in "Farewell" make people sympathize; the old man in his sixties bid farewell to his old wife and resolutely goes to the battlefield in "Farewell". Which poet has such a clear image of these lifelike, flesh-and-blood working people, which makes readers feel compassionate. These unfortunate people in the midst of war showed a high degree of patriotism in actively participating in the war of resistance, regaining lost lands, rebuilding their homes, and saving the Li and Tang dynasties. The poet felt the suffering of the people and used poetry to truly record this period of history, which more reflected the poet's noble sentiments of caring about the country and the people. Du Fu's early poems contained many poems that denounced the arrogance and extravagance of the rulers and sympathized with the sufferings of the people. For example, "The flying eagles at the Yellow Gate are immovable, and the royal chefs are constantly sending eight delicacies" which describes the Yang sisters' prominent status and prosperous banquets ("Beauty's Journey"). "The wine and meat in the rich families stink, and there are frozen bones on the road" ("Five Hundred Words from Beijing to Fengxian County") lashes out at the rulers and is full of sympathy for the common people. It objectively reflects the social reality of the great disparity between the rich and the poor. . After the Anshi Rebellion, Du Fu became a barbarian and lived in various places, witnessing with his own eyes the suffering caused by the war to the people. The works of this period are mostly excellent and are the main body of Du Shi's soul.
