In November of the 14th year of Emperor Xuanzong of the Tang Dynasty (755), An Lushan mobilized troops to rebel against the Tang Dynasty. In June of the following year, the rebels captured Tongguan, Shaanxi Province, and Emperor Xuanzong fled to Sichuan in a hurry. In July, the Crown Prince Hengli was located in Lingwu (now Gansu), named after Tang Suzong. Du Fu inquired and placed his relatives in Duzhou. He took refuge in Su Zongchao alone. He came to the conclusion that the tragedy was captured by the rebels on the way and sent to Chang 'an, Beijing, but he was not imprisoned because of his low rank. In Chang 'an in spring, flowers and birds are singing, and the scenery is charming. It should have been pleasant, but because of the storm all over the city, the writer felt sad, so he saw beautiful flowers, spilled wine and shed sad tears.

The war was separated from my family, and the news was blocked, but the war burned to Chang' an, Beijing, and it was endless. I was trapped in Chang 'an, captured by rebels, and even lost contact with my family. At this time, I miss my family in the discrete variables. After three months of war, a letter from home is worth a ton of gold, which only expresses an anxious hope and impatience. At this time, a letter from home is really worth more than two thousand gold! This sentence has a simple meaning, but it has aroused everyone's consensus and understanding, and has become a famous saying that has been sung through the ages. Finally, it ends with "lost hairpin" to see the pain of leaving the chaos at that time. I keep bowing my head, but my hair is getting shorter and shorter as it grows older, and it is getting rarer and rarer. I can't even catch my hair.

The whole poem is very frustrating, and the endless feelings between words are obvious. Brother Shen, extremely charming. Huang Chao Uprising, the fall of the Central Plains, and the fall of Beijing, the life and death of the Chinese nation, the people are in dire straits. Du Fu suffered a lot in this chaos. At first, he was captured by the rebels and imprisoned in Chang 'an, Beijing. Later, he fled to Tang Suzong to take refuge. He wanted to serve the motherland, but he was ashamed of his loyalty and was exiled. During this period, Du Fu ran around and wandered around, deeply impressed by the misfortune and pain brought by the war.

During this period, he also wrote famous works such as Three Officials and Three Partings, with distinct themes, which truly and profoundly expressed that era, better than the simple records of historians. There are many reasons for the "Huang Chao Uprising", including differences in economic development and class struggle. In the last years of Emperor Xuanzong of the Tang Dynasty, he lived a dissolute daily life all day, and the Yang Yuhuan family was the envy of the world. The corruption of the exploiting class has increased people's pressure and promoted the continuous aggravation of social problems. The treacherous men also strengthened the differences in the internal structure of the exploiting classes, and the power struggle between Yang and An Lushan became the fuse of the Huang Chao Uprising.
