Writing background: This poem is the work of Du Fu, a great poet in the Tang Dynasty. This poem was written in 76 1 year, that is, in August of the second year of Su Zong Shang Yuan in the Tang Dynasty. In the spring of 760 AD, Du Fu sought relatives and friends everywhere because of poverty, and finally built a decent hut in a place called Huanhuaxibian in Chengdu today, and finally got a place to live.
In 759, the thatched cottage was destroyed by the autumn wind, the Anshi rebellion was undecided, and there was great hunger in the customs. It is because the abandonment of the official led the whole family to the Western Expedition, experienced hardships and witnessed the sufferings of the people. He wrote about "three officials" (Shi Haoguan, Tongguan official and Xin 'an official) and "three farewells" (newly married and retired old people).
