The history of poetry refers to Du Fu's coming and going in the face of blood-stained land, so Du Fu's poems are depressed and frustrated. People describe his style as depressed and frustrated, from which we can understand the tragic scene at that time, so his poems are called "the history of poetry".
Du Fu (7 12-770) was born in Gongxian County (now Gongyi, Henan Province). Du Fu's great-grandfather (Du Fu's father) moved from Xiangyang (now Hubei) to Gongxian (now Gongyi, Henan). He was a great realistic poet in the prosperous Tang Dynasty. He is concerned about the country and the people and has a noble personality.
