Du Fu, a social poet, takes the rise and fall of politics, social unrest, war corvee, hunger and poverty, and the disparity between the rich and the poor as his themes, which are extensive in content, rich in times and realistic. Du Fu's poems are good at describing the historical situation at that time and reflecting the present situation of the Tang Dynasty from prosperity to decline, so they are called "the history of poetry". From the Anshi Rebellion to entering Shu, Du Fu experienced great turmoil and wrote a lot of realistic works. In his representative works, many realistic works, such as Two Ways, reflect the luxury of the upper class.
