Appreciation of Poems in Justice by Jian Wulang?

This poem was written in 767 AD (the second year of Tang Daizong Dali) in Kuizhou (now Fengjie, Chongqing), when Du Fu was 56 years old. Jane is a letter, and so is this poem. Wu Lang, namely Wu Nanqing, is a "judicial officer" from Zhongzhou (the military staff officer of the state government), a junior in-law of Du Fu, who lives in Kuizhou temporarily and has a good relationship with Du Fu. Du Fu has two houses in Kuizhou, one is Xiqin Caotang near the urban area, and the other is a hut in Dongtun Farm.

He usually lives in Xiqin Caotang. It was autumn, and Du Fu was in charge of 100 hectares of commons. In order to perform his duties better, Du Fu moved to Dongtun, which is more than ten miles east of Baidicheng. After moving, I lent the Qingxi Cottage to Wu Lang (there are four poems about moving from Jingxi Fei Jing to Dongtun Cottage). Autumn note: "This chapter was also written for Wu Lang's residence. From Ge, send a ride to meet each other, and see the love of both sides. I used to have a rest, but now I stop partying and stay in my hometown. Five, six, sparse and clear scenery. Seven or eight, relocation and burial. " The whole poem describes things before and after Wu Lang's arrival.
