Yu Wenxuzhong (1079~1146) was a patriotic politician and poet in the Southern Song Dynasty. He was originally from Henan and entered Shu in the late Tang Dynasty. A native of Guangdu, Chengdu (now Shuangliu, Chengdu). Due to Qin Hui's informant, the Jin Kingdom discovered that he was an undercover agent of the Southern Song Dynasty. Later, his whole family was brutally murdered by Jin Xizong. Yu Wenxu's poems and essays on Zhonggong, "History of the Jin Dynasty" and "History of the Song Dynasty" all said that he had a collection of essays that was widely circulated in the world. It has been anecdotal to this day. There was no Cai Gong in Dading Dynasty, and Dang Gong (Huaiying) in Mingchang Dynasty." Yu Wenxuzhong's poetry creation can be divided into two periods. There are not many works written in the Song Dynasty that have survived. The poems are relatively ordinary and mainly express personal worries about traveling. When he was imprisoned in Jin Dynasty, his poetry style changed, and he often wrote angry words, such as one of "Three Poems Composed on Jin Day": "I am full of poems and books about ancient and modern times, and it makes me sad to live in exile for many years. I am imprisoned in the army mansion all day long in the south crown, and where are the wild geese in the north?" When I go to Shanglin? I open my mouth to destroy the empty body, and run around with my waist still full of gold. The sharp sword is here now, and the evil hatred is the deepest!" Some other poems, such as "The Angel of Shangwulin", "Spring Day", "Books on Ji You Sui", "Passing Juyongguan", "An Ding Daozhong", etc., some criticize the Jin people for betraying the alliance, or write about feelings of fortress and homesickness, all of which have more content and emotion, and are similar to those about escape and Zen, etc. Si's works are in sharp contrast. Yu Wenxu is not famous for his lyrics, but there are two poems "Yingchun Le" and "Lichun" and "Niannujiao", both of which write about the thoughts of the motherland. Yu Wenxuzhong is as famous as Wu Ji. His collection of poems has not been passed down. Today, more than 50 poems have been preserved, which are included in "Zhongzhou Collection" and "Quanjin Poetry". The lyrics were included in Tang Guizhang's "Quan Jin Yuan Ci". "Song Dynasty Shu Prose Collection" contains twelve short and long articles.
