Du Mu (803- 852) was born in Fanchuan, Mu Zhi, Han nationality, Jingzhao Wannian (now Xi, Shaanxi). Du Mu was an outstanding poet and essayist in Tang Dynasty, the grandson of Du You, the prime minister, and the son of Du You. Tang Wenzong Daiwa was a 26-year-old scholar in the second year and was awarded the post of Hong Wen Pavilion. Later, he went to Jiangxi to inspect the ambassador's tent, and then turned to Huainan to inspect the ambassador's tent. He was the editor of the National History Museum, the food department, Bibi department and Si Xun, and the secretariat of Huangzhou, Chizhou and Zhou Mu.
Because he lived in South Fan Chuan Villa in Chang 'an in his later years, he was later called "Du Fanchuan" and wrote "Collected Works of Fan Chuan". Du Mu's poems are famous for their seven-character quatrains, and the main content is to chant history and express emotion. His poems are handsome and natural, and cut into secular things. He achieved great success in the late Tang Dynasty. Du Mu is called "Xiao Du" to distinguish it from Du Fu and "Da Du". Also known as "Little Du Li" with Li Shangyin.
Li Shangyin (about 8 13-858), a native of western Henan, Fan Nansheng, a native of Xingyang, Zhengzhou (now Xingyang, Zhengzhou, Henan), was a famous poet in the late Tang Dynasty, and was called "Xiao" together with Du Mu.
Li Shangyin was one of the few poets who deliberately pursued the beauty of poetry in the late Tang Dynasty and even the whole Tang Dynasty. He is good at poetry writing, and parallel prose has high literary value. His poems are novel in conception and beautiful in style, especially some love poems and untitled poems are touching, beautiful and popular. However, some poems (represented by Jinse) are obscure and inseparable, and there is a saying that "poets always love Quincy and hate that no one writes about Jian Zheng".
In the second year of Tang Wenzong (837), Li Shangyin became the first scholar, and served as secretary of the provincial school, bookkeeper of the school and commander of Hongnong. Because he was involved in the political whirlpool of "the dispute between Niu and Li", he was excluded and frustrated all his life. In the last years of Emperor Xuanzong of the Tang Dynasty (about 858), Li Shangyin died of illness in Zhengzhou and was buried in Xingyang, his hometown. It is also said that he was buried in Yongdian, Huaizhou (now Wangzhuang Town, Qinyang Mountain) at the foot of Qinghua Beishan, whose ancestral home is Dongyuan.
