Du Mu  Du Mu (; 803–852) was a leading Chinese poet of the late Tang dynasty. His courtesy name was Muzhi (), and sobriquet Fanchuan (). He is best known for his lyrical and romantic quatrains. Regarded as a major poet during a golden age of Chinese poetry, his name is often mentioned together with that of another renowned Late Tang poet, Li Shangyin, as the "Little Li-Du" (), in contrast to the "Great Li-Du": Li Bai and Du Fu. Among his influences were Du Fu, Li Bai, Han Yu and Liu Zongyuan. Du Mu was born in the Tang capital Chang'an (modern Xi'an) into an elite family, the Jingzhao Du clan, whose fortunes were declining. His grandfather was Du You, a minister at the Tang court and the compiler of the Tang Dynasty encyclopedia "Tongdian". He passed the "jinshi" ("Presented Scholar") level of the imperial civil service examination in 828 at the age of 25, and began his career as a bureaucrat holding a series of minor posts, first as an editor of at the Institute for the Advancement of Literature. A few months later, he joined the entourage of Shen Chuanshi (), a surveillance commissioner, first to Hongzhou, then a year later to Xuanzhou. In 833 he was sent to join Niu Sengru in Yangzhou. In Yangzhou he began to mature as a poet. In 835 he was appointed investigating censor and returned to the capital where, possibly concerned about being drawn into a factional dispute involving his friend Li Gan who had opposed Zheng Zhu, he asked to be transferred to Luoyang. This was granted, and he avoided the purge that followed the Sweet Dew Incident which happened later in the year. Du Mu held many official positions in various locales through the years, but he never achieved a high rank, perhaps due to enemies made in a factional dispute at the imperial court in 835. In 837 he returned to Yangzhou to care for his younger brother Du Yi who was sick and had become blind, then went to work in Xuanzhou, taking his brother with him. In 838 he was appointed Rectifier of Omission of the Left and Senior Compiler of the History Office, and he returned to Chang'an. In 840 he was promoted to Vice Director of the Catering Bureau, then transferred to the position of Vice Director of the Board of Review in 841.
