Lu You (or Lu Yu, 1125–1209) was a prominent poet of China's Southern Song Dynasty.
Lu You wrote about eleven thousand poems, in both the shi (詩) and ci (詞) forms, plus a number of prose works. In his poetry he continues to articulate the beliefs which cost him his official career, calling for reconquest of the north. Watson identifies these works as part of the legacy of Du Fu (杜甫). Watson compares a second body of work, poems on country life and growing old, to those of Bai Juyi (白居易) and Tao Qian (陶潛).
His style can be divided into three periods.
The first Period of Lu You’s works is from his teenage years to age 46. This period, although the longest, contains the fewest of his works, about two hundred poems, because he himself destroyed his early works.
Second Period runs from age 46 to 54, including more than 2400 shi and ci. During this period, Lu You joined the military and was affected by that experience.
The third Period runs from the time Lu You retired to his home town until his death. He did not have time to edit his work, and 6500 poems survive from this period. His work in this period includes peaceful pastoral images as well as desolation and bleakness.
Though his style changed throughout his life, his work is always full of patriotism. This is the most important feature of his poetry, and the major reason they have been valued for almost a thousand years.
