Abstract: Poems of social exchange represent the poetic articulation of poets’ behaviors, thoughts, and mentalities in social interactions LU You arrived in Kuizhou (current Fengjie County in the city of Chongqing) at the end of the sixth year of the reign of Qiandao (1170) and left Sichuan Province for his hometown in the east China in the late spring of the fifth year of the reign of Chunxi (1178). In these eight years, completing a significant official journey to Sichuan in his life, he also composed a large number of poems of social exchange. In these poems, LU, portraying himself as a the lyrical speaker, revealed the complex and ever-changing living conditions and emotional states he experienced during his official tenure in Sichuan. By delving into the social elements embedded in his poems of social exchange composed in Sichuan, this study examines his living circumstances and mental transformations in the Bashu region (currently including Sichuan Province and the city of Chongqing). It also presents a glimpse into the tragic life of this great patriotic poet of the Southern Song Dynasty (1127-1279).
