Yang Shen was a renowned litterateur in the Ming Dynasty. During his exile in Yunnan, he crossed the Jinsha River and returned to Chengdu via Liangshan. The paper begins with an analysis of Yang''s poem "Lodging by the Jinsha River" and compares the distinct features of the Jialing River, Minjiang River, and Jinsha River portrayed in his poems and their respective literary implications rich in Bashu characteristics. When portraying the Jialing River, Yang frequently cites the "Daozhou Dream", a historical allusion centering on realizing one''s aspirations, while the Jinsha River evokes his meditations on the history of the Three Kingdoms. Portrayal of Bashu rivers reveals Yang''s political disillusionment and the migratory trajectory of his literary career, which provides a vantage point to explore Yang''s intellectual and artistic evolution.
