Huanxisha was a poem written by Su Shi, a writer of the Song Dynasty, around 1075. This poem described the author's comfortable mood while washing gauze by the stream as the theme to express his love for nature and his pursuit of freedom. With its fresh and bright language, magnificent artistic expression, and profound thoughts, the Ci became a classic in the history of Chinese literature and was known as "Dongpo's Ci". At the same time, the Huanxi sand became a widely circulated allusion in Chinese culture. It was quoted, interpreted, and adapted many times, becoming an important part of Chinese culture.
