Zhu Dunru's Qiaoge is,in a sense,his autobiography.The three periods of his life experience and the changes in his thoughts and emotions run through it,thus forming a triple aspect of the aesthetic realm accordingly.From the perspective of aesthetics as a whole,the evolution of Zhu's works is explored,i.e.the beauty of freedom in his youthful works,the beauty of tragedy in his middle-aged works,and the beauty of idleness in his later works,so as to further excavate the rich aesthetic connotations of Qiaoge,and to highlight its grand aesthetic colors.The three periods of Zhu's life and three states of his mind are linked with the threefold aesthetic realm,making the poetic beauty interrelated with the aestheticised human existence.
