On the Function of Wu Diancheng's Killing the Duke and Immortal Couplet

Function expresses wishes and expectations for Wu Diancheng. Let's just say that Wu Diancheng's poem "Remember the words in Shaoling's poems, and know that you can't live up to Gong Meichun" directly quotes Du Fu's poem, which means that plum blossoms will bloom in Gongxian in spring, expressing his best wishes to Wu Diancheng, hoping that he can make a difference in Gongxian and live up to this land. At the same time, through the use of allusions, the cultural connotation and artistic appeal of poetry are enhanced.
