Lu Xun said that "tragedy is to smash beautiful things for people to see", and Li Yu's ci has a strong tragic beauty. His sadness comes from his unique life experience, from the monarch of the Southern Tang Dynasty to the prisoner. This huge ups and downs of life will inevitably lead to extremely strong ideological changes. From the early court life and the love between men and women, it evolved into the pain of national subjugation. At that time, its tragic color was unparalleled.

Many of his excellent works, such as Yu Meiren, Langtaosha, Welcome to the South of the Yangtze River, Midnight Song and childlessness, were written in the background of leaving home. Looking at the distance, the feeling of returning to the dream, the feeling of tears in the spring rain, and the feeling of caring by the riverside deeply shocked the readers' hearts.
