Li Yu is proficient in calligraphy, painting, melody and poetry, especially in ci. Li Yu's ci has inherited the tradition of Hua Jian poets such as Wen and Wei Zhuang since the late Tang Dynasty, and has been influenced by Li and others. Its language is lively, vivid, sincere and distinctive. After the national subjugation, his ci has a wide range of themes and profound meanings, which is unique among the five pronouns in the late Tang Dynasty and has a far-reaching influence on the later ci circles.
