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