Li Yu's ci poetry can be divided into two periods, one before and the other after the eighth year of Song Taizu Kaibao (9 7 5). In the previous period, Li Yu's extraordinary talent and superb skills have been shown, but the subject matter is narrow, which mainly reflects the palace life and the love between men and women, such as Spring in the Jade House, Snow in the Evening Makeup, Sue, etc., and there are also works that describe parting lovesickness, such as Qing Ping Le and A Half-Spring in Bielai, etc. The scenery is lyrical and healthier to read. In the later period, Li Yu became a prisoner from an emperor. The humiliating life, the deep pain of national subjugation, and the recollection of the past, "I only care about Lacrimosa" (Silent Record by Wang Yi in Song Dynasty), the achievements of its ci greatly exceeded the previous period. Forty Years of Home Country, a broken soldier, reflects the turning point of his life experience and ci style. Youmei's When is the Spring Flower and Autumn Moon, Sand Waves, Rain Outside the Curtain, Crying at Night and Going to the West Building without Words are his later representative works, which mainly describe.
Wang Guowei's evaluation of Li Yu in Shi Shuo Xin Yu: The words arrived in Li Houzhu, but their horizons began to widen and their feelings began to deepen, so they became the words of a musician and a scholar-bureaucrat. Zhou Jiecun was placed under Zhu, which can be described as reversing black and white; A poet is a man who never loses his childlike innocence. So he was born in the palace and grew up in the hands of women, which is the shortcoming of the late master as a gentleman, that is, the strength of the poet; Subjective poets do not need to read more about the world. The shallower they look at the world, the truer their temperament. So is Li Houzhu; Nietzsche said that all words, I love to write in blood, and the words of the late master are really written in blood.
