present-day Kaifeng. In a later poem, Li wrote about the shame and regret he had on the day he was taken away from Jinling (as translated by Hsiung Ting): Devotion to the arts Although, Li Yu indeed was a great exponent and developer of the cí poetry form, which sometimes or often seems to characterize poetry of the Song Dynasty, there is also some difficulty in categorizing him as a Song poet: the Southern Tang state is more of a continuation of Tang than a precursor on the Song side of the divide of the history of the Tang-Song transition, also known as the Five Dynasties and Ten Kingdoms period. Li Yu represents both a continuation of the Tang poetry tradition, as well as representing the cí poetic style which is so especially associated with the poetry of Song. Li Houzhu devoted much of his time to pleasure-making and literature, and this is reflected in his early poems. A second phase of Li's cí poems seems to have been the development of an even sadder style after the death of his wife, in 964. His best-known, and saddest, poems were composed during the years of his captivity, after he formally abdicated his reign to the Song, in 975. He was created the Marquess of Wei Ming (; , "Marquess of Disobeyed Edicts"), a token title only: actually, he was a prisoner, though with the outward accoutrements of a prince. Li's works from this period dwell on his regret for the lost kingdom and the pleasures it had brought him. He developed the ci by broadening its scope from love to history and philosophy, particularly in his later works. He also introduced the two stanza form, and made great use of contrasts between longer lines of nine characters and shorter ones of three and five. Only 45 of his ci poems survive, thirty of which have been verified to be his authentic works, the other of which are possibly composed by other writers: also, seventeen shi style poems remain to his credit. His story remains very popular in many Cantonese operas. Death He was poisoned by the Song emperor Taizong in 978, after he had written a poem that, in a veiled manner, lamented the destruction of his empire and the rape of his second wife Empress Zhou the Younger by the Song emperor. After his death, he was posthumously created
