Known as the king of ci of the Five Dynasties,Li Yu,paid special attention to the depiction and portrayal of sound in his ci poetry.The unique charm of Li Yu's works lies in his technique of integrating sound into the ci,writing about indulgence and pleasure,escaping reality;mourning the spring and autumn,expressing personal feelings;the sorrow of a city's fall,and the resentment of losing a nation.By utilizing different types of sound in his writing,supplemented by the creative method of conveying cool emotions through a cool tone,and combining movement with stillness,he crafted a distinctive sonic ambiance in his ci poetry.This not only laid the groundwork for his emotional expression but also enhanced the lyrical impact of his works,heightening the conveyance of his inner heartache and strengthening the emotional appeal of his poetry.
