Shelley, P. B.(Percy Bysshe Shelley, 1792 ~ 1822) is a famous British democratic poet. Born into a rural landlord family, he entered Oxford University at the age of 2 and was expelled from the school for writing anti-religious philosophical papers. After joining the society, he was forced to move to Italy in 1818 because he wrote poems to encourage the British people's revolution and supported the Irish national democratic movement. In Italy, he still actively supported the national liberation struggle of the Italian people. In 1822, when he crossed the sea, he was unfortunately drowned in a storm.

Shelley is as famous as Byron as a famous romantic poet in Europe. His works are passionate and philosophical, and his poetic style is free and unrestrained, constantly changing in heaven and earth, time and space, and ghosts and spirits, and he is also used to fantasy symbolism and ancient myth themes. His best works include the long poem "Fairy Queen Maibu" (1813), the fantasy lyric story poem "Islamic Rebellion" (1818) describing the anti-feudal uprising, the political poem "The Rank of Tyranny" (1819) accusing the Manchester Massacre, the political poem "Ode to Freedom" (182) supporting the Italian national liberation struggle, and "Expressing revolutionary enthusiasm and victory belief"

The ultimate goal of Shelley's romantic ideal is to create a new world where everyone enjoys freedom and happiness. He envisions himself as a messenger flying day and night, a cloud floating in the blue sky, a lark soaring in space, and even a westerly wind in late autumn. He is a disseminator, eulogist and summoner of the new world ideal. He painted a beautiful picture of this new world with beautiful language and rich imagination, and boldly predicted: "If winter has come, can spring be far behind?" Therefore, Engels praised Xuecai as a "genius prophet"
